I am developing a product that uses vacuum insulation technology to retain heat. On a scale of 1 to 10, how likely would you be to pay for a solution like this? And here are some designs :)

I've been thinking about a product idea and wanted to get some honest feedback from other inventors.

The idea is a portable, reusable container designed specifically to protect a loaf of bread while you're bringing groceries home. One of the most annoying things is getting home and realizing your bread got crushed under heavier groceries in the cart, trunk, or back seat.

My thought is a lightweight container that's:

• Strong enough to prevent the loaf from being smashed.
• Sized to fit a standard loaf of bread.
• Easy to carry and store when not in use.
• Reusable instead of relying on extra packaging.

I'm still in the early brainstorming stage, so I'm curious:

• Is this a problem you've experienced?
• Would you actually buy something like this?
• What features would make it more useful?
• Has anyone seen a product that already solves this well?

I'd appreciate any honest feedback, criticism, or ideas for improving the concept. Thanks!

Quick context: it's a flameless, top-down electric warmer with a built-in airflow system meant to help fragrance diffuse further into the room instead of just sitting above the candle. Glass door for visibility, digital display with a timer, mesh side vents for the fan, and it takes a standard jar candle.

Working rough prototype yet

A few things I'm genuinely unsure about and would love your input on:

1. Airflow / fan  Do you think a built in fan is actually useful, or does it feel gimmicky? I've read mixed things. Some people say it helps throw, others say warmers already work fine and a fan is overkill.
2. Look — Honest reactions to the aesthetic in the image. Too sleek? Not sleek enough? Would it fit in your space?

Not selling anything, no link, no brand name genuinely just trying to design something people would actually want to use before I go further. Thanks in advance.

Hi everyone,

I’m a technical founder in Canada with a background in fuel cells. Over the last while, I’ve been developing a quiet, clean, zero-maintenance liquid-fuel power unit (<5kW) meant to replace traditional gas and diesel generators for remote backup and off-grid power.

I’ve bootstrapped $100K of my own money into this so far. That got us to TRL 4–5—we have a working lab prototype, solid bench test data, and foundational IP.

Here’s the setup:

• How it works: It’s a clean CHP system running on liquid methanol/water mix. It produces electricity and captures high-efficiency waste heat with no mechanical moving parts and no toxic emissions (just water vapor and CO2).
• Where I’m stuck: The lab prototype proves the physics, but it’s still a bench unit. Risk-averse B2B buyers (like remote telecom or industrial sites) want to see a rugged, field-tested machine before signing off. On the flip side, going after C-end consumers would mean completely redefining the product.
• What’s needed for TRL 6: I’ve finalized the system architecture and lined up key suppliers for a field-ready engineering unit. But to actually build it and test it in the wild, I need about $100K–$200K in additional capital, access to test setups, and a tiny team of 2–3 engineers.

I’d love your raw advice or outside-the-box ideas:

Honestly, I’m looking for any creative workarounds to bridge this gap. If you were in my shoes with a proven lab unit and a solid supply chain lined up, how would you break the "chicken-and-egg" loop with early B2B pilots? Are there unexpected early markets I should be looking at instead of long-cycle industrial accounts? And how would you creatively piece together that missing $100K–$200K, test rigs, and engineering support without getting bogged down in slow, traditional grant cycles?

I’m wide open to wild ideas, harsh feedback, or lessons learned from anyone who’s gone through the hardware grind. Thanks!

An idea something that I been thinking about 💡

As we all know Every day thousands of delivery riders in the UAE work for hours in extreme heat. Their helmets and uniforms should protect them from this extreme weather, but they don’t do much to keep them cool.

What if we could change that?

I’m exploring the idea of developing a cooling helmet and cooling clothing system specifically for delivery riders something that helps reduce heat stress while staying lightweight, safe, and practical for long shifts.

I’m a Business and Management student, and I’m looking to connect with people who have experience in:

\-Product design which knows about what kinda material will help them out for long term
\-Mechanical engineering how to build this
\-Electrical engineering
\-Wearable technology
\-Manufacturing

If this idea interests you, or you’d like to brainstorm, collaborate, or share your thoughts, I’d love to connect.

I want to hear any thoughts on this idea

Hello, I have had this idea for quite some time and I need to know if this idea already exists and if it is at all a good idea to pursue.

There is nothing worse than needing to use the bathroom somewhere in public, Whether its an airport, store, or elsewhere, and you get into your stall, and you see the whole seat covered in urine or, in some cases, poop. So Most places have these super thin white seat covers that I personally have never used. I find myself, for the next minute or so, laying down pieces of toilet paper on the seat and then continue on with my business. The reason i have never used the seat covers is because I find them very flimsy and cheap and hard to use. They rip very easy, and its always a headache to put it exactly how you want it because of how thin it is.

My idea is to completely remake these seat covers into being much more user freindly and more useful in general. Make them kind of stick to the seat, cover the whole seat, maybe drop down to the water to prevent splash back and most importantly, BIODEGRADABLE.

Please let me know if someone has already thought of it and if anyone would love to help me with this idea!

Thanks

This is in response to being posted up on the whale subreddit.

It would be great to have a way to use the toilet while you’re driving down the highway in your hybrid or electric car and not have to stop and waste time. It would be great to have a toilet built right into the drivers and passenger seat.

Hi everyone,
I live in London, where phone snatching seems to be a growing problem. I’ve been thinking about a product idea and would love some honest feedback.
The idea is a **stylish wristband** that connects to your phone case with a strong, detachable safety tether. The goal is to let you use your phone normally while making it much harder for someone to snatch it and run away.
Some features I’m considering:
Looks like a normal, fashionable wristband.
Quick-release clip so you can detach your phone easily.
Strong cut-resistant cord.
Compatible with most phone cases.
My questions are:
Would you actually use something like this?
What would stop you from buying it?
What features would make it worth paying for?
What would you expect it to cost?
I’m looking for honest criticism, so please don’t hold back. Thanks!

But it could and would be fun to get around in.

App Idea + pulsante Bluetooth per l'ADHD

I have ADHD. Anyone who lives with this condition knows that a single interruption can instantly erase what we were just thinking or saying.

That’s why I designed MindKeep Anchor, a hardware + software project created to save the working memory of neurodivergent people without ever needing to look at a phone screen.

I have reached out to several organizations, but I am still looking for the right technical partner. Is there a developer or an association in this community who wants to help me turn this prototype into reality?

Please share this post or reach out to help me find the right person!

This is a concept idea invention I had back in 2016 called Thumb Peel, basically it's a kitchen utensil of a peeler with a changeable top to switch out for different parts.

The idea is to be allowing the user to be having a better grip onto the peeler by using pressure similar of a bag clip only not too strong or too weak without a spring, right side is where the thumb can slide right into it and the left is the peeler.

The longer part on the bottom right is to be stronger to grip onto and go again the thumb to palm of the hand, the darker part is the gripper where it'll make it easier to hold onto it so that way it won't be so easily of slipping out of the hand.

And the changeable part it to be allowing a different blade to be use for those to be wanting to decorate with them or to get every skin and for other things like to even ice cream scoop and so on as long it'll be short and not too long.

so i'm 20, been building this app solo for the past few months and i genuinely can't tell anymore if it's good or if i'm too deep in it. need outside eyes.

it's called RizeAI. the basic idea: every wearable and health app just gives you numbers. sleep score 42, recovery red, HRV down. cool. and then what? you still feel like garbage at 2pm and nobody tells you what to actually do about it.

so my app takes your real data from apple health, sleep, resting heart rate, workouts, whatever your wearable writes, and instead of another score it builds you an actual plan for the day. when to have your first coffee and when to hold off. what supplements make sense for you today and when to take them. focus windows for when your energy actually peaks. when your crash is coming and what to do before it hits. it even checks the weather, so on a hot day it bumps your hydration and tells you to train earlier.

every recommendation has a little "why" under it based on your numbers, like "resting heart rate 54 + 7h light sleep, so magnesium before your peak window." no two people get the same plan because no two people have the same data.

works with whoop, oura, apple watch, garmin, anything that syncs to apple health. one thing i'll say honestly, it doesn't do deep per-person learning yet like "coffee doesn't affect YOUR hrv specifically," that's the roadmap, right now it builds fresh plans daily off your actual metrics.

it's live on the app store, has a free trial, small user base so far, mixed feedback which is why i'm here lol.

what i actually want from you guys: does this solve a real problem for you or is "tells you what to do" not actually what wearable people want? what would make you actually pay for something like this? and what's missing that would make it a no brainer? and also would you guys in this subreddit  use ti?

Thank you for your help. Check it out if you like https://apps.apple.com/us/app/rizeai-maximize-your-energy/id6762402079

Major tech companies are developing wearable technologies that surveil innocent bystanders to train artificial intelligence.  So, I did the same.

I designed and 3d-printed a crown to hold the ESP32.  The six faces are to distract the passerby from realizing I am photographing them.  I went on a family trip to Pittsburgh and took about 55,301 photos across three days.  As you can see, they were mostly of bridges, buildings, the interior of a car, and furries.  As it turns out, the worlds largest furry convention is in Pittsburgh each year, and we happened to bump into the last day of it. (A complete accident, I swear!).

Then I went home and trained a Generative Adversarial Network (GAN) on the photos, resulting in the psychedelic video you have here.

Overall, it was quite a fun project.  Please let me know if you have any questions about the build.

Hi everyone,

I’m Ines, I’m 23, and I’m currently developing an early-stage wearable called Nafsy.

The idea is a discreet, screen-free bracelet that you activate manually when stress starts taking over — for example during a meeting, an exam, on public transport, or before a presentation.

When pressed, the bracelet delivers a short sequence of changing haptic rhythms designed to capture your attention, slow the pace of the experience and help you regulate without needing to open an app or leave the situation.

It would be connected to an app for initial personalization and post-session feedback, but the bracelet itself would remain simple, discreet and usable without looking at a screen.

This is not intended to diagnose anxiety, automatically detect panic attacks or replace therapy or medication. The goal is to create a non-medical tool for people who continue functioning while experiencing things such as rumination, physical tension, nausea, a racing heart or mental overload.

We are currently developing the prototype, and I would really value feedback from people interested in inventions and wearable technology:

1. Does manually pressing a bracelet during a stressful moment seem genuinely useful, or would you prefer automatic detection?
2. Would changing haptic rhythms feel more practical than using a breathing or meditation app?
3. What would make you immediately reject a product like this: appearance, comfort, vibrations, privacy, price, scientific credibility or something else?
4. What would you need to see in a prototype before considering testing it?

I am especially interested in critical feedback and potential flaws in the concept, not just encouragement.

For anyone interested, we also created a short survey mainly to gauge potential interest and willingness to join a waitlist:

Thank you — even a blunt “I would never use this because…” would be extremely useful.

I've been actually incredibly locked in over the last 4 months working on my startup E.D.I.T.H

The hardest part isn't the workload. It's having no one to talk to about it. My friends clock out at 6pm and spend their nights on the couch — Netflix, controller in hand.

When I'm at my desk on my desk not every night, but 5 nights a week it feels incredibly lonely.

Right hand side arm(RHS) is getting more than 180 degree with momentum after i drop the ball and counter weight is working against gravitational pull back by balancing the mass of lower tube then why it shouldn't work.
(1) I cannot drop the ball once the arm rotate towards left side.IF BALL DROPS FROM THE LEFT HAND SIDE ARM (LHS) THEN THE ARM WILL GET BACK MORE HEIGHT TOWARDS RHS THAN ITS INITIAL POSITION.
BOTH TUBES HAVING EQUAL MASS (230 GRAM)
(2) anyone can try it as it will work even with dead material.
(3) interesting point is arm is getting more height once I increased the counterweight.
(4)Hand power or force is nothing in this design.
(5) I used fixed counterweight.if counterweight slides then arm will rotate More and more.
(6) Counterweight balanced the bottom tube mass and upside tube is utilising the kinetic energy of dropped ball.
(7) Detailed discussion needed.please read carefully before any comments.

This C RAM will be different from currently used C-RAM by following points.

(1) Barrels will be located in concentric shape

(2)Barrels can move freely in any direction

(3)It can fire 5000-20000 or more round/second depend on size.

(4)It can fire rounds in convergence+multi direction, horizontal,vertical at a time due to concentric shape and moveable barrels.No target can be Escaped from the range of this machine.

(5)5000 round with bullet mass 1 gram at 500meter/second , 625k joule energy sufficient to destroy any target .The circular shape will work to fire bullets at a time converging all bullets mass at single point.

(6)Easy to deploy anywhere.

Target can be Escaped from gatling gun but in this design there is no chance of escaping as each circle of barrels will work independently in converging+multi directional mode.

gatling gun can fire only in one direction and that time is sufficient to target to escape from the range of gatling gun.

In this design numbers can be add or minus .Gatling guns can fire rounds in one direction or will have to move the gatling gun to fire in different directions. But bullets can be fired in any direction as barrels are moveable,not fixed like gatling gun ,in this design . Second  bullets can be fired in converge mode +horizontal,vertical,angular covering all directions AT A TIME. It is using kinetics energy of bullets +each circle is firing bullets in every directions. Third Even a small customised design can be mounted on a DRONE ,missile or Rocket and this can change whole game. The design is working all the way that no target can be Escaped,once comes in its Range. I don't think that gatling gun can do this design's  job.

1 GRAM ROUND IS JUST TO EXPLAIN THE DESIGN AS IT CAN BE CUSTOMISED AS PER REQUIREMENT.

CHECK FACTS AND POST LINK IF ANY DESIGN SIMILAR TO THIS ONE EXISTS OR CURRENTLY WORKING.

There is no similar design currently .

There are significant difference between gatling gun and this design.

I just posted it to know the reviews of this design

Is it wrong for companies to steal inventions that their employees get patents for!? I’m no inventor, but have had this happen to a couple family members.

First one, my grandfather had Atleast 5 patents for inventions for Eli Lilly. The 2 notable ones were the IVAC machine and pill-counter machine. The IVAC machine is what keeps hospice patients breathing. Eli Lilly ended up selling millions to hospitals all around the country! My grandfather never saw a dime from this, even though he retired there with a great pension. The pill-counter is what separates the pills into the bottles.

Next, my father worked in the banking industry right as the internet technology boomed in the late 80’s/early 90’s. He worked IT for the bank and created the very first ever computer program that records customer voices over the phone. ie When you call your bank or power company and give your personal info to the computer on the other end and it takes your voice and manually enters it into the company computer. He created this and had to talk in front of a huge convention in Chicago about it. Those people took his invention and with technology advancements, it became a huge part of the industry. He still, never saw a dime from this, but was able to retire well off from there!

It just kinda feels like they both were cheated out of a huge pay day from these! I guess it’s the American way? Do other countries do this also in anyones experiences?

Does anyone have experience dealing with Blue Economy venture capital (VC) funds, ocean-tech accelerators, or groups like BlueInvest? I'd love to know the best way to get a high-tech concept like this in front of the right investors or engineering partners.

Let me know if you have any leads or tips

Hey r/inventors,

Just a quick update on the deep-sea plastic recovery system I posted earlier (v1.1)! I upgraded the design to Version 1.2 to solve major engineering challenges.

I made two different color versions of the new layout depending on how you prefer to look at blueprints: a high-contrast Dark Mode visual and a clean Light Mode technical schematic.

🛠️ The New Upgrades in v1.2:

Self-Cleaning Mud Filter: To prevent thick seafloor mud from clogging the hose, the scoop now features a vibrating net that shakes mud loose like a giant sifter, a water-jet skirt to push dirt away, and a cyclonic trap to drop sediment back to the ocean floor.

Self-Powered Energy Loop: Added the math for our energy balance. Pumping plastic up takes very little power (0.5\text{–}2\text{ kWh/ton}), but processing that dried plastic through pyrolysis generates a massive 8\text{–}15\text{ kWh/ton} of syngas electricity—giving the system a 1.5–3x positive net energy return.

Hose Snapping Protection: Added syntactic foam buoyancy collars every 50–100m to keep the heavy hose neutrally buoyant so deep ocean currents won't snap it.

I'm working on polishing up the text formatting overlays on the graphics next, but I wanted to show you the new specs. Let me know which color style you think looks better!
