    I’m surprised that I’m the first to say “p-trap” drain. Self-maintaining, no moving parts, affordable as anything, protects the indoors from sewer gas, catches rings. Chefs kiss 200 years old and still great

    The 3.5mm audio jack. It’s so fundamentally simplistic from a manufacturing standpoint and circuitry standpoint that any headset you throw at it will work identically without fail (the key innovation being the speakers or headphones where the analog signal is sent to).

      I disagree. The connector is fragile, subject to dust, contacts can wear out and audio quality suffers. Faulty connection means you have to twist it the correct way to have audio. Tug on your cable the wrong way and the connector on your phone is broken. Multiple standards for pinout for microphone and stereo. May cause shorts because every ring touches when plugging in. Disconnects too easily if the connector is fatigued, no locking mechanism.
      At this point it would be better to reserve a few pins on a USB C connector to pass audio data. But not sure if analog can transmit fine with all the serial cables around it.

          Yes, and there are examples of headphones that do so, but it puts a lot of strain on the USB-C connector (and the audio quality is reliant on the phone’s internal DAC, which can suck).

        I’ll see your Bic and raise you Zippo!

        Just got my first one a while back, I bought it 2nd hand and it’s 7 years older than me and works better than any lighters I’ve borrowed off people over the years.

        Replacement parts and even completely new lighter inserts still fit the original cases from the 1940s until now. And if something does break beyond you ability to repair, They got a lifetime warranty with no proof of purchase needed!

          I loaned it out one day to light fireworks. Somehow they overheated and ruined the flint wheel…

          I have a zippo, I like that it’s easy to pour in liquid fuel and they are somewhat wind resistant but the fuel does evaporate away over time. I keep it in a plastic bag which does slow the rate of fuel evaporation though.

          Not sure what cheaper fuels could work well in it, that would reduce the cost of fuel that just evaporates then and I don’t use it that often so I suspect more is lost to evaporation than usage.

      In my Flat we still have a microwave that does not have a rotating plate. Insteadt it has a spinning rotor in the roof that deflects the waves in order to cook food evenly. It works well but it is needlessly complicated compared to modern microwaves.

        Most microwaves have a spinning wave stirrer in addition to the rotating plate. From the description here, it just sounds like either your plate rotation motor is broken or you’ve got a weirdly simple microwave.

            Usually it’s not inside the same chamber as the food as then it would be a nuisance to clean. You need to take a microwave apart to see the wave stirrer.

              The diagrams I’ve seen show the wave stirrer on the roof. The microwaves I’ve seen have the ceramic plate on the side where the magnetron is so there’s no space for a stirrer.

                if the diagram’s any good, it should show the wave stirrer in the roof rather than on the ceiling of the food chamber. There’s typically a waveguide to take the microwaves from the magnetron to the top of the chamber, then the wave stirrer is at the end of the waveguide to vary the angle that microwaves enter the chamber at. There’s usually something to stop food splashing/spraying into that section, though, e.g. an extra few centimetres of waveguide afterwards with a bend in it.

                  I understand what you’re saying, I’ve just not seen one with any indication of a wave stirrer. They all just shoot the beams from the magnetron through a ceramic plate on the side if the microwave. The top interior of the microwaves I’ve used (even one ones from Samsung and LG) had no holes or vents. Maybe it’s just an American thing?

                Of all the dangerous devices to disassemble, they’re one of the safest. A phone charger might still have 400V across one of the capacitors ten minutes after unplugging it (if you’re in a 230V RMS country, so have more than 400V peak-to-peak), but a microwave’s high-voltage section is only powered when it’s plugged in, and microwaves are so long wavelength that even if you reassemble the waveguide or outer case badly and leave gaps, there probably won’t be dangerous levels of microwaves escaping as gaps much smaller than the wavelength in question don’t compromise the Faraday cage.

        That’s fair. But the fact that MIDI 1.0 isn’t going away anytime soon shows how good it was from conception. From Sweetwater:

        Because MIDI 2.0 coexists well with MIDI 1.0, it’s likely MIDI 1.0 devices will continue to be produced in the future if MIDI 2.0’s features are not needed for a particular application. In developing MIDI 2.0, backward compatibility with MIDI 1.0 was always a priority.

        MIDI 2.0 is not about replacing the original specification but about adding features that enhance the spec with features users have wanted almost since MIDI 1.0 appeared.

    Maybe not perfect upon conception, but after a couple of decades from common adoption, the bicycle really didn’t change much. Sure, you can use lighter and more advanced materials, you can add an electric motor to it (though I wouldn’t classify it as a bycicle) but you can probably take a 100 years old bike and it would work just as good as a modern one.

        I did almost consider an internal gear hub for my bike but they are not common so not sure if parts of maintenance may be difficult to come by. Also not really sure how I could fit one myself. Maybe some day though, I think some can manage quite a few gears.

        Fine with a chain though, mine is wax instead of oil lubricated.

            Don’t they last a long time though? Presumably even more so if you are someone that benefits from a lower maintenance option. I use my bike multiple times a week, cleaning it after every use is just impractical and I often go out when it’s raining.

              Yes they do last a long time. They can be a great option. Just not easy to fix if something goes wrong.

              You don’t have to clean a regular chain that often, but it will last longer if you do. A regular chain is perfectly fine to use in the rain / snow/ etc.

              In my mind, I know the chain and cassettes will wear out, so when they do, I would rather have ones I can replace myself. But an internal geared hub is a great option as well. It is lower maintenance, but with the trade off that it is difficult to work on.

                I looked at prices for internal hubs with a decent number of gears, ahh fuck that! Its more than half the cost of my entire bike.

                Think I will stick with what I have now then, I get the full gear range at like a tenth of the cost. Learning to do maintenance on it sometime might be a good idea though.

          I only bought it because it’s necessary for belt drive, and I wanted a maintenance free commuter. My coworker also has one as a daily commuter, though on a traditional chain drive, and hasn’t had any issues with it.

    Solid body electric guitars- the first models have been in continuous production and are still available.

    https://en.wikipedia.org/wiki/Fender_Telecaster

    https://en.wikipedia.org/wiki/Gibson_Les_Paul

    There were earlier “electric guitars” but I’m thinking all inventions build on previous creations. I don’t think you’ll find many pure answers to OPs question. I think the closest you’ll find is going to be an advancement that produced a single step change in design that flattened the innovation curve forever after. I think the microwave oven was a great example.

    Electric fuses also come to mind. Little has changed since 1890.
