Sin Stainless steel is inert - it doesn't react with other substances, which is why it works so well for piercing and surgical instruments (and chastity belts).

There are actually many grades of steel that are classified as "stainless". Unfortunately just stating "stainless" does not qualify the exact variant of the steel but only that it should not rust (which can be achieved in different ways).
Also depending on what kind of steel you have, there are variable amounts of other metal included, some of which might cause issues of worn next to the skin (e. g. nickel).

    You are right. This is less medical knowledge but more basic understanding of physics and paired with common sense.
    Pressure = force / area

    As a belt by necessity is tight against the skin so that it can prevent access to the locked parts, a certain force pressing against the skin is inevitable. But distributing that exact same force over a larger area reduces the effect it has on the skin.

    In real life comparision:
    Try to cut your steak with a blunt knife (meaning the surface area of the edge is actually large and broad) or do it with a freshly sharpened blade (which means a very narrow edge and therefore very small area), then you see the difference.

        Sin Not so the foam padding you're thinking of

        No, I was referring to hard, impermeable plastic.

          curious Pressure = force / area

          Absolutely true, but a belt would be far more comfortable with front and rear pressure plates made of hard, impermeable plastic (or metal coated with said plastic).

          I like my idea and I’m sticking with it.

            I had also wanted to assemble a “dream team” of medical doctors:

            An orthopedist, because he would know how to write a prescription in a format that the orthotist would understand.

            A urologist, to certify that we’re not doing anything really bad in regard to the male organs.

            A psychiatrist, who would certify that the belt is “medically necessary” for me in a purely psychological sense.

            A specialist in Eastern medicine, someone who speaks the language of chakras, meridians, and pressure points.

              The belt should always encourage good posture; it must never encourage bad posture.

              Some years ago, I was also working on an idea I referred to as “the unequal-length A-arm suspension”, although there were never any actual “A-arms”.

              The idea here was to allow for a small amount of relative motion between the front and rear pressure plates. There would be a total of eight ball-in-socket joints, four in the front, and four in the rear. There would be two metal bars or tubes on each side of the wearer’s body.

              However, I have largely put this idea on the shelf. I now believe that relative motion between the two plates is probably not necessary and would probably not add value.

              I do, of course, retain the right to change my mind yet again on this subject.

                I'm not a doctor and definitely not claiming to be one - there are others on here who are far more knowledgable than me in that regard - but I can help with two of those! I'm a yoga teacher and I work in occupational therapy, mostly involving pelvic dysfunction and rehabilitiation (postpartum for women or post-op prostate patients in men).

                It would help with movement but not with weight! Also it probably wouldn't be discreet. That's why I'm a fan of the cable solution, because it is lightweight and sits flat. I've not worn one of these but I must say it looks pretty good from my point of view...

                    Fs is soo expensive though

                    youdontknowme

                    i agree, the more surface, the less pressure on individual points and the more wearing comfort.

                      I should like to add that I’ve been incubating and developing the ideas expressed here on this thread for some 30 or 31 years now. During this time, the essential elements of my design have not changed. If I’m capable of being wrong about any of this, then I guess my entire adult life has been wrong.

                      It would appear that every time I post any kind of original idea to this forum, I end up with four or five know-it-all ignoramuses telling me why it won’t work/it isn’t any good/it should be discarded in favor of some other, more prosaic approach.

                      I find it extremely wearying and soul-destroying to feel that I have to respond to each and every one of your uninformed comments, questions, and nitpicking objections.

                      Or, as Harry Truman astutely put it, “If I were to attempt to read, much less respond to, all of the criticism that has been leveled against me, this office might as well be closed for any other business.”

                      One might also recall Spiro Agnew’s reference to “the nattering nabobs of negativity”.

                        Huh? No one is attacking you. I think it's a great idea. You said you wanted a team of professionals and there are several people here with medical backgrounds... @Foxies is a retired doc, and @Ines is a soon-to-be doc. I work with the type of medical devices you're talking about somewhat regularly.

                        Isn't the point of sharing ideas to find out what won't work or what can be improved? Or are you going to assemble a team of specialists and just tell them they're wrong anyway, because you've been thinking about it for a while?

                        The only issue I have with your design is that you said you wanted to put pressure on the front of the body. We can't do that easily. It will get uncomfortable really quickly, and it can interfere with digestion and blood flow to your vital organs. Bowel obstructions and ruptures are not fun. No one is going to make a brace that compresses your abdomen unsupported.

                        But hey, I think it's cool that you're thinking about these things. Good luck in your endeavours, I hope it works out for you.
                        🙂

                          @audioguy58 , I like your threads, are very original.
                          Fresh air, and your ideas and your imagination is your merit.
                          But I think, as @Sin that nobody tries to attack you.

                          If you do not want people to actively engage with your ideas (and Engagement for the most part means critical but constructive comments rather than just applause), why do you share them in a public forum in the first place?
                          If you want one-way communication only, just create a website where you control all of the content.

                            sorry, this is a discussion forum and everyone has a different opinion. the decision is ultimately yours, but if you post something here for discussion in a thread, you have to expect that there will be users who do not share your opinion.

                              I guess for a certain kind of person, tearing down the creative work of others is their only source of joy in life.

                                no one does that, some of your ideas are not bad at all and if someone criticises something, then only to improve the ideas. 🙂

                                  When I created this topic, I did do with the expectation that other people would and should post their ideas regarding the perfect belt. If you have ideas of your own, by all means step up to the mic and let us hear them.
