What about development smart internal lock

It would be interesting, but;

Development costs?

Hardware: ????
Server software, plus server rental costs, plus systems like backing it up, security etc. At lest 12k a year,plus probably 50k development.
App software, which you will need to connect the bluetooth lock to the internet: Could be 20k, with maintenance perhaps 10-20k pa.

Since you lack so much, what do you bring to the party?

 

Good luck then

The only way to make the product profitable is to have a much larger customer base than locked dudes.
The berg watcher lock was repurposed from much older keyway locks, there were tens of thousands in production.
2nd hurdle is the size and working environment. Miniaturized in a very inhospitable invironment are two very difficult hurdles for the lock.
Only a few options for a good remote controlled key box, even less for a regular padlock. Building something small enough for a chastity device?

 

With a background in electronical engeneering, I will argue that this is not possible with current tecknology. You need a battery, cpu, wifi, engine og lock mechanics all waterproffed in a VERY small space.

The software is 1% of this project.

 

Regarding the battery - you should think outside the box, literally.

There's no need to have a battery inside the lock.
Just have two contacts and connect a battery when you want to operate the device.
(That's how the emergency backup power supply is provided on electronic safe locks.)

 

Perhaps you could design a new lock specifically for chastity and then you could 3D print devices to fit it?

 

In my opinion, the smart lock is a nice forward looking concept that may not have value realized soon. The current work around seems to be fine—standard lock boxes used for real estate and short term rentals.

 

Agreed, I just came here to mention this approach

same concept used here:

All the lock needs is a planetary gear actuator and a cryptographic chip. A physical key holds the battery and does some variation of challenge/response to the embedded chip, and talk to the internet to check for any release code from the keyholder/timer/remote AI system.

Dependant on the chastity design, you could swap the actuator for a Nitinol shape memory alloy. This is the same unlock mechanism used in local Amazon drop-off locker cabinets.

The latches are capable of holding around 50Kg

Something that just popped into my head are the greenhouse ventilation actuators that use wax expansion to control a vent pane, this concept could slowly latch a lock mechanism using the wearer's body heat alone, and a Nitinol wire could then pop open that latch

If you chose to include a battery then I'd still skip the Bluetooth interface, but instead incorporate a number of extremely low power anti tampering sensors, like detecting external vibrations from a sex toy or bending stress on the penis cover. Also logging the steel belt's nominal 37°C temperature history to confirm that it has been attached to a human body for as long as the wearer has claimed.

You can add a 2D barcode sticker.
eg: https://www.aliexpress.com/item/1005005467305143.html
so that a system could periodically visually check locked integrity via a 2G barcode scan of the belt's QR serial number and belt seal cover
eg: https://www.aliexpress.com/item/1005005830040946.html

Future AI vision systems could monitor a belt wearer 24/7, enable AI supervised removal for bathing and defeat attempts to conceal a cut belt from the system, so the actual maintenance of this locked state becomes less of a chore for the keyholder.
Doubtless this will be a nice side hustle for women in the future, their mere existence in the control loop being all that is required.
