Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate power supply and sensor are used for counting functions, then the device can perform sensing and power supply functions, but the device occupies more space and consumes more power
Solution Approach 1:
The patent merges the power generator and sensor into a single integrated unit. The power generator generates electrical signals during operation that directly reflect the operational state, eliminating the need for separate sensors. This combination reduces the number of components, saving space and reducing power consumption while maintaining both power supply and sensing functions.
Solution Approach 2:
The power generator serves multiple functions simultaneously: it generates electrical energy to power the device and provides sensing signals for counting operations. This multi-functionality allows the device to perform both power supply and sensing tasks with a single component, improving adaptability while reducing overall power consumption.
2Adaptability or versatility
If separate power supply and sensor are used for counting functions, then the device can perform sensing and power supply functions, but the circuit loses energy in energy transmission
Solution Approach 1:
By combining the power generator and sensor into one unit, the patent eliminates the energy transmission interface between separate components. The electrical signals generated by the power generator are used directly for sensing without requiring transmission through external connections, thereby eliminating energy loss in transmission while maintaining both power supply and sensing capabilities.
3Extent of automation
If friction-based electromagnetic power generator is used for self-powering, then the device can generate electricity, but the counting can only be performed after electric energy is accumulated and requires calibration
Solution Approach 1:
The system uses the electrical signals generated during power generation directly for counting operations without requiring separate calibration procedures. The inherent characteristics of the generated electrical signals provide the necessary information for accurate counting, allowing the device to be self-sufficient and eliminating complex calibration steps while maintaining self-powering capability.

AI summary
A mechanical energy-based self-powering counting system is provided. The system includes an electromagnetic power generator, a count measuring circuit, a count energy supply circuit, a controller and a wireless transmission module. The electromagnetic power generator is driven by an external device and produces an electric signal and outputs the electric signal to the controller after passing it through the count measuring circuit. The controller processes the received signal, updates a count according to certain programming rules and sends data to the wireless transmission module. The energy from the electromagnetic power generator flowing through the count measuring circuit can supply power to the controller. An energy storage module in the count energy supply circuit performs voltage feedback on the controller. The controller monitors the voltage of the energy storage module to control whether it enters a charging state.
