Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an ordinary lithium battery is used directly, then high energy density and low weight are achieved, but voltage exceeds rated range causing safety hazards and unstable operation
Solution Approach 1:
A voltage regulation circuit board is introduced as an intermediary between the lithium battery and the induction garbage bin motor. This circuit board includes voltage detection modules, regulation modules, and protection circuits that clamp the battery voltage to match the rated voltage range of the motor, preventing overvoltage damage while maintaining the high energy density benefits of lithium batteries
2Reliability
If voltage clamp processing is implemented, then working voltage is maintained within rated range, but device complexity increases
Solution Approach 1:
Multiple functions including voltage detection, regulation, overcharge protection, over-discharge protection, and over-current protection are merged into a single integrated voltage regulation circuit board. This consolidation reduces the number of separate components and simplifies the overall device structure while maintaining comprehensive voltage management
3Reliability
If high-voltage pulse processing is implemented, then normal operation is ensured, but energy loss occurs
Solution Approach 1:
The voltage regulation circuit board includes a recovery module that captures high-voltage pulses generated during motor operation and converts them into usable energy. These pulses are stored in energy storage capacitors and reused to power the motor, transforming what would be wasted energy into a beneficial resource that extends battery operation time
