Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If lithium ion secondary batteries are used for power supply, then the device can operate for extended periods, but the device size increases and deterioration occurs over time
Solution Approach 1:
The power supply system is segmented into multiple capacitor units that can be independently controlled. Each capacitor can be charged and discharged separately, allowing the system to achieve extended operation duration through cumulative capacity while maintaining compact individual unit sizes. The control unit manages multiple smaller capacitors instead of relying on a single large battery.
Solution Approach 2:
The invention changes the fundamental parameter of energy storage from chemical batteries to electrical capacitors. This parameter change enables rapid charging and discharging cycles without deterioration, while the total capacitance can be scaled by adding parallel capacitor units rather than increasing individual unit size.
2Duration of action of moving object
If lithium ion secondary batteries are used for power supply, then the device can operate for extended periods, but deterioration occurs over time
Solution Approach 1:
The invention employs capacitors that can be rapidly charged and discharged many times without deterioration. While individual capacitors have shorter energy storage duration compared to batteries, their ability to withstand numerous charge-discharge cycles makes them effectively disposable in terms of lifespan, eliminating the deterioration problem associated with lithium ion batteries.
Solution Approach 2:
The system uses periodic charging and discharging of capacitor units under control of the control unit. Multiple capacitors are charged in sequence or parallel, providing continuous power supply through periodic energy transfer. This periodic action pattern allows extended operation duration while each capacitor undergoes stress-free cyclic operation that prevents deterioration.
3Volume of moving object
If capacitors are used instead of batteries, then device size is reduced and deterioration is suppressed, but power supply capacity is limited
Solution Approach 1:
Multiple capacitor units are merged in parallel under the management of a single control unit. The total power supply capacity is achieved by combining the capacities of individual capacitors, allowing the system to provide extended operation duration equivalent to or exceeding battery performance while maintaining the size and reliability advantages of capacitor technology.
