Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a primary battery is used as an operating power source for the remote control, then the remote control can be used conveniently, but the purchase cost and replacement inconvenience increase, and corrosion occurs in the power supply part over time
Solution Approach 1:
The patent changes the fundamental parameter of the power source from primary battery to capacitor module, enabling rechargeability and eliminating the need for frequent replacements and separate power supply units
Solution Approach 2:
The invention extracts and eliminates the separate power supply unit by integrating the capacitor module directly into the remote control body, simplifying the overall structure and reducing corrosion risks
2Duration of action of moving object
If a lithium-ion polymer battery is used as a rechargeable power source, then the one-time use problem is solved, but the number of charge and discharge cycles is limited and chemical pollution still occurs
Solution Approach 1:
The patent changes the chemical composition parameter of the power source from lithium-ion polymer to capacitor material, enabling unlimited charge-discharge cycles and eliminating chemical pollution while maintaining rechargeability
Solution Approach 2:
The invention replaces the limited-life chemical battery with a durable capacitor module that can be recharged indefinitely, effectively creating a non-disposable, environmentally friendly power source
3Power
If multiple capacitor cells are connected in series to increase voltage, then the charging voltage is sufficient, but the risk of overcharge and transient voltage increases
Solution Approach 1:
The patent introduces a capacitor protector as an intermediary device between the series-connected capacitor cells and the charging circuit, which actively monitors and controls the charging process to prevent overcharge and transient voltage while maintaining sufficient charging voltage
Solution Approach 2:
The capacitor protector implements feedback control by continuously monitoring the voltage and current during charging, and adjusting the charging parameters in real-time to prevent overcharge and transient voltage conditions
4Productivity
If a high current is used for rapid charging, then the charging speed increases, but the risk of overcurrent and transient current damage increases
Solution Approach 1:
The capacitor protector serves as an intermediary that enables rapid charging by controlling and limiting the charging current, allowing high current flow while preventing overcurrent and transient current damage to the capacitor cells
Solution Approach 2:
The capacitor protector provides beforehand protection by pre-establishing current limits and protection mechanisms that cushion against potential overcurrent and transient current damage during rapid charging
