Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a rechargeable battery unit is used to supply power to an electric generator, then the generator can operate without gasoline and emit no fumes, but the power supply duration is limited to a very short period before requiring recharging
Solution Approach 1:
The system enables continuous operation by having the generator automatically recharge the battery unit during its operation. The generator supplies power to both the external load and the battery unit simultaneously, ensuring the battery remains charged and ready for immediate use without interruption to the power supply.
Solution Approach 2:
The system performs self-recharging through an automatic switching unit that directs the generator's output to recharge the battery unit when the battery power level decreases. This self-service mechanism eliminates the need for manual intervention or external recharging infrastructure.
2Duration of action of moving object
If a self-recharging system is implemented using the generator to recharge the battery, then the power supply duration is extended, but the system complexity increases with additional switching units and control mechanisms
Solution Approach 1:
The generator serves multiple functions: it powers the external load, recharges the battery unit, and can operate independently when needed. This multi-functionality reduces the need for separate dedicated recharging equipment, thereby limiting the increase in system complexity.
Solution Approach 2:
The automatic switching unit monitors the battery unit's power level and automatically activates the recharging function when the battery power decreases. This feedback-based automatic control simplifies operation and reduces the need for complex manual control systems.
3Duration of action of moving object
If gasoline is used to power the generator, then continuous operation is achieved, but fuel expenses increase and harmful emissions are generated
Solution Approach 1:
The system uses its own generator output to recharge the battery unit, creating a self-sustaining power system. This eliminates the need for external gasoline fuel, achieving continuous operation without the harmful effects of fossil fuel consumption.
Solution Approach 2:
The system converts the generator's electrical output, which would otherwise be wasted, into useful recharging energy for the battery unit. This transforms excess electrical energy into a beneficial resource that extends operational duration without requiring gasoline.
