Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional energy storage systems are used, then the system can store energy, but the operational duration is limited to less than one hour
Solution Approach 1:
The system implements feedback by using the generator to convert mechanical energy from the motor into electrical energy, which is then fed back to recharge the battery. This closed-loop energy feedback mechanism allows the system to extend operational duration from less than one hour to over 22 hours by continuously replenishing energy during operation.
Solution Approach 2:
The system performs self-service through the feedback mechanism where the motor-generator assembly generates electrical energy during operation to recharge the battery autonomously. This self-charging capability eliminates the need for external charging sources and dramatically extends operational duration without requiring larger battery capacity.
2Duration of action of moving object
If the battery capacity is increased to extend operational time, then the energy storage capacity increases, but the system complexity and cost increase
Solution Approach 1:
Instead of increasing battery capacity, the system uses feedback control where the motor-generator assembly generates electrical energy during operation to recharge the battery. This approach extends operational duration from less than one hour to over 22 hours while maintaining the same battery capacity, thereby avoiding increased system complexity and cost.
Solution Approach 2:
The system changes the operational parameters by introducing a motor-generator assembly that converts mechanical energy to electrical energy during operation. This parameter change enables the battery to be recharged during operation, extending operational duration without requiring larger battery capacity or increased system complexity.
3Reliability
If external energy sources are used, then the system can maintain operation, but the system becomes dependent on external sources
Solution Approach 1:
The system achieves self-service by using the motor-generator assembly to generate electrical energy during operation, which is then used to recharge the battery. This self-charging mechanism makes the system independent of external energy sources while maintaining high operational reliability, extending operational duration to over 22 hours.
Solution Approach 2:
The feedback mechanism converts mechanical energy from the motor into electrical energy that is fed back to recharge the battery. This closed-loop energy system eliminates dependence on external charging sources, enhancing energy source independence while maintaining operational reliability.
