Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electromagnetic wave with high electric field intensity is supplied to power storage device for supplying high electric power in short period of time, then power supply speed is improved, but harmful effects on human body and regulatory compliance deteriorate
Solution Approach 1:
The power storage device performs periodic charging operations by receiving electromagnetic waves in intervals, rather than continuous high-intensity exposure. The control circuit manages charging cycles to achieve necessary power supply while allowing rest periods that reduce cumulative exposure to electromagnetic fields, thereby maintaining productivity while mitigating harmful effects on human body
Solution Approach 2:
The system dynamically adjusts the charging parameters including electromagnetic wave intensity and duration based on real-time conditions. The control circuit monitors charging state and modifies power reception to achieve optimal power supply speed while keeping electromagnetic exposure within safe limits, resolving the contradiction between speed and safety
2Reliability
If electromagnetic wave attenuation occurs during charging, then charging efficiency is improved for individual devices, but complete charging of multiple devices deteriorates
Solution Approach 1:
The system segments the charging process by individually managing power distribution to multiple power storage devices. The control circuit identifies each device's charging state and provides targeted electromagnetic wave energy, ensuring that attenuation affecting one device does not prevent complete charging of others, thereby achieving both reliability and productivity
Solution Approach 2:
The control circuit incorporates feedback mechanisms to monitor the charging state of each device and adjust electromagnetic wave distribution accordingly. When attenuation is detected in certain areas, the system increases power to those specific devices while maintaining appropriate levels for others, ensuring complete charging across all devices while optimizing overall charging efficiency
3Duration of action of stationary object
If power supply to load is continuously maintained, then operational continuity is improved, but unnecessary power supply and energy waste deteriorate
Solution Approach 1:
The power supply to the load is dynamically controlled based on actual power needs. The control circuit monitors the operational state and adjusts power delivery in real-time, maintaining continuity when needed while reducing or stopping supply when not required, thereby achieving operational continuity without unnecessary energy waste
Solution Approach 2:
The power storage device autonomously manages its own power supply to the load by monitoring its own charging state and power requirements. This self-service capability ensures that power is supplied continuously when needed without external intervention, while automatically reducing waste by stopping unnecessary supply, resolving the contradiction between continuity and energy loss
