Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an onboard battery is used to power the mobile device, then the device can operate independently, but the operating life is relatively short requiring frequent replacement or recharging
Solution Approach 1:
The patent implements continuous energy transfer through a wireless power transmission system where a power transmission device transmits energy to a power reception device on the mobile device during movement. This continuous energy supply eliminates the need for periodic battery recharging, maintaining uninterrupted operation and resolving the contradiction between operating duration and interruption time.
Solution Approach 2:
The patent replaces the mechanical battery replacement or recharging process with a wireless electromagnetic energy transmission system. The power transmission device uses electromagnetic fields to transfer energy wirelessly to the mobile device, substituting the mechanical intervention of battery changes with a seamless energy transfer mechanism that eliminates operational interruptions.
2Reliability
If frequent battery replacement or recharging is performed, then the device can maintain operational capability, but task performance is interrupted
Solution Approach 1:
The wireless power transmission system enables continuous energy supply to the mobile device during movement, ensuring uninterrupted operational capability while maintaining task performance. The power reception device continuously receives energy from the transmission device, eliminating the need to pause tasks for recharging and thus preserving both reliability and productivity.
3Duration of action of moving object
If a wireless energy transfer system is implemented, then operating life is extended without frequent recharging, but the system complexity increases
Solution Approach 1:
The patent introduces a wireless power transmission system as an intermediary between the power source and the mobile device. The power transmission device and power reception device work together to transfer energy wirelessly, extending operating life while distributing system complexity across separate components rather than requiring a complete system redesign.
