Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transmission systems use conventional wired charging methods for firmware updates, then firmware update capability is provided, but mobility and convenience are reduced
Solution Approach 1:
The wireless communication circuit is designed to perform multiple functions: it enables both power transmission control and firmware update capabilities through a single communication interface. This allows the system to maintain mobility and convenience while providing firmware update functionality without requiring separate wired connections.
Solution Approach 2:
The patent introduces a wireless communication circuit as an intermediary component that facilitates firmware transmission between the wireless power transmitter and receiver. This mediator enables seamless firmware updates through wireless communication, eliminating the need for physical wired connections while maintaining update capability.
2Productivity
If wireless power transmission systems lack firmware update capability, then device simplicity is maintained, but operational efficiency and compatibility are reduced
Solution Approach 1:
The system performs firmware updates proactively through wireless communication before operational issues arise. The control circuit monitors firmware versions and automatically initiates update transmissions, ensuring the system maintains optimal operational efficiency and compatibility without requiring complex manual intervention procedures.
Solution Approach 2:
The wireless power transmission system is designed to perform self-updates through the wireless communication circuit. The receiver can autonomously receive and install firmware updates transmitted wirelessly from the transmitter, eliminating the need for external wired connections or complex manual update procedures, thus improving operational efficiency without proportionally increasing system complexity.
3Ease of operation
If out-of-band communication is used for firmware transmission, then wireless communication capability is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic communication cycles for firmware transmission rather than continuous communication. The wireless communication circuit activates firmware update transmissions only when needed, using scheduled periodic checks to determine update requirements. This approach maintains full wireless communication capability while minimizing energy consumption by avoiding constant active communication states.
