Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If separate control interfaces and power delivery components are used, then system reliability is maintained, but power delivery capability and data transfer speed are limited
Solution Approach 1:
The patent combines separate power delivery and data transfer functions into a single fire pin interface. The fire pin pair simultaneously carries both power signals and data signals, eliminating the need for separate wiring harnesses for each function. This merging approach increases power delivery capability to 20W while maintaining system reliability through integrated control.
Solution Approach 2:
The fire pin interface is designed to perform multiple functions: it serves as both a power delivery conduit and a data communication channel. By making the fire pin universal for both power and data transmission, the system achieves higher power capability without proportionally increasing wiring complexity, as the same physical interface handles both tasks.
2Speed
If separate control interfaces and power delivery components are used, then system reliability is maintained, but data transfer speed is limited
Solution Approach 1:
The patent merges data transfer and power delivery into the same fire pin interface. High-speed data signals are transmitted alongside power signals through the dual-use fire pin pair, enabling data transfer speeds up to 500k baud while using the existing wiring infrastructure rather than requiring separate high-speed data cables.
Solution Approach 2:
The system dynamically switches the fire pin between different operational modes. The same physical interface can transmit power, transmit data, or perform both simultaneously depending on the operational requirements. This dynamic multiplexing allows high data transfer speeds without permanently dedicating separate wiring for data communication.
3Ease of manufacture
If existing vehicle wiring harnesses are utilized, then ease of installation is improved, but power delivery and data transfer capabilities are constrained
Solution Approach 1:
The patent changes the electrical parameters of the existing fire pin interface to support higher power delivery. By modifying the voltage and current characteristics of the fire pin signals while maintaining compatibility with existing wiring harnesses, the system achieves 20W power delivery capability without requiring complete rewiring of the vehicle electrical system.
