Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple ground terminals are used in the rear alarm sensor assembly, then the system can provide stable grounding connections, but the system size, cost, and complexity increase
Solution Approach 1:
The patent merges multiple ground terminals into a single ground terminal by introducing a determination device that dynamically connects identification terminals to ground based on their determined states. This consolidation reduces the number of physical ground terminals while maintaining grounding stability through active determination and connection management.
Solution Approach 2:
The patent employs a dynamic grounding system where the determination device actively determines the state of each identification terminal and dynamically establishes ground connections as needed. This dynamic approach replaces static multiple ground terminals with a single ground terminal that is selectively connected through controlled switching, reducing complexity while preserving reliability.
2Reliability
If multiple ground terminals are used in the rear alarm sensor assembly, then grounding coverage is improved, but the number of ground lines and installation complexity increase
Solution Approach 1:
The patent combines multiple ground connections into a single ground terminal infrastructure. The determination device manages connections to multiple identification terminals through this single ground terminal, reducing the number of ground lines required and simplifying installation while maintaining comprehensive grounding coverage across all sensors.
Solution Approach 2:
The single ground terminal serves multiple functions by dynamically connecting to different identification terminals based on their determined states. This universal ground terminal replaces multiple dedicated ground terminals, reducing installation complexity while maintaining grounding coverage for all sensors in the system.
3Reliability
If multiple ground terminals are used, then system reliability is maintained, but the cost and size of the assembly increase
Solution Approach 1:
The patent merges multiple ground terminals into a single ground terminal configuration. The determination device enables this single terminal to serve multiple identification terminals through dynamic connection management, reducing the quantity of ground terminals and associated materials while maintaining system reliability through active determination and selective grounding.
