Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to connect communication modules, then communication reliability is improved, but wiring costs increase and design freedom is reduced
Solution Approach 1:
The patent replaces mechanical wired connections with wireless communication technology. The master and slave communication modules establish connections through wireless signals instead of physical cables, eliminating the need for complex wiring while maintaining communication functionality. This substitution resolves the contradiction by removing the mechanical connection requirement that caused wiring complexity and cost issues.
2Stability of the object's composition
If wired connections are used between modules, then stable power supply is ensured, but module placement flexibility is limited
Solution Approach 1:
The patent replaces physical wired connections with wireless communication, allowing modules to be placed anywhere within wireless range without being constrained by cable routing. The master module can communicate with multiple slave modules wirelessly, enabling flexible placement configurations while maintaining stable power supply through the vehicle's electrical system independent of communication connections.
3Area of stationary object
If multiple communication modules are deployed to extend range, then communication coverage is improved, but system complexity and cost increase
Solution Approach 1:
The patent divides the communication system into one master module and multiple slave modules, where the master module handles complex processing and the slave modules extend coverage area. This segmentation allows the system to achieve extended communication range through multiple nodes while keeping each individual module relatively simple, with the master module coordinating the network to manage overall system complexity.
Solution Approach 2:
The master communication module is designed to perform multiple functions including managing multiple slave modules, handling complex communication protocols, and coordinating network operations. This multi-functionality consolidates complexity into a single module rather than distributing it across all modules, reducing overall system complexity while maintaining extended coverage capability through the slave modules.
