Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular light signaling devices use multiple light sources with different functions, then the functionality and versatility of the device is improved, but the number of wires in the dedicated wired network increases and electromagnetic compatibility deteriorates
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Each module is equipped with a wireless transceiver that communicates with the control unit and other modules via wireless signals, eliminating the need for extensive wired networks while maintaining full functionality of multiple light sources with different functions.
2Object-affected harmful factors
If electromagnetic shielding is implemented around cables supplying light sources, then electromagnetic interference is reduced, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent eliminates the need for electromagnetic shielding by replacing wired cable systems with wireless communication. The wireless transceivers in each module communicate without requiring physical cable connections, thereby removing the source of electromagnetic interference that would require shielding.
3Adaptability or versatility
If the number of light sources in the light bar increases, then the versatility and signaling capability are improved, but the risk of defective sources increases and repair time increases
Solution Approach 1:
The patent divides the light signaling device into independent modular units, each containing one or more light sources. When a defect occurs in one module, only that specific module needs to be replaced rather than the entire light bar. The control unit automatically detects the defective module and manages the replacement process, minimizing repair time and maintaining signaling capability with multiple light sources.
4Ease of repair
If modular light bars are used to enable module replacement, then repair time is reduced, but the complexity of electrical and mechanical connections between modules increases
Solution Approach 1:
The patent replaces complex electrical and mechanical wired connections between modules with wireless communication. Each module contains a wireless transceiver that automatically establishes communication with adjacent modules and the control unit. This eliminates the need for complex connector assemblies while enabling quick module replacement through simple mechanical attachment without wiring operations.
