Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If wired electrical connection to vehicle power supply is used, then illumination function is achieved, but installation complexity and safety concerns increase
Solution Approach 1:
The patent replaces the mechanical wired electrical connection system with a wireless power transmission system. The wireless smart mat uses wireless communication modules to receive control signals and wireless power transmission modules to receive electrical energy wirelessly from the vehicle, eliminating the need for physical wire connections between the mat and vehicle power supply, thus reducing installation complexity while maintaining illumination functionality.
Solution Approach 2:
The patent introduces wireless communication modules and wireless power transmission modules as intermediary components. These modules act as mediators between the vehicle's control system/power supply and the mat's illumination system, enabling indirect wireless communication and power transfer instead of direct wired connections, thereby simplifying installation while achieving the illumination effect.
