Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display components are housed in individual housings with physical connections, then structural stability is maintained, but replacement and customization become difficult
Solution Approach 1:
The patent replaces mechanical electrical connections with wireless communication technology. The display component communicates with the vehicle's control system via wireless signals, eliminating physical electrical connectors. This substitution enables easy replacement and customization of display components without dealing with complex wiring harnesses and electrical connections, directly resolving the contradiction between adaptability and device complexity.
2Reliability
If display components require physical electrical connections, then power supply is reliable, but installation force and durability are compromised
Solution Approach 1:
The patent replaces mechanical electrical power connections with wireless power transmission or vehicle battery integration. The display component can be powered through wireless energy transfer or by integrating directly with the vehicle's existing power system without physical electrical connectors. This eliminates the need for complex electrical wiring during installation, reducing installation force requirements while maintaining reliable power supply through the vehicle's robust power system.

AI summary
A vehicle information display system (1) includes: a master-side instrument (10) including a first power transmission coil (11), a first signal transmission coil (12), and a first case (15); and a meter instrument (20) including a display unit (26), a second power transmission coil (21), a second signal transmission coil (22), and a second case (25). The master-side instrument (10) and the meter instrument (20) have a positional relation such that in a state in which a fitting recessed part (16) of the first case (15) and the second case (25) are fitted to each other, the first power transmission coil (11) is opposed to the second power transmission coil (21), and the first signal transmission coil (12) is opposed to the second signal transmission coil (22).
