Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle sun visor systems face instability in power supply to the lighting device due to elongated conductive paths and complex wiring, making it difficult to turn the lighting device on and off reliably while maintaining a simplified structure.
Innovation Solution
Incorporating a magnet-based system that switches inductive switches between ON and OFF states, allowing the lighting device to be easily controlled by the position of the visor, thereby simplifying the structure and stabilizing the power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are routed from the ceiling into the visor main body to electrically connect the lighting device, then the lighting device can be powered, but the conductive path becomes elongated and power supply becomes unstable
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless power transmission system using electromagnetic induction. The ceiling component includes a transmitter that wirelessly transmits power to the lighting device in the sun visor, eliminating the need for physical wire connections and thereby resolving the contradiction between power supply stability and wiring complexity
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium to transfer power from the ceiling to the sun visor. This intermediary allows power transmission without direct physical contact, avoiding the problems associated with wire routing while maintaining reliable power delivery
2Ease of manufacture
If wires are routed through the limited portion of the vehicle sun visor coupled to the ceiling, then electrical connection is achieved, but the structure becomes complicated
Solution Approach 1:
The patent replaces the mechanical wire routing system with a wireless electromagnetic power transmission system. This substitution eliminates the need to route wires through the limited coupling portion between the visor and ceiling, thereby simplifying the overall structure and easing manufacturing assembly
Solution Approach 2:
The patent extracts the wiring system entirely from the sun visor structure by implementing wireless power transmission. This removal of the wiring component eliminates the structural complications that would otherwise arise from routing wires through the limited coupling area
3Ease of operation
If an inductive switch is incorporated to control the lighting device, then the lighting can be turned on and off, but the conductive path elongation makes power supply unstable
Solution Approach 1:
The patent replaces the mechanical inductive switch system with a wireless electromagnetic control system. The lighting device is controlled through wireless communication signals that do not require physical wire connections, thereby maintaining both ease of operation and power supply stability simultaneously

AI summary
A vehicle sun visor module includes a ceiling component, which forms at least part of a ceiling of a vehicle, and a vehicle sun visor module, which is arranged to be adjacent to the ceiling component. The vehicle sun visor includes a visor main body, which is configured to be pivotal relative to the ceiling component between a use position and a retracted position, and a mirror attached to the visor main body. The ceiling component includes a lighting device, which is configured to radiate light into a passenger compartment, and an inductive switch, which turns on the lighting device when set to an ON state and turns off the lighting device when set to an OFF state. The vehicle sun visor includes a magnet that is configured to switch the inductive switch between the ON state and the OFF state.
