Vehicle Display Inside Mirror Tilting Lever Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inside mirrors with display units suffer from dual image issues due to aligned positioning of the display and mirror, making it difficult to ensure a clear rearward view, and lack efficient ON/OFF control for the display.
Innovation Solution
A display inside mirror with a tilting lever and integrated switch unit that allows independent tilting of the mirror and ON/OFF control of the display unit, using a conductive portion between upper and lower clips to apply power to the display unit, enabling simultaneous tilting and power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display unit and mirror are aligned in the opening, then the display unit can be positioned correctly, but a dual image occurs making it difficult to ensure a clear rearward view
Solution Approach 1:
The patent introduces a tilting mechanism that adds a rotational dimension to the mirror assembly. The mirror can now tilt relative to the display unit, allowing optical separation in the vertical dimension while maintaining horizontal alignment. This resolves the dual image problem by adjusting the mirror angle to eliminate parasitic reflections while keeping the display properly positioned.
2Ease of operation
If a separate control mechanism is added for ON/OFF control of the display unit, then efficient control is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the display control function with the existing tilting lever mechanism. The switch unit is integrated into the tilting lever assembly, allowing the same mechanical structure to serve both tilting and display control functions. This reduces overall device complexity while maintaining ease of operation.
Solution Approach 2:
The tilting lever is designed with multi-functionality: it can tilt the mirror assembly and simultaneously control the power supply to the display unit through the integrated switch unit. This universal design eliminates the need for separate control mechanisms, reducing complexity while improving ease of operation.
3Device complexity
If the switch unit is integrated into the tilting lever, then the device complexity is reduced, but the reliability of electrical connection may be compromised
Solution Approach 1:
The switch unit is segmented into distinct electrical contact elements within the tilting lever assembly. This segmentation allows for reliable electrical connections through dedicated contact points while maintaining the integrated mechanical structure. The electrical components are separately positioned to ensure stable connectivity.

AI summary
A display inside mirror includes a housing configured to be secured to a windshield glass, the housing having an opening formed therein, a mirror part disposed in the opening, a display unit disposed so as to face the mirror part, a control unit disposed adjacent to the display unit so as to control the transmission of a display image, a tilting lever disposed at one end of the housing so as to tilt the mirror part, and a switch unit disposed at the tilting lever so as to allow the power from the control unit to be selectively applied to the display unit.
