Vehicle Rear-View Mirror With Adjustable Angle And Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear-view mirrors for vehicles either function as simple mirrors or display backup camera images but lack the ability to adjust angles optimally for both modes, and there is no seamless control over transitioning between these modes.
Innovation Solution
A rear-view mirror design featuring a body part, a mirror part, a display part, and an input member that can be configured into different states to control the mirror's operation, allowing it to function as both a mirror and a display, with adjustable angles for optimal use in each mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear-view mirror is designed to display backup camera images, then the visibility range is improved and it can be used when the rear windshield is covered, but the reliability deteriorates when errors occur in the backup camera or lens
Solution Approach 1:
The patent applies parameter changes by transitioning the display part between different states (on/off) based on the operational status of the backup camera. When the camera or lens experiences an error, the system changes the parameter of display activation to off, thereby maintaining reliability while preserving the mirror function as a backup option.
2Adaptability or versatility
If the rear-view mirror is designed to selectively act as a mirror or display, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing the rear-view mirror to perform multiple functions: it can operate as a traditional mirror reflecting rear windshield images or as a display showing backup camera images. The mirror part and display part share the same housing and are controlled by a single input member, allowing one device to serve multiple purposes without requiring separate mirror and display units.
3Ease of operation
If different optimal angles are required for mirror mode and display mode, then the ease of operation is improved, but the device complexity increases due to additional angle adjustment mechanisms
Solution Approach 1:
The patent applies dynamics by making the body part rotatable relative to the housing, allowing the mirror part and display part to be tilted to different angles. The rotatable connection enables dynamic angle adjustment so that the mirror part can be oriented for optimal mirror viewing while the display part can be oriented for optimal display viewing, with each part independently adjustable to its optimal angle.
4Ease of operation
If angle adjustment and mirror-image transition are controlled individually, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the control functions into separate operations: the input member controls the angle adjustment of the body part independently, while the display control unit separately manages the on/off state of the display part based on backup camera status. This segmentation allows each function (angle adjustment and display activation) to be controlled independently through distinct control pathways.

AI summary
A rear-view mirror for a vehicle includes a body part, a mirror part, a display part, and an input member configured to control at least one of the body part or the display part, the input member configured to be selectively arranged in first, second, and third states. Based on the input member being in the first state, the body part is configured to be placed in a first position, and the display part is configured to turn on, based on the input member being in the second state, the body part is configured to be placed in a second position, and the display part is configured to turn on, and based on the input member being in the third state, the body part is configured to be placed in the second position, and the display part is configured to turn off.
