Vehicle Handle Display Optics for Reflection-Free Control Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for motor vehicle handles suffer from reflections of control element edges or recesses on the display surface, which impair readability and aesthetics.
Innovation Solution
A display device with an optical body featuring a wedge-shaped section where the first and second planes intersect, incorporating a transition with chamfers or bends to deflect light away from the display surface, and a reflective coating to conceal mounting edges, preventing reflections and enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control element is embedded in the optical body, then the control element can be integrated into the display device, but reflections from the control element edges or recesses appear on the display surface, impairing readability
Solution Approach 1:
The patent introduces a wedge-shaped section that creates a transition zone between the display surface and reflective surface, deflecting light into a different spatial dimension (away from the display surface) to eliminate harmful reflections while preserving control element integration
Solution Approach 2:
The wedge-shaped transition section acts as an intermediary element between the control element recess and the display surface, intercepting and deflecting light before it can reflect onto the display surface, thus resolving the reflection problem while maintaining integration
2Loss of information
If light is coupled into the optical body at the first coupling surface, then information can be displayed on the display surface, but light may be reflected at the reflective surface back onto the display surface, creating disturbing reflections
Solution Approach 1:
The patent applies different surface properties to different regions: the display surface remains optically smooth for information display, while the wedge-shaped transition section has a specific geometry designed to deflect light away from the display surface, creating local quality differences that eliminate reflections
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively minimizes reflections, improves readability, and maintains an aesthetically pleasing appearance by deflecting light away from the display surface and concealing mounting edges, thereby enhancing the overall display quality.
Implementation Method 1
the edges of a recess for embedding the control element, or the recess or the control element itself, may be reflected onto a display surface formed by the optical body
Implementation Method 2
at least a portion of the light can be deflected away from the display surface and/or the first plane at the transition
