Front Panel Light-Guiding Recesses for Sharp Symbol Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require complex structures and additional support components, which are cumbersome when the front panel is large, and struggle to achieve sufficient illumination and sharp symbol definition.
Innovation Solution
The front panel itself supports the display device, with recesses for light-guiding elements that enhance light transmission and focusing, eliminating the need for separate support devices and allowing for varied light-emitting element arrangements to create distinct illuminated areas matching the symbols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate support devices are used to hold lighting elements on the device, then the lighting elements can be securely positioned, but the structure becomes complex and cumbersome especially when the front panel has considerable dimensions
Solution Approach 1:
The patent integrates the support function directly into the front panel by creating recesses in the front panel itself to hold the light-guiding elements. This eliminates the need for separate support devices and mounting brackets, combining the structural support and light guidance functions into a single integrated component, thereby reducing overall device complexity while maintaining secure positioning.
Solution Approach 2:
The front panel serves multiple functions: it acts as the visible display surface, provides structural support through integrated recesses, and guides light transmission. By making the front panel multi-functional, the patent eliminates the need for dedicated support structures, reducing the number of components while ensuring reliable positioning of lighting elements.
2Adaptability or versatility
If the front panel has considerable dimensions with display device only in part of the front panel, then the display area can be selectively positioned, but additional support components become necessary and cumbersome
Solution Approach 1:
The front panel is segmented with specific recesses only in the areas where display functionality is needed. This allows the display device to be positioned selectively on the front panel without requiring support structures across the entire panel surface. The segmented approach provides support exactly where needed, reducing unnecessary components while maintaining adaptability for different display area configurations.
3Illumination intensity
If lighting elements have considerable luminosity to ensure sufficient illumination, then the front panel can be adequately illuminated through bezels, but the structure requires more components and assembly steps to hold lighting elements
Solution Approach 1:
The patent combines the illumination function with the structural support function by integrating light-guiding elements directly into recesses in the front panel. This eliminates the need for separate mounting brackets and support structures that would be required to hold high-luminosity lighting elements, reducing assembly complexity while maintaining sufficient illumination intensity.
4Device complexity
If light-guiding elements are inserted without recesses in the front panel, then the structure is simpler, but the material thickness impairs light transmission and focusing
Solution Approach 1:
The front panel is designed with recesses only in the specific locations where light-guiding elements need to be inserted, rather than modifying the entire panel. This local modification reduces material thickness only where necessary for optimal light transmission and focusing, while maintaining the overall structural integrity and simplicity of the front panel design.

AI summary
The device has a light-conducting element (2) inserted in a recess e.g. watch dial, and a holding device (3) for a printed circuit board (4) provided on a rear surface of a front plate (1). The board has a side that is turned towards the front plate, and arranged on an arrangement of recess in the front plate or in arrangement of the light-conducting element. The holding device and the board are elastically formed such that light-conducting element arranged between light elements and the recess is pressed by the light elements in the recess and held in the recess. USE : Display device for displaying operating condition of electrical and electronic devices. ADVANTAGE : The holding device and the board are elastically formed such that light-conducting element arranged between light elements and the recess are pressed by the light elements in the recess and held in the recess, thus ensuring improved illumination of a display region on the front plate in a simple manner.
