Light Guide Plate Wiring Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of wiring for powering light sources in display devices is challenging due to the presence of light guide plates, leading to reduced work efficiency and increased stress on wiring, especially as devices become smaller.
Innovation Solution
Incorporating guide parts on the light guide plate to position and manage the wiring, ensuring it is suitably arranged and reducing interference with the light guide plate and housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the wiring is arranged at the outside of the light guide plate, then the influence of the wiring upon the luminance and chromaticity is reduced, but the work efficiency in assembly is lowered and the wiring easily projects to the outside of the housing
Solution Approach 1:
A wiring guide structure is introduced as an intermediary component between the light guide plate and the housing. This guide structure provides a designated path for the wiring to follow, allowing the wiring to be arranged outside the light guide plate (maintaining luminance quality) while being constrained within a controlled pathway (improving assembly efficiency and preventing projection outside housing).
2Volume of moving object
If the clearance between the light guide plate and the members around it is reduced to decrease device size, then the device size is reduced, but the probability of the wiring receiving stress from the peripheral members becomes higher
Solution Approach 1:
The space between the light guide plate and housing is segmented into a controlled wiring pathway and a restricted zone. The wiring guide structure divides this clearance space, creating a dedicated channel that protects the wiring from peripheral members while maintaining the overall compact device size. This segmentation allows tight spacing without transmitting stress to the wiring.
3Length of stationary object
If the wiring is arranged outside the light guide plate, then the thickness of the light source device can be reduced, but the wiring is difficult to suitably arrange due to the existence of the light guide plate
Solution Approach 1:
The wiring guide structure is pre-formed as an integrated feature of the light guide plate or housing, creating predetermined pathways for wiring arrangement before the actual wiring installation process. This preliminary structuring of the space makes wiring arrangement easier while maintaining the reduced thickness design, as workers simply need to follow the pre-defined guide paths rather than creating wiring routes from scratch.
