Reflective Support Member for LCD Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid crystal display (LCD) devices face challenges in simplifying the assembly process and effectively dissipating heat generated by the light unit, as they require separate components for reflection and support, which complicates the manufacturing and thermal management.
Innovation Solution
A reflective support member with an integrally formed reflection plate and guide pin is disposed inside the bottom cover of the display apparatus, allowing for simplified assembly and enhanced heat dissipation by providing a heat-sink path for the light unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate components are used for reflection and support in the light unit, then the assembly process becomes complicated and time-consuming, but using integrated components increases structural complexity
Solution Approach 1:
The patent combines the reflection plate and guide pin into a single integrated reflective support member. This merging of previously separate components reduces the number of parts that need to be assembled, thereby improving assembly speed and productivity while maintaining the necessary structural functions for both light reflection and optical sheet support.
Solution Approach 2:
The reflective support member serves multiple functions simultaneously: it acts as a reflection plate to redirect light, provides support structure through integrated guide pins for positioning optical sheets, and enables heat dissipation. This multi-functionality reduces the overall component count and simplifies the assembly process.
2Ease of manufacture
If separate components are used for reflection and support, then manufacturing processes are more complex, but integrating them into one component increases device complexity
Solution Approach 1:
By integrating the reflection plate and guide pin into a single reflective support member, the patent reduces the number of manufacturing steps required. Instead of manufacturing and assembling multiple separate components, the integrated design allows for a single manufacturing process, thereby improving ease of manufacture despite the increased complexity of the integrated component itself.
3Temperature
If traditional light unit structure is used, then heat dissipation is insufficient, but adding dedicated heat dissipation components increases device complexity
Solution Approach 1:
The reflective support member is designed to serve multiple purposes: optical reflection, structural support through guide pins, and heat dissipation. By making the support structure itself thermally conductive and properly positioned, it functions as a heat sink without requiring additional dedicated heat dissipation components, thereby improving temperature management while avoiding increased device complexity.
