Strip-like Fixing Parts for Display Panel Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information display apparatuses are heavy due to the use of sheet-like brackets for fixing the display panel, which also fail to firmly secure the circuit substrate, leading to inadequate weight reduction and component fixation.
Innovation Solution
The design incorporates a pair of strip-like fixing parts with branching ends that are screwed to the front case, effectively sandwiching and firmly fixing the display panel and indirectly securing the circuit substrate, reducing overall weight and enhancing component fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sheet-like brackets are used to fix the display panel, then the display panel can be firmly fixed, but the overall weight of the apparatus increases
Solution Approach 1:
The single sheet-like bracket is divided into multiple strip-like fixing parts (first and second fixing parts). Each strip-like part is further segmented into branching parts with multiple arms. This segmentation reduces the amount of material needed while maintaining fixation strength through distributed mounting points.
Solution Approach 2:
Instead of using a continuous sheet-like bracket, the invention uses discrete strip-like parts with branching structures that provide fixation only at specific locations where mounting is needed. The branching parts have arms extending in different directions to contact the display panel at multiple points, providing local quality fixation without the weight of a complete sheet.
2Strength
If conventional fixing structures are used, then the display panel can be fixed, but the circuit substrate is not firmly secured
Solution Approach 1:
The strip-like fixing parts serve multiple functions: they fix the display panel through their main body and simultaneously secure the circuit substrate through their branching parts. The branching parts with multiple arms can contact both the display panel and the circuit substrate, making the fixing structure universal for securing multiple components.
Solution Approach 2:
The branching parts act as intermediaries between the fixing structure and the circuit substrate. The arms of the branching parts extend to contact and secure the circuit substrate, providing a mediation mechanism that firmly secures the circuit substrate without requiring a separate fixing structure.
3Strength
If sheet-like brackets are used for fixing, then component fixation is achieved, but the apparatus design becomes less compact
Solution Approach 1:
The fixing structure is segmented into multiple thin strip-like parts with branching arms, which occupy less space compared to a solid sheet-like bracket. The segmented structure allows for better space utilization and a more compact overall apparatus design while maintaining fixation strength.
