Honeycomb Core Display Fixing Member Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in securely fixing circuits, particularly when using a honeycomb core structure, as the thin plate members coupled to the honeycomb core restrict effective circuit attachment and heat dissipation.
Innovation Solution
A display apparatus design that incorporates a honeycomb core between upper and lower metal skins, with a fixing member extending through both skins and a filler material to enhance coupling force, and optionally features a flange on the fixing member or thread coupling for increased bonding and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thin plate members are coupled to opposite sides of the honeycomb core, then the structure provides reinforcement and heat dissipation function, but circuit fixing becomes restricted and difficult
Solution Approach 1:
The thin plate members are segmented into upper and lower skins that are coupled to opposite sides of the honeycomb core, creating distinct attachment surfaces. This segmentation allows the fixing member to extend through both skins and anchor into the honeycomb core, solving the circuit fixing difficulty while maintaining structural reinforcement.
Solution Approach 2:
The fixing member acts as an intermediary element that extends through both thin plate members and anchors into the honeycomb core. This intermediary structure enables circuit attachment to the honeycomb core while maintaining the reinforcement function of the thin plate members.
2Volume of moving object
If thin plate members are used coupled to the honeycomb core, then the structure remains compact, but coupling force between components is insufficient
Solution Approach 1:
The fixing member extends in the thickness dimension through both thin plate members to anchor into the honeycomb core. This dimensional extension provides additional anchoring points and increases coupling force without increasing the overall volume or compactness of the structure.
Solution Approach 2:
The structure combines thin plate members with the honeycomb core to create a composite structure. The fixing member integrates with both materials, extending through the plates and anchoring in the core to provide enhanced coupling force while maintaining compact dimensions.
3Reliability
If a fixing member extends through both skins to fix the circuit, then circuit attachment is improved, but assembly complexity increases
Solution Approach 1:
The upper and lower skins are pre-coupled to the honeycomb core before the fixing member is installed. This preliminary action creates a stable base structure that simplifies the subsequent assembly of the fixing member and circuit, reducing overall assembly complexity while improving attachment reliability.
