Backplate Assembly with Integrated Wiring Channel for Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs of super-large liquid crystal modules face issues with non-flatness and difficulty in wiring and assembling due to large convex portions on the backplate, which lead to warping and increased costs in manufacturing.
Innovation Solution
A backplate assembly with a peripheral reinforcing member and intermediate reinforcing members that provide a wiring channel within the peripheral reinforcing member, reducing the need for long conducting wires and simplifying the assembly process, while maintaining the strength and flatness of the backplate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If convex portions are added to the backplate to increase strength, then the backplate strength is improved, but the backplate warps and flatness deteriorates
Solution Approach 1:
The backplate is divided into a base plate and a separate reinforcing structure (frame-like structure). The reinforcing structure is attached to the periphery of the base plate, providing strength without requiring convex portions that would cause warping. This segmentation allows the reinforcing function to be separated from the flat surface requirement.
Solution Approach 2:
A frame-like reinforcing structure serves as an intermediary element between the base plate and the required strength. This intermediate structure provides the necessary mechanical strength while maintaining the flatness of the base plate surface, as it is attached to the periphery rather than requiring convex portions embedded in the plate.
2Ease of operation
If convex portions with wiring channels are provided on the backplate, then light source wires can be routed, but the number of convex portions increases and wiring becomes more complex
Solution Approach 1:
The reinforcing structure and wiring channel are merged into a single integrated component. The frame-like structure incorporates wiring channels within its configuration, eliminating the need for separate convex portions with wiring channels. This reduces the number of discrete elements while providing both structural strength and wiring functionality.
Solution Approach 2:
The frame-like reinforcing structure serves multiple functions simultaneously: it provides mechanical strength to the backplate and incorporates wiring channels for light source wire routing. This multi-functionality eliminates the need for separate convex portions dedicated to wiring, simplifying the overall structure.
3Strength
If convex portions are stamped on the backplate, then reinforcing structures are created, but manufacturing costs increase and sufficient wiring space is required
Solution Approach 1:
The backplate system is segmented into a base plate and a separate frame-like reinforcing structure. This allows the reinforcing function to be achieved through attachment rather than expensive stamping operations on the base plate itself, reducing manufacturing complexity and cost.
Solution Approach 2:
The frame-like structure acts as an intermediate reinforcing element that can be manufactured separately and attached to the backplate. This approach avoids the high cost of stamping complex convex portions directly into the backplate, as the reinforcing structure can be produced more economically and assembled in a separate step.
