Flat Panel Detector Housing and FPC Layout for Easier Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel detectors face challenges in assembly efficiency due to the flexible circuit board needing to penetrate through the support plate, and the housing components require separate assembly, which affects overall strength and increases processing costs.
Innovation Solution
The flexible circuit board connects directly to the detection substrate without penetrating the support plate, and the main housing is formed as an integrated structure with reinforcing ribs and support pillars, enhancing stability and allowing single-sided processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible circuit board penetrates through the support plate for connection, then the electrical connection between detection substrate and driving circuit board is achieved, but the assembly efficiency is reduced and the support plate structure is weakened
Solution Approach 1:
The patent divides the connection path into two segments: the flexible circuit board connects to the detection substrate on one side of the support plate, and another flexible circuit board connects to the driving circuit board on the other side, eliminating the need to penetrate through the support plate. This segmentation maintains electrical connection reliability while avoiding structural weakening and assembly complexity.
Solution Approach 2:
The support plate serves as an intermediary structure that holds both the detection substrate and driving circuit board on its opposite sides, enabling electrical connection without penetration. The flexible circuit boards extend along the sides of the support plate to establish connections, using the support plate as a mediating platform rather than being forced through it.
2Ease of manufacture
If the housing components are assembled separately, then the manufacturing flexibility is improved, but the overall strength and processing costs are adversely affected
Solution Approach 1:
The patent merges the bottom wall and side wall into an integrated housing structure formed by single-sided processing. Reinforcing ribs are integrated into the housing structure to enhance overall strength. This merging approach maintains manufacturing efficiency through single-sided processing while achieving superior structural integrity compared to separate assembly.
Solution Approach 2:
The integrated housing structure serves multiple functions simultaneously: it provides the enclosing structure, incorporates reinforcing ribs for strength, and enables single-sided processing for manufacturing efficiency. The bottom wall and side wall integration creates a multi-functional structure that reduces processing steps while enhancing overall strength.
3Reliability
If the flexible circuit board passes through the support plate, then the connection is established, but the support plate structural integrity is compromised
Solution Approach 1:
The connection path is segmented to extend along the sides of the support plate rather than penetrating through it. This segmentation preserves the support plate's structural integrity by maintaining its continuous material structure, while still achieving reliable electrical connection through the flexible circuit boards that run along its perimeter.
