Flexible Circuit Board Rolled Body Hinge Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently inserting a flexible circuit board with a wider width through a hinge bore, as existing methods require additional protection tubes that complicate assembly and disposal, leading to inefficiencies and waste.
Innovation Solution
A flexible circuit board with a pre-folding line is folded and wound with an extended sheet to form a rolled body, allowing it to be inserted through the hinge bore without additional protection, and the extended sheet serves as a protective wrapper and grip for reuse and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specifically provided protection tube is used to wrap around the rolled flexible circuit board, then the flexible circuit board is protected during assembly, but the assembly process becomes more complex and time-consuming, and the protection tube becomes waste after disposal
Solution Approach 1:
The extended sheet is integrated as part of the flexible circuit board structure itself, eliminating the need for separate protection tubes. The extended sheet is pre-formed on the flexible circuit board and serves both as a structural component and protective element during assembly
Solution Approach 2:
The extended sheet serves multiple functions: it provides protection during assembly, acts as a grip for disassembly operations, and can be reused for different flexible circuit boards. This multi-functionality eliminates the need for dedicated protection tubes that would become waste after single use
2Reliability
If a specifically provided protection tube is used to wrap around the rolled flexible circuit board, then the flexible circuit board is protected during assembly, but the disposal or reuse of the protection tube becomes troublesome and reduces assembly efficiency
Solution Approach 1:
The protection function is merged into the flexible circuit board structure through the extended sheet, eliminating separate protection tube handling steps and improving assembly efficiency
Solution Approach 2:
The extended sheet can be recovered and reused for protecting different flexible circuit boards during assembly, eliminating waste and reducing ongoing costs while maintaining protection effectiveness
3Area of moving object
If the flexible circuit board is made with width greater than the bore size, then the circuit board can accommodate more components and connections, but it becomes difficult to insert through the hinge bore
Solution Approach 1:
The flexible circuit board is rolled into a cylindrical shape along its length, transforming the flat wide board into a compact rolled body that can easily pass through the hinge bore while maintaining the full circuit board area for components and connections
Solution Approach 2:
The flexible circuit board is nested within the extended sheet during the rolled configuration, allowing the larger-area circuit board to be inserted through the smaller bore and then deployed to its full functional size

AI summary
Disclosed is a penetration and assembly structure for a flexible circuit board with a hinge assembly. With a pre-folding line formed on a pre-prepared flexible circuit board serving as a center line, a connection section of the flexible circuit board is folded to a terminal distribution section, and then, the connection section and an extended sheet are wound up in a direction towards the terminal distribution section to form the connection section into a rolled body with the extended sheet wrapped around the rolled body to provide an effect of protection. The rolled body is then inserted through a bore of a hinge assembly so that after the rolled body completely passes through the bore of the hinge assembly, the extension section of the flexible circuit board is located in the bore of the hinge assembly and the first end and the second end are respectively set at opposite ends of the bore of the hinge assembly. In other applications, a reinforcement plate is included to reinforce the terminal distribution section of the flexible circuit board.
