Flexible Wiring Board Restricting Structure for Pull-Force Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for assembling display devices require complex processes to fix flexible wiring boards, leading to potential damage from excessive pulling forces during assembly.
Innovation Solution
A restricting device for flexible wiring boards is designed with an insertion portion that includes rear, front, and inner restricting portions, allowing the flexible wiring board to be inserted in a straightforward manner along its surface, thereby preventing excessive movement and stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a restricting device is provided in the holder to restrict excessive movement of the flexible wiring board, then the connecting portion is protected from damage, but the device complexity increases
Solution Approach 1:
The restricting device is segmented into multiple functional portions: a rear restricting portion that contacts the rear surface of the flexible wiring board, front restricting portions that contact the front surface, and inner restricting portions that contact the side surfaces. This segmentation allows each portion to independently restrict movement in specific directions, providing comprehensive protection while keeping each individual component simple in structure.
2Ease of operation
If the flexible wiring board is inserted into the holder during assembly, then the assembly process is simplified, but excessive pulling force may damage the connecting portion
Solution Approach 1:
The restricting device applies preliminary counteracting forces through its multiple restricting portions before excessive pulling force can damage the connecting portion. The rear restricting portion prevents backward movement, the front restricting portions limit forward displacement, and the inner restricting portions constrain lateral movement, collectively opposing any harmful pulling forces during the insertion process.
3Reliability
If multiple restricting portions are provided in the holder, then the flexible wiring board is securely restricted, but the manufacturing complexity increases
Solution Approach 1:
The restricting device merges multiple restricting functions into a single integrated structure within the holder. The rear restricting portion, front restricting portions, and inner restricting portions are combined as one unified component that can be manufactured and installed as a single unit, reducing the number of separate parts and simplifying the manufacturing process while maintaining comprehensive restriction functionality.

AI summary
A restricting device for a flexible wiring board includes an insertion portion into which at least both side portions of the flexible wiring board are inserted. The insertion portion includes: a rear restricting portions protruding in a thickness direction of the flexible wiring board; a front restricting portion located forward of the rear restricting portion in an insertion direction; a restricting region formed between the front restricting portion and the rear restricting portion, and an inner restricting portion located further inward than the rear restricting portion with respect to a width direction of the flexible wiring board and protruding in a direction opposite to a protruding direction of the rear restricting portion. The protruding portion passes over the rear restricting portion and is restricted from moving in a front-rear direction in the restricting region while the flexible wiring board is being inserted into the insertion portion.
