Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adhering a flexible printed circuit substrate to a composite sheet material often result in voids forming between the adhesive member and the adhesion target, which can lead to inadequate bonding and reliability issues.
Innovation Solution
An adhering jig and method that utilize a mounting plate with aligning parts, first holes, and adjustable pins to precisely position and adhere the adhesive member to the adhesion target, using a combination of pin movement and adjusting members to exert a restoring force, ensuring minimal void formation during the bonding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple alignment method using through-holes and pins is used, then the alignment process is simple, but voids form between the adhesive member and adhesion target
Solution Approach 1:
The pin is made movable along the through-hole direction, transitioning from a fixed alignment tool to a dynamic pressing mechanism. The pin can move downward to apply pressing force during adhesion, eliminating voids while maintaining alignment simplicity.
Solution Approach 2:
The pin serves as an intermediary element that performs dual functions: alignment (through positioning) and pressing (through downward movement). This mediator transfers the adhesion force from the adhesive member to the adhesion target, ensuring void-free bonding.
2Stability of the object's composition
If the pin is fixed in position, then the alignment is stable, but the pin cannot exert pressing force to prevent void formation
Solution Approach 1:
The pin is designed to be movable along the through-hole, allowing it to transition from a stable alignment position to an active pressing position. This dynamic capability enables the pin to exert downward force on the adhesive member during adhesion.
Solution Approach 2:
The pin's function is segmented into two phases: alignment phase (where the pin remains stationary for positioning) and pressing phase (where the pin moves downward to apply force). This segmentation allows the pin to fulfill both alignment stability and pressing force requirements.
3Reliability
If a complex pressing mechanism is added to prevent voids, then bonding quality improves, but the device complexity increases
Solution Approach 1:
The pin is designed to perform multiple functions: alignment (through positioning in the through-hole) and pressing (through downward movement). This multi-functionality eliminates the need for separate alignment and pressing mechanisms, maintaining device simplicity while improving bonding quality.
Solution Approach 2:
The alignment and pressing functions are merged into a single pin element. The pin combines the positioning capability (for alignment) with the pressing capability (for void prevention), creating a unified tool that simplifies the overall device structure.
