Connection Component Venting for Bubble-Free Adhesive Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to securely attach a connection component to an adherend member using a conductive member, while preventing bubbles from forming and remaining in the securing member, which can lead to reduced securing area and peeling issues due to temperature changes.
Innovation Solution
Incorporating an exhaust path in the metal terminal or securing member to evacuate bubbles generated during compression, ensuring the connection component remains firmly attached and preventing bubble retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If temperature increases in a state where bubble remains in the securing member, then bubble expands, but maintaining compressed state becomes difficult and peeling occurs
Solution Approach 1:
The invention converts the harmful effect of temperature-induced bubble expansion into a beneficial outcome by designing the securing member with expansion compensation features and adhesive layers that can accommodate volume changes without compromising the bonded joint
Solution Approach 2:
The invention applies adhesive beforehand to the terminal surface before compression, creating a cushioning layer that prevents bubble formation and ensures complete wetting of the bonding surface, thereby preventing future peeling even under temperature variations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents bubble retention, maintaining a secure attachment of the connection component even under temperature variations, thereby enhancing the reliability and durability of the connection.
Implementation Method 1
an exhaust path provided in at least one of the metal terminal and the securing member, the exhaust path being connected to or provided in at least one securing surface... the exhaust path exhausting a bubble generated in at least one of the first securing surface and the second securing surface
Implementation Method 2
the conductive member is compressed to come into contact with the metal terminal and the adherend member
Implementation Method 3
a securing member bonded to one surface of the metal terminal... the securing member securing the metal terminal and the adherend member

AI summary
A connection component can be firmly secured to an adherend member, in a state where a conductive member is compressed, to prevent a bubble from remaining in a securing member. The connection component includes a metal terminal, the conductive member provided on one surface of the metal terminal and deformable by compression, the securing member bonded to one surface of the metal terminal, and an exhaust path provided in at least one of the metal terminal and the securing member. The exhaust path is connected to or provided in at least one of a first securing surface of the securing member that is bonded to the metal terminal, and a second securing surface that is opposite to the first securing surface. The exhaust path exhausts a bubble generated in at least one of the first securing surface and the second securing surface.
