Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bonding methods for modules, such as automotive glass, require longer curing times and are less efficient in terms of accuracy and production speed, as they rely on single bonding agents with prolonged curing processes.
Innovation Solution
A module and manufacturing method utilizing two types of bonding agents with different curing times, where a first bonding agent with high bonding strength and longer curing time is complemented by a second bonding agent with lower bonding strength and shorter curing time, allowing for faster assembly and retention of the second member on the first surface without compromising accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single bonding agent with high bonding strength is used, then bonding strength is improved, but curing time increases
Solution Approach 1:
The bonding agent is divided into two distinct types: a first bonding agent with high bonding strength and long curing time, and a second bonding agent with lower bonding strength but short curing time. This segmentation allows each bonding agent to fulfill different functional requirements, resolving the contradiction between achieving high bonding strength and maintaining short curing time.
Solution Approach 2:
The invention changes the parameters of the bonding system by introducing two bonding agents with different bonding strengths and curing times. The first bonding agent provides high bonding strength with long curing time, while the second bonding agent provides quick initial bonding with short curing time, thereby resolving the time-strength trade-off.
2Productivity
If a bonding agent with short curing time is used, then productivity is improved, but bonding strength decreases
Solution Approach 1:
The bonding function is segmented between two agents: the second bonding agent enables quick production turnover with short curing time, while the first bonding agent ensures high ultimate bonding strength. This segmentation allows the system to achieve both high productivity and high bonding strength.
Solution Approach 2:
The second bonding agent performs preliminary bonding action quickly to enable rapid production, while the first bonding agent continues to cure and provide ultimate bonding strength. This preliminary action approach allows productivity to be improved without sacrificing final bonding quality.
3Device complexity
If only one bonding agent is used, then device complexity is reduced, but manufacturing precision decreases
Solution Approach 1:
The bonding system is segmented into two bonding agents with distinct properties, allowing precise control over different stages of the bonding process. This segmentation improves manufacturing precision by enabling separate optimization of initial positioning and final bonding strength.
Solution Approach 2:
By changing the parameters of the bonding system to include two agents with different curing times and bonding strengths, the invention achieves better manufacturing precision. The first bonding agent ensures accurate final bonding, while the second bonding agent enables precise initial positioning during the brief uncured state.

This approach enables faster production and shipping of modules by shortening the time before the second member is securely bonded, improving production efficiency and reliability while maintaining high bonding strength and chemical resistance.
Implementation Method 1
a first bonding agent provided in a first region on the second surface, and bonding the second member to the first surface with first bonding strength
Implementation Method 2

AI summary
A module includes a first member with a first surface, a second member with a second surface opposed to the first surface, a first bonding agent, and a second bonding agent. The first bonding agent is provided in a first region on the second surface, and bonds the second member to the first surface with first bonding strength allowing the second member to be retained on the first surface. The second bonding agent is provided in a second region on the second surface, and bonds the second member to the first surface with second bonding strength allowing the second member to be retained on the first surface. Second curing time taken before the second bonding agent exhibits the second bonding strength by curing in a predetermined atmosphere is shorter than first curing time taken before the first bonding agent exhibits the first bonding strength by curing in the predetermined atmosphere.
