Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in preventing the penetration of foreign matter and moisture due to gaps between components, which can compromise their performance and longevity.
Innovation Solution
A display apparatus design that utilizes a double-sided adhesive member to bond the second plate and cover member to the first plate at the edge portions of the display apparatus, eliminating gaps and enhancing sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double-sided adhesive member is used to bond plates at edge portions, then sealing performance and reliability are improved, but device complexity increases
Solution Approach 1:
A double-sided adhesive member is introduced as an intermediary component between the first plate, second plate, and cover member. This adhesive member bonds the plates together at their edge portions, effectively sealing the display module while preventing foreign matter and moisture penetration. The intermediary adhesive layer resolves the contradiction by providing reliable sealing without requiring complex mechanical fastening structures.
Solution Approach 2:
The bonding function and sealing function are merged into a single double-sided adhesive member. This adhesive member simultaneously performs the tasks of bonding the plates together and creating a sealed environment, thereby improving reliability while avoiding the need for separate sealing structures that would increase device complexity.
2Ease of manufacture
If plates are bonded at edge portions only, then manufacturing ease is improved, but gap formation may occur
Solution Approach 1:
The adhesive member is applied specifically at the edge portions of the plates rather than across the entire surface. This localized application approach simplifies the manufacturing process by reducing adhesive material usage and application complexity, while still effectively preventing gap formation and sealing the display module at the critical edge regions where gaps would compromise performance.
