Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-display area is minimized to improve visibility and reduce dead space, then the display area increases, but the reliability and durability of adhesion members deteriorate
Solution Approach 1:
The support structure is divided into multiple portions (first support portion, second support portion, third support portion) with different functions. The first support portion provides adhesion to the substrate, the second support portion provides adhesion to the window, and the third support portion extends to distribute stress. This segmentation allows each portion to be optimized for its specific function, maintaining adhesion reliability even when the non-display area is minimized.
Solution Approach 2:
The adhesion member is designed with spatially varying properties: the first support portion has adhesion properties optimized for bonding to the substrate, the second support portion has adhesion properties optimized for bonding to the window, and the third support portion has extended geometry for stress distribution. This local quality variation ensures reliable adhesion in different regions despite the reduced non-display area.
2Area of stationary object
If the non-display area is minimized to enhance visibility, then the display area increases, but the bonding process reliability deteriorates
Solution Approach 1:
The support structure is pre-configured with specific geometric features (inclined surfaces, extended portions) and material properties before the bonding process. The first support portion is pre-formed with adhesion properties for the substrate, and the third support portion is pre-extended to provide stress distribution capability. This preliminary preparation ensures that the bonding process can be completed reliably even with minimal non-display area.
3Strength
If adhesion members are used to bond components, then component bonding is achieved, but the process efficiency and reliability need improvement
Solution Approach 1:
The support structure serves multiple functions simultaneously: it acts as an adhesion member for bonding the window to the substrate, provides stress distribution through its extended third support portion, and maintains structural integrity during the bonding process. This multi-functionality consolidates what would otherwise require multiple separate components and processes, improving bonding process efficiency while maintaining strong component bonding.
