Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the driving circuit part is attached on the main surface of the display panel, then the electrical connection is achieved, but the bezel size increases
Solution Approach 1:
The patent moves the driving circuit part attachment location from the main surface (2D plane) to the side surface (3D spatial relocation), thereby reducing the bezel area while maintaining electrical connection through conductive parts extending to the side surface
2Area of stationary object
If the attachment area is reduced to minimize bezel, then the manufacturing cost decreases, but the attachment stability deteriorates
Solution Approach 1:
The conductive protrusion is inserted into the inner conductive part, creating a nested structure where the protrusion fits within the conductive part cavity, thereby maintaining stable attachment with reduced attachment area
Solution Approach 2:
The attachment structure extends from the main surface to the side surface, utilizing the third dimension (depth/height) to maintain attachment stability while reducing the footprint area on the main surface
3Reliability
If the contact area between conductive parts is increased to improve reliability, then the attachment stability improves, but the bezel size increases
Solution Approach 1:
The electrical connection path extends from the main surface into the side surface direction, increasing the contact area through 3D spatial arrangement rather than expanding the 2D footprint on the main surface
