Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the flexible display module is exposed during assembly, then the assembly process is simple and fast, but foreign substances can damage the flexible display
Solution Approach 1:
A protective film is disposed on the flexible display before the assembly process begins, creating a preliminary protective barrier that prevents foreign substances from damaging the display during assembly operations
Solution Approach 2:
The protective film acts as an intermediary element between the flexible display and foreign substances in the assembly environment, allowing the display to remain exposed for assembly while the film absorbs the harmful effects of potential contaminants
2Object-affected harmful factors
If the flexible display is covered with protective layers, then damage from foreign substances is prevented, but the device complexity increases
Solution Approach 1:
A thin protective film is applied to the flexible display, providing necessary protection against foreign substances while maintaining the overall simplicity of the device structure and avoiding excessive complexity through the use of a single-layer thin film solution
Solution Approach 2:
The protective film serves as a temporary, disposable protective layer that is used during assembly and can be removed or discarded afterward, providing effective protection without permanently increasing device complexity
