Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-temperature annealing treatment is performed on the insulation layer after opening formation, then the insulation layer quality is improved, but the opening deforms and gets blocked
Solution Approach 1:
The patent applies a preliminary action by performing light curing on the insulation layer before the high-temperature annealing treatment. This pre-curing step creates a crosslinked structure that provides thermal stability and prevents the opening from deforming during the subsequent high-temperature annealing process, thus allowing the annealing to improve insulation layer quality without compromising opening shape
Solution Approach 2:
The patent changes the physical-chemical parameter of the insulation layer by introducing a light-curing step that creates crosslinking. This parameter change (from uncured to crosslinked state) increases the thermal resistance of the insulation layer, enabling it to withstand high-temperature annealing without deformation while still achieving the desired quality improvement
2Device complexity
If conventional manufacturing process is used for insulation layer, then the process is simple, but the opening deforms and resolution decreases
Solution Approach 1:
The patent introduces a preliminary light-curing action before the annealing treatment. This additional step, while increasing process complexity slightly, prevents opening deformation and maintains high resolution, thereby achieving improved manufacturing precision that justifies the added process step
