Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two resin layers are formed to achieve both flexibility and etching resistance, then both flexibility and etching resistance are improved, but the process complexity and manufacturing time increase
Solution Approach 1:
The patent combines the functions of flexibility and etching resistance into a single resin layer by incorporating specific additives (silane-modified polymer and metal oxide particles) into the resin composition, eliminating the need for separate functional layers while maintaining both properties
Solution Approach 2:
The patent uses a composite resin composition containing silane-modified polymer, metal oxide particles (such as silica), and specific solvents to achieve both flexibility and etching resistance in a single layer, leveraging the synergistic effects of different materials
2Reliability
If two resin layers are formed to achieve both flexibility and etching resistance, then both flexibility and etching resistance are improved, but the production efficiency decreases
Solution Approach 1:
The patent merges multiple functional requirements into a single resin layer formulation, reducing the number of coating and curing cycles from two to one, thereby improving production efficiency while maintaining etching resistance
Solution Approach 2:
The patent modifies the chemical composition parameters of the resin layer by adding silane-modified polymers and metal oxide particles, which fundamentally change the material properties to simultaneously provide flexibility and etching resistance without additional processing steps
3Productivity
If a single-layered resin layer is formed, then the process is simplified and production efficiency is improved, but it is difficult to achieve both high etching resistance and flexibility
Solution Approach 1:
The patent employs a composite resin system with silane-modified polymer base, metal oxide fillers for etching resistance, and specific solvents to achieve the desired balance of flexibility and etching resistance in a single layer
Solution Approach 2:
The patent carefully controls the composition ratios and chemical parameters of the resin components to optimize the single-layer performance, ensuring both flexibility and etching resistance are achieved through precise formulation
