Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional stained glass methods are used to produce color standards, then the color standards can be produced with long-term stability, but the manufacturing precision and color consistency are poor due to various influencing factors in the glass making process
Solution Approach 1:
The patent uses digital printing to create accurate color copies on transparent substrates, replacing the traditional stained glass manufacturing process. This allows precise reproduction of master color standards through digital imaging technology, achieving high manufacturing precision without the complexities of glass chemistry and thermal processing
Solution Approach 2:
The patent replaces the chemical and thermal processes of stained glass manufacturing with a digital printing system. Instead of controlling chemical reactions of coloring agents in molten glass, the invention uses digital printers to deposit pigments or dyes onto transparent substrates, significantly simplifying the manufacturing process while improving color precision
2Reliability
If traditional stained glass color standards are used, then they can provide long-term color stability, but they lack adequate protection against ultraviolet degradation and other environmental factors
Solution Approach 1:
The patent creates a composite structure by combining the printed color layer with protective coating layers on transparent substrates. This multi-layer composite provides both the desired color properties and enhanced protection against ultraviolet degradation, scratching, and other environmental factors, improving overall reliability
Solution Approach 2:
The patent applies protective coatings to the transparent substrates before or during the printing process to provide beforehand protection against ultraviolet degradation and other harmful environmental factors. This preventive approach ensures the color standards maintain their integrity and color accuracy over time
3Manufacturing precision
If multiple glass pieces are compounded to correct color deviations, then the desired color can be achieved, but the device complexity and manufacturing steps increase
Solution Approach 1:
The patent uses digital printing to directly reproduce the desired color on a single transparent substrate, eliminating the need to compound multiple glass pieces. The digital printing process can achieve the target color in one step by precisely controlling pigment deposition, thereby reducing structural complexity while maintaining color accuracy
