Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If glass fiber is attached to ceramic plate by adhesive application method, then quality management is improved, but application range is limited and refrigerator material properties are not satisfied
Solution Approach 1:
The patent changes the fiber material parameter from glass fiber to industrial fibers (aramid fiber or carbon fiber), which fundamentally alters the material properties to meet refrigerator requirements while maintaining the adhesive application method's quality management advantages
Solution Approach 2:
The patent creates a composite material structure by bonding industrial fiber fabric to the ceramic plate surface using adhesive, combining the strength benefits of industrial fibers with the manufacturing precision of adhesive application to achieve both quality control and expanded application range
2Strength
If glass fiber is attached to ceramic plate, then strength reinforcement is achieved, but necessary properties for refrigerator application are not satisfied
Solution Approach 1:
The patent changes the fiber material from glass fiber to industrial fibers (aramid fiber or carbon fiber), which provides superior strength reinforcement while simultaneously meeting the specific property requirements for refrigerator applications such as thermal stability and structural integrity
3Productivity
If spray method is used for glass fiber attachment, then mass production is enabled, but quality management becomes difficult
Solution Approach 1:
The patent extracts the quality management problem from the spray method by switching to adhesive application method, which enables mass production through automation while maintaining superior quality control and uniformity in fiber attachment
