Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluid bed or spray gun coating technologies are used, then coating protection can be achieved, but high material wastage occurs and foreign materials accumulate
Solution Approach 1:
The invention changes the physical state parameters of the coating material by using a viscous paste instead of liquid coating materials, and controls the viscosity within specific ranges (4000-10000 cP) to achieve optimal coating performance while minimizing material wastage
Solution Approach 2:
The invention extracts and removes the harmful recycling process from conventional coating systems, eliminating the need to recirculate coating material through filtration systems that generate foreign material contamination
2Reliability
If conventional coating technologies are used, then coating application is possible, but additional processing steps are required to maintain chemical and physical composition
Solution Approach 1:
The coating material is prepared in advance with optimal viscosity and chemical composition, and remains stable throughout the coating process without requiring intermediate processing steps for maintenance of its properties
Solution Approach 2:
The viscous paste coating material maintains its own chemical and physical composition stability automatically during the coating process, eliminating the need for external intervention through stirring or degassing equipment
3Measurement precision
If miniaturized design is implemented, then higher accuracy is required, but yield loss increases
Solution Approach 1:
The invention applies coating material with locally optimized viscosity characteristics that provide precise control over coating thickness and distribution, enabling accurate coating of miniaturized components while maintaining high yield rates
Solution Approach 2:
The coating process uses dynamic viscosity control of the paste material that allows adaptation to different component sizes and geometries, providing consistent coating quality across miniaturized designs
4Stability of the object's composition
If continuous stirring is applied, then sedimentation is prevented, but energy consumption increases
Solution Approach 1:
The invention fundamentally changes the viscosity parameter of the coating material to a high viscous paste state, which naturally prevents sedimentation without requiring mechanical stirring energy input
