Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual positioning and complex initial measurement are used to achieve precise alignment of aerodynamically functional films, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-marking the positioning film with alignment markings before application. These markings are prepared in advance and guide the operator during application, eliminating the need for complex on-site measurements and reducing immobilization time while maintaining precise alignment of the aerodynamically functional film
Solution Approach 2:
The positioning film serves as an intermediary tool between the operator and the aerodynamically functional film. It provides a simplified interface with pre-printed markings that mediate the alignment process, making it faster and easier to achieve precise positioning without requiring complex measurement procedures
2Manufacturing precision
If manual positioning methods are used for attaching aerodynamically functional films, then manufacturing precision can be achieved, but device complexity increases
Solution Approach 1:
The patent extracts the complex measurement and calculation procedures from the positioning process and replaces them with a simplified positioning film that has pre-printed markings. This removes the complexity of manual measurements while preserving positioning accuracy, as the markings directly indicate the correct placement without requiring complex device operations
3Manufacturing precision
If precise alignment of aerodynamically functional films is achieved through complex initial measurement, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent uses copying by transferring pre-calculated alignment information onto the positioning film in the form of markings. Instead of performing complex measurements during operation, the alignment data is copied in advance onto the positioning film, making the actual attachment process simple and intuitive while maintaining high precision
