Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional coating processes are used to form conductive material on groove faces, then the manufacturing process is simpler, but the accuracy and speed of forming grooves deteriorates
Solution Approach 1:
The patent combines the groove formation process with the conductive material application by forming the groove faces directly from conductive material in a single step, eliminating the separate coating process and achieving both high precision and manufacturing efficiency
Solution Approach 2:
The conductive material is prepared and positioned in advance as the groove faces before the filling process, ensuring precise groove formation without requiring subsequent coating operations
2Reliability
If additional coating processes are used to provide non-insulating material on groove faces, then manufacturing completeness is improved, but production speed deteriorates
Solution Approach 1:
The patent merges multiple manufacturing steps into one by forming groove faces with the required non-insulating material properties directly during the groove formation process, eliminating additional coating steps and significantly increasing production speed while maintaining completeness
3Ease of manufacture
If wider grooves are used in energy storage devices, then manufacturing is easier, but energy density deteriorates
Solution Approach 1:
The patent uses a jet of liquid or gas to form the grooves, enabling precise control of groove dimensions including very narrow widths that would be difficult to achieve with conventional mechanical methods, thus increasing energy density while maintaining manufacturing feasibility
Solution Approach 2:
The patent changes the manufacturing approach from mechanical to fluid-based (jet formation), allowing groove width to be controlled by fluid parameters rather than mechanical tool constraints, enabling narrower grooves for higher energy density
4Reliability
If complex specialist materials are used in sensor devices, then sensor performance is improved, but production cost deteriorates
Solution Approach 1:
The patent uses conductive material that serves multiple functions: forming the groove faces, providing electrical conductivity, and acting as the sensing element itself, eliminating the need for separate specialist sensing materials and reducing production cost
Solution Approach 2:
The conductive material in the groove faces serves the dual purpose of structural formation and sensing function, making the device self-sufficient and eliminating the need for additional specialist materials
