Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If antenna branch and grounding structure are formed separately using conventional methods, then manufacturing precision can be maintained, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the antenna branch and grounding structure into a single integrated metal sheet component. This merging eliminates the need for separate formation and assembly processes, reducing manufacturing complexity while maintaining precision through unified structure formation. The metal sheet is designed to provide both antenna radiation elements and grounding paths simultaneously.
Solution Approach 2:
The metal sheet serves multiple functions: it provides antenna radiation elements, grounding structures, and electrical connections all in one component. This multi-functionality reduces the number of separate components needed and simplifies the overall manufacturing process while maintaining the required electrical and mechanical performance.
2Productivity
If separate substrate formation and electrical connections are used, then electrical reliability is ensured, but manufacturing cost and time increase
Solution Approach 1:
The patent integrates electrical connections directly into the metal sheet structure, eliminating separate connection processes. The metal sheet itself provides the electrical pathways, reducing manufacturing steps and time while ensuring reliable electrical performance through the inherent conductivity and continuity of the integrated structure.
3Ease of manufacture
If photolithography and etching steps are used for antenna formation, then manufacturing precision is achieved, but manufacturing cost and process complexity increase
Solution Approach 1:
The patent replaces complex photolithography and etching processes with a simpler mechanical forming approach using a pre-designed metal sheet. This substitution maintains the required precision for antenna branch formation while dramatically simplifying the manufacturing process and reducing costs by eliminating sophisticated semiconductor fabrication steps.
