Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If male and female radio frequency terminals are used for connection, then connection reliability is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent merges the male and female radio frequency terminals into a single integrated connector structure. The inner conductor unit is directly connected to the outer conductor unit, eliminating the need for separate male and female terminal components. This integration reduces the number of parts while maintaining reliable electrical connection for microwave signal transmission.
Solution Approach 2:
The integrated connector structure serves multiple functions: it provides both the male and female terminal connection capabilities simultaneously, enables microwave signal transmission, and provides mechanical mounting support. This multi-functionality reduces overall device complexity while maintaining connection reliability.
2Ease of operation
If male and female radio frequency terminals are used, then connection is achieved, but assembly time increases
Solution Approach 1:
By combining the male and female terminals into one integrated unit, the assembly process requires fewer steps. The inner conductor unit is directly mounted within the outer conductor unit, eliminating the need for separate assembly operations for male and female terminals, thus reducing assembly time.
Solution Approach 2:
The connector is segmented into functional units (inner conductor unit and outer conductor unit) that can be manufactured separately but assembled quickly. This segmentation allows for modular manufacturing while maintaining simple assembly procedures, reducing overall assembly time.
3Adaptability or versatility
If two types of radio frequency terminals are used, then connection flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the functions of two different terminal types into a single integrated connector design. This reduces the number of unique parts that need to be manufactured, inventoried, and assembled, thereby lowering manufacturing costs while maintaining connection flexibility through the integrated design.
Solution Approach 2:
The integrated connector provides universal connection capability by incorporating both male and female terminal features in one structure. This multi-functionality eliminates the need for separate male and female terminal production lines, reducing manufacturing complexity and cost while maintaining adaptability.
4Adaptability or versatility
If separate male and female terminals are used, then connection options are increased, but insertion loss increases
Solution Approach 1:
By merging the male and female terminals into a single integrated structure with direct contact between inner and outer conductors, the patent minimizes the number of interfaces and connection points. This reduces signal reflection and insertion loss while maintaining connection versatility through the integrated design.
Solution Approach 2:
The patent extracts and eliminates the intermediate connection interface between male and female terminals. By directly connecting the inner conductor unit to the outer conductor unit without separate terminal interfaces, signal transmission is optimized, reducing insertion loss while maintaining connection options.
