Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple connecting terminals and complex mechanical connections are used, then reliable electrical connection is achieved, but production cost increases
Solution Approach 1:
The patent merges the functions of multiple connecting terminals into a single integrated connector structure. The first and second connectors are directly butted together to form a unified electrical connection path, eliminating the need for separate connecting terminals and reducing component count while maintaining reliable electrical connection.
Solution Approach 2:
The patent extracts and eliminates unnecessary connecting terminals from the traditional connector assembly. By using direct butting connection between the first and second connectors, the intermediate connecting terminals are removed, simplifying the structure and reducing production cost while preserving electrical connection reliability.
2Reliability
If multiple connecting terminals are used, then electrical connection is achieved, but signal attenuation increases
Solution Approach 1:
The patent merges the electrical connection path into a direct butting connection between connectors, eliminating intermediate connecting terminals. This streamlined connection path reduces the number of interface points where signal attenuation can occur, thereby improving signal integrity while maintaining reliable electrical connection.
Solution Approach 2:
The patent removes unnecessary connecting terminals that act as additional signal transmission interfaces. By extracting these intermediate components and using direct connector butting, the signal path is shortened and simplified, reducing cumulative signal attenuation while preserving electrical connection reliability.
3Stability of the object's composition

This unified connection structure provides stability through direct contact and geometric interlocking, eliminating the need for complex mechanical fastening mechanisms while reducing overall device complexity.
Solution Approach 2:
The patent extracts and removes complex mechanical connection components from the traditional connector assembly. By using a simplified butting connection approach, unnecessary mechanical elements are eliminated, reducing device complexity while maintaining connector stability through the direct interface between connectors.
4Reliability
If multiple connecting terminals are used, then electrical connection is achieved, but production cost increases
Solution Approach 1:
The patent merges multiple connecting terminals into a single integrated connector assembly, reducing the number of discrete components that need to be manufactured and assembled. This consolidation simplifies the production process, improves manufacturing efficiency, and maintains reliable electrical connection through the unified connector structure.
Solution Approach 2:
The patent removes unnecessary connecting terminals from the assembly, reducing component count and simplifying the production workflow. This extraction of redundant elements streamlines manufacturing operations, improves productivity, and maintains electrical connection reliability through the direct connector interface.
