Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple pushing connection method is used, then the mounting process is simplified, but the mounting security and electrical contact reliability are insufficient
Solution Approach 1:
The patent combines multiple functions into the electrical member: electrical conduction, mechanical fastening through insertion into recesses, and positioning through geometric constraints. This integration achieves both simple operation and reliable mounting without requiring separate fastening components.
Solution Approach 2:
The electrical member acts as an intermediary element that connects two elements together. It provides the electrical connection while simultaneously serving as the mechanical fastening element through its insertion into the recesses, ensuring both electrical reliability and mechanical security.
2Reliability
If traditional electrical connection devices are used, then electrical connection is achieved, but the system complexity and cost are higher than necessary
Solution Approach 1:
The patent merges the electrical conductor function with the mechanical fastener function into a single electrical member. This eliminates the need for separate connectors, fasteners, and insulation components, thereby reducing device complexity and cost while maintaining reliable electrical connection.
Solution Approach 2:
The electrical member serves multiple functions simultaneously: it conducts electricity, provides mechanical fastening through insertion into recesses, ensures positioning accuracy, and provides electrical insulation where needed. This multi-functionality reduces the overall system complexity.
3Manufacturing precision
If rigid connection portions are used, then manufacturing precision can be maintained, but backlash and tolerance issues arise between connected elements
Solution Approach 1:
The patent employs a design where the electrical member can dynamically adapt to manufacturing tolerances. The insertion of the electrical member into the recesses allows for self-adjustment, eliminating backlash while maintaining precise electrical connection without requiring perfect alignment.
4Manufacturing precision
If precise alignment of connection portions is required, then electrical contact quality is ensured, but the mounting process becomes more difficult and time-consuming
Solution Approach 1:
The connection system is designed to be self-aligning. The geometric relationship between the connection portions and the recesses automatically guides the electrical member into the correct position during insertion, ensuring precise electrical contact without requiring manual alignment operations.
Solution Approach 2:
The electrical member serves as a self-aligning intermediary that automatically finds its correct position through the geometric constraints of the connection portions and recesses. This eliminates the need for precise manual alignment while ensuring high-quality electrical contact.
