Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional soldering methods are used for positioning stranded wires with small cross-sections, then the process becomes complex and time-consuming, but positioning accuracy and efficiency are insufficient
Solution Approach 1:
The soldering aid is divided into functional segments: a body for positioning, a receptacle for the stranded wire, and a contact part for electrical connection. This segmentation allows each component to be optimized independently while working together to achieve both precise positioning and efficient assembly.
Solution Approach 2:
The soldering aid acts as an intermediary tool between the stranded wire and the conductor surface. It provides a standardized interface that simplifies the soldering process while ensuring accurate positioning, thereby improving both precision and productivity.
2Manufacturing precision
If multiple stranded wires are positioned individually, then positioning accuracy can be maintained, but the process time increases significantly
Solution Approach 1:
Multiple stranded wires can be positioned and soldered simultaneously using the soldering aid. The body of the soldering aid accommodates multiple wires in defined positions, allowing parallel processing that reduces total process time while maintaining individual positioning accuracy through the structured design of the receptacle and contact parts.
3Reliability
If the contact part is made larger for better electrical contact, then electrical conductivity improves, but the device complexity and space requirements increase
Solution Approach 1:
The contact part is designed with localized contact surfaces that provide sufficient electrical conductivity only where needed. The contact surfaces are positioned precisely at the interface between the stranded wire and conductor surface, ensuring reliable electrical connection without requiring the entire contact part to be large or complex.
