Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional grip design is used, then the connection is reliable, but the assembly process is difficult and time-consuming
Solution Approach 1:
The grip is divided into modular components: a body with a cavity, a removable comb with notches for conductors, and a terminal block with electrical contacts. This segmentation allows each component to be optimized independently and assembled quickly through the screw-nut mechanism, reducing overall assembly time while maintaining connection reliability.
Solution Approach 2:
The comb is pre-configured with notches positioned to align with corresponding electrical contacts on the terminal block. The screw-nut assembly is pre-installed on the comb, enabling the comb to be quickly inserted into the body cavity and immediately secured by rotating the screw to engage the nut, eliminating the need for complex alignment procedures during assembly.
2Reliability
If a complex clamping mechanism is used, then the connection is secure, but the device becomes difficult to use
Solution Approach 1:
The screw-nut clamping mechanism is self-contained and self-operating. The screw threads directly into the nut that is integrally formed on the comb, creating a self-service fastening system that requires no additional tools or complex adjustment procedures. The operator simply rotates the screw to engage the nut, and the threaded mechanism automatically provides the clamping force needed to secure the comb in the body cavity.
3Manufacturing precision
If traditional assembly methods are used, then proper alignment can be achieved, but the assembly process becomes error-prone
Solution Approach 1:
The comb and terminal block feature asymmetric keying elements with specific angular orientations. The comb has a keyed portion that fits into a corresponding recess in the body, while the terminal block has a polarizer element with a specific angular position. This asymmetric geometry ensures that the components can only be assembled in the correct angular relationship, preventing misalignment and assembly errors while maintaining precise alignment of the notches with the electrical contacts.
