Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conductive strip extending in longitudinal direction and two remote retaining elements are used to hold conductors at a distance, then each conductor can be independently positioned and removed, but the longitudinal dimension of the junction block cannot be reduced
Solution Approach 1:
The patent merges the functions of multiple retaining elements into a single integrated retaining element with multiple contact points. This single element can simultaneously hold multiple conductors at different positions, eliminating the need for separate retaining elements for each conductor and reducing the overall longitudinal dimension of the junction block while maintaining independent conductor positioning capability
Solution Approach 2:
The retaining element is segmented into multiple functional sections along its length, with each section capable of independently engaging with a conductor. This segmentation allows different portions of the same retaining element to hold conductors at different positions, enabling compact arrangement of conductors in longitudinal direction while preserving independent positioning capability
2Reliability
If the length of the conductive strip in longitudinal direction is increased to accommodate retaining elements, then conductors can be held at distance, but the size of the terminal block increases
Solution Approach 1:
The patent transitions from a one-dimensional longitudinal arrangement to a two-dimensional or three-dimensional configuration. Conductors are arranged in multiple layers or at different heights, allowing the retaining element to engage conductors at various positions without increasing the longitudinal dimension. This dimensional change enables compact terminal block size while maintaining reliable conductor holding capability
Solution Approach 2:
The patent employs a nested arrangement where conductors are positioned in layers or nested configurations. The retaining element extends through multiple layers to engage conductors at different levels, allowing efficient use of space and reducing the overall volume of the terminal block while ensuring reliable electrical contact and mechanical holding
