Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the convergence box is designed with traditional one-to-one connection structure, then the electrical connection tightness is improved, but the volume and weight of the convergence box increase, making installation difficult
Solution Approach 1:
The convergence box is divided into multiple independent compartments, each housing a fuse carrier that can be individually accessed and replaced. This segmentation allows the box to maintain reliable electrical connections for multiple circuits while keeping each compartment compact and lightweight, resolving the contradiction between connection tightness and overall weight.
2Reliability
If the convergence box is designed with traditional structure, then the electrical connection reliability is improved, but the installation area increases, making installation and maintenance difficult
Solution Approach 1:
The fuse carriers are nested within the convergence box compartments, with each carrier containing fuse elements and connection terminals in a compact nested arrangement. This nesting structure maintains reliable electrical connections while minimizing the external dimensions and installation area of the convergence box.
3Productivity
If the convergence box is exposed to outdoors, then the current convergence function is achieved, but waterproof and anti-corrosion requirements become more stringent, increasing design complexity
Solution Approach 1:
The convergence box employs a sealed box body structure with integrated waterproof sealing elements and corrosion-resistant material coatings. This shell-based protection approach enables the device to maintain its current convergence function in outdoor environments while managing waterproof and anti-corrosion requirements through material selection and sealing design rather than complex structural modifications.
