Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical distribution boxes often lack sufficient connections, are prone to technical failures due to lack of strain relief for branch conductors, and are too tall for narrow installations, making them unsuitable for many industrial applications.
Innovation Solution
A distributor housing with S-shaped conductor guides, insulation displacement contacts, and branch contacts that allow for branching of multi-core cables without cutting, featuring a contact plate with embedded connection and branch contacts for secure electrical connections, and cable glands for strain relief, enabling space-saving and reliable energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional distribution boxes are used to provide multiple connections, then the number of connections increases, but the height of the device increases making it unsuitable for narrow installation spaces
Solution Approach 1:
The patent transitions from a traditional vertical stacking arrangement to a three-dimensional spatial configuration where connection elements are distributed across multiple levels and directions. The S-shaped guides and multi-level contact plate arrangement utilize horizontal and diagonal spaces, transforming the problem from a one-dimensional height constraint to a multi-dimensional space utilization solution.
Solution Approach 2:
The patent implements a nested structure where the contact plate with multiple contact elements is embedded within the housing, and the S-shaped guides are integrated into the same space. The branch conductors are routed through the housing structure itself, nesting multiple functional elements within a compact volume to minimize external dimensions.
2Ease of manufacture
If branch contacts are provided without strain relief, then the installation is simpler, but the reliability decreases due to potential technical failures in harsh environments
Solution Approach 1:
The patent incorporates strain relief mechanisms at the cable entry points and along the conductor routing paths before the conductors reach the connection points. This preventive measure absorbs mechanical stresses and prevents failure at the vulnerable connection interfaces, ensuring reliability without complicating the basic connection function.
3Length of stationary object
If the distribution housing is made compact for narrow installations, then the installation space requirement decreases, but the number of available connections is reduced
Solution Approach 1:
The patent divides the connection system into multiple independent contact elements arranged on the contact plate, each accessible through separate openings in the housing. This segmentation allows multiple connections to be distributed across the compact housing surface area, maintaining high connection capacity within a small volume.
Solution Approach 2:
The patent utilizes multi-level contact arrangements where contact elements are positioned at different heights and angles within the housing. The S-shaped guides route conductors through three-dimensional paths, effectively packing more connections into a smaller footprint by utilizing vertical and angular dimensions rather than only horizontal spacing.
