High-Density Power Distribution Unit with Geometric Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution units face challenges with inadequate space for input receptacles, leading to cable interference, tangling, and disconnection issues due to the need for cables to be routed between front and rear faces, which affects cable lengths, access, and airflow.
Innovation Solution
A high-density power distribution unit with a base section and distribution walls forming a trapezoidal or geometric shape to increase surface area, incorporating mounting brackets for secure installation and cable management, allowing for more ports and reducing cable entanglement through organized bundling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If input receptacles are located in both front and rear faces of the power distribution unit, then the number of ports is increased, but cable interference and tangling occur due to routing requirements
Solution Approach 1:
The patent transitions from a conventional linear front-rear receptacle arrangement to a three-dimensional geometric configuration (trapezoidal, hexagonal, or octagonal) where ports are distributed across multiple faces and angles. This spatial reorganization allows cables to connect to ports on adjacent faces without crossing each other, eliminating tangling while maintaining high port density.
2Quantity of substance
If more receptacles are placed in the rear of the power distribution unit, then port density is increased, but space becomes inadequate and cable access becomes difficult
Solution Approach 1:
Instead of concentrating all receptacles in the rear plane, the patent distributes them across multiple three-dimensional surfaces (front face, rear face, and side faces) of a geometric shape. This allows cables to access ports from different directions, improving ease of connection while accommodating a larger total number of receptacles within the same unit volume.
Solution Approach 2:
The patent divides the receptacle array into multiple segments located on different faces of the geometric housing. Each face can be independently accessed, and cables can be routed to specific face groups without interfering with other cable connections, thereby improving accessibility while increasing total port count.
3Reliability
If cables are routed from front to rear of the power distribution unit, then connections are established, but cable lengths and airflow are affected
Solution Approach 1:
The patent enables cables to connect to ports on adjacent or opposite faces of the geometric housing without requiring long rearward routing. This three-dimensional port distribution allows cables to take shorter, more direct paths, reducing length constraints and minimizing interference with airflow patterns through the unit.
