Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test platforms for electromagnetic interference (EMI) tests face issues with cable tangling and damage due to the rotational motion of the round stage, which compromises the reliability and safety of the testing process.
Innovation Solution
A test platform design featuring a round supporting member with wheels that can roll along a slide rail, along with a novel cable management system using hooks and brackets to prevent cable tangling, and a conductive liquid test assembly with a light-based system to ensure proper liquid levels, while maintaining power supply through multiple power sockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stage is rotated 360 degrees using wheels rolling along a rail, then the EMI test can be performed with full rotational coverage, but the cable of the power socket gets tangled and damaged
Solution Approach 1:
The patent extracts the cable management function from the rotating stage system by introducing a separate cable storage chamber and guide structure. The cable is routed through a fixed guide on the base and stored in a dedicated chamber, separating the cable management function from the rotational motion, thereby preventing tangling while maintaining full rotational coverage
Solution Approach 2:
The patent introduces an intermediary cable guide structure and storage chamber that mediates between the rotating power socket and the stationary power source. This intermediary system allows the stage to rotate freely while the cable remains organized and protected, resolving the contradiction between rotational freedom and cable integrity
2Adaptability or versatility
If multiple power sockets are mounted on the rotating stage, then power supply capability is enhanced, but cable management becomes more complex and prone to tangling
Solution Approach 1:
The patent applies universality by designing a single cable storage chamber and guide structure that serves all multiple power sockets mounted on the stage. Instead of providing separate cable management for each socket, the unified system handles all cables collectively, reducing overall complexity while maintaining enhanced power supply capability
Solution Approach 2:
The patent merges multiple cable management functions into a single integrated storage chamber and guide system. All cables from multiple power sockets are routed through the same organized pathway and stored together, simplifying the overall cable management system while supporting multiple power outlets

AI summary
A test platform for devices requiring electromagnetic interference testing includes a base, a supporting pole perpendicularly mounted on the base, a supporting member rotatably supported on the supporting pole, and a number of conductive apparatus mounted to the supporting pole. The supporting member includes a power socket. Each conductive apparatus includes a tank fitted about the supporting pole, conductive liquid received in the tank, first cables, and a second cable. Each tank defines an annular slide slot surrounding the supporting pole. First ends of the first cables are connected the power socket, second ends of the first cables are extended through the slide slots and electrically coupled to the conductive liquid. A first end of the second cable is electrically coupled to the conductive liquid, and a second end of the second cable is electrically coupled to an uninterrupted power supply.
