Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing current draining post constructions for electric wiring are cumbersome, requiring clean and well-lit environments for resin coating, long curing times, and access to the cable, making in-situ wiring difficult, especially when the cable is short, and they have many components and interrupt the power supply.
Innovation Solution
A current draining post construction with a post body and cable pressing elements, featuring a movable centering plate and threaded components for easy assembly and simultaneous perforation of cables without resin coating, allowing quick and easy current drainage without interrupting power supply, using commercially available materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resin coating is used to protect the cable connection, then IP protection degree is improved, but the operation complexity and time required are increased
Solution Approach 1:
The patent extracts and eliminates the resin coating process from the cable connection system. Instead of coating the connection with resin material, the invention uses a mechanical pressing element that directly presses the cable strands against a contact surface, achieving both electrical connection and environmental protection without resin
Solution Approach 2:
The patent replaces the chemical process of resin coating and curing with a mechanical pressing system. The pressing element mechanically secures the cable strands and provides protection through its structural design, eliminating the need for chemical resin materials and their associated operational complexities
2Reliability
If resin coating is used to protect the cable connection, then IP protection degree is improved, but the time required for curing is increased
Solution Approach 1:
The patent extracts and eliminates the resin coating process from the cable connection system. Instead of coating the connection with resin material, the invention uses a mechanical pressing element that directly presses the cable strands against a contact surface, achieving both electrical connection and environmental protection without resin
Solution Approach 2:
The pressing element is pre-configured with the necessary structural features to provide both electrical connection and environmental protection in a single component, eliminating the need for subsequent resin coating and curing operations
3Ease of operation
If the cable is short in length, then the wiring operation is difficult or impossible, but using a longer cable increases the complexity of the system
Solution Approach 1:
The patent introduces a movable pressing element that can be positioned and adjusted along the cable length. This dynamic component allows the operator to access and perform wiring operations at any desired location along the cable, accommodating short cables without requiring additional cable length or complex routing
4Reliability
If a sealed connecting box is used to splice wires, then connection reliability is improved, but the number of component elements is increased
Solution Approach 1:
The patent merges multiple functions into a single integrated pressing element that simultaneously provides: (1) mechanical securing of cable strands, (2) electrical contact formation, and (3) environmental protection. This eliminates the need for separate components such as sealing boxes, coating materials, and additional fastening elements
Solution Approach 2:
The pressing element is designed as a universal component that performs multiple functions: it presses the cable strands for electrical connection, provides mechanical support, and creates the sealed environment necessary for reliable operation. This multi-functional design reduces the total number of components while maintaining connection reliability
