Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical workers face risks of injury or death when checking for voltage inside closed electrical panels, as existing safety measures can reduce productivity and may not always be followed due to the time-consuming nature of opening panels for non-contact voltage detection.
Innovation Solution
A pass-through device with posts and indentations allows non-contact voltage detectors to be used without opening the panel, positioning wires correctly for detection, enabling safe and efficient voltage checking by aligning them with protrusions for the detector's probe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical workers open the electrical panel to check for voltage, then they can perform voltage detection, but the risk of electrical accidents increases and productivity decreases
Solution Approach 1:
The patent introduces a pass-through device as an intermediary component that allows voltage detection without direct access to the panel interior. The device includes a non-contact voltage detector positioned through the panel enclosure, enabling workers to detect voltage presence remotely while maintaining physical separation from potential hazards, thus resolving the contradiction between safety and productivity
2Reliability
If electrical workers follow safety measures and protocols, then the risk of electrical accidents is reduced, but productivity is reduced
Solution Approach 1:
The pass-through device enables the voltage detection system to serve itself by providing built-in positioning features (indentations and protrusions) that automatically align the non-contact voltage detector with the target conductors. This self-aligning mechanism eliminates the need for workers to manually position the detector or follow complex safety protocols for panel opening, thereby maintaining safety while improving productivity
3Ease of operation
If electrical workers open the electrical panel for voltage detection, then they can access the wires for testing, but time is consumed by safety procedures
Solution Approach 1:
The pass-through device is pre-installed in the panel enclosure with wires already positioned and secured to the device. The non-contact voltage detector is pre-positioned through the enclosure using protrusions that align with the wires. This preliminary setup eliminates the need for workers to spend time opening panels, positioning detectors, or following safety procedures during the actual voltage detection task

Function Achieved in This Case
Enables safe and efficient detection of voltage within closed electrical panels, reducing the need for time-consuming safety procedures and minimizing productivity loss by allowing voltage checks without opening the panel, thus enhancing worker safety and productivity.
Implementation Method 1
In a NCVD instead of direct contact with a circuit, changes in an electric field associated with the presence of an AC voltage are detected capacitively.
