Sensor Property Band for Phase Identification Without Colored Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement sensors, such as Rogowski coils, require multiple colored cables to identify different phases, leading to inefficiencies in manufacturing, stocking, and user friendliness due to the need for multiple cable types.
Innovation Solution
A property band that can be mounted to a measurement sensor, indicating conductor properties through color and featuring a coupling mechanism that secures the band to the sensor housing, allowing a single cable color to be used for various sensors, simplifying mounting and reducing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple colored cables are used to identify different phases, then phase identification is achieved, but manufacturing efficiency decreases and cable stock complexity increases
Solution Approach 1:
The invention extracts the phase identification function from the cable itself and relocates it to a separate property band that can be mounted on the sensor housing. This allows the cable to remain a single color (improving manufacturing efficiency) while the property band provides the necessary phase identification information through its color or markings.
2Loss of information
If multiple colored cables are used to identify different phases, then phase identification is achieved, but cable stock complexity and environmental impact increase
Solution Approach 1:
The phase identification information is extracted from the cable and placed on a separate property band. This reduces cable stock complexity to a single color while maintaining phase identification capability through the property band's color-coding system.
Solution Approach 2:
A single multi-functional cable design is adopted, serving both electrical connection and universal compatibility purposes, while the property band provides the specific phase identification. This eliminates the need for multiple specialized cable types.
3Reliability
If a coupling mechanism is added to secure the property band, then mounting reliability is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into separate components: a coupling element on the property band and a corresponding receptacle on the sensor housing. This modular approach ensures reliable mounting while keeping each component simple and easy to manufacture.
Solution Approach 2:
The coupling mechanism is designed to be self-aligning and self-securing, where the coupling element automatically engages with the receptacle when the property band is positioned correctly, eliminating the need for complex fastening procedures or additional tools.
