Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The positioning and retention of cable-styled devices, such as Rogowski coils, around objects is challenging due to difficulties in maintaining concentricity and accommodating various geometries, especially in complex transformer setups, which affects measurement accuracy and installation efficiency.
Innovation Solution
A positioning and retaining apparatus with a first member and a second member, featuring a hinge pin and a hook-shaped element, along with pliable insert elements that can accommodate different geometries, ensuring secure engagement and alignment, and an adjustable fastening mechanism for stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional cable mounting methods are used, then installation can be performed with simple tools, but maintaining concentricity of the conductor and Rogowski coil is difficult
Solution Approach 1:
The mounting apparatus is divided into multiple components: a first member with a first retention element, a second member with a second retention element, and pliable insert elements. This segmentation allows each component to perform a specific function while working together to achieve both ease of installation and measurement accuracy.
Solution Approach 2:
Pliable insert elements serve as intermediaries between the rigid mounting apparatus and the cable/conductor. These insert elements accommodate various cable geometries and facilitate proper positioning while maintaining concentricity, thus bridging the gap between simple mounting and precise alignment.
2Adaptability or versatility
If rigid mounting structures are used, then structural stability is achieved, but accommodating various cable geometries and transformer configurations is difficult
Solution Approach 1:
The mounting apparatus combines rigid members for overall structural stability with pliable insert elements at specific locations where cable contact occurs. This local differentiation of material properties allows the structure to be both stable and adaptable to various cable geometries.
Solution Approach 2:
The pliable insert elements can change their physical parameters (shape, flexibility) to accommodate different cable diameters and geometries. This parameter change capability allows a single mounting apparatus design to adapt to various transformer and cable configurations while maintaining stable mounting.
3Productivity
If multiple tools are required for installation, then precise positioning can be achieved, but installation time and complexity increase
Solution Approach 1:
The mounting apparatus is designed to be self-positioning through the interaction of the hinge pin, hook-shaped element, and pliable insert elements. The apparatus automatically adjusts and secures itself around the cable without requiring multiple external tools, thus achieving both ease of installation and positioning precision.
Solution Approach 2:
Multiple functions (positioning, retaining, and securing) are merged into a single integrated apparatus. The first member, second member, hinge pin, and insert elements work together as one system to accomplish both precise positioning and secure mounting in a single installation process.

AI summary
An apparatus for positioning and retaining a cable-styled device around an object includes a first member and a second member that are movable relative to each other. The first member includes a hinge element defining an opening proximate a first end of the first member, a hinge pin positioned within the opening, and a first retention element configured to receive a first section of the cable-styled device. The second member includes a generally hook-shaped element positioned at a first end of the second member and a second retention element configured to receive a second section of the cable-styled device. The hook-shaped element engages the hinge pin within the opening of the hinge element and is constructed to maintain engagement with the hinge pin when the first member and the second member are in an open position relative to each other.
