Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Birds and other animals landing on high-voltage power distribution lines can cause electrical shocks or short circuits, leading to animal fatalities and power outages, due to the lack of effective protection mechanisms for the lines and support structures.
Innovation Solution
A cover assembly comprising coupled hub members that can be slidably rotated to adjust the angle between conductor legs, providing a protective cover for insulators and conductor portions, which includes standoff members and extension arms to accommodate various conductor configurations and angles, preventing animal contact with the lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed protective cover is used for insulators, then animal contact with lines is prevented, but the cover cannot adapt to different conductor configurations and angles
Solution Approach 1:
The cover assembly incorporates rotatable hub members that allow the conductor legs to be positioned at various angles relative to each other. This dynamic adjustment capability enables the same cover structure to accommodate different conductor configurations without requiring multiple specialized covers, thus resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The cover assembly is designed with universal applicability through its adjustable hub members that can orient conductor legs at multiple angles. This multi-functional design allows a single cover type to serve multiple conductor configuration scenarios, eliminating the need for numerous specialized cover variants while maintaining protection effectiveness.
2Ease of operation
If a protective cover with fixed conductor leg angles is used, then manufacturing is simplified, but installation is difficult when conductor angles vary
Solution Approach 1:
The hub members are designed with rotational joints that allow field adjustment of conductor leg angles during installation. This dynamic feature enables installers to adapt the cover to existing conductor configurations on-site, significantly improving ease of installation without requiring complex custom-manufactured covers for each scenario.
Solution Approach 2:
The cover assembly is divided into modular components including separate hub members that can be independently adjusted. This segmentation allows for standardized manufacturing of individual modules while providing flexibility in field assembly and configuration, balancing manufacturing simplicity with installation ease.
3Adaptability or versatility
If multiple specialized covers are manufactured for different conductor configurations, then adaptability is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The cover assembly employs universal hub members with rotational capabilities that can accommodate various conductor angles and configurations. This multi-functional design consolidates what would otherwise require multiple specialized cover variants into a single adaptable product, reducing inventory complexity while maintaining broad applicability.
Solution Approach 2:
The adjustable rotational joints in the hub members provide dynamic adaptability to different conductor configurations. This dynamic feature allows a single cover design to replace multiple static designs, eliminating the need to manufacture and manage inventories of numerous specialized cover types.

AI summary
A cover assembly for an insulator and first and second conductor portions extending therefrom includes first and second coupled hub members defining a central cavity sized and configured to receive the insulator. The first hub member includes a first leg defining a first lengthwise cavity extending from the central cavity and configured to receive the first conductor portion. The second hub member includes a second leg defining a second lengthwise cavity extending from the central cavity and configured to receive the second conductor portion. The first and second hub members are configured to be slidably rotated relative to one another to selectively adjust an angle between the first and second legs.
