Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wildlife guard assemblies for line post insulators are often expensive, difficult to install, require de-energization of lines, and fail to remain in the desired location, posing electrocution hazards and causing power outages.
Innovation Solution
A wildlife guard assembly comprising two cover sections hinged for movement between open and closed positions, a biasing member to maintain the closed position, and a toggle action lever mechanism that allows for easy installation on energized line post insulators using a lineman hotstick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wildlife guard assemblies are used, then wildlife protection is provided, but installation requires de-energization of lines and is difficult to perform
Solution Approach 1:
The assembly uses a self-latching mechanism with spring-loaded arms that automatically engage with the insulator body when the assembly is placed over it. The springs provide automatic biasing to secure the guard in position without requiring additional fastening operations, enabling installation on energized lines using only a hot stick for placement.
Solution Approach 2:
The wildlife guard assembly is divided into multiple independent components: a body section, a cap section, and spring-loaded arms. This segmentation allows the assembly to be opened for easy placement over the insulator and then automatically close and latch around the insulator, simplifying the installation process while maintaining secure attachment.
2Ease of manufacture
If prior art wildlife guards are used, then wildlife protection is provided, but they are expensive to manufacture and install
Solution Approach 1:
The wildlife guard assembly utilizes a molded insulating housing with integrated spring mechanisms, eliminating the need for separate fasteners, adhesives, or complex assembly steps. The integrated design reduces part count and manufacturing complexity while maintaining structural integrity and protection effectiveness.
3Object-affected harmful factors
If wildlife guards are installed on line post insulators, then wildlife electrocution hazards are reduced, but the guards may fail to remain in the desired location
Solution Approach 1:
The spring-loaded arms are biased by springs that provide continuous force to maintain the arms in a latched position against the insulator body. This spring force counteracts any forces that might cause the guard to become dislodged, ensuring stable positioning and reliable wildlife protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly effectively captures line post insulators and electrical conductors while allowing for easy installation without de-energizing the lines, reducing installation costs and minimizing wildlife-related hazards.
Implementation Method 1
The biasing member is one or more torsion springs disposed about the hinge axis
Implementation Method 2
The cover sections are hinged for movement about a hinge axis between a closed position and an open position

AI summary
A wildlife guard assembly is provided that includes two cover sections, a biasing member, and a toggle action lever mechanism. The cover sections are hinged so that the cover sections, when in a closed position, a cavity to capture a line post insulator is defined. The biasing member normally biases the cover sections to the closed position. The lever mechanism is connected to the cover sections and has an over-center position that releasably holds the two cover sections in an open position. The lever mechanism is positioned in the cavity such that, during installation on the line post insulator, the line post insulator interacts with the lever mechanism to move the lever mechanism from the over-center position to allow the biasing member and the lever mechanism to move the cover sections to the closed position.
