Socket Wrench with Gripping Arms for Hot Line Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electricians performing hot line work face difficulties in balancing and engaging bolts or nuts at a safe distance due to the limitations of existing tools, which require maintaining a specific distance from high-voltage lines, making it challenging to efficiently attach or remove components like jumper paddles, nuts, and bolts without switching off the power lines.
Innovation Solution
A multipurpose socket wrench with an elongated tubular body and diametrically opposed holding arms that can extend beyond the distal end to grip and hold bolts, nuts, and washers, allowing for radial movement to securely position components and facilitate attachment to various tools like hot sticks, enabling efficient and safe hot line work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electricians use hot sticks to work on high-voltage lines, then safety distance is maintained, but the ability to balance and engage bolts or nuts becomes difficult
Solution Approach 1:
The socket wrench is divided into separate functional segments: a handle portion for the electrician to hold, a socket portion for receiving the bolt or nut, and a holder portion with gripping arms for securing the fastener. This segmentation allows each part to perform its specific function optimally while maintaining safety distance.
Solution Approach 2:
The holder portion with gripping arms acts as an intermediary mechanism between the electrician's tool (hot stick) and the bolt or nut. The gripping arms extend to securely hold the fastener, enabling the electrician to engage components at a safe distance without directly manipulating the bolt or nut.
2Reliability
If electricians maintain greater distance from high-voltage lines, then safety is improved, but the time and effort required to attach components increases
Solution Approach 1:
The holder portion is pre-configured with gripping arms that can immediately secure a bolt or nut when placed on it. This preliminary positioning capability eliminates the need for the electrician to manually balance and adjust the fastener at the distant working position, significantly reducing the time required for attachment.
Solution Approach 2:
The gripping arms are designed to automatically grip and secure the bolt or nut through their elastic deformation capability, without requiring manual adjustment or balancing by the electrician. The holder portion serves itself by providing self-securing functionality that reduces operational time.
3Device complexity
If traditional tools are used for hot line work, then simplicity is maintained, but versatility for different attachment components is limited
Solution Approach 1:
The socket wrench is designed with a universal holder portion that can accommodate multiple types of attachment components including bolts, nuts, and washers. The gripping arms can be positioned to securely hold any of these components, making the tool versatile for various hot line work applications while maintaining a relatively simple overall structure.

AI summary
A multipurpose socket wrench includes an elongated tubular body with an internal opening extending longitudinally from the distal end and having a hexagonal cross-section. A driver receiving opening extends longitudinally from the proximal end. Elongated holding arms are positioned in longitudinally extending grooves formed in the outer surface of the body. The arms are mounted for limited longitudinal movement between an extended position and a retracted position. An attachment component gripping feature is positioned in the portion of the arms extending beyond the distal end of the body with the arms in the extended position. The arms are further mounted for limited radial movement of the gripping features.
