Interchangeable Jib Tool for Utility Task Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current jib assemblies require complex and time-consuming procedures to switch between different tasks, posing challenges for utility workers when elevated, as existing solutions lack a quick and easy method for task switching.
Innovation Solution
An interchangeable jib tool featuring a wire-handler segment and a sheave segment that can be easily switched between load-lifting and wire-handling tasks, allowing the utility worker to quickly change between tasks without tools, by positioning the sheave segment in operating and removal positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional jib tool switching procedures are used, then task switching is possible, but the procedure is complex and time-consuming
Solution Approach 1:
The jib tool is divided into separate functional segments (sheave segment and wire-handler segment) that can be independently positioned. The sheave segment can be moved between an operating position (first location) and a removal position (second location), allowing workers to switch between load-lifting and wire-handling tasks by simply repositioning the sheave segment rather than performing complex disassembly procedures
Solution Approach 2:
The sheave segment is designed with dynamic positioning capability, allowing it to be moved between fixed positions (operating and removal) along a defined path. This dynamic repositioning enables quick task switching without requiring the tool to be statically reconfigured or disassembled, reducing both time and complexity of the switching procedure
2Adaptability or versatility
If traditional jib tool switching procedures are used, then task switching is possible, but it requires additional tools and procedures
Solution Approach 1:
The sheave segment is designed to be self-repositioning along its defined path between operating and removal positions. The segment can be moved and secured without requiring external tools or complex procedures, allowing workers to perform task switching independently and quickly by simply guiding the sheave segment to the appropriate position
3Productivity
If the sheave segment is always in the operating position, then load lifting is efficient, but wire handling tasks cannot be performed
Solution Approach 1:
The jib tool is segmented into functional modules (sheave segment for load lifting and wire-handler segment for wire handling) that can be independently positioned. The sheave segment can be placed in an operating position for efficient load lifting or moved to a removal position to expose the wire-handler segment, enabling workers to perform different tasks using the same base tool without compromising efficiency in either function
Solution Approach 2:
The jib tool is designed as a multi-functional system where a single base tool can perform both load-lifting and wire-handling tasks. By repositioning the sheave segment between operating and removal positions, the tool universally serves different purposes, eliminating the need for multiple separate tools while maintaining productivity for each specific task

AI summary
A jib tool is configured to be secured to a distal end of a jib. The jib tool includes a wire-handler segment and a sheave segment. The wire-handler segment is configured to receive a wire. The sheave segment including a housing and a sheave. The sheave is configured to receive a load line. The sheave segment is configured to be placed in an operating position and a removal position, wherein the sheave is in a first location relative to the housing while the sheave segment is in the operating position, and wherein the sheave is in a second location relative to the housing while the sheave segment is in the removal position. The removal position is configured to allow a utility worker to remove the load line.
