Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for pulling wire through electrical breaker boxes are not suitable for easy, portable, and cost-effective operation, as they lack efficient mechanisms for aligning and securing the wire within the conduit.
Innovation Solution
A wire puller apparatus with a pivotally joined upright shaft, pulleys, and a spud design that secures to the conduit pipe, allowing easy alignment and pulling of the wire over pulleys, enabling efficient and portable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wire pulling device is designed to be portable and easily moved between job sites, then ease of operation and adaptability are improved, but structural complexity and manufacturing precision may worsen
Solution Approach 1:
The device is divided into distinct functional segments: a portable frame structure, a pulley system with upper and lower pulleys, a spud for conduit engagement, and a wire guide. This segmentation allows each component to perform its specific function independently while maintaining overall portability and ease of assembly/disassembly between job sites.
Solution Approach 2:
The device incorporates movable and adjustable components, including the pulley system that can be positioned at different heights and angles, and the spud that can be inserted into various conduit configurations. This dynamic design enables adaptation to different job site conditions without requiring multiple specialized devices.
2Productivity
If a wire pulling device uses pulleys to align and guide the wire through the conduit, then wire alignment and pulling efficiency are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The pulley system acts as an intermediary mechanism between the wire pulling force and the conduit. The upper pulley receives the pull string or wire from the user, redirects it through the lower pulley, and guides it into the conduit bore. This intermediary system transforms manual pulling force into efficient wire insertion while maintaining relatively simple device construction.
3Reliability
If a spud design is used to secure the device to the conduit pipe, then device stability and wire alignment are improved, but manufacturing precision requirements increase
Solution Approach 1:
The spud is designed with specific geometric parameters including a curved portion that matches the circular cross-section of the conduit bore. This parameter matching allows the spud to securely engage the conduit through simple geometric compatibility rather than requiring complex fastening mechanisms or high-precision adjustable components.

AI summary
Method and apparatus for pulling electrical wire through a conduit of an electrical breaker box such as might be installed at a residential home or commercial building wherein the feed wire from a main electrical feed source would be delivered and tied into the applicable home or commercial building. The device has a generally upright standing shaft having a pivot point forming upper and lower shaft portions having a pair of pulleys mounted thereon so that the electrical wire can travel over the pulleys as it is pulled by the hands of the user. The lower shaft portion has a lower brace member thereon which is placed against an upright standing conduit pipe along with another intermediate member having a thin circular curved portion forming a spud thereon designed to fit inside the internal bore of the opening into the upright standing conduit pipe so that the device is removably secured to the upright standing conduit pipe of the electrical breaker box. The electrical wire is pulled over the pair of pulleys wherein, a first pulley is disposed on an upper end of a movable upper arm and a second pulley is disposed on a bracket spaced away from the upright standing member of the device so as to align the wire with the bore of the upright standing conduit pipe.
