Detachable Side Car Reel for Wire Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing electrical wires in buildings face challenges due to the size and weight of reel assemblies, which require heavy machinery, consume space, and complicate the transportation and dispensing of multiple wires of varying thicknesses, often leading to twists and kinks.
Innovation Solution
A system comprising a payoff reel and a side car reel with an adjustable reel lift mechanism, allowing for easier transport and dispensing of wire or cable, where the side car reel can be attached or detached from the main reel and raised/lowered independently to manage wire tension and prevent twisting or kinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single large reel assembly is used to transport wire, then the wire can be supplied continuously, but the reel assembly becomes too heavy and large to handle without heavy machinery
Solution Approach 1:
The invention divides the wire supply system into multiple separate reel assemblies (first reel assembly, second reel assembly, third reel assembly) instead of using one large reel. Each reel can be handled independently with lighter equipment, eliminating the need for heavy machinery while maintaining continuous wire supply through coordinated operation of multiple reels.
Solution Approach 2:
The invention transitions from a single vertical reel configuration to a multi-dimensional arrangement where multiple reels are positioned at different locations and can be fed into the conduit from different directions. This spatial distribution reduces the weight burden on any single reel while maintaining continuous wire supply capability.
2Ease of operation
If jack stands are used to support the reel assembly, then the reel can spin freely during wire pull, but the jack stands consume large floor space and are difficult to transport
Solution Approach 1:
The invention removes the jack stand support system entirely from the wire pulling apparatus. Instead of using external jack stands to support the reel and allow free spinning, the system uses the reel assemblies themselves in a horizontal configuration where the wire is pulled directly through the conduit without requiring elevated support structures.
Solution Approach 2:
Instead of supporting the reel from below with jack stands to enable vertical spinning, the invention inverts the approach by using horizontal reel assemblies that rotate in place on their axes. This inversion eliminates the need for elevated support structures and reduces floor space consumption.
3Adaptability or versatility
If multiple separate reels are used for different wires, then wires of varying thicknesses can be installed simultaneously, but the risk of twists and kinks increases
Solution Approach 1:
The invention merges multiple wire pulling operations into a single coordinated system where first, second, and third reels are operated together to pull multiple wires through the conduit simultaneously. The wires are bundled and pulled as a unit, which prevents individual wires from twisting or kinking while still allowing installation of wires with different thicknesses.
Solution Approach 2:
The invention uses a wire pulling cable as an intermediary element that coordinates the movement of multiple wires. The pulling cable is inserted through the conduit first, then the wires are attached to it and pulled through together. This intermediary mechanism ensures all wires move uniformly, preventing twists and kinks while enabling multi-wire installation.
