Detachable Wire Puller Reel for Easy Pull-Wire Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire pullers require operators to carry multiple sets of wire pullers with different specifications and lengths, and replacing pull wires is cumbersome and inconvenient due to the non-disassemblable wheel frame.
Innovation Solution
A wire puller design featuring a main frame, take-up wheel, fasteners, and spring tube that allows easy disassembly and assembly of half-wheel frames for changing pull wires with different specifications and lengths, facilitated by fasteners and a free-rotating take-up wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wheel frame is integrally formed, then the structural strength is improved, but the ease of operation deteriorates because the pull wire cannot be easily replaced
Solution Approach 1:
The wheel frame is divided into two separate half-wheel frames that can be assembled and disassembled. The first half-wheel frame includes a sleeve connected to the fixing shaft, while the second half-wheel frame can be detached to allow pull wire replacement. This segmentation maintains structural integrity during use while enabling easy maintenance and wire replacement when needed.
2Adaptability or versatility
If multiple sets of wire pullers with different specifications are prepared, then the adaptability is improved, but the weight of moving object increases
Solution Approach 1:
The wire puller is designed with a universal structure that can accommodate different types and specifications of pull wires through the detachable half-wheel frame system. The standardized interface and fastening mechanism allow a single wire puller unit to serve multiple functions and adapt to various wire types, eliminating the need to carry multiple specialized tools.
3Productivity
If the wheel frame is made large in volume, then the productivity is improved by accommodating longer pull wires, but the weight of moving object increases
Solution Approach 1:
The wire puller incorporates a take-up wheel mechanism that can dynamically adjust and store pull wire of varying lengths. The reel-based system allows the device to accommodate different wire lengths without requiring a proportionally larger overall structure, maintaining portability while enabling extended wire installation capabilities for improved productivity.

Function Achieved in This Case
Enables easy and convenient replacement of pull wires with various specifications and lengths, reducing the need for multiple pullers and improving portability.
Implementation Method 1
The spring tube is passed and fixed to the fixing bracket at one end and the other end of the spring tube is provided for the other end of the pull wire being sent out or retracted

AI summary
A wire puller handle for easily changing wires includes a main frame, a take-up wheel, a plurality of fasteners, and a spring tube. The main frame includes a stand, a handle, a fixing shaft, and a fixing bracket. The take-up wheel includes a first half-wheel frame and a second half-wheel frame. A winding area is defined between the first half-wheel frame and the second half-wheel frame for accommodating a pull wire, and the take-up wheel performs free rotation by sleeving the sleeve on the fixing shaft. The plurality of fasteners are respectively fixed to the first half-wheel frame and the second half-wheel frame. The spring tube is passed and fixed to the fixing bracket at one end; the other end thereof is provided for the other end of the pull wire being sent out or retracted when the take-up wheel is in free rotation.
