Segmented Bobbin Radial Disassembly for Wire Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation of wound linear bodies, such as wire ropes or steel cords, is costly and inefficient due to the need to transport heavy and bulky bobbins back to the source after use, and existing methods struggle to remove the linear body from the bobbin without damaging the core member.
Innovation Solution
A bobbin design featuring a hollow guide tube, split drum plates with biasing mechanisms, and flanges allows for the winding of linear bodies into a cylindrical shape, enabling the bobbin to be disassembled radially, allowing the linear body to be removed and transported without the bobbin, using a detachable flange and tension coil springs to facilitate easy disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the linear body is wound on a traditional bobbin for transport, then the linear body can be transported in compact cylindrical form, but the heavy and bulky bobbin must be transported back to the source, increasing transport cost
Solution Approach 1:
The bobbin is divided into separable components: a core member and a winding drum. The winding drum can be detached from the core member, allowing the linear body to be removed and transported separately without the heavy bobbin structure, thus reducing transport energy loss
Solution Approach 2:
The invention extracts the winding drum from the bobbin assembly, enabling the linear body to be removed and transported independently. This separation eliminates the need to transport the empty bobbin back to the source, directly addressing the transport cost problem
2Ease of operation
If the linear body is removed from the bobbin together with the paper core member, then the bobbin can be emptied and sent back, but the paper core member and wire material are removed together making it difficult to transport only the linear body
Solution Approach 1:
The bobbin is segmented into distinct separable parts: the core member and the winding drum. This segmentation allows the linear body to be removed from the winding drum independently of the core member, enabling efficient transport of only the linear body without the heavy bobbin components
Solution Approach 2:
The winding drum is extracted as a separate detachable component from the core member. This extraction enables the linear body to be removed and transported separately, eliminating the need to transport the empty bobbin and improving transport efficiency
3Ease of operation
If the winding drum is made with split drum plates for easy disassembly, then the linear body can be removed smoothly, but the device complexity increases
Solution Approach 1:
The winding drum is segmented into multiple split drum plates that can be separated from each other. This segmentation enables easy disassembly for linear body removal while maintaining a relatively simple overall structure compared to fully detachable designs
Solution Approach 2:
The split drum plates are designed to be movable relative to each other, allowing the winding drum to dynamically adjust its configuration for easy disassembly and reassembly, facilitating smooth linear body removal without requiring complex detachment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables the efficient and cost-effective transportation of only the linear body in a cylindrical form, eliminating the need for transporting the bobbin and reducing waste, while maintaining the linear body's shape and protecting it from external damage.
Implementation Method 1
a biasing mechanism for biasing each split drum plate inwardly is provided between the inner surface of each of the plurality of split drum plates and the outer surface of the guide tube

AI summary
A linear body that may be smoothly removed from a bobbin. The bobbin includes a guide tube, a pair of flanges provided on the ends of the guide tube, and a winding drum sandwiched between the pair of flanges. One flange is removably attached to one end of the guide tube and the other flange is fixedly secured to the other end of said guide tube. The winding drum includes a plurality of split drum plates separated by a plurality of slits. A biasing mechanism for biasing each split drum plate inwardly is provided. When the detachable flange has been attached, the split drum plates are supported at both ends from the inner side thereof by supporting projections on the inner surface of each of the flanges. When the detachable flange is removed, the split drum plates move inwardly owing to the respective biasing mechanisms.
