Housing Unit Figure-Eight Winding for Linear Material Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for storing linear materials like cables wound in a figure eight configuration suffer from reduced storage volumetric efficiency due to overlapping intersection points, which can also lead to twisting when the material is pulled out.
Innovation Solution
A housing unit with a housing body that includes multiple winding regions in a circumferential direction, where the linear material is wound in a figure eight pattern in alternating region pairs, preventing intersection point overlap and minimizing twisting.

Engineering Contradiction Analysis
1Reliability
If the linear material is wound in a figure eight configuration for storage, then the cable is prevented from being twisted when pulled out, but the intersection points overlap at the same position which impairs storage volumetric efficiency
Solution Approach 1:
The patent applies dimensionality change by transitioning from a planar figure-eight winding to a three-dimensional winding structure. Multiple winding regions are arranged in the circumferential direction around a central axis, creating spatial separation of intersection points through radial and axial positioning. This 3D arrangement maintains the twist-prevention function while eliminating the overlapping intersection problem that reduces storage efficiency.
Solution Approach 2:
The winding structure is segmented into multiple discrete winding regions (first, second, third, fourth regions) positioned at different circumferential locations. Each region contains a portion of the figure-eight pattern, and the segments are distributed around the housing body's circumference. This segmentation separates the intersection points of different figure-eight loops in space, preventing overlap while maintaining the functional integrity of each winding segment.
2Volume of moving object
If multiple winding regions are arranged in the circumferential direction with figure eight patterns in alternating region pairs, then storage volumetric efficiency is improved, but the complexity of the winding structure increases
Solution Approach 1:
The patent employs asymmetric positioning of winding regions and alternating direction patterns. The first and second regions form a pair with figure-eight windings in one direction, while the third and fourth regions form another pair with figure-eight windings in the opposite direction. This asymmetric, alternating arrangement optimizes space utilization by preventing intersection overlap while creating a systematic, repeatable winding pattern that manages structural complexity through regular alternation rather than random arrangement.

AI summary
A housing unit includes: a linear material; and a housing body that houses the linear material. In the housing body, winding regions in which the linear material is wound are disposed in a circumferential direction. The linear material is wound in a figure eight in a first region pair constituted by a pair of the winding regions. The linear material is wound in a figure eight in a second region pair constituted by a pair of the winding regions that are different from the winding regions constituting the first region pair.
