Multicore Cable Structure for Flexible Multi-Direction Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multicore cables suffer from issues such as decreased bending durability and enhanced flexibility, and existing technologies have not addressed the need for a multicore cable that can enhance the bending durability and flexibility, and flexibility in bending directions.
Innovation Solution
A multicore cable with a holding body comprising a first tubular portion and a second tubular portion connected by a connecting portion, where the connecting portion includes a plurality of connecting pieces arranged along the longitudinal direction to interpose between the tubular portions, enhancing the cable's flexibility and bending durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plurality of power lines and a plurality of signal lines are twisted together as a single unit, then the cable structure is simplified, but the cable outer diameter becomes larger and the wires rub against each other when bent, decreasing bending durability
Solution Approach 1:
The cable is divided into two separate tubular portions: a first tubular portion holding power lines and a second tubular portion holding signal lines. These portions are connected by connecting pieces rather than being twisted together, preventing wire rubbing while maintaining structural integrity and improving bending durability.
2Ease of operation
If the plurality of power lines and the plurality of signal lines are arranged in parallel in a row, then the cable can flexibly bend in a direction perpendicular to the alignment direction, but it becomes difficult to bend in a direction parallel to the alignment direction
Solution Approach 1:
The cable structure transitions from a two-dimensional parallel arrangement to a three-dimensional configuration with tubular portions connected by connecting pieces. This allows the cable to bend flexibly in multiple directions including both perpendicular and parallel directions to the original alignment, enhancing adaptability while maintaining flexibility.
