Solution Overview

Problem

Existing electrical cables are limited to connecting fixed electric/electronic devices and cannot effectively connect mobile devices such as battery packs and movable charging drums in road vehicles.

Innovation Solution

An electrical cable system with rotating segments and a rolling bearing mechanism allows for the connection of movable electric/electronic devices, such as a battery pack and a charging drum, by using insulated conductor wires and a protection sheath with separable segments that enable rotation around a longitudinal axis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an electrical cable uses a continuous protection sheath, then the cable structure is simple and manufacturing is easy, but the cable cannot accommodate rotation between mobile devices

Engineering Contradiction:
Improvemobility connection capabilityVSAvoidcable structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The protection sheath is divided into multiple separable segments that can rotate relative to each other around the longitudinal axis of the cable. This segmentation allows the cable to accommodate rotational movement between mobile devices while maintaining structural integrity and electrical connectivity.

AI summary

An electrical cable for the connection of two electric/electronic devices, in particular road vehicles, is defined by at least one electrical conductor inserted in a protective sheath made of an insulating material having two sheath portions, which define, together with the segments of electrical conductor associated thereto, relative segments of electrical cable, and are separated from one another so as to enable the two segments of electrical cable to rotate with one another about a longitudinal axis of the electrical cable.
