Adjustable Cable Insertion Aid with Flexible Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion aids for cables and cable harnesses in the automotive industry are not easily adaptable to individual requirements, such as varying lengths and channel sizes, and often require multiple elements and complex attachment methods, leading to difficulties in easy insertion and removal.
Innovation Solution
An adjustable connecting element that links the tube and insertion element, allowing for customizable length adjustments and a streamlined design to prevent catching on edges or bends, featuring a positive connection and flexible materials to facilitate easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different insertion elements of different lengths are used to meet individual requirements, then adaptability to various cable harness sizes and shapes is improved, but device complexity increases due to the need to manage and attach multiple different elements
Solution Approach 1:
The insertion element is designed with adjustable length through a telescopic mechanism, allowing a single element to adapt to different cable harness lengths dynamically. This eliminates the need for multiple fixed-length elements while maintaining adaptability.
Solution Approach 2:
The connecting element serves multiple functions: it attaches the insertion element to the tube, allows length adjustment, and provides a streamlined profile. This multi-functional design reduces the number of separate components needed, simplifying the overall system.
2Stability of the object's composition
If a rigid connection is used between the tube and insertion element, then structural stability is improved, but ease of operation deteriorates due to difficulty in insertion and removal
Solution Approach 1:
The connection between the tube and insertion element uses a dynamic fastening mechanism that allows easy attachment and detachment while maintaining structural stability during use. This enables the connection to transition between a stable state during operation and an easily separable state for removal.
3Ease of operation
If the insertion element has a streamlined design to prevent catching on edges, then ease of operation is improved, but manufacturing precision requirements increase to maintain the streamlined shape
Solution Approach 1:
The insertion element features a rounded, curved profile instead of sharp edges or angular shapes. This streamlined curvature allows smooth passage through cable channels and around bends, preventing catching while being manufacturable with standard tolerances.

AI summary
The insertion tool has a tube (1) made of textile material, which is connected with an elongated and elastically bendable insertion portion (8). A connecting element (5) is provided for directly or indirectly attaching the insertion portion to the tube. A fixture is arranged in such a way that the insertion length of the end of the insertion portion opposite to the connecting element at the end of tube, is adjusted. A belt (3) is positively connected to the connecting element.
