Tubular Cable Holder Assembly for Protected Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working apparatuses with tubular parts and electric cable arrangements face challenges in protecting the cables from damage and optimizing their guidance and holding during assembly and use.
Innovation Solution
A working apparatus with a rod-shaped cable holder that is inserted into the tubular part and has a cable holding arrangement to secure the electric cable arrangement, allowing for defined guidance and holding of the cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable arrangement is placed directly in the tubular part during assembly, then the assembly process becomes complex and time-consuming, but the cable protection and guidance are insufficient
Solution Approach 1:
The cable arrangement is pre-mounted on the cable holder before insertion into the tubular part. This preliminary assembly action simplifies the final installation process while ensuring proper cable positioning and protection from the outset, resolving the contradiction between assembly ease and cable protection.
Solution Approach 2:
The cable holder acts as an intermediary component between the cable arrangement and the tubular part. It provides a structured interface that guides and protects the cables while facilitating simplified assembly, thereby improving both manufacturing ease and cable reliability simultaneously.
2Device complexity
If the cable arrangement is secured without a dedicated holding structure, then the device structure becomes simpler, but the cable guidance and protection are inadequate
Solution Approach 1:
The cable holder serves as a mediator that introduces minimal structural complexity while providing essential cable guidance and protection functions. It reduces cable damage risk without significantly increasing overall device complexity.
Solution Approach 2:
The cable holder may incorporate flexible or thin-walled structures that provide cable protection while maintaining a compact and simple overall device design, balancing structural simplicity with adequate cable safeguarding.
3Productivity
If the cable arrangement is pre-mounted on the cable holder, then the assembly process is simplified, but additional components are required
Solution Approach 1:
By pre-mounting the cable arrangement on the cable holder, the assembly process is accelerated as the cable holder with attached cables can be inserted as a single unit. The productivity gain from simplified assembly outweighs the addition of the cable holder component.
Solution Approach 2:
The cable holder serves multiple functions: it holds the cable arrangement, guides cable positioning, provides mechanical protection, and facilitates assembly. This multi-functionality justifies the additional component by eliminating the need for separate assembly steps and other protective structures.

AI summary
A working apparatus has a manual operating region, a tubular part extending away from the manual operating region, and an electric cable arrangement in the tubular part. The working apparatus includes a rod-shaped cable holder, which is inserted into and held in the tubular part and has a cable holding arrangement, by which the cable arrangement is held in a pre-mounted manner on the cable holder. An assembly method secures the cable arrangement on the cable holder by the cable holding arrangement, and inserts the cable holder, with the cable arrangement held thereon, into the tubular part. The working apparatus may be a battery-operated, hand-guided garden or forestry working apparatus.
