Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable carriers for telescopic devices, such as chain mechanisms, have a large bending radius and increased weight with length, making them unsuitable for smaller devices and costly, while also risking cable interference and knotting that can cause short circuits.
Innovation Solution
A telescopic device with a flexible and resilient carrier member comprising interconnected sections that adjust their lengths to manage cable movement, preventing interference by forming U-shaped structures and utilizing a control module and control cable to maintain cable alignment and prevent knotting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chain mechanism cable carrier is used, then the cable is driven to fit the telescopic device, but the bending radius becomes large and weight increases
Solution Approach 1:
The cable carrier is divided into multiple track sections connected sequentially, where each section can independently manage cable routing. This segmentation allows the cable carrier to be shorter overall while maintaining effective cable management, thereby reducing weight without sacrificing reliability
Solution Approach 2:
The cable carrier employs a flexible structure with movable track sections that can dynamically adjust their configuration as the telescopic device extends and retracts. This dynamic adaptation enables the cable carrier to maintain proper cable routing throughout the motion range, achieving reliable cable management with a more compact, lighter design
2Reliability
If a chain mechanism cable carrier is used, then the cable is driven to fit the telescopic device, but the bending radius becomes large
Solution Approach 1:
By dividing the cable carrier into multiple smaller track sections, each section can be optimized to have a smaller bending radius. The segmented structure allows the cable to follow a more compact path through each section, achieving effective cable management with reduced bending radius compared to a single long chain mechanism
Solution Approach 2:
The track sections are designed with optimized curved paths that guide the cable through compact arcs. This curvature optimization allows the cable to navigate the telescopic motion with smaller bending radii, improving the suitability for smaller telescopic devices while maintaining reliable cable management
3Reliability
If the cable carrier is made longer to accommodate cable movement, then cable management is improved, but the weight increases
Solution Approach 1:
The cable carrier is segmented into multiple compact track sections that work together to manage cable movement. This segmentation allows the overall cable carrier length to be reduced while maintaining effective cable management, as each section handles a portion of the cable routing task rather than requiring one long continuous carrier
Solution Approach 2:
The cable carrier uses dynamic, movable track sections that adapt their configuration during telescopic motion. This dynamic behavior allows the cable carrier to be shorter in static length while still providing sufficient cable management capability throughout the extension and retraction cycles, effectively decoupling static length from functional performance

Function Achieved in This Case
The solution effectively prevents cable interference and knotting, reducing the risk of short circuits and damage, while allowing for compact and lightweight designs suitable for smaller telescopic devices.
Implementation Method 1
the carrier member is flexible and resilient. Each of the first section and the second section has a non-straight cross section, and the third section has a straight cross section. When the second body moves toward the first body along the first direction, the other end of the second section is forced to resiliently deform from the non-straight cross section to the straight cross section, and a resilient recovering force is stored therein.

AI summary
A carrier member includes a first section, a second section, and a third section. The first section has a first length. The second section has a second length. The first section, the third section, and the second section connect sequentially and form a U-shaped structure. The first section and the second section have curved sections. The third section has a flat section. When the second section moves relative to the first section, the first section or the second section having the curved section transform into the third section having the flat section and store a resilient recovering force, and the third section having the flat section transforms into the first section or the second section having the curved section for adjusting lengths of the first section and the second section, which prevents a cable disposed on the carrier member from interfering with other mechanism or getting knotted.
