Sliding Door Cable Routing With Flexible Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door systems face challenges with high costs and complexity in installing and mounting power and communication cables, as they often require integration into a hollow rigid belt, making it cumbersome for service personnel.
Innovation Solution
A sliding door assembly with a flexible cable arrangement that routes power and communication signals from the door operating assembly to electric components on the sliding door leaf, using a flexible cable member with a fixed end section attached to the door leaf to accommodate its movement, eliminating the need for complex winding solutions and reducing wear on the cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are integrated into a hollow rigid belt for driving the door leaf, then power and communication can be transmitted to components on the door leaf, but the system becomes more expensive and more difficult to install and mount
Solution Approach 1:
The cable arrangement is segmented into a fixed end section (attached to the door leaf) and a flexible portion (providing movement compensation). This segmentation allows the cable system to adapt to door movement while maintaining reliable connections, resolving the contradiction between transmission reliability and installation complexity
Solution Approach 2:
The cable arrangement transitions from a rigid integrated structure to a dynamic flexible structure. The flexible portion allows the cable to extend and compress with door movement, providing adaptability while simplifying installation compared to complex rigid belt integration
2Reliability
If a hollow rigid belt is used to route cables, then power and communication signals can be transmitted, but installation and mounting become cumbersome for service personnel
Solution Approach 1:
The cable arrangement is extracted from the complex hollow rigid belt structure and implemented as a separate flexible cable system with a fixed end section and flexible portion. This extraction simplifies installation while maintaining signal transmission reliability
Solution Approach 2:
The cable arrangement changes from a rigid structure to a flexible structure with specific extension and compression characteristics. This parameter change enables easy installation and adaptation to door movement while ensuring reliable signal transmission
3Reliability
If cables are routed from the hollow rigid belt downwards to the door blade, then connections can be established, but the system incurs high costs
Solution Approach 1:
The flexible cable arrangement replaces the expensive hollow rigid belt structure with a simpler, more cost-effective cable system. The flexible portion with fixed end section provides necessary functionality at lower manufacturing cost while maintaining connection reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the installation process, reduces costs, and minimizes wear on the cable arrangement by allowing the flexible portion to extend and compress with the door leaf's movement, ensuring reliable power and communication transmission.
Implementation Method 1
The cable member comprises a flexible portion having an end section which is fix in relation to the sliding door leaf to allow for extension of the flexible portion to compensate for the movement of said sliding door leaf

AI summary
A sliding door assembly comprises a sliding door leaf, a sliding door rail, and a door operating assembly for operating the door leaf. The door operating assembly has a drive unit to drive the door leaf along the sliding door rail. The sliding door leaf has at least one wagon member attached thereto. The wagon member is connected with the drive unit. An electric component is mounted to the sliding door leaf. A cable arrangement transfers power and/or communication signals between the door operating assembly and the electric component. The cable arrangement comprises a flexible portion with an end section that is fixed in relation to the sliding door leaf to allow the flexible portion to extend to compensate for the movement of the sliding door leaf.
