Segmented Cable Spine for Signal Integrity and Assembly Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cable harnesses in computer racks face issues with signal integrity, mechanical stress, and inadequate protection from environmental and human factors, leading to inefficiencies in assembly and increased complexity in data center infrastructure.
Innovation Solution
A segmented spine system with articulating segments and conductive layers is introduced to protect and route cable harnesses, providing a robust and efficient method for cable management within data center racks, allowing for pre-assignment of routing paths and improved electromagnetic compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional soft-form cable harnesses are used, then flexibility and ease of installation are improved, but signal integrity and mechanical stress resistance deteriorate
Solution Approach 1:
The cable harness is divided into multiple segments with rigid portions and flexible portions. The rigid segments provide structural support and signal integrity, while the flexible segments allow for installation flexibility and movement accommodation.
Solution Approach 2:
The cable harness combines different materials with complementary properties - rigid materials (such as rigid foam or plastic) for structural segments to maintain signal integrity, and flexible materials for connection segments to enable easy installation and movement.
2Ease of manufacture
If traditional protective devices for cable harnesses are used, then basic protection is provided, but electromagnetic compatibility and build efficiency are insufficient
Solution Approach 1:
The protective device is divided into multiple segments that can be independently manufactured and then assembled, improving build efficiency while allowing each segment to be optimized for electromagnetic shielding properties.
Solution Approach 2:
The protective device serves multiple functions simultaneously: it provides mechanical protection for the cable harness, electromagnetic shielding through conductive layers, and structural support through rigid portions, eliminating the need for separate protective components.
3Adaptability or versatility
If cable routing paths are assigned during assembly, then flexibility is maintained, but assembly time and complexity increase
Solution Approach 1:
Cable routing paths are pre-assigned during the manufacturing stage, with routing channels and exit ports predetermined in the protective device structure. This allows cables to be installed quickly without complex on-site routing decisions, reducing assembly time while maintaining routing flexibility through the pre-designed path options.

AI summary
A spine is configured to support and protect a cable harness. The spine includes a plurality of segments arranged along an axis. Each segment includes a first and second housing parts which can be closed to form a passageway or can be opened to expose cavities within each housing part. The housing parts are mated together at adjacent ends by couplings. The housing parts form at least one opening which accepts a cable of the cable harness. A lock is engaged to lock the housing parts in a closed position.
