Telescoping Cable Unit for Server Rack Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data centers, the existing cable connection systems for server apparatuses face challenges in efficiently connecting electronic units mounted at the front and back faces of racks, leading to space inefficiencies and potential misalignment issues due to variations in component dimensions and assembly variations.
Innovation Solution
A cable unit comprising a telescoping casing with electromagnetic shielding properties, consisting of a first and second casing body that fit together to form a box-shaped configuration, allowing for adjustable length to accommodate variations in rack housing sections and securely connect electronic units with non-shielded cables, while reducing installation complexity and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed-length cable connection system is used, then the structure is simple and easy to manufacture, but it causes space inefficiency and misalignment issues due to variations in component dimensions
Solution Approach 1:
The cable connection system employs a telescopic structure with sliding mechanisms that allow the cable housing to dynamically adjust its length. The first and second casings can slide relative to each other along the longitudinal direction, enabling the system to adapt to varying distances between front-face and back-face electronic units while maintaining reliable electrical connections despite dimensional variations.
2Reliability
If the cable length is increased to accommodate all possible distances, then reliability is improved, but space utilization deteriorates and wiring space increases
Solution Approach 1:
The telescopic cable housing allows the system to extend to maximum length when needed for reliability, then retract to minimize space occupation during normal operation. The sliding mechanism enables dynamic adjustment between compact storage state and extended operational state, optimizing both reliability and space utilization.
Solution Approach 2:
The first and second casings are nested within each other, with one casing sliding inside the other. This nested structure allows the cable housing to compact into a small space when not in use, while still providing sufficient extension distance when connection is required, thereby reducing overall wiring space requirements.
3Adaptability or versatility
If manual adjustments are required for cable length, then adaptability is improved, but operation complexity and time increase
Solution Approach 1:
The cable connection system performs self-adjustment through its telescopic mechanism. When the electronic units are positioned, the sliding casings automatically extend or retract to the appropriate length without requiring manual intervention. The system self-adapts to the distance between connection points, eliminating the need for operators to manually adjust cable length.
Solution Approach 2:
The dynamic sliding mechanism allows the cable housing to automatically adjust its length in response to positioning forces from the electronic units. The first and second casings slide relative to each other based on the actual distance required, providing automatic adaptability without manual operation.
4Manufacturing precision
If a rigid cable housing is used, then manufacturing precision is easier to achieve, but the system cannot accommodate dimensional variations causing poor fits
Solution Approach 1:
The rigid casings maintain manufacturing precision while the sliding mechanism between the first and second casings provides the necessary adaptability. The rigid structure ensures precise connector positioning, while the telescopic capability allows the overall housing length to adjust to accommodate variations in electronic unit dimensions and positioning.

AI summary
A cable unit includes a first casing body, a second connector body, a first connector, a second casing, and a cable. The first casing body forms an open shape that includes a first main wall and a first peripheral side-wall. The second casing body forms an open shape that includes a second main wall and a second peripheral side-wall. The second casing body is fitted together with the first casing body such that the second casing body and the first casing body configure a box-shaped casing that expands and contracts along a direction in which the first main wall and the second main wall face each other. The first connector is provided to the first main wall. The second connector is provided to the second main wall. The cable is housed in the casing and connects the first connector with the second connector.
