Plastic Cord Retainer for Server Power Cords
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power-cord retainers are cumbersome to install and costly to manufacture, often failing to prevent power cords from disconnecting during server maintenance, which can lead to operational failures or damage.
Innovation Solution
A cord retainer with a hook, connection, and clamp portion, made from plastic materials, designed to be easily mounted on electronic modules, featuring a tubular structure for the hook and a plate structure for the clamp, allowing for secure attachment and retention of the power cord without complex assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power-cord retainers are used, then the power cord can be retained, but the installation becomes cumbersome and manufacturing cost increases
Solution Approach 1:
The retainer is divided into three functional segments: a hook portion for attaching to the handle, a connection portion for linking the hook and clamp, and a clamp portion for securing the power cord. This segmentation allows each part to perform its specific function efficiently while simplifying the overall installation process.
Solution Approach 2:
The hook portion, connection portion, and clamp portion are integrated into a single unified retainer structure that can be installed as one component. This merging eliminates the need for multiple separate parts and complex assembly procedures, thereby reducing installation complexity while maintaining reliable power cord retention.
2Reliability
If conventional power-cord retainers are used, then the power cord can be retained, but the manufacturing cost increases
Solution Approach 1:
The retainer is manufactured as a single integrated component combining the hook, connection, and clamp portions. This merging reduces the number of parts that need to be produced, stored, and assembled, thereby lowering manufacturing costs while ensuring reliable power cord retention through the coordinated design of all three portions.
Solution Approach 2:
The retainer utilizes elastic deformation of the clamp portion to achieve secure power cord retention without requiring additional fastening mechanisms or complex adjustment procedures. By changing the physical state through elastic deformation, the design simplifies manufacturing while maintaining reliability.
3Ease of operation
If the retainer structure is simplified for easy installation, then installation becomes easier, but the retention reliability may decrease

AI summary
A cord retainer is configured to be detachably disposed on an electronic device. The cord retainer includes a hook portion, a connection portion, and a clamp portion. The hook portion is configured to be fastened to the handle of the electronic device. The hook portion may be a tubular structure that extends along an extension direction. The connection portion is connected to the hook portion. The clamp portion is connected to the connection portion, and is configured to retain a cord attached on the electronic device. The clamp portion may be a plate structure that extends along an extension plane that is parallel to the extension direction.
