Power Cord Retainer U-Shaped Clip for Extraction Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing power cords are often specific to particular plug designs and require specialized tools, making it difficult to securely fasten and retain power cords across varying plug sizes and shapes, and are prone to accidental disconnection due to extraction forces.
Innovation Solution
A Power Cord Retainer with a u-shaped interior midsection and outwardly extending clip that engages with both the power cord plug and the electrical enclosure, providing securement without the need for specialized tools and accommodating variations in plug design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated fasteners are used to secure the cord, then the cord retention is improved, but the adaptability to different plug designs deteriorates
Solution Approach 1:
The retainer is designed with a universal U-shaped interior midsection that can accommodate various plug shapes and sizes. The opposing side panels with outwardly extending clips provide a standardized retention mechanism that works with different cord types, making the same retainer applicable to multiple plug designs without modification.
2Reliability
If conventional attachment mechanisms are used, then the cord can be secured, but specialized tools are required for installation
Solution Approach 1:
The retainer features self-installing clips that engage with the electrical enclosure without requiring specialized tools. The opposing side panels with outwardly extending clips are designed to be manually positioned and secured, allowing technicians to install the retainer and secure cords using only basic hand operations.
3Ease of operation
If the cord is placed in accessible locations, then the ease of connection is improved, but the reliability against accidental disconnection deteriorates
Solution Approach 1:
The retainer applies preliminary retention force through its clips that engage both the cord plug and the electrical enclosure. This pre-applied securing force prevents the cord from being accidentally pulled out, while the retainer's design allows for intentional release when needed, balancing protection with accessibility.

AI summary
A Power Cord Retainer is disclosed for retaining a power cord in an electrical receptacle even when the cord is subjected to an extraction force. The retainer comprises a substantially flat rear panel having a left side, right side and top side that define a u-shaped interior midsection. Opposing side panels extend forward of the rear panel and include an outwardly extending clip having a hooked end adaptable for engagement and securement of a power cord plug in a receptacle. The u-shaped interior midsection is adaptable for engagement between an electrical enclosure exterior panel and a receptacle lip extension.
