Electrical Plug Securement System with Movable Extension Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical plugs often unintentionally disconnect during use of power tools and outdoor equipment, posing safety risks due to the difficulty in adjusting existing plug securing mechanisms to ensure a secure connection.
Innovation Solution
A securement system comprising a base with a locking assembly, extension bars, and a clamp with a moveable and fixed half, allowing for adjustable engagement and disengagement of connectors, ensuring a secure connection even under significant force, and accommodating various plug sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a base cylinder and cord clamp are used to secure plugs, then the connection strength is improved, but the ease of operation deteriorates due to difficulty in adjusting to correct distance
Solution Approach 1:
The extension bar is made movable rather than fixed, allowing it to slide within the base cylinder. This dynamic adjustment capability enables users to position the clamp at the correct distance for different plug sizes while maintaining a secure connection. The extension bar can be positioned at multiple locations along the base cylinder to accommodate varying plug dimensions.
Solution Approach 2:
The securing device is divided into separate functional components: a base cylinder that attaches to one cord, a movable extension bar that spans the gap, and a clamp that secures the second cord. This segmentation allows each component to be optimized independently and facilitates easier adjustment of the extension bar position to achieve proper spacing.
2Adaptability or versatility
If a fixed extension bar is used to connect base cylinder and clamp, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The extension bar is designed to move freely within the base cylinder along a guided path, allowing dynamic adjustment of its position. This enables the device to adapt to different plug sizes and distances without requiring multiple fixed-length bars or complex adjustment mechanisms. The movable design provides versatility while maintaining relatively simple construction.

AI summary
An electrical plug fastener or retention mechanism comprising a system of binding or securing electrical plugs or other connectors to avoid unintentional or accidental disconnection. The retention mechanism comprises a base for connecting to a first cord and a clamp for connecting to a second cord. The clamp and base may be connected via at least one extension bar. The base may be two separate halves with means for connecting to one of the power cords and the clamp may comprise a fixed half and a moveable half enabled to lock to the fixed half.
