Vacuum Sleeve for Electrical Plug Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug securing devices fail to reliably prevent plug uncoupling from outlets, especially under tension, leading to potential damage and safety hazards, and often require complex installation or bulky designs that deter user adoption.
Innovation Solution
The Snug Plug device, a flexible, water-resistant sleeve with nano suction material that attaches to an electrical plug and secures it to the outlet using vacuum pressure, allowing easy installation and removal while maintaining the plug in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring clips are used in outlet slots to provide resistance to insertion and withdrawal, then some resistance to plug removal is achieved, but the clips cannot prevent plug removal when the cord is under significant tension
Solution Approach 1:
The patent introduces a separate retention device that acts as an intermediary between the plug and the outlet. This device includes a clamp that engages with the plug body and a retention member that secures to the outlet faceplate, creating an additional mechanical connection path that distributes and reinforces the retention force beyond what spring clips alone can provide
Solution Approach 2:
The retention system is divided into separate functional components: a clamp portion that attaches to the plug, a retention member that secures to the outlet, and connecting elements. This segmentation allows each component to be optimized for its specific function and enables the system to handle higher tension loads through distributed force application
2Reliability
If existing plug securing devices are used to prevent plug uncoupling, then plug retention is improved, but the devices are bulky and require complex installation which deters user adoption
Solution Approach 1:
The clamp is designed to be self-installing by simply snapping onto the plug body without requiring tools or complex procedures. The retention member features a simple attachment mechanism that secures to the outlet faceplate through direct engagement, eliminating the need for screwdrivers, adhesives, or electrical work
Solution Approach 2:
The clamp utilizes a flexible, resilient material that allows it to deform during installation and then maintain a secure grip on the plug. This flexibility enables tool-free installation while maintaining reliable retention, and the thin-profile design avoids bulkiness
3Reliability
If existing plug securing devices are used to prevent plug uncoupling, then plug retention is improved, but the devices often fail to provide adequate protection under tension
Solution Approach 1:
The retention member acts as a counterbalancing anchor that opposes the pulling force applied to the cord. By securing to the outlet faceplate structure rather than relying solely on spring clip friction, it provides a rigid counterforce that balances and neutralizes cord tension loads
Solution Approach 2:
The patent combines multiple retention mechanisms into a single integrated device: the clamp's grip on the plug, the retention member's anchor to the outlet, and the geometric constraints of the plug-receptacle connection work together synergistically to provide cumulative resistance to cord tension that exceeds the sum of individual components

AI summary
A securement device for electrical plugs, effectively keeping the plug inserted into an outlet without worry of it becoming unplugged. The device is useful for securing an electrical plug to the wall faceplate of an outlet, as well as protecting the connection from debris and moisture. The device is configured as a sleeve that attaches to an electrical plug and rolls over the plug to conform to its shape. When in use, the sleeve is squeezed on either side to create a vacuum and secure the plug connection in place. To release the device, a user again squeezes the sides of the sleeve to release vacuum pressure and removes the plug from the connection. The device can resemble a suction cup, is flexible, and can fit overtop any type of electrical plug.
