Locking Plug Adapter to Prevent Accidental Outlet Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug and outlet solutions are either impractical, bulky, or ineffective in preventing unintentional removal or insertion, often requiring modifications or tools, and can lead to electrical hazards due to partial disconnection or exposure of prongs.
Innovation Solution
A universal adapter or locking receptacle that securely locks electrical plugs to power outlets without modification, using a mechanism with high friction forces and anchoring mechanisms to prevent accidental removal and insertion, applicable to various plug and outlet types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical outlets are made accessible without restrictions, then ease of operation is improved, but safety hazards increase due to potential misuse by children and unauthorized persons
Solution Approach 1:
A locking device acts as an intermediary between the outlet and users. The device includes a lockable plug that can be secured with a key or combination mechanism, allowing authorized access while preventing unauthorized use by children or others who should not access electrical outlets.
Solution Approach 2:
The locking system segments access control by separating the outlet into two states: locked (inaccessible) and unlocked (accessible). The plug contains a separate locking mechanism that can be engaged or disengaged independently, allowing control over when the outlet is accessible without affecting the outlet's fundamental function.
2Object-affected harmful factors
If locking mechanisms are added to electrical outlets, then safety is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-contained within the plug itself, rather than requiring modification of the outlet structure. The plug includes integrated locking components such as a keyhole or combination dial, allowing the safety function to be added without complicating the outlet infrastructure.
3Object-affected harmful factors
If existing outlets are modified to add locking features, then safety is improved, but manufacturing precision requirements increase
Solution Approach 1:
The locking functionality is segmented into a separate, standalone plug component rather than being integrated into the outlet structure. This allows the outlet to remain unchanged and maintains compatibility with existing infrastructure, while the plug itself contains all necessary locking mechanisms.

AI summary
The present invention comprises a method and a device for connecting and locking electrical plugs into power outlets. This prevents plugs from being shaken or accidentally withdrawn, and hence avoids any disturbance of electric current or occurrence of electric spark which may cause fires. In the case where no plug is plugged in, the current invention blocks the socket openings to prevent children from tampering with it or trying to insert any metal objects therein that might expose them to electric shocks. By this invention, an adult can connect and lock electrical plugs easily while it is impossible doing it by children. There are various embodiments of this invention making it suitable for use in many fields that need a continuous electrical feed without interruption such as home appliances, computers, factory equipment, and medical devices among many other examples.
