Outlet Safety Cover With Removable Caps And Slot Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing children from accessing electrical sockets often require replacing the outlet, which is expensive and not economical, whereas a cost-effective and easily installable solution is needed to cover electrical sockets while allowing adult access.
Innovation Solution
A removable cap system with four locking legs that attach to a standard electrical outlet cover plate, featuring slot housings and a spring mechanism for secure locking and easy removal, allowing the cap to be locked into place and easily detached by adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable cap system with locking legs is used, then child safety is improved, but device complexity increases
Solution Approach 1:
The safety device is divided into separate components: a cover plate that fits over the outlet and removable caps that attach to the cover plate. Each cap is an independent unit with its own locking mechanism, allowing the system to provide comprehensive safety while maintaining simplicity through modular design.
Solution Approach 2:
The locking mechanism uses an intermediary slot housing structure that mediates between the cap and the cover plate. The slot housing receives the locking legs and provides a controlled interface for attachment and detachment, simplifying the overall interaction while ensuring secure locking.
2Reliability
If a secure locking mechanism is implemented, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The slot housing has an asymmetric geometry with a wide opening at one end and a narrower section at the other. The locking legs are designed to insert through the wide opening and lock against the narrower section, creating a secure attachment that requires deliberate action to release while remaining simple in structure.
Solution Approach 2:
Instead of requiring complex unlocking mechanisms, the design inverts the approach by using spring-loaded locking legs that automatically engage when the cap is inserted. The secure locking action occurs passively during insertion, while active pressure is only needed for removal, reversing the typical expectation that locking requires effort.
3Ease of manufacture
If replacement of electrical outlets is avoided, then cost is reduced, but effectiveness in preventing access deteriorates
Solution Approach 1:
The cover plate and caps are designed as universal components that can be installed on any standard electrical outlet without modification. The system provides multi-functionality by serving as both a safety device and a universal retrofit solution, eliminating the need for outlet replacement while maintaining effective access prevention.
Solution Approach 2:
Instead of replacing expensive electrical outlets, the invention uses inexpensive cover plates and caps that can be easily manufactured and distributed. These simpler, cheaper components provide the necessary safety function without requiring costly infrastructure changes, making the solution economically viable for widespread adoption.

AI summary
An electrical outlet safety cover consisting of a cover plate and removable caps to cover and prevent access by children to underlying electrical outlet. The cover plate replaces a standard electrical cover plate on an electrical outlet and fastens to the electrical outlet with an attachment screw in the center of the safety cover. The rear side of the cover plate is provided with slot housings on the top sides and bottom on each electrical socket access opening into which legs, provided on the child-proof safety caps, insert as a means of fastening or removing the caps over the electrical outlet. A slot housing surrounds each slot to prevent the legs on the safety cap from inserting too far inward when inserting or removing the caps from the cover plate. The caps are sufficiently large to cover the attachment screw and to prevent choking by a child.
