Retrofit Kit with Extendable Sockets for Gang Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical outlets in gang boxes often require users to employ long extension cords, which become entangled and create tripping hazards, as they cannot accommodate devices at varying distances without replacing the entire outlet.
Innovation Solution
A retrofit kit with extendable and retractable sockets that can be inserted into existing two-socket outlet gang boxes, allowing users to extend and retract sockets and cords to desired lengths, including dynamic three-prong and USB sockets, without needing to replace the gang box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If users employ long extension cords to reach devices at greater distances, then the reach distance is improved, but the cords become entangled and create tripping hazards
Solution Approach 1:
The patent implements a retractable cord mechanism that allows the cord length to dynamically adjust between extended and retracted states. The cord can be pulled out to extend reach distance when needed, then automatically or manually retracts to eliminate entanglement and tripping hazards. This dynamic length adjustment resolves the contradiction by providing long reach only when necessary.
Solution Approach 2:
The cord length parameter is made variable rather than fixed. The retractable mechanism enables the cord to change its effective length from a short retracted state (eliminating tripping hazards) to an extended state (providing reach). This parameter change allows the system to optimize between reach distance and safety based on operational needs.
2Adaptability or versatility
If existing gang boxes are replaced with custom wall outlets to accommodate extendable sockets, then the adaptability is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The retrofit kit is designed to be universally compatible with existing standard gang boxes without requiring custom installation. The extendable socket mechanism is adapted to fit within the constraints of conventional outlet boxes, allowing the same device to provide both fixed and extendable socket functionality. This universality enables adaptability enhancement while avoiding the complexity of custom outlet replacement.
Solution Approach 2:
The retractable cord and socket assembly is nested within the existing gang box structure. When retracted, the cord and socket components are contained within the outlet box, utilizing the existing space efficiently. This nesting approach allows the extendable functionality to be integrated into the existing infrastructure without requiring larger or custom outlet boxes.
3Ease of operation
If fixed sockets are used in existing gang boxes, then the installation simplicity is maintained, but the flexibility to connect devices at various distances is limited
Solution Approach 1:
The socket system transitions from a static fixed position to a dynamic extendable position. The retractable mechanism allows the socket to move between a retracted position (near the wall) and an extended position (further from the wall), providing flexibility to connect devices at various distances while maintaining a simple installed appearance when not in use.

AI summary
Electrical devices must often be used at distances from wall outlets longer than their respective power cords. Extension cords frequently become entangled and take up floor space, creating tripping hazards. The extendable and retractable sockets disclosed are retrofit kits that can be inserted into commonly used electrical outlet gang boxes. To install, a user simply removes a wall outlet cover, removes the prior existing two socket outlet, and installs one of the retrofit kits. Once installed, the electrical sockets may be extended and retracted to the desired length for connecting electrical devices.
