Living-Hinge Splice Box for Live Wire Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for addressing open wiring splices in older homes are either expensive and time-consuming or require disconnecting power to install, as they involve multiple parts and complex installations with steel open splice junction boxes.
Innovation Solution
A one-piece injection molded plastic electrical box with an integrated lid connected via a living hinge and four slots on its walls, allowing wire insertion from all sides, which can be easily installed without power cutoff, using doors that act as clamps to secure wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional steel open splice junction boxes are used, then secure wire containment is achieved, but installation becomes expensive and time-consuming due to multiple parts and complex assembly
Solution Approach 1:
The patent combines multiple traditional junction box components (box body, lid, wire clamps, mounting brackets) into a single integrated plastic housing. The living hinge integrates the lid and box as one piece, while molded-in features provide wire clamping and mounting functions, eliminating the need for separate parts and simplifying installation.
Solution Approach 2:
The single-piece plastic electrical box performs multiple functions: it contains wires, provides structural support, integrates wire clamping mechanisms through molded doors, includes mounting capabilities via integrated brackets, and offers lid closure with latching. This multi-functional design replaces traditional multi-component systems.
2Reliability
If traditional steel open splice junction boxes are used, then secure wire containment is achieved, but installation cost increases due to expensive materials and multiple components
Solution Approach 1:
The patent combines multiple traditional junction box components (box body, lid, wire clamps, mounting brackets) into a single integrated plastic housing. The living hinge integrates the lid and box as one piece, while molded-in features provide wire clamping and mounting functions, eliminating the need for separate parts and simplifying installation.
Solution Approach 2:
The patent uses injection-molded plastic instead of expensive steel materials, creating a cost-effective single-use electrical box that achieves reliable wire containment through integrated design features rather than expensive materials and complex assembly.
3Reliability
If open splice junction boxes are installed, then wire splices are contained, but power must be disconnected during installation which interrupts service
Solution Approach 1:
The patent features pre-formed molded doors with integrated wire clamps that are ready to secure wires immediately upon insertion. The living hinge lid is pre-configured for easy opening and closing, allowing electricians to install the box and secure wires without power disconnection, maintaining service continuity.
4Strength
If multiple screw and part assemblies are used, then secure mounting is achieved, but installation time increases
Solution Approach 1:
The patent combines multiple traditional junction box components (box body, lid, wire clamps, mounting brackets) into a single integrated plastic housing. The living hinge integrates the lid and box as one piece, while molded-in features provide wire clamping and mounting functions, eliminating the need for separate parts and simplifying installation.
Solution Approach 2:
The integrated design features self-aligning molded doors that automatically clamp wires when the lid is closed, and integrated mounting brackets that require minimal fastening steps. The living hinge mechanism provides automatic lid closure assistance, reducing installation time while maintaining secure mounting.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a cost-effective, easy-to-use method for containing open wiring splices, eliminating the need for multiple parts and power disconnection during installation, while ensuring secure wire retention.
Implementation Method 1
The box has an integrated lid which is connected to the body of the box via a living hinge
Implementation Method 2
The bent opening doors act as clamps to secure the wires by applying pressure to the wires as those doors attempt to bend back to their original orientation

AI summary
A one-piece injection molded plastic electrical box. The box has an integrated lid which is connected to the body of the box via a living hinge, also formed during the molding process. Four slots on either of four walls allow wires to enter the box from all sides. These openings have doors are designed to bend down, allowing space for the wires to be inserted. Once all wires are placed within the box, the top lid is closed and latched. The bent opening doors act as clamps to secure the wires by applying pressure to the wires as those doors attempt to bend back to their original orientation. This box may be installed without requiring power to be cut off to the splice connection.
