Sump Junction Box with Sealed Wire Inlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for making electrical connections in sumps are labor-intensive and require separate conduit fittings, with junction boxes often positioned below the water table, making them prone to moisture issues and difficult to install.
Innovation Solution
A sump junction box system that integrates multiple electrical wires, featuring a body with inlets and outlets that allow wire connections to be made easily and sealed with a potting compound, reducing the need for separate conduit fittings and elevating the junction box above the water table for better protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual wires are connected through separate conduit fittings with epoxy sealing, then electrical connections can be made, but the process becomes labor intensive and requires multiple separate components
Solution Approach 1:
The patent combines multiple separate conduit fittings and sealing operations into a single integrated junction box assembly. The junction box includes multiple pre-formed openings that accept wires directly, eliminating the need for separate conduit fittings for each wire. The grommet and seal assembly provides unified sealing for all openings, reducing the number of discrete components and simplifying installation while maintaining electrical connection reliability.
Solution Approach 2:
The junction box serves multiple functions simultaneously: it provides structural support for wire connections, seals multiple openings, protects against moisture and corrosion, and facilitates electrical connections. The single assembly performs what previously required multiple separate conduit fittings, sealing materials, and mounting components, thereby reducing device complexity while maintaining connection reliability.
2Ease of operation
If junction box is positioned in lower portion of sump, then it is easier to access for wire connections, but it becomes positioned below water table and prone to moisture issues
Solution Approach 1:
The patent converts the harmful effect of moisture exposure into a benefit by implementing a robust sealing system. The grommet and seal assembly creates a fluid-tight barrier that protects the electrical connections from moisture while allowing the junction box to remain in the lower, more accessible position. This transforms the previously harmful environmental condition into an acceptable design parameter, maintaining ease of operation while eliminating moisture-related risks.
Solution Approach 2:
The grommet and seal assembly act as an intermediary between the junction box and the external environment. This intermediate sealing layer allows the junction box to be positioned in the moisture-prone lower portion of the sump while protecting the internal electrical connections from harmful moisture exposure. The seal mediates between the need for accessibility and the need for protection, enabling both goals to be achieved simultaneously.
3Adaptability or versatility
If multiple separate conduit fittings are used for each wire, then individual wire connections can be made, but installation time and labor increase
Solution Approach 1:
The patent merges multiple separate conduit fitting operations into a single pre-assembled junction box unit. All wire connections are made through pre-formed openings in the junction box, eliminating the need to install separate conduit fittings for each wire. This combining of functions maintains the adaptability to connect individual wires while dramatically improving installation speed by reducing the number of discrete assembly steps required.
4Adaptability or versatility
If conduit fittings are separately supplied and secured, then flexible wire routing is possible, but the system requires additional components and assembly steps
Solution Approach 1:
The patent combines the wire routing function previously provided by separate conduit fittings into the integrated junction box structure. The pre-formed openings in the junction box provide flexible wire routing capabilities while eliminating the need for separately supplied conduit fittings. This maintains adaptability for various wire routing configurations while reducing device complexity by consolidating multiple components into a single integrated assembly.

AI summary
A system including a sump having an inner volume and a junction box coupled to the sump. The junction box has a body defining an inner volume, and also has a first inlet and a second inlet, wherein each inlet is in fluid communication with the inner volume of the body. The junction box further has a first outlet and a second outlet, wherein each outlet is in fluid communication with the inner volume of the body such that a first wire is positionable in the first inlet and the first outlet and a second wire is positioned in the second inlet and the second outlet.
