Removable Electrical Housing for Water-Resistant Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical housings designed for adverse environmental conditions, such as moisture, are often expensive and time-consuming to access for maintenance due to their configuration, which complicates maintenance and repairs.
Innovation Solution
A liquid tight electrical housing system comprising a housing body with removably coupled pieces and coupling components that include electrical enclosure coupling features, allowing for easy access while maintaining protection against water ingress, meeting standards like NEMA 4X for durability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical housing is designed for adverse environmental conditions with sealed configuration, then protection against water ingress is improved, but ease of access for maintenance deteriorates
Solution Approach 1:
The housing body is divided into multiple separable pieces (first housing body piece and second housing body piece) that can be removably coupled together. This segmentation allows the housing to be disassembled for maintenance access while maintaining a sealed protective configuration when assembled, resolving the contradiction between protection and ease of access.
2Reliability
If electrical housing is designed with sealed configuration for adverse environmental conditions, then protection against water ingress is improved, but device complexity increases
Solution Approach 1:
The housing is segmented into multiple pieces with coupling features that simplify assembly and disassembly. The coupling components include features that facilitate easy connection and separation, reducing the operational complexity despite the sealed protective design.
Solution Approach 2:
The coupling components serve multiple functions: they connect housing pieces together, maintain sealing integrity, and enable easy disassembly for maintenance. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.
3Reliability
If electrical housing is designed for adverse environmental conditions, then protection against water ingress is improved, but cost increases
Solution Approach 1:
The housing is divided into multiple separable pieces that can be manufactured independently using standard manufacturing processes. This segmentation allows for more economical production compared to manufacturing a single complex sealed housing, while still achieving the required protection level when pieces are assembled with coupling components.

AI summary
A liquid tight electrical housing is described herein and can include a housing body. The housing body can include a first housing body piece and a second housing body piece removably coupled to the first housing body piece, where the second housing body piece includes a third opening and a fourth opening, where the fourth opening includes a complementary housing coupling feature that removably couples to a housing coupling feature in a second opening of the first housing body piece. The housing can also include a first coupling component disposed in a first opening of the first housing body piece, where the first coupling component is configured to couple to a first electrical enclosure. The housing can also include a second coupling component disposed in the third opening of the second housing body piece, where the second coupling component is configured to couple to a second electrical enclosure.
