Customizable Non-Conductive Safety Enclosure for DUT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety enclosures for devices under test (DUTs) using metallic components pose a risk of electrical shock and arcing due to their conductive nature, and often require users to independently design, fabricate, and assemble custom solutions, which can be time-consuming and error-prone.
Innovation Solution
A customizable safety enclosure made of non-conductive materials, such as plastic, featuring removable corner and edge joints that snap fit together without fasteners, providing a secure, electrically insulative barrier and allowing for easy assembly and disassembly, along with features like cable egress openings, edge guards, and an access door with non-conductive hinges, to prevent exposure to hazardous voltages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic panels or molded-in features are used for safety enclosures, then structural strength and durability are improved, but electrical shock and arcing risks increase due to conductive nature
Solution Approach 1:
The patent changes the electrical conductivity parameter of the enclosure material from conductive (metal) to non-conductive (molded plastic), eliminating the arcing and shock risk while maintaining structural integrity through the molded design
Solution Approach 2:
The patent uses molded-in metal inserts embedded within non-conductive molded plastic material, creating a composite structure that provides both structural strength from the metal reinforcement and electrical insulation from the plastic matrix
2Adaptability or versatility
If users independently design and fabricate custom safety enclosures, then customization and adaptability are improved, but time consumption and complexity increase
Solution Approach 1:
The patent divides the safety enclosure into separate modular components (side walls, top, bottom, door) that can be independently manufactured and then quickly assembled together, reducing overall assembly time while maintaining customization options
Solution Approach 2:
The patent incorporates self-aligning and self-latching features in the molded design, allowing users to assemble the enclosure without specialized tools or fasteners, making the assembly process intuitive and rapid
3Ease of operation
If removable corner joints without fasteners are used, then ease of assembly and disassembly are improved, but structural stability may be compromised
Solution Approach 1:
The patent combines multiple functions into the molded corner joints: structural connection, alignment reference, and latching mechanism are integrated into single molded components that provide both ease of assembly and structural stability
Solution Approach 2:
The patent uses molded-in flexible retaining features and snap-fit mechanisms in the corner joints that allow for easy assembly/disassembly while maintaining structural integrity when assembled, utilizing elastic deformation of the molded material

AI summary
A customizable safety enclosure for a device under test (DUT) includes a plurality of non-conductive panels to enclose the DUT, and a plurality of non-conductive removeable corner joints each configured to secure a corner of the enclosure. A method of supplying a customized safety enclosure for a DUT to a customer includes receiving information from the customer about the DUT size and testing environment, fabricating one or more variable components of the enclosure, producing custom assembly instructions for the enclosure, packaging a plurality of components of the enclosure including the variable components and one or more fixed components, and sending the package of components and the custom assembly instructions to the customer.
