Segmented Explosion-Proof Housing Covers for Easier Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof housings face difficulties in handling and assembly due to the weight and size of large, heavy covers needed to withstand explosion pressure, which complicates access and installation of electrical and electronic devices.
Innovation Solution
The design features a housing body with a frame part and multiple separate covers that can be individually opened and closed, forming flameproof gaps, allowing for easier handling and assembly by separating the housing opening into sections, with a connection arrangement that simplifies attachment and maintains a flameproof seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large cover is used to close the housing opening to withstand explosion pressure, then the explosion protection is improved, but the weight and handling difficulty of the cover increases
Solution Approach 1:
The housing opening is divided into multiple sections by frame parts with webs, allowing the use of multiple smaller covers instead of one large cover. Each smaller cover can be handled more easily while collectively providing the same explosion protection as a large cover would provide alone.
2Reliability
If a large cover is used to close the housing opening to withstand explosion pressure, then the explosion protection is improved, but the complexity of hinges and assembly mechanisms increases
Solution Approach 1:
The housing opening is divided into multiple sections by frame parts with webs, allowing the use of multiple smaller covers instead of one large cover. Each smaller cover can be handled more easily while collectively providing the same explosion protection as a large cover would provide alone.
3Ease of operation
If the housing opening is made wide to allow device installation, then the accessibility is improved, but the size and weight of the cover required to withstand explosion pressure increases

AI summary
An explosion-protected housing having a housing body, a frame part and at least two separate covers. The housing body delimits an interior space which is open at one side by means of a housing opening. The frame part has a circumferential web surrounding the housing opening. Extending within the circumferential web is a central web of the frame part that divides the housing opening into at least two opening portions. A cover abutment surface is formed, against which the covers bear in their closed position. An encirclingly closed flameproof gap is formed between each cover and the cover abutment surface when the cover is situated in the closed position and is detachably fastened by means of one or more connecting units to the frame part.
