Explosion-Protected Module Arrangement with Segmented Receiving Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof arrangements for electrical and electronic components in potentially explosive areas are costly and complex to assemble, particularly when using individual encapsulation methods for light-emitting diodes.
Innovation Solution
An explosion-proof arrangement featuring a carrier with multiple components and a transparent, seam-free covering body that forms a non-positive or positive connection using a connecting device, allowing for easy assembly and modular construction, with each receiving chamber being partially transparent and having a small volume to minimize pressure in case of an explosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual encapsulation of light-emitting diodes is used, then explosion protection is achieved, but manufacturing cost increases significantly
Solution Approach 1:
The patent merges multiple individual encapsulation functions into a single common housing structure. Instead of encapsulating each light-emitting diode separately, the invention provides a common housing that contains multiple LEDs and their carriers, reducing the number of encapsulation operations and associated costs while maintaining explosion protection for each LED individually through separate compartmentalization within the common housing.
2Reliability
If individual encapsulation of light-emitting diodes is used, then explosion protection is achieved, but assembly complexity increases
Solution Approach 1:
The patent combines multiple encapsulation operations into a single assembly process. The common housing is designed to receive multiple LED carriers simultaneously, and the sealing mechanism is implemented once for the entire assembly rather than separately for each LED. This merging of operations significantly reduces assembly complexity while maintaining the explosion-proof enclosure for each individual LED.
3Reliability
If a sealed housing is used for all components, then explosion protection is achieved, but heat dissipation efficiency decreases
Solution Approach 1:
The patent segments the internal space of the common housing into separate compartments, each containing an individual LED carrier. This segmentation allows for targeted heat management where each LED can be thermally managed independently through its own heat sink structure, while the overall common housing provides the explosion-proof enclosure. The segmentation prevents heat accumulation from one LED from directly affecting others while maintaining the sealed environment for explosion protection.

AI summary
The invention relates to an explosion-protected arrangement (5), which can be formed of a plurality of modules (49). Each module (49) has at least one covering part (20) and at least one carrier (13). The carrier (13) has a carrier face (12), on which electrical and/or electronic components (6) are arranged and in electrical contact. The covering body (20) has an underside (21), which is assigned to the carrier face (12) and in which a plurality of receiving chambers (22) is made. Each receiving chamber (22) is open via an opening (23) only on the underside (21) and is otherwise closed by the covering body (20). Webs (25) having web faces (26) delimit the openings (23) and receiving chambers (22). When a connection is made between the covering body (20) and the carrier (13), each component (6) is enclosed in an annular manner by a web (25), the web face (26) forming a flame-proof gap (27) with the associated section of the carrier face (12).
