Explosive Atmosphere Lighting Apparatus Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting apparatuses for explosive environments require multiple components for sealing and encapsulation, leading to increased costs, size, and weight, with limited versatility and inefficiency in production.
Innovation Solution
A lighting apparatus with a single covering element that cooperates with both sealing and encapsulation elements to provide a sealed and encapsulated housing cavity, reducing the number of components and materials used, while meeting the requirements for immersion tests in explosive atmospheres.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple covering elements and sealing components are used to seal and encapsulate the lighting apparatus, then the sealing reliability is improved, but the device complexity, cost, size, and weight increase
Solution Approach 1:
The patent combines the sealing and encapsulation functions into a single integrated covering element that simultaneously performs both protective roles, eliminating the need for separate sealing elements and reducing overall component count while maintaining protection integrity
Solution Approach 2:
The covering element is designed as a multi-functional component that serves both as a sealing barrier and an encapsulation protective layer, allowing a single element to fulfill multiple protective functions that traditionally required separate components
2Reliability
If multiple covering elements and sealing components are used to seal and encapsulate the lighting apparatus, then the sealing reliability is improved, but the cost increases
Solution Approach 1:
The patent combines the sealing and encapsulation functions into a single integrated covering element that simultaneously performs both protective roles, eliminating the need for separate sealing elements and reducing overall component count while maintaining protection integrity
Solution Approach 2:
The covering element is designed as a multi-functional component that serves both as a sealing barrier and an encapsulation protective layer, allowing a single element to fulfill multiple protective functions that traditionally required separate components
3Reliability
If multiple covering elements are stacked to completely cover the lighting body, then the encapsulation completeness is improved, but the overall size increases
Solution Approach 1:
The patent combines the sealing and encapsulation functions into a single integrated covering element that simultaneously performs both protective roles, eliminating the need for separate sealing elements and reducing overall component count while maintaining protection integrity
Solution Approach 2:
The covering element is designed to nest closely against the lighting body contours, providing complete coverage while minimizing protrusion and overall size increase through form-fitting integration
4Reliability
If multiple covering elements and attachment members are used, then the sealing and encapsulation effectiveness is improved, but the weight increases
Solution Approach 1:
The patent combines the sealing and encapsulation functions into a single integrated covering element that simultaneously performs both protective roles, eliminating the need for separate sealing elements and reducing overall component count while maintaining protection integrity
