Explosion-Proof Fastener Plug Structure for Compact Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof structures face challenges in reducing size due to the need for flanges with insertion and fastening holes, limiting their compactness and increasing costs.
Innovation Solution
An explosion-proof structure is designed with a fastener and two internal space-forming members joined by a plug that covers the fastener's head, allowing for reduced size through the use of a recess in the plug to accommodate the fastener's head and a male thread for increased arrangement flexibility, along with a bolt and screw hole configuration for simple fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flanges with insertion and fastening holes are used in existing explosion-proof structures, then the structure can achieve explosion-proof performance, but the size of the structure increases and cost increases
Solution Approach 1:
The patent merges the functions of the fastener head and the sealing plug into a single integrated component. The fastener includes an integrated head portion that serves both as the fastening element and as the sealing surface, eliminating the need for a separate flange structure with insertion and fastening holes. This consolidation reduces the overall structure size while maintaining explosion-proof performance through the integrated sealing and fastening mechanism.
Solution Approach 2:
The fastener head is designed to perform multiple functions simultaneously: it provides the fastening function through threading, creates the sealing surface against the gasket, and serves as the structural element that replaces the traditional flange. This multi-functionality eliminates the need for separate components, reducing size and cost while maintaining the required explosion-proof performance.
2Reliability
If flanges with insertion and fastening holes are used in existing explosion-proof structures, then the structure can achieve explosion-proof performance, but the manufacturing cost increases
Solution Approach 1:
By combining the fastener and sealing plug into a single integrated component, the patent reduces the total number of parts that need to be manufactured, assembled, and quality-checked. This consolidation simplifies the manufacturing process, reduces material costs, and lowers assembly complexity while maintaining the required explosion-proof performance through the integrated design.
Solution Approach 2:
The multi-functional fastener head eliminates the need for separate flange components, reducing the bill of materials and simplifying the manufacturing bill. The single component performs fastening, sealing, and structural support functions, reducing manufacturing steps and quality inspection requirements while achieving the same explosion-proof performance.
3Adaptability or versatility
If a plug is attached to cover the fastener head, then the degree of freedom in fastener arrangement increases, but the structure becomes more complex
Solution Approach 1:
The patent merges the plug and fastener head into a single integrated component, eliminating the need for a separate plug attachment. The integrated fastener head provides the same adaptability and versatility in fastener arrangement while simplifying the overall structure by reducing the number of components and their associated assembly steps.
