Absorption Refrigeration Coupling With Elastic Gasket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coupling structures for absorption refrigeration circuits, which rely on welding or brazing, are labor-intensive and costly, making them unsuitable for mass production, and the use of metal gaskets with blade parts on flanges increases manufacturing expenses.
Innovation Solution
A coupling structure featuring two coupling members with a gasket and bolts, where the gasket has a protruding part that elastically deforms to prevent fluid leakage, allowing for cost-effective manufacturing without the need for expensive flanges or torque wrenches, using a 'V'-shaped or tapering protruding part and bolts with a weak point for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding or brazing is used to connect pipe conduits and components, then the connection is strong and reliable, but the process becomes labor-intensive and unsuitable for mass production
Solution Approach 1:
The invention divides the connection system into separate components: coupling members with flat adjoining faces, a gasket with sealing protrusions, and bolts. This segmentation allows each component to be manufactured independently and assembled through simple bolting operations, enabling mass production while maintaining reliable connections through the gasket sealing mechanism
Solution Approach 2:
The gasket acts as an intermediary element between the coupling members, providing the sealing function that would otherwise require complex welding or brazing processes. The gasket with its elastic protrusions mediates the connection, ensuring fluid-tight sealing while allowing for easy assembly and disassembly
2Reliability
If a metal gasket with blade parts and grooves is used in the coupling structure, then the sealing performance is improved, but the manufacturing cost increases due to expensive flanges with blade parts
Solution Approach 1:
Instead of providing blade parts on the flanges that engage with the gasket (as in conventional designs), the invention inverts the approach by providing elastic protrusions directly on the gasket itself. This reversal eliminates the need for expensive blade parts on coupling members while maintaining effective sealing through the gasket's own sealing structures
Solution Approach 2:
The gasket with integrated elastic protrusions can be manufactured as a relatively simple, inexpensive component that provides all necessary sealing functions. Rather than investing in expensive, complex flange designs with blade parts, the invention uses a simpler gasket design that achieves the same sealing performance at lower cost
