Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting stainless steel pipes with large diameters is challenging due to the difficulty in site installation, requiring skilled engineers and incurring high costs, as existing methods like welding are complex and costly, and synthetic resin coating solutions are expensive and cumbersome.
Innovation Solution
A clamp with an arc-shaped clamping body and a pressing part that gradually protrudes to secure the pipe, combined with a flange and packing system for watertightness, allowing easy installation without specialized tools and preventing corrosion by using stainless steel materials throughout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding operation is performed to connect stainless steel pipes with diameter of 80A or more, then connection is achieved, but skilled engineers are needed and working process is delayed
Solution Approach 1:
The patent replaces the welding operation (thermal/chemical process) with a mechanical connection system consisting of a clamp and pressing part. The clamp mechanically secures the pipe to the flange through the pressing part, eliminating the need for welding skills and reducing installation time while maintaining connection reliability.
2Ease of manufacture
If cast iron pipe is adopted for water pipe with diameter of 80A or more, then pipes can be connected, but pipes are heavy and difficult to be transported and installed
Solution Approach 1:
The patent segments the pipe system into separate components: stainless steel pipes, flanges, and clamps. This allows the use of lightweight stainless steel pipes while the connection function is provided by separate flange-clamp assemblies, eliminating the need for heavy cast iron pipes while maintaining ease of connection.
3Reliability
If synthetic resin coating layer is formed on outer surface of stainless steel pipe, then corrosion resistance is improved, but manufacturing costs are expensive and pre-task is needed
Solution Approach 1:
The patent uses stainless steel material inherently possessing corrosion resistance properties, eliminating the need for additional synthetic resin coating layers. The material itself provides the protective function, reducing manufacturing costs and installation complexity while maintaining corrosion resistance reliability.
4Stability of the object's composition
If stainless steel pipe with high rigidity is used, then structural stability is improved, but it is relatively difficult to fix clamp for connecting fittings
Solution Approach 1:
The patent applies local quality by concentrating the clamping force at specific locations through the pressing part design. The pressing part gradually protrudes toward the center of the clamping body, creating localized pressure points on the pipe surface. This allows effective clamping of rigid stainless steel pipes without requiring complex installation procedures, as the force is applied precisely where needed.

AI summary
A clamp is provided which can be mounted on a flange for connecting a second pipe to a first pipe to prevent the second pipe from being separated. The clamp includes a clamping body formed by coupling at least two assembly members each of which has an arc shape; and a pressing part disposed inside the clamping body to press an outer circumferential surface of the second pipe that is inserted into the clamping body, wherein the pressing part gradually protrudes toward a center of the clamping body along a direction in which the second pipe is inserted to allow the second pipe to be easily inserted and prevent the second pipe from being separated.
