Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clamping rings for peristaltic pumps face challenges in operational capacity and assembly/disassembly efficiency, leading to suboptimal performance and durability issues.
Innovation Solution
A clamping ring with a cylindrical body composed of multiple coupled cylinder portions and a double taper profile, featuring grooves for O-ring or elastic spring integration, facilitating easy assembly and disassembly while ensuring uniform clamping and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional single-piece clamping ring is used, then the structural integrity and sealing are maintained, but the assembly and disassembly operations become time-consuming and complex
Solution Approach 1:
The clamping ring is divided into multiple cylindrical portions (at least two) that can be assembled and disassembled independently. Each portion has grooves for O-ring placement and tapered surfaces for coupling. This segmentation allows quick assembly by simply connecting the portions together, eliminating the need for complex tools or procedures while maintaining structural integrity through the interconnected design.
2Reliability
If a clamping ring with complex configuration is used, then the operational capacity is improved, but the assembly and disassembly operations cannot be performed optimally and repetitively
Solution Approach 1:
The ring is segmented into multiple portions with standardized interfaces, allowing rapid assembly and disassembly while maintaining consistent fixation quality through the tapered coupling surfaces and O-ring sealing grooves.
Solution Approach 2:
The tapered surfaces and grooves are pre-configured on each portion during manufacturing, so that when portions are assembled, the alignment and sealing are automatically achieved without requiring additional adjustment or complex operations, enabling repetitive assembly at high speed.
3Ease of manufacture
If a clamping ring with uniform cross-section is used, then the manufacturing is simplified, but the clamping action and effort distribution become non-uniform
Solution Approach 1:
Each cylindrical portion has a non-uniform cross-section with a double taper profile (different angles at each end) and integrated sealing grooves. This local variation in geometry optimizes the clamping action at different locations, ensuring uniform effort distribution and consistent sealing while still allowing relatively simple manufacturing of each individual portion.

Implementation Method 1
each of these portions having, on their outer surface, a groove supporting the inclusion of an O-ring or elastic spring holding the different portions mutually interlinked in the ring when in its assembled condition
Implementation Method 2
the ring body of which has a cross-section with a double taper of rounded profile, with regard to both ends, which allows close coupling under a certain pressure with the clamping flange element

AI summary
The body of the ring comprises a number of cylinder portions (1), configured to fit on each other and provided with a groove (2) on their outer surface that cuts them across and is located at a position correspondingly equivalent in the different portions, and is sized to internally receive an O-ring (3) that holds the portions mutually connected when the ring is assembled. The body of the ring has a taper of rounded profile, in relation to each of its ends, so that the inner end is coupled closely along the line of contact with the inside of a pump body (4) in which it is located, and the outermost end engages the inner surface complementary configured of a first section (6a) of greater diameter of the through-hole of said clamping flange (6).
