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

VSEngineering 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

Engineering Contradiction:
Improveassembly and disassembly operationsVSAvoidring structure
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvefixation consistencyVSAvoidassembly efficiency
Core Design Contradiction:
ReliabilityVSProductivity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvering productionVSAvoidclamping action uniformity
Core Design Contradiction:
Ease of manufactureVSStrength

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.

Inventive Principle:
Principle #3Local quality

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).
