Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological analysis devices face challenges with pipe retention, leading to musculoskeletal disorders and leakage risks due to complex and impractical assembly processes using pneumatic clamps and sleeve fittings.
Innovation Solution
A flange system with a plastic body featuring external and central branches that engage to form annular pockets for clamping pipes, allowing for quick and simple installation, reducing the risk of musculoskeletal disorders and leakage, and accommodating pipes of varying diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pneumatic clamps and sleeve fittings are used to hold pipes on valves, then pipe retention is achieved, but assembly complexity increases and musculoskeletal disorders risk arises
Solution Approach 1:
The flange is divided into multiple branches (first external branch, second external branch, central branch) with recesses that segment the pipe clamping function into distributed contact points, simplifying the overall assembly process while maintaining secure pipe retention
Solution Approach 2:
The flange appears to be a single-use, disposable component that is quickly assembled and discarded with the cartridge, eliminating the need for complex reusable pneumatic clamps and reducing assembly complexity
2Reliability
If a two-part tubing retention system is used, then pipe clamping is achieved, but device complexity and implementation difficulty increase
Solution Approach 1:
Multiple pipe clamping functions are merged into a single integrated flange structure with multiple branches, eliminating the need for separate two-part retention systems and reducing overall device complexity while maintaining reliable tube retention
3Ease of manufacture
If diagonal cutting of pipes and sleeves is performed, then fitting is achieved, but assembly time and complexity increase
Solution Approach 1:
The recesses in the flange branches are designed with specific geometric parameters that accommodate standard pipe outer diameters directly, eliminating the need for diagonal cutting and reducing assembly time while maintaining proper fitting capability

AI summary
The invention relates to a clamp for a biological analysis device which comprises a plastic body that comprises a base (12) to which a first outer branch (6), a second outer branch (10) and a central branch (8) are connected, the first outer branch (6) being longer than the second outer branch (10) and said first outer branch (6) and second outer branch (10) being arranged to engage mutually when the clamp is closed. The first outer branch (6) and the second outer branch (10) each have a first recess (34, 40) and a second recess (32, 38) on the portion oriented towards the inside of the body (4), the first recess (34, 40) being further from the base (12). The central branch (8) has two pairs of recesses (44-46; 48-50) each provided on one side and comprising a first recess (46; 50) and a second recess (44; 48), which are homologous with the first recess (34; 40) and the second recess (32; 38), respectively, of the first outer branch (6) and the second outer branch (10), the second recesses (44; 48) being dimensioned so that the first outer branch (6) and the second outer branch (10) come substantially into contact with the central branch (8) when the clamp is closed, the first recesses (34-46; 40-50) then defining therebetween two annular pockets (54; 58), each suitable for clamping a pipe (56; 60) which it receives.
