Elastic Hose Clamp for Volumetric Pump Force Peak Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical hose clamps face issues with high force peaks during closure due to varying hose designs and dimensions, leading to operational difficulties and safety risks, particularly in infusion pumps where unintended 'free-flow' situations can occur if the locking system fails to secure properly.
Innovation Solution
The introduction of an elastically movable coupling between the clamping sections via connecting members, which decouples the force flow and allows for secure positioning, reducing the risk of unintentional loosening and enhancing the locking mechanism's reliability by absorbing stress peaks and maintaining intended rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the two clamping legs are rigidly connected to ensure secure locking, then the locking reliability is improved, but high force peaks occur during closure due to varying hose dimensions and elasticity
Solution Approach 1:
The clamping leg is designed with elastic mobility through connecting members (such as elastic arms or springs) that allow dynamic adjustment during the clamping process. This enables the system to absorb force peaks when closing while maintaining secure locking when latched, transforming the rigid connection into a dynamically adaptable one that responds to varying hose dimensions and elasticity.
2Stability of the object's composition
If the clamping jaw is rigidly connected to the clamping section, then structural stability is improved, but the locking system may not securely latch due to force peaks
Solution Approach 1:
The clamping jaw is elastically connected to the clamping section via connecting members, allowing the jaw to move independently during closure to absorb force peaks. This dynamic connection maintains structural stability of the overall assembly while ensuring the locking system can securely latch without being compromised by excessive forces.
Solution Approach 2:
The clamping leg is divided into distinct functional sections: a rigid clamping section for secure positioning and locking, and an elastic connecting member with movable jaw for absorbing closure forces. This segmentation allows each part to perform its specific function optimally without interfering with the other.
3Ease of operation
If manual force is applied to close the hose clamp against high force peaks, then the clamping action is achieved, but operator effort increases and safety risk rises
Solution Approach 1:
The elastic connecting members automatically absorb force peaks during closure, reducing the manual force required from the operator. This dynamic force absorption mechanism prevents unintended loosening and reduces safety risks associated with improper clamping, making the operation easier and safer.
