Solution Overview
Problem
Conventional rotor hose pumps experience reduced performance and shortened service life due to excessive elongation of the pump hose during operation, requiring frequent manual adjustments and increased maintenance.
Innovation Solution
A rotor hose pump with an adjustable mechanism that allows for automatic retraction of the pump hose during reverse operation, utilizing a locking mechanism with a toothed rack and ratchet catch to maintain hose tension and prevent damage, enabling reliable operation with reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pump hose is used in a rotor hose pump for pumping medium, then the pump can convey material from first connection to second connection, but the pump hose elongates excessively during operation which damages the hose and reduces service life
Solution Approach 1:
The patent applies the dynamics principle by making the holding device movable along the conveying direction instead of fixed. The holding device can dynamically adjust its position to compensate for hose elongation, maintaining proper hose tension and rotor-hose contact. This dynamic adjustment prevents hose damage while preserving pump capacity during operation.
Solution Approach 2:
The patent implements self-service through the automatic adjustment mechanism that moves the holding device along the conveying direction in response to hose elongation. The system automatically compensates for hose length changes without external intervention, maintaining optimal hose tension and preventing damage that would otherwise require manual intervention and reducing service life.
2Reliability
If the pump hose is regularly adjusted manually to counteract elongation, then hose damage is prevented, but maintenance effort and operational complexity increase
Solution Approach 1:
The patent implements self-service through the automatic adjustment mechanism that moves the holding device along the conveying direction in response to hose elongation. The system automatically compensates for hose length changes without external intervention, maintaining optimal hose tension and preventing damage that would otherwise require manual intervention and reducing service life.
Solution Approach 2:
The patent applies feedback through the blocking mechanism that responds to the state of hose tension and elongation. The mechanism detects when the hose has elongated to a critical point and automatically triggers the holding device to move, creating a feedback loop that maintains hose integrity without requiring manual monitoring or adjustment.
3Duration of action of stationary object
If the holding device is made movable to compensate for hose elongation, then hose service life is extended, but device complexity increases due to adjustment mechanism
Solution Approach 1:
The patent applies the dynamics principle by making the holding device movable along the conveying direction instead of fixed. The holding device can dynamically adjust its position to compensate for hose elongation, maintaining proper hose tension and rotor-hose contact. This dynamic adjustment prevents hose damage while preserving pump capacity during operation.
Solution Approach 2:
The patent implements parameter changes by modifying the position parameter of the holding device along the conveying direction. By changing the location where the hose is held, the system compensates for hose elongation without requiring complex mechanical structures, achieving hose protection through a simple positional adjustment.
