Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milking installations face issues with incorrect vacuum or underpressure levels in the head pressure of milking cups, leading to reduced milk release and potential infections in animals.
Innovation Solution
A milking liner with an integrated air inlet and pressure compensator, which includes a pressure valve or flow restriction, is used to control and maintain the desired pressure in the teat chamber, ensuring optimal stimulation and reducing the risk of infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no pressure compensator is provided in the air inlet, then the device complexity is reduced, but the head pressure cannot be controlled leading to reduced milk release and possible infections
Solution Approach 1:
The patent applies parameter changes by introducing a pressure compensator that actively regulates the head pressure parameter in the teat chamber. This device monitors and adjusts pressure levels to maintain optimal conditions for milk release while preventing infections, thereby resolving the contradiction between reliability and device complexity through controlled parameter modification.
Solution Approach 2:
The pressure compensator acts as an intermediary element between the air inlet and the teat chamber. It mediates the pressure control function by introducing a regulatory mechanism that balances the need for controlled head pressure with the simplicity of the overall system design, enabling reliable milk release without excessive complexity.
2Productivity
If head pressure is too high, then the animal may not be properly finished milking, but providing a pressure compensator increases device complexity
Solution Approach 1:
The pressure compensator dynamically adjusts the head pressure parameter to prevent it from becoming too high, ensuring proper milk release completion. This parameter control mechanism resolves the contradiction by maintaining productivity through optimized pressure levels while accepting the necessary device complexity for effective regulation.
Solution Approach 2:
The pressure compensator implements feedback control by continuously monitoring head pressure conditions and making adjustments to maintain optimal pressure levels. This feedback mechanism ensures proper milk release by preventing excessive pressure buildup, resolving the contradiction between productivity and device complexity through intelligent pressure management.
3Productivity
If head pressure is too low, then the teat is not properly stimulated and milk release is reduced, but adding pressure control increases device complexity
Solution Approach 1:
The pressure compensator modifies the head pressure parameter to ensure it remains at optimal levels for proper teat stimulation and milk release. By actively controlling this parameter, the system achieves improved productivity through adequate pressure while managing the device complexity required for effective pressure regulation.
Solution Approach 2:
The feedback mechanism in the pressure compensator detects low pressure conditions and activates corrections to maintain optimal head pressure for teat stimulation. This feedback control resolves the contradiction between productivity and device complexity by ensuring adequate pressure levels are maintained through intelligent regulation rather than simple fixed-pressure design.
