Milk Sampling System for Group Composition Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring milk composition in dairy herds are either infrequent, laborious, and expensive, or require sensitive equipment that is not reliable in a dairy farm environment, making it difficult to manage and optimize milk production effectively.
Innovation Solution
A method that involves repeatedly measuring milk from multiple animal groups, forming a bulk amount, determining a reference content using external equipment, and using mathematical techniques to infer individual group contributions, allowing for reliable analysis without the need for equipment at milking devices, enabling more frequent and cost-effective monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If analyzing equipment is incorporated into the milking machine, then measurement capability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The invention extracts the measurement function from the milking machine itself and relocates it to external laboratory equipment. Milk samples are collected during milking and then analyzed separately in a laboratory setting, eliminating the need for complex integrated measurement devices in the milking system.
Solution Approach 2:
The invention introduces an intermediary sampling system that collects milk samples during the milking process and transports them to external laboratory equipment for analysis. This intermediary approach allows measurement capability without requiring direct integration of complex equipment into the milking machine.
2Measurement precision
If analyzing equipment is incorporated into the milking machine, then measurement capability is improved, but reliability decreases due to delicate equipment in rough environment
Solution Approach 1:
The invention extracts the measurement function from the milking machine itself and relocates it to external laboratory equipment. Milk samples are collected during milking and then analyzed separately in a laboratory setting, eliminating the need for complex integrated measurement devices in the milking system.
3Productivity
If milk is pumped to the milk tank immediately after milking, then productivity is improved, but measurement capability is lost due to milk mixing
Solution Approach 1:
The invention performs preliminary sampling action during the milking process itself, collecting milk samples from each group before the milk is pumped to the tank and mixed with other groups' milk. This preliminary sampling preserves the ability to measure group-specific composition while maintaining efficient milk handling.
Solution Approach 2:
The invention creates a copy (sample) of the group-specific milk during collection, which is then used for measurement purposes. The original milk flow continues uninterrupted to the tank, while the sample copy preserves the compositional information needed for group-specific analysis.
4Measurement precision
If laboratory testing is performed at set times, then measurement accuracy is improved, but frequency and timeliness of results decrease
Solution Approach 1:
The invention establishes a feedback system where milk samples are collected from each group during regular milking operations and analyzed in the laboratory. The results are then fed back to inform management decisions about the herd, creating a continuous monitoring loop that improves both frequency and timeliness.
Solution Approach 2:
The invention performs preliminary sampling action during the milking process itself, collecting milk samples from each group before the milk is pumped to the tank and mixed with other groups' milk. This preliminary sampling preserves the ability to measure group-specific composition while maintaining efficient milk handling.
