Teatcup Liner Segmented Barrel Upward Collapse Wave
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teatcup liners do not efficiently provide a gentle teat treatment and adequate teat massage during milking, as they fail to securely collapse the barrel, potentially pressing lymphs downward and resulting in slower milking due to insufficient vacuum shut-off.
Innovation Solution
A teatcup liner with a polygonal cross-sectional barrel design, featuring a lower barrel with greater flexibility than the upper barrel, ensuring the lower barrel collapses first to create an upward wave movement that securely collapses the upper barrel onto the teat, enhancing teat massage and relieving congestion, while maintaining a secure seal to prevent lymph compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a triangular or polygonal cross-sectional barrel is used, then gentle teat treatment is achieved, but vacuum shut-off is insufficient resulting in slower milking
Solution Approach 1:
The barrel is divided into an upper barrel portion and a lower barrel portion with different cross-sectional shapes. The upper portion has a triangular or polygonal cross-section for gentle teat treatment, while the lower portion has a round cross-section for effective vacuum shut-off and faster milking speed.
Solution Approach 2:
Different sections of the barrel are given different geometric properties tailored to their specific functions. The upper section maintains a triangular/polygonal shape to provide gentle massage to the teat tissue, while the lower section transitions to a round shape to ensure complete vacuum shut-off and prevent air leakage.
2Productivity
If the barrel collapses uniformly, then vacuum application is efficient, but lymphs are pressed downward causing harmful effects
Solution Approach 1:
Instead of the barrel collapsing uniformly from all sides, the design enables the barrel to collapse in a wave-like motion starting from the lower portion and moving upward. This inverted collapse pattern ensures that the upper barrel portion collapses last, preventing lymph compression while maintaining vacuum efficiency.
Solution Approach 2:
The barrel collapse occurs in a sequential, wave-like manner rather than simultaneously. The collapse progresses periodically from the lower barrel portion upward, creating a controlled sequence that prevents harmful lymph compression while maintaining efficient vacuum application.
3Object-affected harmful factors
If the upper barrel portion is made more flexible for better collapse, then teat massage is enhanced, but vacuum seal is compromised
Solution Approach 1:
The barrel is segmented into upper and lower portions with different flexibility characteristics. The upper portion is designed with greater flexibility to provide enhanced teat massage, while the lower portion maintains higher rigidity to ensure reliable vacuum seal and prevent air leakage.
Solution Approach 2:
Different flexibility properties are assigned to different sections of the barrel. The upper barrel portion has increased flexibility optimized for gentle teat massage, while the lower barrel portion maintains structural rigidity necessary for maintaining vacuum integrity and preventing air ingress.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures efficient milking with enhanced teat massage and congestion relief, maintaining a secure seal to prevent lymph compression and ensuring the teat is fully contained within the upper barrel during milking.
Implementation Method 1
the lower barrel has a flexibility for closing during the liner collapse phase of the milking operation greater than a flexibility of the upper barrel
Implementation Method 2
the differential pressure across the barrel of the teatcup liner increases and causes the barrel to collapse onto the teat to provide a teat massage

AI summary
A teatcup liner (1) includes a head defining a mouthpiece, a barrel (2) with an upper barrel (3) joined to a lower barrel (4), an outlet portion that extends downward from the lower barrel co-operates with the shell of the teat cup. In a relaxed state, the barrel has a polygonal cross-sectional shape, with the lower barrel having a flexibility for closing during the liner collapse phase of the milking operation greater than a flexibility of the upper barrel such that corner portions (19) of the lower barrel are weaker than the corner portions of the upper barrel thereby assuring the lower barrel collapses first to create an upward wave movement of the lower barrel towards the upper barrel that securely collapses the upper barrel onto the teat to provide an enhanced teat massage and relieve congestion in the teat tissue.
