Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple transfer system is used for viscous liquid, then device complexity is reduced, but transfer efficiency and reliability deteriorate
Solution Approach 1:
The system divides the transfer mechanism into separate functional components: a liquid passage for viscous liquid flow and a distinct air passage for air discharge. This segmentation allows each passage to be optimized for its specific function, ensuring reliable transfer of viscous liquids while maintaining simple overall system design.
Solution Approach 2:
The air passage includes a reduced passage section with specifically adapted dimensions located at a particular position inside the bottle to be recharged. This local modification creates appropriate flow resistance for viscous liquids while maintaining simplicity elsewhere in the system.
2Ease of operation
If gravity-only transfer is used, then ease of operation is improved, but control over liquid flow and refill level deteriorates
Solution Approach 1:
The system enables automatic flow cessation through the reduced passage section in the air passage, which inherently limits liquid rise based on viscosity. The system self-regulates the refill process without requiring user intervention or complex control mechanisms, achieving both ease of operation and adequate refill level control.
3Ease of operation
If air passage section is uniformly large, then ease of operation is improved, but liquid flow control deteriorates
Solution Approach 1:
The air passage features a reduced passage section with specifically adapted dimensions located at a particular position inside the bottle to be recharged. This local restriction creates appropriate flow resistance for viscous liquids, controlling the liquid flow and refill level while maintaining a simple overall system design.
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 system enables seamless transfer of viscous liquids without user intervention, controlling the refill level and ensuring the flow stops or slows down automatically, suitable for liquids with viscosities of 20 to 25 centipoises.
Implementation Method 1
The gesture-based implementation of such a system is particularly simple for the user. Moreover, the design of the system is such that the flow of liquid from the source bottle to the bottle to be recharged is stopped or at least slowed down automatically
Implementation Method 2
an air passage distinct from the liquid passage and which extends from the interior to the exterior of the bottle to be recharged through the aperture of the bottle to be recharged so as to allow the discharge of air from the bottle to be recharged while liquid is transferred
Implementation Method 3
a part surrounding the liquid conduit coaxially and providing with the liquid conduit one or several radial spaces defining a reduced passage section of the air passage which is adapted to the viscosity of the liquid, the reduced passage section of the air passage being disposed inside the bottle to be recharged above the opening end of the liquid conduit so as to stop, or at least slow down, the rise of liquid in the bottle to be recharged

AI summary
System for recharging with viscous liquid a bottle to be recharged from a source bottle inverted above the aperture of the bottle, comprising:a liquid passage opening out through one end inside the bottle,a distinct air passage, which extends from the bottle to the bottle and putting into communication the interior of the bottle and the bottom of the bottle for the rise of air towards the latter, while liquid is transferred from the bottle to the bottle via the liquid passage,a device for restricting the air passage disposed inside the bottle above the end so as to stop, or at least slow down, the rise of liquid in the bottle, and therefore the flow of liquid, when the liquid level in the bottle reaches the restriction device.
