Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle filling machines are limited in their ability to efficiently and accurately fill containers of different sizes with non-viscous fluids independently, often resulting in fluid dripping when bottles are removed.
Innovation Solution
A portable machine with multiple discrete stations, featuring peristaltic pump assemblies, a human-machine interface, level sensors, and invertible bottle nests, allows for independent filling of containers of various sizes by sensing the fluid level and reversing the pump to prevent dripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single bottle filling machine is used, then the machine structure is simple, but it cannot efficiently fill containers of different sizes independently
Solution Approach 1:
The filling machine is divided into multiple discrete filling stations (first filling station, second filling station, etc.), each capable of independently filling bottles of different sizes. This segmentation allows parallel operation of multiple stations, significantly improving productivity while maintaining manageable complexity through modular design
Solution Approach 2:
Each filling station is designed with universal capability to handle different bottle sizes through adjustable components such as peristaltic pumps and level sensors. The stations can be configured for various container types, enabling one machine to perform multiple filling functions simultaneously
2Productivity
If continuous fluid flow is used during bottle removal, then the filling process is continuous, but fluid dripping occurs
Solution Approach 1:
The peristaltic pump operates in periodic cycles: filling mode delivers fluid continuously to reach the desired level, then switches to reverse mode to draw fluid back and create a slight vacuum. This periodic reversal prevents fluid dripping during bottle removal while maintaining overall filling continuity through automated station sequencing
Solution Approach 2:
Level sensors detect when the bottle reaches the desired fill level and automatically trigger the pump reversal sequence. This feedback mechanism ensures fluid flow is stopped precisely at the right moment, preventing overfilling and dripping while maintaining efficient continuous operation across multiple stations
3Manufacturing precision
If manual operation is used, then the device is simple to manufacture, but the filling precision and level control are poor
Solution Approach 1:
The filling system uses level sensors that automatically detect when each bottle reaches the desired fill level and trigger the pump reversal without manual intervention. This self-service automation ensures consistent precise filling across all stations while reducing the need for complex manual control mechanisms
Solution Approach 2:
Manual level detection and control are replaced with electronic level sensors and automated pump control systems. This substitution provides precise digital measurement of fill levels and automated response, achieving high manufacturing precision through electronic control rather than mechanical measurement devices

Implementation Method 1
The machine comprises a plurality of discrete stations for filling containers, such as bottles, with fluid independently of each other... A non-viscous fluid is flowed into a container to a desired level
Implementation Method 2

AI summary
Containers of the same or different size are filled with a non-viscous fluid at discrete stations, each container being filled independently of each other container. Multiple containers of the same or different size are positioned at multiple discrete stations, each container being at a different station. A non-viscous fluid is flowed into a container to a desired level. The level is sensed with a level sensor and the fluid flow stopped at the desired level. The fluid flow is reversed to prevent fluid dripping when a filled bottle is removed.
