Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fruit press systems face challenges in filling vessels of different sizes consistently without risking contamination from misdirected juice flows, as the fixed distance between the vessel mounting and the tap restricts adaptability.
Innovation Solution
A vessel mounting system with a holder supported by a weighing cell and a filling level sensor, controlled by a control device, ensures consistent filling by adjusting the drawing valve based on measurement signals, allowing bottles of varying sizes to be filled without overfilling or contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the vessel mounting and the tap is predetermined by design, then the structure is simple and stable, but the adaptability to different bottle sizes is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the holder positionable at multiple locations along the outlet conduit. Instead of a fixed predetermined distance, the holder can be dynamically repositioned to accommodate different bottle sizes. The control device adjusts the holder position based on the detected bottle size, allowing the system to adapt to various filling requirements while maintaining a relatively simple overall structure.
2Manufacturing precision
If the tap position is fixed relative to the vessel mounting, then the manufacturing is simple, but the filling precision for different bottle sizes deteriorates
Solution Approach 1:
The patent applies the universality principle by designing the holder as a multi-functional component that can serve different bottle sizes. The holder is not fixed to a single position but can be relocated along the outlet conduit to match different bottle dimensions. This universal design allows the same vessel mounting structure to accurately fill various bottle sizes, maintaining manufacturing precision without significantly complicating the manufacturing process.
Solution Approach 2:
The holder is designed with dynamic positioning capability, allowing it to be moved to different locations along the outlet conduit. The control device adjusts the holder position based on bottle size detection, ensuring optimal filling precision for each bottle type. This dynamic adjustment mechanism enables high filling precision across different bottle sizes while keeping the overall manufacturing complexity manageable.
3Reliability
If automatic control with sensors and weighing cells is implemented, then the filling consistency is improved, but the device complexity increases
Solution Approach 1:
The patent applies the feedback principle by implementing a control device that receives input from weighing cells and filling level sensors. The weighing cells measure the bottle weight to determine filling consistency, while the filling level sensors monitor the liquid level in real-time. The control device processes this feedback information and automatically adjusts the holder position and filling process to maintain consistent filling across different bottle sizes, significantly improving reliability.
Solution Approach 2:
The patent replaces manual mechanical positioning and monitoring with automated electronic control. Instead of mechanically adjusting the holder position for each bottle size, the control device uses electronic signals from sensors and weighing cells to automatically position and control the filling process. This substitution of mechanical systems with electronic control improves filling consistency while managing the complexity through integration.
4Adaptability or versatility
If the holder position is adjusted for different bottle sizes, then the adaptability is improved, but the positioning precision may deteriorate
Solution Approach 1:
The patent applies the dynamics principle by implementing a controllable holder that can be positioned at multiple predetermined locations along the outlet conduit. The control device selects the appropriate position based on the detected bottle size, ensuring both adaptability and positioning precision. The system maintains precision by using discrete, well-defined positions rather than continuous adjustment, which simplifies the positioning mechanism while still accommodating various bottle sizes.
Solution Approach 2:
The patent applies the preliminary action principle by pre-establishing multiple holder positions along the outlet conduit before the filling process begins. These predetermined positions are optimized for different bottle sizes, allowing the control device to quickly select the appropriate position without complex real-time calculations. This preliminary setup ensures both adaptability to different bottle sizes and precise positioning, as each position is pre-calibrated for optimal performance.

Function Achieved in This Case
Ensures consistent filling conditions for bottles of all sizes by accurately determining the filling volume and preventing overfilling, while maintaining a secure and controlled juice flow, thereby reducing the risk of contamination.
Implementation Method 1
the holder of the vessel mounting is supported on at least one weighing cell so that the respective filling volume can be determined on the basis of the weight measurement
Implementation Method 2
This fill level sensor, which can be designed as a capacitive distance sensor, for example, can be used to detect the remaining fill level above the already filled juice volume

AI summary
A device for drawing juice from a juice container of a fruit press includes an outlet which is connected to the juice container, has a removal valve and is located above a vessel receptacle. In order to provide advantageous structural conditions, the vessel receptacle forms a holder which receives a hanging bottle by the neck thereof, is supported on at least one weighing cell and is assigned at least one filling level sensor. The removal valve can be activated by a control device, which is connected to an input unit, depending on the measurement signals of the weighing cell and of the filling level sensor.
