Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide a simple and safe method for precise temperature control and dosing of fluids, particularly in applications like baby food preparation and coffee brewing, where temperature accuracy and sterility are crucial, and existing solutions often lead to calcification and require extensive cleaning.
Innovation Solution
A stroke system incorporating a piston pump with temperature control means, allowing for precise dosing and simultaneous temperature adjustment of fluids, using a piston pump connected to a turntable or linear mechanism, with optional UV-C sterilization and disposable components for hygiene and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a piston pump is used for dosing fluid, then dosing precision is improved, but device complexity increases due to additional temperature control means
Solution Approach 1:
The patent combines the piston pump for dosing with temperature control means into an integrated system. The temperature control means includes a heating element and cooling element that work together with the piston pump to provide both precise dosing and temperature control in a single device, thereby improving dosing precision while managing device complexity through functional integration.
2Temperature
If temperature control means are added to the piston pump, then temperature control capability is improved, but ease of operation deteriorates
Solution Approach 1:
The system incorporates control means that automatically regulate the temperature of the fluid being dosed. The heating and cooling elements are controlled to maintain the desired temperature without requiring manual intervention, allowing the device to serve itself in temperature management while the user simply operates the dosing function.
3Reliability
If disposable components are used, then reliability is improved through sterility, but loss of substance increases due to single-use design
Solution Approach 1:
The system divides components into disposable and reusable parts. The piston pump and temperature control means are designed as reusable components that can be cleaned and sterilized, while only the parts that come into direct contact with the fluid are made disposable. This segmentation maintains sterility and reliability while reducing fluid waste by allowing repeated use of the main system components.
