Solution Overview
Problem
Existing beverage preparation machines requiring two motors and a three-way valve to handle different types of containers are costly to manufacture and use.
Innovation Solution
A beverage preparation machine with a single motor actuating a movable valve to selectively supply fluid to either a first or second extraction device, depending on the type of container, reducing the need for additional motors and valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two motors and a three-way valve are used to handle different container types, then the machine can prepare beverages from multiple container types, but the manufacturing cost and operational cost increase
Solution Approach 1:
The single motor is designed to perform multiple functions: it directly actuates the first extraction device and indirectly actuates the valve to control fluid distribution to either the first or second extraction device. This multi-functionality eliminates the need for separate motors for each extraction device and reduces the overall system complexity while maintaining the ability to handle different container types
Solution Approach 2:
The patent combines the actuation functions into a single motor system. The motor is mechanically linked to both the first extraction device and the valve through shared mechanical elements (such as the actuating device and linkage mechanisms), merging what would traditionally require separate motor systems into one integrated actuation system
2Ease of operation
If two motors are used to actuate different extraction devices, then each device can be independently controlled, but the manufacturing cost increases
Solution Approach 1:
The single motor maintains independent control capability by using a valve as an intermediary. The motor controls fluid distribution to either the first or second extraction device through the valve, enabling independent operation of each extraction device while using only one motor, thus reducing manufacturing cost while preserving operational independence
3Adaptability or versatility
If a three-way valve is used to control fluid supply to different devices, then fluid can be directed to either extraction device, but the manufacturing cost and operational cost increase
Solution Approach 1:
The valve is integrated into the system as a multi-functional component that is indirectly actuated by the single motor. It controls fluid distribution to either the first or second extraction device, providing the necessary adaptability while being part of a simplified actuation system that reduces overall manufacturing cost
