Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation machines require manual effort to open and close the brewing device, which can be cumbersome due to varying dimensional tolerances and internal pressures, and may lead to assembly issues and noise during high-speed operation.
Innovation Solution
A motorized beverage preparation machine with an integral transmission frame that directly supports the motor and transmission members, simplifying assembly and reducing manufacturing tolerances, and featuring a movable part that can be slidably or rotatably mounted for efficient ingredient processing and capsule handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual actuation is used to open and close the brewing device, then the device structure remains simple, but the operation becomes cumbersome due to varying dimensional tolerances and internal pressures
Solution Approach 1:
The patent replaces the manual mechanical actuation system with a motorized system. The motor (51) provides automated actuation of the movable part (30), eliminating the need for manual effort to overcome varying dimensional tolerances and internal brewing pressures. This substitution resolves the contradiction by improving ease of operation while accepting increased device complexity through the addition of motorized components.
2Ease of manufacture
If separate components are used for motor and transmission members, then assembly and manufacturing become complex, but integrating them into an integral transmission frame simplifies the structure
Solution Approach 1:
The patent merges the motor (51) and transmission members (52) into a single integral transmission frame (200). This consolidation simplifies assembly by reducing the number of separate components and manufacturing steps, while maintaining the functional complexity needed for motorized actuation. The integral frame approach resolves the contradiction by improving ease of manufacture through reduced assembly complexity.
3Productivity
If high-speed operation is implemented for capsule handling, then productivity increases, but noise and friction wear increase
Solution Approach 1:
The patent replaces manual mechanical operation with a motorized system that enables controlled high-speed operation of the movable part (30). The motor (51) and transmission members (52) work together to achieve rapid capsule insertion and removal, improving productivity. The motorized control allows for optimized speed profiles that can reduce impact noise and friction wear compared to manual high-speed operation.
4Adaptability or versatility
If dimensional tolerances are loosened for capsule compatibility, then adaptability improves, but assembly precision and noise reduction become difficult to achieve
Solution Approach 1:
The patent uses a motorized actuation system with an integral transmission frame to provide controlled movement of the movable part (30). This controlled actuation compensates for variations in capsule dimensional tolerances, allowing the system to accommodate different capsule sizes and specifications. The motorized control enables precise positioning that maintains assembly precision and reduces noise even when adapting to capsules with varying tolerances.

AI summary
A machine (1) for preparing a beverage comprises: a first part (20) and a second part (30) movable relative to the first part; a motor (51,51') having a drive member (510, 511) such as a rotating drive axis; one or more mechanical transmission members ( 52; 521-523; 524-526 ) for transmitting a movement of the drive member to the movable part (30) for moving the movable part; and a transmission frame (200) for supporting the motor and the movable transmission member(s). The transmission frame is an integral component (200) on which the motor and the transmission members are directly mounted.
