Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fully automatic coffee machines are bulky, have a high number of mechanical components that require frequent maintenance due to contamination, and are not compatible with modern restaurant designs.
Innovation Solution
A compact coffee machine design featuring a single grinder and single brewing chamber, with a user interface and control unit that allows selection of coffee-based drinks and control of operating parameters, and a method that minimizes contamination by using separate coffee bean containers and a selecting unit to prevent coffee bean mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple grinders and brewing chambers are used to provide coffee-based drinks from different coffee blends, then the versatility of the coffee machine is improved, but the device complexity and maintenance requirements increase
Solution Approach 1:
A single grinder and single brewing chamber are designed to perform multiple functions by processing different coffee blends. The system uses one grinder that can handle various coffee bean types and one brewing chamber that can prepare different coffee-based drinks, eliminating the need for separate dedicated units for each coffee blend while maintaining full versatility
Solution Approach 2:
Multiple coffee bean containers are merged into a single grinder system, and multiple brewing operations are consolidated into one brewing chamber. This combining of functions reduces the overall number of mechanical components while preserving the ability to prepare diverse coffee-based drinks from different coffee blends
2Adaptability or versatility
If multiple grinders and brewing chambers are used to prepare different coffee-based drinks, then the versatility is improved, but the maintenance needs increase due to more mechanical components exposed to contamination
Solution Approach 1:
The system merges multiple coffee bean containers into a single grinder and multiple brewing functions into one brewing chamber, reducing the total number of mechanical components that require maintenance. Fewer components mean fewer parts exposed to coffee powder and water contamination, thereby reducing maintenance frequency and complexity while maintaining the ability to prepare various coffee-based drinks
3Volume of moving object
If a compact coffee machine design with single grinder and single brewing chamber is used, then the device size is reduced, but the ability to handle multiple coffee blends is limited
Solution Approach 1:
The single grinder and single brewing chamber are designed as universal components capable of processing different coffee blends. The grinder can accommodate various coffee bean types, and the brewing chamber can prepare different coffee-based drinks, allowing the compact device to maintain full versatility despite its reduced size
Solution Approach 2:
The system segments different coffee blends into separate containers while using a shared single grinder and brewing chamber. This segmentation allows multiple coffee blends to be stored separately and selected as needed, preventing contamination while maintaining the compact design with reduced device size
4Object-affected harmful factors
If separate coffee bean containers are used for different blends, then contamination between coffee blends is prevented, but the device complexity increases
Solution Approach 1:
Different coffee blends are segmented into separate containers to prevent contamination. Each container holds a specific coffee blend, and the system selects which container to use based on the desired drink, ensuring that coffee beans from different blends do not mix while maintaining a relatively simple overall device structure
Solution Approach 2:
A selecting unit acts as an intermediary between the multiple coffee bean containers and the single grinder. This intermediary component controls which container is connected to the grinder, preventing direct mixing of different coffee blends while managing the flow of coffee beans through the system with minimal added complexity
