Coffee bean package for dispensing a dose of coffee beans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee makers suffer from flavor and aroma loss due to prolonged exposure of coffee beans to ambient air, and residual coffee grounds from previous brewing sessions can contaminate new beans, affecting the taste of freshly ground coffee.
Innovation Solution
A coffee bean package with a dosing device that allows for precise dispensing of a predetermined dose of coffee beans directly to the grinder, minimizing exposure to air and eliminating residual coffee grounds, while a closing mechanism maintains the package's airtightness to preserve flavor and aroma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coffee beans are stored in a coffee bean holder for extended periods, then convenience of operation is improved, but flavor and aroma are lost due to prolonged exposure to ambient air
Solution Approach 1:
The coffee bean package is divided into multiple sealed compartments, each containing a predetermined dose of coffee beans. This segmentation allows the coffee to be dispensed in individual portions while the remaining compartments remain sealed and protected from air exposure, thus maintaining flavor and aroma without requiring long-term storage in a holder.
Solution Approach 2:
The coffee beans are pre-dosed into individual sealed compartments before use. This preliminary action eliminates the need for storing bulk coffee in a holder, as each compartment is ready-to-use and can be sealed immediately after dispensing, preventing any prolonged air exposure that would cause flavor and aroma loss.
2Productivity
If a complete pack of coffee beans is emptied into the coffee bean holder, then productivity is improved, but residual coffee grounds from previous sessions contaminate new beans
Solution Approach 1:
The coffee supply is segmented into multiple sealed compartments rather than stored as a single bulk quantity. Each compartment can be independently dispensed and sealed, preventing cross-contamination between different coffee batches while maintaining high productivity through continuous availability of pre-dosed compartments.
Solution Approach 2:
Each sealed compartment is designed for single-use dispensing, after which it is automatically discarded. This eliminates the problem of residual coffee grounds accumulating in a holder and contaminating subsequent batches, as there is no residual material left in the dispensing mechanism after each compartment is used.
3Object-affected harmful factors
If coffee beans are ground a short time before brewing, then flavor and aroma are preserved, but the complexity of the device increases due to integrated grinder and dosing mechanisms
Solution Approach 1:
The coffee beans are pre-dosed into precise portions within sealed compartments before use. This preliminary dosing action eliminates the need for complex integrated grinding and dosing mechanisms, as the correct amount is already prepared and sealed. The device complexity is reduced while still achieving fresh grinding just before brewing by simplifying the overall system architecture.
Solution Approach 2:
The dosing function is extracted from the main coffee machine body and incorporated into the replaceable coffee bean package itself. This extraction simplifies the main device by removing the need for complex integrated dosing mechanisms, while still enabling precise dosing and fresh grinding just before brewing through the simplified package design.
