Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portion capsules are not specifically designed for particular coffee machines, leading to safety issues and potential damage when used in incompatible machines.
Innovation Solution
A portion capsule with a unique identifier that ensures compatibility with specific coffee machines, featuring optical properties, mechanical features, and sensor detection to prevent incorrect capsule insertion, and a design with grooves for enhanced stability and extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an identifier is placed on the lid film, then capsule identification is enabled, but the identifier is exposed to heat and pressure during storage and transport which can damage it
Solution Approach 1:
The identifier is relocated from the lid film (top surface) to the peripheral flange (side surface) of the capsule. This dimensional relocation places the identifier in a protected zone that is not exposed to heat and pressure during storage and transport, while still being accessible to detection means in the insertion chute.
2Reliability
If an identifier is placed on the outer wall of the capsule body, then capsule identification is enabled, but the identifier may interfere with the extraction process
Solution Approach 1:
The identifier is positioned on the peripheral flange at the edge of the capsule rather than on the outer wall of the capsule body. This spatial relocation ensures the identifier does not interfere with water flow or the extraction process, while remaining detectable by sensors in the insertion chute.
3Reliability
If mechanical means are provided in the insertion chute to prevent wrong capsule insertion, then compatibility control is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical blocking mechanisms with a simpler optical/electromagnetic detection system. A detection means (sensor) reads the identifier on the capsule, and a control unit processes this information to enable or disable machine operation, eliminating the need for complex mechanical interlocking or blocking mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents incorrect capsule usage, ensures safe operation, and improves the extraction process by ensuring only compatible capsules are used, enhancing safety and efficiency.
Implementation Method 1
The identifier is preferably a surface area with different optical properties, for example reflection properties
