Coffee Capsule Machine Automatic Ejection Mechanism for Safe Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee capsule machines are inconvenient to operate and have safety concerns due to the manual removal of used capsules from the brewing cavity.
Innovation Solution
A coffee brewing device with an automatic capsule-dropping mechanism, comprising a movable head assembly, a capsule holder assembly, a driving device, and an elastic reset component, which allows the capsule to automatically fall after brewing by rotating a capsule supporting plate from a supporting to a non-supporting position, facilitated by a ratchet and rack transmission mechanism and a torsion spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of used capsules is implemented, then device structure is simple, but operation convenience deteriorates and safety deteriorates
Solution Approach 1:
The capsule supporting plate automatically rotates to the non-supporting position using elastic reset component after brewing, enabling the system to serve itself by ejecting the used capsule without user intervention. This self-service mechanism directly improves operation convenience while accepting increased device complexity through the automatic ejection mechanism.
2Reliability
If manual removal of used capsules is implemented, then device structure is simple, but safety deteriorates
Solution Approach 1:
The automatic capsule ejection system eliminates the need for users to manually remove hot capsules from the brewing cavity. The elastic reset component automatically returns the capsule supporting plate to the non-supporting position, ensuring safe disposal of used capsules without user exposure to hot surfaces or moving parts, thereby improving safety despite increased structural complexity.
3Ease of operation
If capsule supporting plate rotation mechanism is added, then operation convenience is improved, but device complexity increases
Solution Approach 1:
The capsule supporting plate rotates to the non-supporting position to discard the used capsule, then the elastic reset component automatically returns it to the supporting position for the next brewing cycle. This discarding and recovering mechanism automates capsule ejection while maintaining readiness for continuous operation, improving convenience despite added mechanical components.
4Reliability
If automatic capsule ejection is implemented, then safety is improved, but device complexity increases
Solution Approach 1:
The system automatically ejects used capsules through the rotation of the capsule supporting plate driven by the elastic reset component, eliminating the need for manual intervention. This self-service safety mechanism protects users from hot surfaces and moving parts while accepting the complexity of the automatic ejection system.
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
The solution enables convenient operation and enhanced safety by automatically dropping the used capsule, eliminating the need for manual handling and reducing the risk of accidents.
Implementation Method 1
an elastic reset component configured to drive said capsule supporting plate to rotate from said non-supporting position to said supporting position
Implementation Method 2
said transmission mechanism comprises: a ratchet, said ratchet is installed on said rotating shaft, and is configured to rotate with said capsule supporting plate synchronously, said ratchet has a plurality of first teeth at its outer circumference; and a rack, said rack is installed on said movable head assembly
Implementation Method 3
said transmission mechanism is arranged between said capsule supporting plate and said movable head assembly, and is configured to drive said capsule supporting plate to rotate from said supporting position to said non-supporting position
Implementation Method 4
the capsule supporting plate is driven to rotate from the supporting position to the non-supporting position, thereby the raw-material capsule can automatically fall down by the gravity
