Hot Beverage Machine Holder Positioning Detection to Prevent Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation machines lack security against incorrect operation and are difficult to clean, particularly due to loose holders that can be incorrectly positioned, leading to potential overflow and user safety risks.
Innovation Solution
A machine with a detachable holder for portion packs that includes markings for recognition, a detection unit with a light source and optical reader to ensure correct positioning, and a spring-loaded valve to prevent water flow in case of incorrect insertion, along with a display for error messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a detachable holder is provided for cleaning purposes, then ease of cleaning is improved, but incorrect positioning can occur leading to safety risks
Solution Approach 1:
The recognition unit detects the holder's positioning status before the beverage preparation process starts. The marking on the holder is read by the recognition unit (light source and optical reader) to verify correct positioning before water is released, preventing incorrect operation while maintaining detachable design for cleaning
Solution Approach 2:
The recognition unit provides feedback about the holder's positioning status to the control system. Based on this feedback, the control system decides whether to allow water flow or block it via the closing device, creating a closed-loop safety mechanism that ensures correct positioning before operation
2Measurement precision
If a recognition system with light source and optical reader is added, then positioning detection accuracy is improved, but device complexity increases
Solution Approach 1:
The recognition system is integrated into the existing holder structure, with the marking being a simple feature on the holder itself rather than a complex separate component. The light source and optical reader are incorporated into the holding device in a compact manner, extracting only the essential detection function while minimizing added complexity
Solution Approach 2:
Instead of using complex mechanical positioning sensors, the system uses an optical copy/recognition approach where a simple marking (visual pattern) on the holder is read by the optical reader. This replaces complex mechanical detection with a simpler optical recognition system that achieves high positioning detection accuracy
3Reliability
If the closing device is provided to block water flow, then safety against overflow is improved, but the risk of scalding from trapped hot water increases
Solution Approach 1:
The recognition unit continuously monitors holder positioning and provides feedback to the control system. Only when correct positioning is confirmed does the control system activate the closing device to allow water flow. This feedback mechanism ensures that the closing device blocks water only when necessary (incorrect positioning), preventing both overflow and scalding risks
Solution Approach 2:
The system performs preliminary detection of holder positioning before allowing hot water to flow. The recognition unit reads the marking and verifies correct positioning in advance, so the closing device is activated to prevent water flow only when positioning is incorrect, eliminating the risk of trapped hot water causing scalding

AI summary
The invention relates to a machine (1) for preparing hot beverages, said machine comprising: a holding device (6) to which a holder (7) for a portioned package (8) is removably applied; a closure device (20) on the holder (7) and/or the holding device (6), said closure device being provided in front of an outlet (24) and by means of which the outlet (24) can be closed and opened; a device for producing hot water with an inlet (4) located above the portioned package (8); and a control system comprising a detection unit (12). At least one marking (11) is provided on the removably applied holder (7), by means of which marking it is possible to detect, using the detection unit (12), whether the holder (7) is correctly positioned on the holding device, and a beverage can only be prepared if the holder (7) is correctly positioned by means of the control system. This makes it possible to avoid maloperations when preparing hot beverages and to reduce the risk of injury to users.
