Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical detection means are used to detect identifiers on portion packs, then the reliability of portion pack identification is improved, but the detection surface becomes contaminated during operation which reduces detection reliability
Solution Approach 1:
The cleaning means are activated before the optical detection means performs identification to prevent contamination from affecting the detection process. The chamber parts are moved to clean the detection surface in advance, ensuring the optical detection means operates on a clean surface throughout the beverage preparation process.
Solution Approach 2:
The device performs self-cleaning of the optical detection means using its own mechanical components. The chamber parts that move during normal operation are utilized to clean the detection surface, eliminating the need for separate manual cleaning operations and ensuring continuous reliable detection.
2Reliability
If the chamber parts are moved between open and closed positions during each use cycle, then the detection surface is cleaned automatically improving reliability, but the device complexity increases
Solution Approach 1:
The chamber parts serve dual functions: they close the chamber during beverage preparation and simultaneously clean the optical detection means during their movement. This multi-functionality eliminates the need for separate cleaning mechanisms, reducing overall device complexity while maintaining reliable detection surface cleanliness.
Solution Approach 2:
The cleaning function is merged with the chamber closing operation. The same mechanical movement that closes the chamber also performs the cleaning action, combining two functions into one mechanical sequence and avoiding additional complex cleaning mechanisms.
