Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If size-based detection method is used to identify allergen substances, then detection process is simple, but detection accuracy deteriorates causing wrong identification
Solution Approach 1:
The patent replaces the mechanical size-based detection method with an optical detection system using a light source and photodetector to measure light absorption characteristics. This substitution allows for more accurate identification of allergen substances by analyzing their optical properties rather than relying on size measurements alone, thereby resolving the contradiction between detection simplicity and accuracy.
Solution Approach 2:
The patent changes the detection parameter from physical size to optical absorption characteristics. By measuring how allergen substances absorb light at different wavelengths, the system can accurately identify allergens regardless of their size, thus improving detection accuracy while maintaining a relatively simple detection process through optical parameter measurement.
2Loss of information
If wrong allergen information is provided to users, then user awareness is reduced, but providing accurate detection requires complex measurement systems
Solution Approach 1:
The patent replaces complex multi-parameter measurement systems with a relatively simple optical detection system using light sources and photodetectors. This substitution provides accurate allergen information by measuring light absorption characteristics, which are unique to different allergen substances, thereby reducing information loss without requiring overly complex device architecture.
Solution Approach 2:
The patent introduces light as an intermediary to transfer information about allergen substances to the detection system. By measuring how allergens interact with light (absorption characteristics), the system can accurately identify and communicate allergen presence to users without direct contact or complex sampling, thus providing accurate information with moderate system complexity.
3Productivity
If real-time allergen detection is implemented, then cleaning efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic detection cycles where the light source and photodetector are activated at regular intervals during the cleaning process. This periodic action enables real-time allergen detection to maintain cleaning efficiency, while allowing energy-consuming components to remain inactive between measurement cycles, thus reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The patent integrates the optical detection system with the existing cleaning workflow, allowing allergen detection to occur continuously during normal cleaning operations without interrupting the cleaning process. The light-based detection requires minimal energy compared to other real-time detection methods, enabling continuous monitoring that improves cleaning efficiency while maintaining acceptable energy consumption levels.
