Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of electronic nose is used, then operational flexibility is maintained, but inspection process complexity increases and time consumption increases
Solution Approach 1:
The system enables automatic inspection where the electronic nose autonomously positions itself to sampling points using the adjusting mechanism, eliminating the need for manual operation while maintaining operational effectiveness through automated control
Solution Approach 2:
The patent replaces manual mechanical operation with an automated adjusting mechanism that uses laser sensing for positioning, substituting human-operated mechanical systems with automated electromechanical systems
2Adaptability or versatility
If manual insertion of electronic nose sampler into container door is performed, then odor inspection of enclosed devices is achieved, but sampler damage risk increases and inspection time increases
Solution Approach 1:
The adjusting mechanism acts as an intermediary between the electronic nose and the container, providing controlled, precise positioning that reduces mechanical stress and damage risk to the sampler while enabling access to enclosed spaces
Solution Approach 2:
The laser sensing unit performs preliminary scanning to identify sampling points before the electronic nose is positioned, allowing pre-planning of the inspection path to avoid abrupt movements that could damage the sampler
3Measurement precision
If traditional inspection methods are used, then comprehensive odor detection is achieved, but inspection time increases
Solution Approach 1:
The laser sensing unit provides real-time feedback on the position of the electronic nose relative to sampling points, enabling dynamic adjustment and optimization of the inspection path to maintain detection accuracy while reducing inspection time
Solution Approach 2:
The adjusting mechanism dynamically positions the electronic nose during inspection based on real-time positioning data, allowing adaptive optimization of the inspection process to maintain comprehensive detection while minimizing time consumption
