Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If olfactory displays generate and provide vaporized odor molecules to an environment, then smell perception is achieved, but precise control over the release of odor molecules is lacking
Solution Approach 1:
The patent employs parameter changes by utilizing temperature adjustment to control the release rate of chemical substances. The heating element increases temperature to enhance vaporization and release, while the cooling element decreases temperature to reduce release. This allows precise control over the odor molecule release parameters without adding complex mechanical control systems.
Solution Approach 2:
The patent replaces complex mechanical valve systems with a thermal control mechanism. Instead of using mechanical components to precisely control release, the invention uses heating and cooling elements to modulate the physical state and release rate of chemical substances, simplifying the device while achieving precise control.
2Adaptability or versatility
If olfactory displays are designed for stationary use, then functionality is maintained, but portability and wearable applications are limited
Solution Approach 1:
The patent employs a flexible housing that can be bent and deformed without breaking. This flexible shell maintains the structural integrity of the device while enabling portability and wearable applications. The flexible housing protects internal components while allowing the device to conform to different shapes and positions.
3Ease of operation
If chemical substances are released continuously, then smell perception is maintained, but precise odor management and user experience are reduced
Solution Approach 1:
The patent implements periodic action through alternating heating and cooling cycles. The heating element operates intermittently to vaporize chemical substances when odor release is needed, followed by cooling periods to reduce release. This periodic operation enables precise odor management while reducing continuous energy consumption compared to constant heating.
