Scent Emitter Concentration Control Using Sensory Perception Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent adjustment systems fail to dynamically adjust scent material concentrations based on individual sensory responses and environmental factors, leading to discomfort or ineffective scent delivery in indoor spaces.
Innovation Solution
A scent adjustment system comprising a scent emitter, a storage unit for sensory information associating smell intensity and concentration, and a controller that adjusts scent material concentration based on stored data, using a database to determine optimal concentrations for comfort, adaptive patterns, and desired functions in indoor spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed concentration of scent material is supplied, then device complexity is reduced, but adaptability to individual sensory responses and environmental factors deteriorates
Solution Approach 1:
The system performs preliminary actions by storing sensory information and concentration data in a database before actual scent delivery. The controller pre-processes this information to determine appropriate concentration levels, so when a scent material is selected, the adjustment parameters are already prepared, enabling rapid adaptation without complex real-time processing.
Solution Approach 2:
The controller acts as an intermediary between the stored sensory information and the scent emitter. It processes the relationship between smell intensity perceptions and actual concentrations, translating subjective sensory data into objective control parameters for the emitter, thereby bridging the gap between individual responses and mechanical delivery.
2Reliability
If fixed concentration of scent material is supplied, then ease of operation is improved, but effectiveness of scent delivery deteriorates
Solution Approach 1:
The system performs self-service by automatically adjusting scent concentration based on pre-stored sensory information without requiring manual intervention. The controller autonomously processes the relationship between smell intensity and concentration, and the emitter automatically delivers the appropriate amount, ensuring effective scent delivery while maintaining ease of operation.
Solution Approach 2:
The system incorporates feedback mechanisms by storing sensory information that reflects actual human perception of scent intensity. This feedback loop allows the controller to adjust concentrations based on perceived effectiveness, ensuring reliable scent delivery while the system operates autonomously without user intervention.
3Illumination intensity
If high concentration of scent material is supplied, then desired scent intensity is achieved, but discomfort to persons deteriorates
Solution Approach 1:
The system applies partial action by supplying scent material at concentrations that are sufficient to achieve the desired scent intensity perception but not excessive enough to cause discomfort. The controller calculates appropriate concentration levels based on stored sensory information, delivering only the necessary amount required for effective scent delivery without over-saturation.
Solution Approach 2:
The system changes parameters by adjusting scent material concentration based on stored sensory information and environmental factors. The controller modifies concentration parameters dynamically to maintain optimal scent intensity perception while avoiding discomfort, transforming fixed concentration delivery into adaptive parameter control.

AI summary
A scent adjustment system includes a scent emitter arranged to supply a scent material to a target space, a storage, and a controller. The storage stores sensory information in which an intensity of a smell of the scent material perceived by a person and a concentration of the scent material are associated with each other. The controller adjusts the concentration of the scent material supplied from the scent emitter based on the sensory information stored in the storage.
