Solution Overview
Problem
Current systems lack the precision and efficiency for users to create, test, and refine perfume recipes, particularly in small quantities, and do not allow for easy storage or scaling of custom scent blends.
Innovation Solution
A scent dispensing device with multiple containers and a precise dispensing system, driven by an electric motor and encoder, allows for accurate dispensing of scent ingredients onto a single medium, enabling users to create and modify recipes, store them, and scale to larger volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual dispensing methods are used, then device complexity is reduced, but manufacturing precision and dispensing accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical dispensing with an automated electromechanical system featuring an electric motor, gearhead, and encoder for precise control. This substitution enables accurate dispensing quantities (e.g., 1-5 drops) while maintaining manageable device complexity through modular architecture and integrated control.
Solution Approach 2:
The system incorporates automatic dispensing control where the motor and encoder automatically regulate the dispensing process based on pre-programmed parameters. The system self-regulates the number of drops dispensed without requiring manual intervention, improving precision while reducing operational complexity.
2Productivity
If large quantities of scent ingredients are dispensed, then productivity is improved, but loss of substance increases
Solution Approach 1:
The system dispenses only the necessary partial quantity of scent ingredients required for each perfume formulation rather than dispensing large amounts. By controlling the exact number of drops (e.g., 1-5 drops per ingredient), the system maintains productivity while minimizing substance loss and waste.
Solution Approach 2:
The patent implements adjustable dispensing parameters including the number of drops per ingredient, selection of scent ingredients, and formulation ratios. These parameter changes enable optimized dispensing quantities that balance productivity requirements with minimal ingredient waste, allowing users to adjust based on specific formulation needs.
3Manufacturing precision
If multiple scent ingredients are dispensed separately, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the dispensing system into separate containers and dispensing mechanisms for each scent ingredient. This segmentation allows independent control and precise dispensing of each ingredient while maintaining manageable complexity through modular design, where each container-unit can be independently managed and replaced.
Solution Approach 2:
The system employs a universal dispensing mechanism that can handle multiple different scent ingredients through the same basic dispensing architecture. The electric motor, gearhead, and encoder system serves as a multi-functional platform that can accurately dispense various ingredients, reducing overall complexity compared to having separate specialized mechanisms for each ingredient.
4Manufacturing precision
If precise control of dispensing quantity is implemented, then manufacturing precision is improved, but use of energy increases
Solution Approach 1:
The patent uses an electric motor with encoder feedback to replace simpler mechanical dispensing mechanisms. While this increases energy consumption compared to passive mechanical systems, it enables precise control of dispensing quantities through electronic control, achieving the required manufacturing precision for perfume formulation.
Solution Approach 2:
The motor-controlled dispensing system automatically regulates its own operation based on pre-programmed parameters and encoder feedback. This self-regulating capability maintains precise dispensing control while optimizing energy usage by activating the motor only when dispensing is required and stopping precisely when the target quantity is reached, minimizing unnecessary energy consumption.

AI summary
A scent dispensing device is provided that includes a plurality of containers, each containing a different scent ingredient; a driving system configured to separately cause each of the plurality of containers to dispense a quantity of the respective scent ingredient; and a delivery system configured to transport any dispensed quantities from the scent containers to a common receiving area for dispensing onto to a single medium.
