Multi-Container Spray Dispenser with 360 Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol dispensing systems are limited in their ability to handle multiple products, often leading to fragrance fatigue, wasteful dispensing, and frequent refilling due to lack of user detection and inefficient motion sensing, as well as difficulties in loading and positioning aerosol containers and batteries.
Innovation Solution
A dispensing system with a housing that can accommodate multiple aerosol containers, featuring a motion detection system with a 360-degree field of view and alternating active and lockout modes for product release, along with an actuator drive system for selective product dispensing and improved container and battery placement mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single product container is used in the dispensing system, then the device complexity is reduced, but the adaptability deteriorates because the system cannot dispense multiple products
Solution Approach 1:
The dispensing system is segmented into multiple independent product containers (first container, second container), each capable of being dispensed separately. This allows the system to handle multiple products while maintaining modular simplicity, as each container operates independently with its own actuation mechanism.
Solution Approach 2:
The housing and actuator system are designed with universal functionality to accommodate and dispense from multiple different container types. The single actuator can selectively activate different containers, making the system adaptable to various products without requiring separate dispensing mechanisms for each.
2Ease of operation
If motion detection is used to trigger dispensing, then the ease of operation is improved, but loss of substance increases due to wasteful dispensing when users are not present
Solution Approach 1:
The system incorporates motion detection feedback to monitor user presence and automatically control dispensing operations. When motion is detected, the system activates the appropriate container; when no motion is detected, dispensing is automatically stopped, preventing wasteful product release and ensuring operation only when needed.
3Measurement precision
If a single motion sensor is used, then the device complexity is reduced, but measurement precision deteriorates due to limited field of vision
Solution Approach 1:
Multiple motion sensors are merged into a coordinated detection system, with their fields of vision overlapping to provide comprehensive coverage. This combination enhances measurement precision by ensuring reliable user presence detection from multiple angles, reducing blind spots while maintaining manageable system complexity through integrated control.

AI summary
A spray dispenser includes a housing for placement in a space. The housing is adapted to receive at least one container having a material therein for emission into the space in response to at least one of a timer, manual actuation and sensory input. The spray dispenser further includes at least three sensors distributed around a perimeter of the housing for the detection of sensory input.
