User-Size Sensing Sanitizer Dispensing for Precise Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems lack the ability to accurately dispense sanitizing materials based on the size of the user, leading to inefficient use of resources and potential over or under-dispensing.
Innovation Solution
A dispensing system equipped with a sensor assembly that detects the size of a user using multiple sensors positioned at different heights, allowing the system to activate the dispensing device to release a quantity of material corresponding to the user's size, thereby optimizing material distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed quantity of material is dispensed to all users, then the dispensing process is simple and quick, but the material usage efficiency deteriorates due to over-dispensing or under-dispensing
Solution Approach 1:
The dispensing system dynamically adjusts the material quantity based on real-time detection of user size. The sensor assembly continuously monitors user dimensions and the dispensing device modifies its output accordingly, transforming a static fixed-dose system into a dynamic adaptive system that optimizes both speed and material efficiency
Solution Approach 2:
The system changes the dispensing parameter (material quantity) based on detected user characteristics. By varying the dispensed amount according to user size parameters, the system achieves precise dosing that prevents both waste and insufficient dispensing while maintaining quick operation
2Measurement precision
If the dispensing system uses multiple sensors at different heights to detect user size, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The sensor assembly is segmented into multiple sensors positioned at different heights, each responsible for detecting specific portions of the user's body. This segmentation allows the system to build a comprehensive size profile by combining data from individual sensor positions, achieving high measurement precision through distributed detection
Solution Approach 2:
Multiple sensors serve the universal function of user size detection, with each sensor contributing to the overall measurement. The system uses these sensors to detect various body dimensions (height, width, depth) simultaneously, making the sensor assembly multi-functional in measuring different spatial parameters
3Loss of substance
If the dispensing system adjusts material quantity based on user size, then the resource utilization improves, but the system complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The dispensing system performs self-adjustment based on automatic user detection. The sensor assembly autonomously detects user size and the control system automatically modifies dispensing parameters without requiring manual intervention, enabling the system to serve itself in optimizing material usage while managing complexity through automation
