Solution Overview
Problem
Existing sanitation, cosmetics, and cleaning facilities lack advanced automation and user-friendliness, leading to inefficiencies in water usage and consumable distribution, particularly in low flow-rate applications where consumables are rinsed away quickly, resulting in reduced effectiveness and increased consumption.
Innovation Solution
A facility with a low through-flow rate water supply system integrated with a consumable unit and a closed-loop control unit that measures and adjusts operation parameters, allowing for precise mixing and dispensing of consumables, such as body care products or cleaning agents, based on flow rate, user input, and cycle modes, while also enabling remote monitoring and data analysis for optimized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a low through-flow rate is used to reduce water consumption, then water efficiency is improved, but the consumable is rinsed away quickly reducing cleaning effectiveness
Solution Approach 1:
The system uses sensors to detect when the user has finished washing and automatically adjusts the flow rate accordingly. During the washing phase, a higher flow rate ensures effective cleaning, while after detection of washing completion, the flow rate is reduced to conserve water. This feedback mechanism resolves the contradiction by dynamically adjusting water flow based on actual need rather than maintaining a consistently low flow rate.
Solution Approach 2:
The facility dynamically changes its operation mode between a first mode (higher flow rate) during active washing and a second mode (lower flow rate) after washing completion. This dynamic adjustment allows the system to provide sufficient water flow when needed for effective cleaning while minimizing water consumption during idle periods, thereby resolving the contradiction between cleaning effectiveness and water efficiency.
2Ease of operation
If automation is increased to improve user-friendliness and efficiency, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The facility is equipped with sensors that automatically detect user presence and washing completion, eliminating the need for manual operation. The system self-adjusts water flow rates and consumable dispensing based on detected user actions, providing hands-free operation. This self-service capability improves ease of operation while keeping the automation complexity manageable by using simple detection mechanisms rather than complex control systems.
Solution Approach 2:
Manual mechanical controls are replaced with sensor-based detection systems that automatically sense user presence and washing completion. This substitution uses optical or capacitive sensors combined with electronic control to replace what would otherwise require manual mechanical intervention, improving ease of operation while maintaining relatively simple device architecture through the use of standard sensor technologies.
