Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispensing additives into water streams, such as showers or toilets, lack precise control over the dispensing rate and volume, leading to inconsistent results and difficulties in switching between additives during use.
Innovation Solution
A dosing apparatus with a damping control system that uses a hydraulic piston and sprung damping chamber to control the dispensing rate, allowing adjustable dispensing over a set time period, combined with a removable adapter for standard essential oil bottles that assists in minimizing waste and facilitating easy switching between additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dispensing rate is controlled by water flow rate, then the system is simple, but the dispensing precision and consistency deteriorate
Solution Approach 1:
A damping chamber is introduced as an intermediary component between the additive container and the water stream. This damping chamber receives the additive and controls its release rate independently of water flow variations, thereby mediating between the simple container design and the need for precise dispensing control
Solution Approach 2:
The system uses hydraulic principles through the damping chamber, which utilizes fluid pressure and flow characteristics to regulate the dispensing rate. The damping chamber creates a controlled hydraulic environment that maintains consistent additive delivery regardless of external water pressure fluctuations
2Speed
If the dispensing rate is increased to meet user demand, then the responsiveness improves, but the additive container depletes faster
Solution Approach 1:
The damping chamber provides dynamic control over the dispensing rate, allowing the system to adapt between rapid dispensing when demand is high and slower dispensing when demand is low. This dynamic adjustment capability enables responsive service while optimizing additive consumption based on actual usage patterns
Solution Approach 2:
The system changes the dispensing parameter (rate) based on demand conditions. The damping chamber allows the dispensing rate to be adjusted as a variable parameter rather than being fixed, enabling the system to optimize between speed of service and conservation of additive resources
3Ease of manufacture
If a fixed dosing mechanism is used, then the manufacturing cost is reduced, but the adaptability to different additives deteriorates
Solution Approach 1:
The damping chamber serves multiple functions: it acts as a metering device, a mixing chamber, and a flow regulator. This multi-functionality allows a single simple component to handle various additive types and dispensing requirements, providing versatility without increasing manufacturing complexity
Solution Approach 2:
The system segments the dispensing function into two independent parts: the additive container and the damping chamber. This segmentation allows the container to be simple and inexpensive while the damping chamber provides the necessary control and adaptability for different additives

Implementation Method 1
a hydraulic piston within a charging chamber containing hydraulic fluid, wherein the hydraulic piston is arranged to be driven so as to move a quantity of hydraulic fluid from the hydraulic charging chamber and through a second one-way valve and to a sprung damping chamber
Implementation Method 2
a sprung damping chamber arranged to absorb the volume of the displaced hydraulic fluid while creating a spring force to complete a return cycle of the dosing mechanism
Implementation Method 3
a damping control system arranged to control a dispensing rate of the set volume of the liquid
Implementation Method 4
a return channel across the second one-way valve, wherein the return channel is arranged to limit the rate at which the hydraulic fluid can pass therethrough
