Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a Venturi nozzle is used to suck soap out of a container, then soap and water can be mixed, but a continuously high flow rate of water is required leading to high water consumption
Solution Approach 1:
The patent employs a siphon mechanism (hydraulic principle) to extract cleaning liquid from the container using the water flow itself, eliminating the need for high continuous water flow rates. The siphon creates a pressure differential that automatically draws soap into the water stream, achieving effective mixing with reduced water consumption.
Solution Approach 2:
The siphon system is self-regulating and automatically controls the mixing process. Once activated, the siphon maintains itself through the water flow, automatically drawing in the required amount of cleaning liquid without needing continuous high-pressure water input, thus reducing overall water consumption while maintaining mixing productivity.
2Reliability
If complex mechanical constructions with moving parts are used to mix soap and water, then mixing can be achieved, but the device requires maintenance and has high wear
Solution Approach 1:
The patent replaces complex mechanical mixing systems with moving parts (gears, pistons, valves) with a passive hydraulic mixing system using a siphon and injector nozzle. This substitution eliminates mechanical wear and maintenance requirements while achieving effective soap-water mixing through fluid dynamics principles.
Solution Approach 2:
The invention extracts and utilizes the natural kinetic energy and pressure of the water flow to drive the mixing process through the siphon mechanism, removing the need for separate mechanical drive systems. This extraction of functional capability from mechanical components directly reduces maintenance needs.
3Use of energy by moving object
If high water flow rates are used for continuous mixing, then sufficient negative pressure is generated for mixing, but energy consumption increases
Solution Approach 1:
The patent changes the operational parameters of the water flow by using the siphon mechanism to create localized pressure differentials at specific points in the system. This allows effective mixing to occur with lower overall water flow rates, thereby reducing the energy required to maintain the water supply while preserving mixing capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces water consumption, enhances energy efficiency, and allows for easy removal of cleaning liquid and water mixtures, including foamed solutions, while maintaining low wear and maintenance, ensuring efficient operation.
Implementation Method 1
a siphon, wherein the container is fluidly connected to the fluid-conducting element via the siphon
Implementation Method 2
A disadvantage of this device is that a continuously high flow rate of the water is required for a continuous mixing of the water with the soap or the shampoo in order to generate a sufficiently high negative pressure
