Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing descaling mechanisms for liquid outlet devices face issues such as high processing accuracy requirements, dependence on water pressure, and limitations in removing scale without affecting liquid output or spray patterns, leading to incomplete descaling and reduced performance.
Innovation Solution
A descaling mechanism with a driving mechanism that moves relative to the liquid outlet unit, utilizing elastic elements and driving members to elastically deform and remove scale, allowing for flexible deformation without strict size or shape restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle is used to push out scale in the liquid outlet nozzle, then scale can be removed, but the needle must maintain a strict gap with the nozzle wall to avoid being wrapped, resulting in high processing accuracy requirements and incomplete scale removal
Solution Approach 1:
The patent extracts the descaling function from a rigid needle structure and transfers it to a flexible elastic element. The elastic element is inserted into the liquid outlet nozzle, and when liquid pressure acts on it, the element deforms to push out scale. This extraction allows the descaling mechanism to adapt to the nozzle interior without requiring precise dimensional control, as the elastic element can deform to match the nozzle's internal geometry.
Solution Approach 2:
The patent changes the physical state of the descaling element from rigid (needle) to elastic (deformable). The elastic element's ability to change its shape and size in response to liquid pressure allows it to effectively push out scale while adapting to variations in nozzle dimensions, thereby eliminating the need for strict processing accuracy.
2Reliability
If water pressure is used to deform an elastic element for descaling, then scale can be broken and removed, but the descaling effect highly depends on water pressure, and when water pressure is insufficient, the elastic element cannot be sufficiently deformed to achieve descaling
Solution Approach 1:
The elastic element is designed to be self-activating through the liquid pressure that naturally flows through the device. When liquid enters the liquid outlet nozzle, the pressure automatically deforms the elastic element, which in turn pushes out scale. This self-service mechanism eliminates the need for external actuators or additional energy input, making the descaling function inherently tied to the normal operation of the device.
Solution Approach 2:
The elastic element serves as an intermediary between the liquid pressure and the scale. Instead of liquid pressure directly removing scale (which may be ineffective), the elastic element mediates by deforming under pressure and mechanically pushing out the scale. This intermediary approach allows for more effective scale removal while reducing dependence on extreme pressure conditions.
3Reliability
If the number of liquid outlet nozzles is reduced to ensure sufficient water pressure for descaling, then the elastic element can be deformed effectively, but the liquid output amount decreases and spray pattern is affected
Solution Approach 1:
The patent segments the liquid outlet into multiple nozzles, each equipped with its own elastic element. This segmentation allows each nozzle to independently perform descaling functions while maintaining overall high liquid output. The modular approach ensures that sufficient liquid pressure is available at each nozzle for effective scale removal without reducing the total number of nozzles, thereby preserving both productivity and descaling effectiveness.
