Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional sprinkling device is used, then the structure is simple, but the sprinkling effect is limited and cannot achieve uniform 360-degree coverage
Solution Approach 1:
The sprinkling device is segmented into multiple functional components: a water circulating member with internal passages, a water guide member with tapered surface, and multiple shunting members positioned equidistantly along the circumference. This segmentation allows each component to perform a specific function (water distribution, guidance, and directional control) to achieve uniform 360-degree sprinkling coverage while maintaining manufacturing feasibility through modular assembly
Solution Approach 2:
The invention transitions from conventional single-direction or limited-angle sprinkling to three-dimensional 360-degree coverage by arranging shunting members equidistantly along the circumferential direction of the water guide member. The tapered water guide surface directs water flow in multiple radial directions simultaneously, creating comprehensive spatial coverage that eliminates dead zones and achieves uniform distribution across all surfaces including door body, door seal, and clothes
2Area of stationary object
If water is sprayed in the form of a water column, then the spray area is limited, but the water consumption is higher
Solution Approach 1:
The invention utilizes hydraulic principles by designing a water circulating member with internal water circulating passages that distribute water to multiple shunting members. The tapered water guide surface converts water flow from vertical columnar discharge into radial sheet-like flow patterns, leveraging fluid dynamics to expand water coverage area while maintaining efficient water utilization through the integrated circulating passage system
3Loss of energy
If foam residue remains on door seal and door body, then detergent utilization rate decreases, but washing time increases
Solution Approach 1:
The sprinkling device performs preliminary washing action during the washing cycle by continuously circulating water through the door seal and door body surfaces. The uniform 360-degree sprinkling pattern ensures that foam residue is flushed away from detergent dissolution areas before it can interfere with subsequent washing operations, maintaining high detergent utilization rates and preventing the need for extended washing times to compensate for poor detergent efficiency
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 device improves detergent utilization, reduces washing time, and enhances washing effectiveness by ensuring uniform sprinkling, reducing foam residue, and simultaneous washing of the door body, door seal, and clothes.
Implementation Method 1
a water guide member, disposed below the water circulating member, and having a tapered water guide surface opposite the water outlet
Implementation Method 2
