Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garden hose nozzles can only change the shape of water spray through rotating nozzle heads, limiting the number of controllable shapes and not providing sufficient control over water output.
Innovation Solution
A garden hose nozzle structure that includes a hose nozzle body, a water guide base, a sprinkler cover, and a drainage plate, allowing for the creation of inner ring mist, outer ring mist, and various spray shapes through the rotation of the sprinkler cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nozzle head is rotated to change spray shape, then the spray shape can be adjusted, but the number of controllable shapes remains insufficient
Solution Approach 1:
The nozzle is divided into multiple functional components: an inner ring spray component with multiple spray holes and an outer ring spray component with multiple spray holes. Each ring can independently control spray output, allowing for multiple spray patterns (inner ring only, outer ring only, or both combined) without requiring multiple complete nozzle heads. This segmentation enables versatile spray shape control while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention transitions from a single-dimension rotation mechanism to a two-dimensional control system by adding the inner and outer ring structure. The spray control is no longer limited to rotating a single nozzle head but can independently adjust the inner ring and outer ring spray components, effectively adding another dimension of control freedom to achieve more spray shapes.
2Ease of operation
If a single nozzle head is used, then the structure is simple, but the control over water output is insufficient
Solution Approach 1:
The water output control is segmented into two independent control mechanisms: one for the inner ring spray component and another for the outer ring spray component. This allows users to independently adjust the water output from each ring, providing fine-grained control over total water output and spray distribution without requiring a complex multi-nozzle system.
3Area of stationary object
If water flow is increased to cover more area, then the spraying area increases, but plants may be damaged by excessive water flow
Solution Approach 1:
The spray system is divided into inner ring and outer ring components that can operate independently or in combination. This segmentation allows the spraying area to be expanded by activating both rings while maintaining control over water flow intensity. Users can adjust each ring's output separately to achieve broader coverage without concentrating excessive water flow in any single location, thereby reducing the risk of plant damage.
Solution Approach 2:
The inner ring and outer ring spray components provide different local spray characteristics. The inner ring can target central areas with controlled flow while the outer ring covers peripheral areas. This local quality differentiation allows the system to expand spraying area while distributing water flow more evenly across the target area, preventing any single location from receiving excessive water that could damage plants.
