Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If nozzles are stored separately in boxes, drawers, or cabinets, then the water spray gun structure remains simple, but it becomes inconvenient to find and replace nozzles, and nozzles may be lost

Engineering Contradiction:

Improveconvenience of nozzle replacementVSAvoidstructure of water spray gun

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the nozzle storage function with the water spray gun body by integrating a storage cavity into the gun structure. The cavity is formed within the gun body and includes a storage cavity inlet that allows nozzles to be placed and stored directly on the gun, eliminating the need for separate storage locations and making nozzles always accessible during use.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple nozzle types are kept for different spray modes, then spray versatility is improved, but it becomes more difficult to manage and locate specific nozzles

Engineering Contradiction:

Improvewater spray modesVSAvoidlocation of nozzles

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the storage space into multiple storage cavities, with each cavity designed to accommodate a specific nozzle type. This segmentation allows for organized storage of different nozzle types (e.g., for jet spray, column spray, fan spray, and scattering spray modes), making it easy to locate and access the required nozzle for each spray mode without mixing or confusion.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If nozzles are frequently removed and replaced, then spray mode flexibility is improved, but the risk of losing nozzles increases

Engineering Contradiction:

Improvenozzle replacement flexibilityVSAvoidnozzle retention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the storage and retrieval functions directly into the water spray gun body. The storage cavity is integrated into the gun structure with an inlet that allows nozzles to be easily placed and secured. This integration ensures that nozzles are always with the gun and cannot be lost, while still allowing frequent replacement when needed.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A gardening water spray gun with a replaceable sprinkler head including a water spray barrel, a sprinkler head, and a plurality of nozzles of different types. Two ends of the water spray barrel are formed a water inlet end and a water outlet end. One end of the sprinkler head is assembled on the water outlet end, and the other end of the sprinkler head forms a combination part to replaceably install the nozzle. A sleeve is provided at any position on the outer diameter of the water spray barrel. An arm extends from one side of the sleeve, and a combined seat is provided at the end of the arm. A joint part is formed at both the upper and lower ends of the combined seat for the nozzle to be coupled and positioned.
