Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sprinkler systems provide restricted coverage, necessitating manual relocation, leading to uneven watering and inconvenience, and can result in patchy grass growth due to inconsistent water distribution.

Innovation Solution

A rotating sprinkler device with a movable track that allows the sprinkler head to be easily repositioned along a sliding track, enabling even lawn coverage by allowing the sprinkler head to be moved within the base without relocating the entire device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sprinkler head is fixed in position, then the device structure is simple, but the coverage area is restricted and requires manual relocation

Engineering Contradiction:

Improvecoverage areaVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sprinkler head is made movable along the track rather than fixed, allowing dynamic repositioning to cover different areas. The track system enables the sprinkler head to move between positions while the base remains stationary, providing adaptability without requiring complete device relocation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device is divided into separate functional components: a stationary base with water supply, a movable track system, and a repositionable sprinkler head. This segmentation allows the sprinkler head to be independently moved along the track to cover different areas without moving the entire device.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the entire sprinkler device is relocated manually, then coverage can be changed, but the process is tedious and inconvenient

Engineering Contradiction:

Improveposition coverageVSAvoidrepositioning convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of moving the entire heavy device, only the lightweight sprinkler head moves along the track. This dynamic repositioning mechanism eliminates the need to drag hoses and relocate the entire sprinkler system, making operation much more convenient.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The sprinkler head is extracted from the main device body and placed on a separate movable track system. This allows the sprinkler head to be repositioned independently without moving the base and hose connection, eliminating the inconvenience of relocating the entire device.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the sprinkler head is frequently moved, then coverage can be adjusted, but the risk of getting clothes and footwear wet increases

Engineering Contradiction:

Improvecoverage adjustmentVSAvoidwater spillage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The sprinkler head moves dynamically along the track during operation, allowing coverage adjustment without requiring the user to manually handle the hose or relocate the entire device. This eliminates the risk of water spillage on clothes and footwear that would occur during manual relocation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The track system enables the sprinkler head to reposition itself or be easily repositioned without requiring user intervention to move the entire device. The system serves itself by providing a built-in repositioning mechanism that eliminates the need for manual handling and associated water spillage risks.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If manual relocation is not performed consistently, then convenience is maintained, but uneven watering and patchy grass growth occur

Engineering Contradiction:

Improveoperation consistencyVSAvoidwatering uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The movable track system enables consistent repositioning of the sprinkler head to different locations. By making the track system accessible and easy to use, users can reliably move the sprinkler head to ensure uniform coverage across the entire lawn, eliminating patchy growth caused by inconsistent watering.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The track system is pre-installed with multiple positions marked or designated for optimal coverage. Users can refer to these pre-planned positions to ensure consistent and uniform watering patterns, eliminating the need to remember random locations and ensuring even grass growth.

Inventive Principle:

Principle #10Preliminary action

AI summary

A rotating sprinkler device with movable track is provided. The device is comprised of a base with a hose connection point, a tubing, and a track to which at least one rotating sprinkler head is attached. As user can connect a hose to the base with the connection point to supply water to the sprinkler head. The sprinkler head can then be slid along the track in order to move the position of the sprinkler head, without moving the base, to water various areas surrounding the device.
