Solution Overview

Problem

Existing garden watering systems require manual operation of manual ball valves, necessitating users to walk back and forth between their houses and gardens, which is inefficient and inconvenient.

Innovation Solution

A watering control system comprising a transmitter and receiver with processing units, wireless communication circuits, and control valves, enabling remote control of watering operations using identification codes for precise and automated management of multiple sprinkler heads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual ball valves are used for garden watering, then the system is simple and easy to manufacture, but it requires manual operation and causes loss of time due to users walking back and forth between house and garden

Engineering Contradiction:

Improvemanual operation convenienceVSAvoidtime for walking back and forth

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical valve operation with an automated electronic control system. A controller receives triggering signals (e.g., from sensors or remote devices) and automatically activates solenoid valves to control water flow, eliminating the need for manual intervention and repeated walking between house and garden.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The watering system is designed to operate autonomously by detecting watering conditions through sensors (e.g., soil moisture sensors) and automatically activating the appropriate valves. The system serves itself by making decisions about when and where to water without human intervention, thereby eliminating time loss from manual operations.

Inventive Principle:

Principle #25Self-service

2Device complexity

If multiple sprinkler heads are controlled by manual ball valves, then the device complexity is low, but the ease of operation deteriorates due to the need to manually control multiple valves

Engineering Contradiction:

Improvevalve control system complexityVSAvoidoperation of multiple valves

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent replaces multiple manual ball valves with an electronically controlled valve system. Each sprinkler head or zone is controlled by an electrically actuated valve that receives commands from a central controller, allowing a single user interface to manage multiple zones without the complexity of manual valve operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The controller serves multiple functions by being able to address and control multiple different valves through a single device. The system can selectively activate any combination of sprinkler heads or zones based on programmed schedules or sensor inputs, providing universal control over the entire irrigation network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of time

If automated control systems are implemented, then the loss of time is reduced, but the device complexity increases due to additional electronic components

Engineering Contradiction:

Improvemanual operation timeVSAvoidcontrol system complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces electronic control components (controllers, solenoid valves, sensors) to replace manual mechanical systems. This substitution automates the watering process, eliminating time loss from manual operations while managing complexity through integrated control logic and standardized components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If wireless communication is used for remote control, then the ease of operation is improved, but the use of energy increases due to wireless transmitting and receiving circuits

Engineering Contradiction:

Improveremote control convenienceVSAvoidenergy consumption of wireless circuits

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The wireless communication system operates periodically rather than continuously. The transmitter sends control signals at specific intervals or triggered events, and the receiver processes these periodic signals to activate valves. This periodic operation significantly reduces energy consumption compared to continuous communication while maintaining remote control functionality.

Inventive Principle:

Principle #19Periodic action
