Solution Overview

Problem

Existing irrigation systems for precision agriculture are complex in design, requiring extensive irrigation pipes and valves for individual zone control, which complicates assembly and maintenance, especially when accessing cultivated land.

Innovation Solution

An irrigation system with zones arranged in columns and control heads located along the boundary, allowing independent control and distribution of irrigation substances through a main distribution pipe, enabling precise irrigation scheduling based on sensor data without transverse piping within the field, facilitating easier maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual zone control with extensive irrigation pipes and valves is implemented, then precise irrigation scheduling for each zone is achieved, but system complexity and difficulty of assembly and maintenance increase

Engineering Contradiction:
Improveprecise irrigation schedulingVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The field is divided into multiple zones that can be independently controlled. Each zone receives irrigation based on its specific needs determined by sensor data, allowing precise irrigation scheduling without requiring complex individual control for every area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Control heads are centralized and located outside the cultivated field area. Multiple irrigation lines share common infrastructure including the main distribution pipe and control equipment, reducing overall system complexity while maintaining zone-specific irrigation capabilities.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If control infrastructure is placed within the field for zone control, then individual zone management is enabled, but access difficulty and maintenance complexity increase

Engineering Contradiction:
Improveindividual zone managementVSAvoidmaintenance accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

Control heads and other control infrastructure are extracted from the cultivated field area and positioned outside. This allows farmers to access and maintain control equipment without entering or disrupting the cultivated zones, significantly improving maintenance accessibility while preserving individual zone management capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Irrigation lines are routed through intermediate areas or along field boundaries rather than directly through cultivated zones. This intermediary routing allows control infrastructure to be positioned in accessible locations while still delivering water to individual zones within the field.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If transverse piping is installed within the field for zone distribution, then comprehensive zone coverage is achieved, but assembly complexity and field access difficulty increase

Engineering Contradiction:
Improvezone coverageVSAvoidassembly complexity
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

Instead of installing pipes in multiple directions including transverse routes through the field, the system uses irrigation lines that extend primarily in one dimension - from the boundary inward to each zone. This unidirectional approach simplifies assembly while achieving comprehensive coverage of all zones through the structured layout.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An irrigation system is provided for irrigating a field divided into zones. The zones are arranged in columns extending alongside each other. The system has irrigation strips and a control head at an upstream end of each irrigation strip. Each irrigation strip provides irrigation substances to a column of zones and all control heads are located alongside a boundary of the field.
