Solution Overview

Problem

Conventional route setting methods for autonomous work vehicles are unable to adapt turning methods based on the specific position within a field, leading to inefficiencies in work efficiency and safety.

Innovation Solution

A route setting method that allows for the selection and adaptation of different turning routes for each work path within a field, enabling the work vehicle to adjust its turning method according to the field's conditions and user needs by setting a predetermined turning route among multiple options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a uniform turning method is set for the entire field, then the route setting system is simple and easy to operate, but it cannot adapt to different positions in the field, reducing work efficiency and safety

Engineering Contradiction:
Improveroute setting simplicityVSAvoidwork efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The field is divided into multiple work paths, and each work path can have its own turning method settings. This segmentation allows different turning methods to be applied to different positions in the field, optimizing work efficiency for each specific area while maintaining overall system manageability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different turning methods are assigned to different work paths based on local field conditions and user needs. Each work path can have customized turning route settings, allowing the system to adapt to local requirements rather than applying a one-size-fits-all approach

Inventive Principle:
Principle #3Local quality

2Device complexity

If a uniform turning method is set for the entire field, then the system configuration is straightforward, but it cannot respond to user needs based on specific field conditions

Engineering Contradiction:
Improvesystem configuration complexityVSAvoidturning method adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The turning route setting is segmented by work path, allowing each path to have independent turning method configurations. This maintains reasonable system complexity while significantly improving adaptability to different field conditions and user requirements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic selection of turning methods for each work path, enabling users to adjust turning routes based on specific field conditions, work requirements, and safety considerations for each area

Inventive Principle:
Principle #15Dynamics

3Productivity

If position-specific turning methods are implemented for each work path, then work efficiency and user needs are better met, but the route setting system becomes more complex

Engineering Contradiction:
Improvework efficiencyVSAvoidroute setting system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments turning route settings by work path, which organizes the complexity into manageable units. Each work path can be configured independently, making the overall complex system more controllable and easier to manage through modular configuration

Inventive Principle:
Principle #1Segmentation
