Solution Overview

Problem

Autonomous work vehicles, such as agricultural tractors, face challenges in efficiently transitioning between autonomous and manual operation modes, with existing systems often requiring significant space for operator controls that interfere with autonomous functions and lack flexibility in deployment.

Innovation Solution

The design incorporates a stowable operator station within the vehicle body, featuring a deployable seat and steering wheel mount that can be stowed during autonomous operation and deployed for manual control, allowing the operator station to be partially external to the vehicle body, minimizing space usage and interference with autonomous functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operator station is permanently installed within the vehicle body, then the operator can control the vehicle manually, but the vehicle body requires significant space that interferes with autonomous operation and overall vehicle efficiency

Engineering Contradiction:
Improvemanual control capabilityVSAvoidvehicle body space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The operator station is designed as a dynamic, deployable structure that can transition between stowed and deployed positions. The seat assembly includes a base positioned within the vehicle body and a seat portion that extends outward, allowing the operator station to occupy space only when manually deployed, thereby resolving the contradiction between manual control capability and vehicle body space utilization

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The operator station is nested within the vehicle body when not in use. The seat base is positioned inside the vehicle body, and the seat portion can be folded or retracted into a stowed position within the vehicle body, allowing the control system to be contained within the vehicle body volume while still providing external access when needed

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the operator station is deployed externally for manual control, then the operator has adequate control capability, but the transition between autonomous and manual modes becomes complex and time-consuming

Engineering Contradiction:
Improvemanual control capabilityVSAvoiddeployment mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The operator station is segmented into distinct functional components: a base assembly positioned within the vehicle body, a seat portion that extends outward, and integrated control elements. This segmentation allows each component to be independently positioned and configured, simplifying the deployment mechanism while maintaining full manual control capability when extended

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The operator station base serves multiple functions: it provides structural support for the seat, houses control systems, and acts as a mounting point for various operational controls. This multi-functionality reduces the overall complexity of the deployment mechanism by consolidating multiple functions into a single integrated base structure

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the operator station components are permanently positioned, then the vehicle structure is simpler, but the vehicle lacks flexibility to switch between autonomous and manual operation modes efficiently

Engineering Contradiction:
Improveoperation mode flexibilityVSAvoidvehicle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle structure incorporates dynamic elements that allow the operator station to transition between stowed and deployed positions. The seat assembly includes movable joints and positioning mechanisms that enable the operator station to be configured for manual operation when needed while maintaining a streamlined profile for autonomous operation, providing operational mode flexibility without excessive structural complexity

Inventive Principle:
Principle #15Dynamics
