Solution Overview

Problem

Existing camera mounting systems for agricultural equipment are not optimally designed for specific implements, leading to suboptimal visualization and control of working processes, as they are typically mounted on tractors rather than the implements themselves.

Innovation Solution

A camera mounting system for drawn agricultural implements that includes a main frame with ground-engaging units, a working unit for engaging crops, and a sensor supported from a draft tongue, allowing for adjustable positioning and orientation of the sensor's field of view via actuators and controllers, enabling optimal visualization regardless of the implement's orientation or position relative to the tractor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sensor is mounted on the tractor, then the sensor is stable and easy to control, but the field of view cannot be optimized for specific implement working positions

Engineering Contradiction:
Improvefield of view optimization for implement positionsVSAvoidsensor mounting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor is mounted on the implement rather than the tractor, allowing it to move dynamically with the implement and maintain optimal positioning relative to the working units. The sensor mount includes actuators that enable real-time adjustment of the sensor's position and orientation based on implement configuration and working conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sensor mounting system is divided into separate functional components: the sensor itself, the sensor mount with actuators, the controller, and the communication interface with the implement controller. This segmentation allows each component to be optimized independently and simplifies the overall system architecture.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the sensor is mounted on the implement, then the field of view can be optimized for working units, but the sensor positioning must adapt to implement orientation changes

Engineering Contradiction:
Improvevisualization accuracy of working processVSAvoidadaptability to implement orientation
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The sensor mount includes actuators controlled by a controller that receives signals from the implement controller. This feedback loop allows the sensor position and orientation to be automatically adjusted in response to implement orientation changes, ensuring continuous optimization of the field of view for the working units.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The sensor mounting system is designed to be dynamically adjustable, with actuators that can reposition the sensor in real-time as the implement orientation changes during operation, maintaining optimal visualization conditions throughout the working cycle.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the sensor field of view is fixed relative to the draft tongue, then the mounting is simple, but the field of view cannot be adjusted for different working conditions

Engineering Contradiction:
Improvefield of view adjustment capabilityVSAvoidsensor support mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor is mounted on an adjustable support mechanism that includes actuators enabling dynamic repositioning of the sensor. This allows the field of view to be adjusted for different working conditions and implement configurations while maintaining a relatively simple overall mounting structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sensor mounting system is designed to accommodate multiple working conditions and implement types through its adjustable mechanism. The same mounting system can optimize the field of view for different implement orientations and working unit positions, providing universal adaptability.

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

AI summary

A drawn agricultural implement (10) includes a main frame and a plurality of ground engaging units supporting the main frame from a ground surface. A working unit is supported from the main frame and configured to engage crops (37) as the implement moves in a forward direction across the ground surface. A draft tongue (44) extends from the main frame for attachment to a tractor (26). A camera (46) having a field of view is mounted on at least one of the draft tongue, the main frame and the working unit. The camera is movable relative to the at least one of the draft tongue (44), the main frame and the working unit to reposition the field of view.
