Agricultural Display Unit Crab Steering Pivot Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display units for agricultural working machines are only suitable for simple machines and fail to effectively adapt to work machines with crab steering, leading to asymmetrical pivoting ranges and potential damage from over-tightening.
Innovation Solution
A display unit that visualizes the current pivoting angle and possible pivoting range of a swiveling adaptation device, taking into account the crab steering angle, with real-time updates and text-based representations to help drivers recognize safe pivoting directions, and automatically limits the crab angle when attachments are detected to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adaptation device is allowed to pivot freely with crab steering, then the working machine can operate in various directions, but the adaptation device may be over-tightened and damaged due to asymmetrical pivoting ranges
Solution Approach 1:
The display unit provides real-time feedback to the driver about the current pivoting angle and the available pivoting range in each direction. This feedback mechanism allows the driver to understand the asymmetrical constraints and avoid maneuvers that would cause over-tightening or damage to the adaptation device.
Solution Approach 2:
The system performs preliminary calculation of the available pivoting range based on the current crab steering angle before the driver executes a maneuver. By displaying the safe pivoting limits in advance, the system prevents dangerous operations rather than reacting after damage occurs.
2Ease of operation
If the display unit shows detailed pivoting information, then the driver can recognize safe directions, but the device complexity increases
Solution Approach 1:
The display information is segmented into distinct visual elements: the current pivoting angle indication, the available pivoting range in each direction, and the crab steering angle. This segmentation presents complex information in a structured, easy-to-understand format without overwhelming the driver.
Solution Approach 2:
The display unit acts as an intermediary between the complex sensor/actuator system and the driver. It translates raw sensor data about pivoting angles and mechanical constraints into intuitive visual representations that the driver can easily comprehend and act upon.
