Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user relies on direct visual observation only, then the system remains simple, but the user cannot accurately position the implement when it is not directly visible
Solution Approach 1:
The patent introduces a camera as an intermediary device mounted on the implement to capture visual information from perspectives not visible to the user. The camera feeds real-time images to a display system, enabling the user to see the implement's position and surroundings even when blocked from direct view, thus resolving the contradiction between positioning accuracy and system simplicity.
Solution Approach 2:
The system adds a visual information dimension by mounting cameras on the implement to capture images from multiple angles and perspectives. This dimensional expansion of information availability allows the user to mentally construct a comprehensive view of the implement's position and trajectory, improving positioning accuracy without requiring physical presence at multiple locations.
2Measurement precision
If a user has assistance from a colleague or camera, then visibility is improved, but the user still cannot accurately predict future implement position without experience
Solution Approach 1:
The system performs preliminary computational action by using the processor to calculate and predict the implement's future position based on current position data, machine movement parameters, and implement configuration. This predicted future position is displayed to the user in advance, allowing them to plan control inputs without requiring extensive experience to mentally simulate the implement's trajectory.
Solution Approach 2:
The system provides continuous feedback by displaying the predicted future position of the implement alongside real-time camera images. This feedback loop allows the user to compare the predicted trajectory with the desired position and make real-time adjustments to control inputs, reducing the operational difficulty and improving prediction accuracy even for inexperienced users.
3Loss of information
If the system displays only current implement position, then the display remains simple, but the user cannot make informed decisions about future positioning
Solution Approach 1:
The patent merges multiple information sources and types into a single integrated display: real-time camera images from the implement's perspective, calculated future position data, and machine movement parameters. This combination provides comprehensive information about current and future implement positions, enabling informed decision-making while consolidating multiple data streams into one cohesive interface.
Solution Approach 2:
The system performs preliminary calculation of the implement's future position based on current parameters and displays this predicted information in advance. This allows the user to see not only where the implement is now but also where it will be with current control inputs, enabling proactive decision-making about positioning adjustments before they become necessary.
