Operator Display for Machine and Implement Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work machines lack an effective display system for operators to determine the proper alignment and orientation of digging implements relative to the machine and work surface, leading to inefficiencies and inaccuracies in excavation operations due to visual obstructions and the need for manual estimation.
Innovation Solution
A machine orientation display system that includes a horizontal reference and indicators for machine and implement orientations, sensed by orientation sensors and processed by an electronic control module to provide a graphical representation on an operator display, ensuring accurate positioning and orientation of the implement relative to the machine and work surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If numerical indicators are used to show implement orientation, then information can be displayed, but the operator finds it difficult to accurately determine implement position and orientation
Solution Approach 1:
The patent creates a visual copy or graphical representation of the implement's actual position and orientation on the display. Instead of showing raw numerical data, the system generates a simulated view that mirrors what the operator would see if they could physically observe the implement, making the information intuitive and easy to interpret without requiring specialized knowledge or constant reference to numerical values
Solution Approach 2:
The patent transforms one-dimensional numerical indicators into a two-dimensional visual display that represents the implement's position and orientation in space. By adding spatial dimensionality to the display, the system provides comprehensive orientation information (pitch, roll, and position) in a single visual field rather than requiring the operator to interpret multiple separate numerical values
2Measurement precision
If the operator stops the work machine to determine implement position, then accurate positioning can be achieved, but time is increased and efficiency is reduced
Solution Approach 1:
The patent implements a continuous feedback system that provides real-time visual information about implement position and orientation to the operator during operation. The display updates dynamically as the implement moves, allowing the operator to make continuous adjustments without stopping the machine, thereby maintaining both accuracy and productivity
Solution Approach 2:
The system provides advance visual information about implement position trends, allowing the operator to anticipate and prepare for positioning adjustments before they are needed. This preliminary visual feedback enables proactive control rather than reactive corrections that would require stopping the machine
3Productivity
If the implement goes below grade or is visually obstructed, then digging operations can be performed, but the operator loses sight of the implement making position determination harder
Solution Approach 1:
The patent introduces a display system as an intermediary between the implement and the operator. When the implement is below grade or obstructed from direct view, the display acts as a mediator that captures sensor data about the implement's position and orientation and presents it in a visually intuitive format, allowing the operator to 'see' the implement's position indirectly through the display representation

AI summary
A machine orientation display may be displayed by an operator display device in an operator station of a machine. The machine orientation display may include a field area, a horizontal reference displayed on the field area, a machine orientation indicator displayed on the field area and positioned and oriented relative to the horizontal reference to graphically indicate a machine orientation of the machine relative to a work surface on which the machine is disposed. The machine orientation display may further include an implement orientation indicator displayed on the field area and positioned and oriented relative to the horizontal reference and the machine orientation indicator to graphically indicate an implement orientation of an implement of the machine. The implement is movable relative to a machine body of the machine and to the work surface.
