Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a graphical user interface with touch screen display is implemented on industrial vehicles, then operator interaction and data display capability are improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions by both processing gesture commands from the touch screen display and mapping them to hardware controls, while also monitoring vehicle operating states and automatically switching between motion and lift screens. This multi-functionality reduces the need for separate dedicated components, thereby improving ease of operation without proportionally increasing device complexity.
Solution Approach 2:
The patent combines the touch screen display interface with the vehicle's existing control system by integrating gesture command detection and hardware control mapping within the same controller. This merging allows seamless interaction between touch gestures and hardware controls, improving operator interaction while avoiding the complexity of completely separate systems.
2Loss of information
If automatic switching between motion and lift screens is implemented based on vehicle states, then information accessibility is improved, but device complexity increases
Solution Approach 1:
The system continuously monitors vehicle operating states (such as whether the vehicle is in motion or performing lift operations) and uses this feedback to automatically switch between motion-related and lift-related screen displays. This feedback mechanism ensures that the most relevant information is always accessible to the operator without manual intervention, improving information accessibility while keeping the switching logic integrated within the existing controller.
Solution Approach 2:
The graphical user interface is made dynamic by automatically adapting its content based on real-time vehicle operating states. The system transitions between different screen configurations (motion screen vs. lift screen) depending on whether the vehicle is moving or performing lifting operations, ensuring that operators always see context-relevant information without manual reconfiguration.
3Ease of operation
If gesture commands are mapped to hardware controls, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller acts as an intermediary between the touch screen display and the vehicle's hardware controls. It receives gesture commands from the operator via the touch screen, interprets them, and maps them to the corresponding hardware control actions. This intermediary role enables intuitive touch-based operation while leveraging the existing hardware control infrastructure, improving ease of operation without requiring complete hardware replacement.
Solution Approach 2:
The system creates a virtual copy of hardware controls in the form of gesture-based touch screen interfaces. Operators can interact with virtual representations of control functions through gestures, which are then translated into actual hardware control signals. This copying approach allows operators to use intuitive touch gestures while the underlying hardware control system remains unchanged, improving ease of operation without significant additional complexity.

AI summary
A processing device having a graphical user interface includes a touch screen display that receives touch gesture commands from a vehicle operator and a controller. In operation, computer code implements a set of widgets such that at least one widget is normally viewable on the touch screen display. The set of widgets are organized to include at least one home screen, such as a motion home screen that displays at least one travel related widget, a lift home screen that displays at least one lift related widget, etc. When a current operating state of a control module of the industrial vehicle indicates that a designated control is engaged, the controller causes the display to snap to the associated home screen position.
