Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling a motor vehicle, especially in combination with a trailer, require complex and interruptive operations to set direction, speed, and steering angle, lacking simplicity and reliability.
Innovation Solution
A method and device utilizing a touch-sensitive input device to generate control signals for steering and drive systems, allowing continuous adjustment of direction, speed, and steering angle through positional input on the device, eliminating the need for separate actuations and providing intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate operating processes are used to set direction of travel and speed on touchscreen, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines multiple control functions (direction of travel and speed setting) into a single continuous gesture operation on the touchscreen. By merging these functions into one unified input mechanism, the system maintains control precision while significantly improving ease of operation, eliminating the need for separate pressing actions for each parameter.
Solution Approach 2:
The control system transitions from static discrete button presses to dynamic continuous gesture input. The touchscreen interprets the continuous movement and position of the input object, allowing both direction and speed to be controlled through a single dynamic gesture, thereby improving operational simplicity without sacrificing control accuracy.
2Reliability
If multiple separate controls are used for direction and speed, then reliability is improved, but device complexity increases
Solution Approach 1:
The touchscreen control system is designed to perform multiple functions (direction control and speed regulation) through a single universal interface. This multi-functional design reduces the number of separate control elements needed, simplifying the overall device complexity while maintaining operational reliability through integrated control logic.
3Ease of operation
If continuous gesture control is implemented, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms that continuously monitor the gesture input and provide real-time control adjustments. This feedback loop ensures that the continuous gesture input is accurately translated into precise control commands, maintaining measurement precision while benefiting from the ease of continuous gesture operation.
