Steering Wheel Rotation Display for Multi-Turn State Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not effectively convey the rotated state of a steering wheel to users, making it difficult to understand the number of rotations, direction, and operational status of the steering wheel.
Innovation Solution
An information processing method that obtains the rotated amount of a steering wheel and controls a display device to display a steering wheel image in a mode corresponding to the number of rotations, direction, and operational status, using a display device to visualize this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional display shows only basic steering wheel operation information, then the display device is simple, but the user cannot readily understand the rotated state of the steering wheel
Solution Approach 1:
The patent creates a visual copy of the steering wheel on the display that replicates the actual steering wheel's rotated state. This graphical representation mirrors the physical steering wheel's position and rotation, allowing users to understand the rotated state without complex additional information. The copy principle resolves the contradiction by providing intuitive visual feedback that matches the physical state.
Solution Approach 2:
The patent employs color changes in the displayed steering wheel image to indicate different operational states and rotation directions. By changing colors based on rotation direction (left/right) and state (operational/non-operational), the system conveys multiple pieces of information through a simple visual parameter change, avoiding the need for complex display mechanisms.
2Loss of information
If the display shows detailed rotation information, then user understanding improves, but the information processing complexity increases
Solution Approach 1:
The patent segments the steering wheel display into distinct visual components: the steering wheel image itself, rotation direction indicators, and operational state markers. By dividing the information presentation into separate visual elements, the system processes and displays rotation information efficiently without requiring complex integrated processing. Each segment handles specific information independently.
Solution Approach 2:
The patent implements dynamic updating of the steering wheel display based on real-time rotation input. The display automatically adjusts to reflect current rotation state, direction, and operational status without requiring manual intervention or complex processing. The dynamic nature of the display allows it to adapt to changing states while maintaining simple processing logic through event-driven updates.
