Movable Knob Display Control for Adaptive In-Vehicle View Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle control knobs lack spatial compatibility and usability, limiting user benefits by not allowing for seamless interaction between the screen and controller, especially when switching between landscape and portrait view modes.
Innovation Solution
A display control system that includes an input unit to receive knob position information, a memory to store display control programs, and a processor to adjust the display content based on knob movement, allowing for adaptive UI control and position changes according to the view mode, enabling intuitive function selection and control through sliding and rotating motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional knob is fixed in its mounted area, then the device structure is simple, but the spatial compatibility and usability between screen and controller deteriorate
Solution Approach 1:
The knob is transformed from a fixed component to a movable one that can slide along the display surface. The processing unit detects the knob's position and controls display content accordingly, enabling dynamic adaptation to different spatial configurations and view modes while maintaining a relatively simple overall device structure
Solution Approach 2:
The movable knob serves multiple functions: it acts as both a physical controller and a positional indicator for display content. By moving the knob to different locations, users can access different functions and control modes, making a single component perform multiple roles that would otherwise require separate controls
2Adaptability or versatility
If the knob position is fixed, then the device structure is simple, but the adaptability to different view modes deteriorates
Solution Approach 1:
The system dynamically adjusts display content based on the knob's real-time position. When view mode changes between landscape and portrait, the processing unit recalculates which display area corresponds to the knob's current position, enabling automatic adaptation without additional hardware or complex manual reconfiguration
Solution Approach 2:
The processing unit continuously monitors the knob's position and uses this feedback to control the display output. This closed-loop system automatically adapts to different view modes by detecting knob position and adjusting the corresponding display content, eliminating the need for separate control systems for different orientations
3Adaptability or versatility
If multiple knobs and buttons are used to maintain functionality across view modes, then the functionality is complete, but the device complexity increases
Solution Approach 1:
A single movable knob replaces multiple fixed knobs and buttons. The same physical component can control different functions depending on its position and the current view mode, eliminating the need for separate controls for landscape and portrait orientations while maintaining complete functionality across all modes
Solution Approach 2:
The patent merges the functions of multiple potential knobs and buttons into a single unified movable knob. By combining position detection with functional control, the system achieves view mode adaptability with fewer components, reducing device complexity while preserving all necessary controls

AI summary
A display control system includes an input unit to receive position information of a knob, a memory to store a display control program in relation to a position of the knob, and a processor to execute the display control program to change a display of content in a display in consideration of the position information of the knob in relation to movement of the knob.
