Detachable Knob Display Control System for Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems using knobs in vehicles face usability issues due to spatial incompatibility between the manipulation target screen and controller, limiting user convenience and functionality.
Innovation Solution
A display control system that includes an input part for receiving position information of a knob, a memory for storing a display control program, and a processor that executes the program to control vehicle functions based on knob movement and operation, allowing for seamless integration of function control, pop-up screens, volume management, and window switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional knob is fixed to the console, then the device structure is simple, but spatial compatibility between manipulation target screen and controller is poor
Solution Approach 1:
The knob is designed to be movable between two positions: under the display (for spatial compatibility with manipulation targets) and in the console (for simple structure). This dynamic repositioning allows the system to switch between optimizing for ease of operation and device simplicity based on usage context.
Solution Approach 2:
The single knob serves multiple functions: it acts as both a physical controller and a touch input device depending on its position. When under the display, it provides touch input for spatially compatible control; when in the console, it serves as a traditional rotary controller, thus one component fulfills multiple operational roles.
2Adaptability or versatility
If multiple buttons are provided for different functions, then function versatility is improved, but device complexity increases
Solution Approach 1:
The single knob is designed to perform multiple functions including rotation for scrolling, pressing for selection, and touching the display for direct input. This multi-functional design replaces what would traditionally require multiple separate buttons, achieving function versatility while maintaining simple device structure.
Solution Approach 2:
The knob acts as an intermediary between the user and the display system. By positioning the knob under the display, it serves as a mediator that provides both physical tactile feedback and direct touch input capability, bridging the gap between traditional physical controls and modern touch interfaces.

AI summary
A display control system using a knob includes an input part which receives at least one piece of position information of a knob within a movement range in an area under a display and position information of the knob within a preset plane area, a memory in which a display control program using the position information of the knob is stored, and a processor which executes the program, and the processor controls a function in a vehicle in consideration of the position information according to movement of the knob and operation information of the knob.
