Magnetic Knob Placement on Vehicle Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face inconvenience due to fixedly glued knobs, which limit user flexibility and convenience in controlling vehicle electrical appliances, as they cannot be easily removed or repositioned without affecting the display screen's functionality.
Innovation Solution
A display device with a knob featuring a first magnetic adhering piece and a second magnetic adhering structure on the display panel, allowing the knob to be magnetically adhered to multiple positions on the panel, providing flexibility in placement and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the knob is fixed on the vehicle display screen by gluing, then the knob is securely attached to the display screen, but the user cannot easily remove or reposition the knob
Solution Approach 1:
The patent replaces the mechanical gluing system with a magnetic field-based adhesion system. The magnetic adhering structure generates magnetic attraction force to hold the knob on the display screen, allowing easy removal and repositioning while maintaining secure attachment during use.
Solution Approach 2:
The patent transitions from a static fixed attachment (gluing) to a dynamic magnetic attachment that allows the knob to be freely positioned and removed. The magnetic adhering structure enables the knob to be attached at multiple positions on the display screen according to user needs.
2Adaptability or versatility
If the knob is fixed in one position by gluing, then the attachment is stable, but the user lacks flexibility in controlling different vehicle electrical appliances
Solution Approach 1:
The patent makes the display screen serve multiple functions: it acts as both the display surface and the mounting surface for the knob. The magnetic adhering structure is integrated into the display screen, enabling the knob to be positioned at multiple locations to control different vehicle electrical appliances such as air conditioners and sound boxes.
3Adaptability or versatility
If multiple magnetic adhering regions are provided on the display panel, then the knob can be freely positioned, but the magnetic adhering structure becomes more complex
Solution Approach 1:
The patent divides the magnetic adhering structure into multiple independent magnetic adhering regions distributed on the display screen. Each region can independently adhere to the magnetic adhering piece on the knob, providing multiple positioning options while keeping each individual magnetic region relatively simple in structure.
