Adaptive Visual-Haptic Variable Button for Dynamic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buttons for electronic devices struggle to adaptively provide various types of visual-haptic information, as the sense of button manipulation and touch are fixed during manufacturing, making it difficult to change purposes or provide accurate haptic feedback without replacing the buttons.
Innovation Solution
A visual-haptic variable button that includes a visual information output part and a haptic information output part, allowing adaptive changes in button icons, sense of button manipulation, and sense of button touch through a setting and control system, enabling dynamic output of visual and haptic information based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If buttons are manufactured with fixed haptic mechanisms (springs, oil pressure) and visual icons during the initial manufacturing stage, then the button structure is simple and manufacturing is easy, but the sense of button manipulation and button icons cannot be changed afterward
Solution Approach 1:
The button icon is changed from a static printed/engraved pattern to a dynamic display element (such as an LED or other visual output device) that can be controlled to show different patterns, colors, or text based on the button's current function, allowing the visual information to adapt without changing the physical button structure
Solution Approach 2:
A single button structure with a display element is designed to serve multiple functions by dynamically changing its visual output and haptic feedback characteristics, replacing the need for multiple specialized buttons for different purposes
2Adaptability or versatility
If separate buttons are added to provide different haptic information for different purposes, then various haptic information can be provided, but the device complexity and number of buttons increase
Solution Approach 1:
The haptic mechanism is designed with adjustable parameters (such as spring stiffness, pre-load force, or damping characteristics) that can be dynamically modified through actuators or variable mechanical elements, allowing a single button to provide multiple distinct haptic feedback types based on the desired function
Solution Approach 2:
The physical parameters of the haptic mechanism (force, stiffness, damping, travel distance) are made variable through control systems that can adjust these parameters in real-time, enabling one button to simulate multiple different haptic sensations without requiring multiple physical buttons
3Adaptability or versatility
If button icons are printed, engraved or embossed during manufacturing, then the visual information is stable and clear, but the button purpose cannot be changed afterward
Solution Approach 1:
The button icon is replaced with a display element (such as an LED, OLED, or other visual output device) that can dynamically change its output based on the button's current function, maintaining visual clarity while enabling purpose changes without manufacturing new buttons
Solution Approach 2:
Instead of physically engraving or embossing the button icon during manufacturing, a digital representation is stored and reproduced on demand through the display element, allowing instant changes to the visual information without any physical manufacturing changes

AI summary
A button for providing visual-haptic information includes a visual-haptic variable button that adaptively provides various types of visual-haptic information according to input of information to an electronic apparatus. The visual-haptic variable button includes a visual information output part that adaptively changes various types of button icons according to manipulation and touch of the visual-haptic variable button for the input of information, thereby outputting visual information, and a haptic information output part that adaptively changes various types of sense of button manipulation and sense of button touch according to the manipulation and touch of the visual-haptic variable button, thereby outputting haptic information. At least one visual-haptic variable button is provided in the electronic apparatus for the input of information.
