Vibration Mode Switching for Panel Operational Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input systems for panels fail to provide a sufficient operational feeling to users, as they typically rely on a single vibration frequency, which does not effectively convey different types of user interactions.
Innovation Solution
A control device with an operation detecting unit and a drive unit that switches between first and second vibration modes of different frequencies, providing distinct vibrations to the panel based on user operations, such as slide or pressing actions, to enhance the operational feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single vibration frequency is used to simplify the system, then the device complexity is reduced, but the operational feeling given to the user is insufficient
Solution Approach 1:
The patent applies dynamics by switching between different vibration modes (first and second modes with different frequencies) based on the detected operation type. The system transitions from a static single-frequency vibration to a dynamic multi-frequency vibration system that adapts to different user interactions, thereby improving operational feeling without requiring a permanently complex multi-frequency system.
Solution Approach 2:
The patent changes the vibration frequency parameter based on the detected operation type. When a slide operation is detected, the system uses a first vibration frequency, and when a pressing operation is detected, it switches to a second vibration frequency. This parameter change allows the system to provide differentiated operational feedback for different interaction types while maintaining system simplicity.
2Ease of operation
If multiple vibration frequencies are used to improve operational feeling, then the operational feeling is enhanced, but the device complexity increases
Solution Approach 1:
The system dynamically switches between vibration modes based on operation detection rather than maintaining multiple simultaneous vibration systems. This dynamic approach allows the system to provide complex multi-frequency feedback when needed while maintaining a simpler architecture when operating in single-frequency mode, thus improving operational feeling without proportionally increasing device complexity.
Solution Approach 2:
The vibrating element serves multiple functions by operating in different vibration modes for different operation types. A single vibrating element structure is designed to support both first and second vibration modes, making it multi-functional. This universality allows the system to provide differentiated operational feedback without requiring separate vibrating elements for each frequency, thereby reducing overall device complexity.

AI summary
There is provided a control device. An operation detecting unit configured to detect an operation of a user on an operation surface of a panel. A drive unit configured to drive a vibrating element attached to the panel, thereby vibrating the panel. If the operation detecting unit detects the operation, the drive unit drives the vibrating element while switching between a first vibration mode and a second mode different in at least some vibration frequencies, thereby sequentially giving different types of vibration different in at least some frequencies to the panel.
