Flexible Display Vibratory Notification Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile devices shrink in size, traditional vibratory notification motors add weight and size, necessitating a more compact solution for generating tactile notifications.
Innovation Solution
Implementing a flexible display with actuators that alter its position to create vibratory notifications, eliminating the need for dedicated motors by using command signals from a processor to manipulate the display or housing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor is used to generate vibratory notifications, then the notification function is achieved, but the device weight and size increase
Solution Approach 1:
The patent extracts the vibratory notification function from the traditional motor component and transfers it to the flexible display assembly. The display itself becomes the actuator, eliminating the need for a separate motor and thereby reducing device weight while maintaining the notification function.
Solution Approach 2:
The flexible display serves multiple functions: it displays visual information and simultaneously acts as an actuator for generating vibratory notifications. This multi-functionality eliminates the need for dedicated motor components, reducing overall device weight and complexity.
2Reliability
If a motor is used to generate vibratory notifications, then the notification function is achieved, but the device internal space increases
Solution Approach 1:
The patent removes the separate motor component from the device architecture and integrates the actuation function directly into the flexible display assembly, thereby freeing up internal space while maintaining the vibratory notification capability.
Solution Approach 2:
The patent merges the display function and actuation function into a single integrated assembly. The flexible display and its supporting structure serve as both the visual output device and the mechanical actuator, eliminating the need for separate motor housing and mounting space.
3Weight of moving object
If the flexible display position is altered to generate vibratory notifications, then device weight and space are reduced, but the actuator control complexity increases
Solution Approach 1:
The existing actuator designed for flexible display manipulation is made multi-functional by programming it to generate vibratory patterns. The same control signals that manipulate display position can also induce vibrations, reducing the need for separate control systems while maintaining reduced device weight.
Solution Approach 2:
The patent utilizes changes in the actuator's operational parameters (frequency, amplitude, duration) to generate different vibratory notification patterns. By modifying these parameters within the existing actuator's capability range, the system achieves complex notification functions without adding hardware complexity.
