Rollable Display Housing with Dual Vibration Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with rollable displays experience poor vibration effects due to localized vibration concentration when the extendable portion is extended, leading to subpar transmission of vibrations.
Innovation Solution
The electronic device incorporates a first and second housing with respective vibration motors, a flexible display, and drive mechanisms to switch between rolled and unrolled states, with a flexible electrical connection wire and winding mechanism to ensure consistent vibration feedback regardless of the device's state.

Engineering Contradiction Analysis
1Area of moving object
If the extendable portion is extended to provide larger display, then the display area is improved, but the vibration transmission effect deteriorates due to localized vibration concentration
Solution Approach 1:
The device is divided into a first housing with a first vibration motor and a second housing with a second vibration motor. The flexible display is divided into a first segment connected to the first housing and a second segment connected to the second housing. This segmentation allows vibration motors to be distributed across different housing sections, preventing localized vibration concentration and improving overall vibration transmission effectiveness while maintaining extended display capability.
2Device complexity
If a single vibration motor is used in the first housing, then the device structure is simple, but the vibration effect is subpar when the extendable portion is extended
Solution Approach 1:
The vibration feedback system is segmented into two independent vibration motors: a first vibration motor in the first housing and a second vibration motor in the second housing. Each motor can operate independently to provide vibration feedback in its respective housing region, improving overall vibration effect without requiring a single complex motor system.
Solution Approach 2:
Different vibration motors are assigned to different housing regions based on local requirements. The first vibration motor serves the first housing and the second vibration motor serves the second housing, allowing localized vibration optimization in each region while maintaining overall system simplicity.
