Flexible Display Device Free Fall Impact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices, such as mobile terminals, are prone to damage during free falls due to their rigid structure, which does not deform to absorb impact effectively.
Innovation Solution
A flexible display device design that includes a first and second body with a flexible display, an actuator, and a sensor, where the second body can move relative to the first body to change the device's shape and center of gravity during a free fall, allowing for deformation and rotation to distribute the impact and reduce damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the device maintains a rigid structure, then structural stability is improved, but impact resistance deteriorates
Solution Approach 1:
The patent implements a movable second body that can change position relative to the first body during free fall. The actuator moves the second body to a first position before impact and to a second position after impact, dynamically adjusting the device structure to absorb impact energy and reduce damage to the flexible display.
Solution Approach 2:
The patent changes the physical state and position parameters of the second body during free fall. By moving the second body between different positions, the center of gravity and moment of inertia are adjusted, enabling the device to rotate and deform in a controlled manner to distribute impact forces.
2Area of stationary object
If the flexible display is completely covered on two bodies, then display area is improved, but device complexity increases
Solution Approach 1:
The patent divides the device into two separate bodies with the flexible display spanning between them. The second body can move independently relative to the first body, allowing the display to be covered across both bodies while maintaining manageable structural complexity through modular design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces impact damage by changing its shape and center of gravity during a free fall, allowing the non-deformed portion to contact the ground first and minimizing stress on the flexible display and its components.
Implementation Method 1
a flexible display, an actuator, and a first sensor. The second body may reciprocate relative to the first body along a first direction between a first position and a second position
Implementation Method 2
the device being deformable in shape so as to be capable of reducing an expected impact or damage to the device when the device is in free fall
Implementation Method 3
the device being capable of rotating by deformation thereof when the device is in free fall

AI summary
A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, an actuator, and a first sensor. The second body reciprocates relative to the first body along a first direction between a first position and a second position. The flexible display includes a first region and a second region. As the second body moves from the first position to the second position, the area of the second region, forming the same plane as the first region, increases. The actuator may be operated such that the second body is moved toward the second position in response to free fall being detected by the first sensor, and damage to the flexible display device due to impact with the ground may thereby be reduced.
