Bumper Deployment Mechanism for Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with larger display screens are prone to screen damage from accidental falls due to the fragility of the display, resulting in unnecessary user loss.
Innovation Solution
A bumper deployment mechanism incorporating a rotating mechanism, first and second elastic parts, and a gravity sensor, where the gravity sensor detects acceleration and triggers the rotating mechanism to drive the elastic parts through the display panel to protrude and protect the screen upon detecting free fall, using motors and integrated rotating shafts with connecting rods to change states from a sealed to a shock-absorbing configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a larger display screen is used, then the display area is increased, but the fragility of the display increases making it more prone to damage from falls
Solution Approach 1:
The patent deploys a bumper structure around the display panel before impact occurs. The bumper includes elastic components that are pre-positioned to provide cushioning protection, reducing the harmful impact forces on the fragile display screen during accidental drops.
Solution Approach 2:
The patent employs a deployable bumper mechanism that transitions from a retracted state during normal operation to an extended protective state when impact is detected. This dynamic deployment allows the system to provide protection only when needed, maintaining display accessibility while preventing damage during falls.
2Object-affected harmful factors
If a deployable bumper mechanism is added to protect the display, then protection capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the bumper mechanism with existing device structures, combining protection functionality with the device frame or border. The elastic components are incorporated into the existing mechanical architecture, reducing the need for separate complex subsystems and minimizing overall device complexity.
Solution Approach 2:
The bumper mechanism utilizes the device's own structural components and existing materials to provide protection. The elastic parts leverage the device's frame as mounting structures, and the mechanism uses the impact force itself to trigger deployment, reducing the need for additional sensors, power sources, or control systems.

AI summary
An electronic device which is protected against screen breakage when dropped includes a display panel defining a through hole, a gravity sensor, a processor, and a bumper deployment mechanism. The bumper deployment mechanism includes a first elastic part and a connected rotating mechanism. The rotating mechanism includes a motor. The processor can compare a detected acceleration value with a preset acceleration value. When the detected acceleration value represents free-fall motion, which is greater than the preset acceleration value, the processor controls the motor to drive the first elastic part to pass through the through hole of the display panel and protrude from the display panel as a shock absorber.
