Vibration Motor Rotation for Headset Jack Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals are prone to damage from falls, particularly affecting components like the headset jack when connected to a headset plug, as existing technologies do not effectively prevent these components from contacting the ground during a fall.
Innovation Solution
An electronic device equipped with a sensor, processor, and vibration motor that monitors falls and determines if the headset jack is connected, executing a vibration operation to rotate the device by a target angle, thereby preventing the headset jack from contacting the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device falls, then the device itself may be damaged, but the headset jack and plug are particularly vulnerable to damage from contacting the ground
Solution Approach 1:
The system performs preliminary detection of fall status through sensors before actual damage occurs. When a fall is detected, the vibration motor is activated in advance to rotate the device and prevent the headset jack from contacting the ground, thus protecting the components before damage can happen.
Solution Approach 2:
The vibration motor serves as an intermediary mechanism between the fall detection sensor and the headset jack protection. It mediates the protective action by generating rotational motion that repositions the device, preventing direct contact between the vulnerable headset jack and the ground.
2Reliability
If the device rotates to protect the headset jack during a fall, then component damage is prevented, but the control system becomes more complex
Solution Approach 1:
The vibration motor performs multiple functions: it serves as both a normal vibration alert mechanism and a protective rotation actuator during falls. This multi-functionality reduces the need for additional dedicated protection components, thereby limiting the increase in system complexity while maintaining high protection effectiveness.
Solution Approach 2:
The device uses its own existing components (sensors, vibration motor, processor) to protect itself during a fall. The system autonomously detects the fall condition and activates the vibration motor to rotate the device into a protective position, eliminating the need for external protection systems.
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
Effectively prevents damage to the headset jack and plug by rotating the device to ensure another region contacts the ground instead, thus safeguarding these components during a fall.
Implementation Method 1
a sensor configured to monitor whether the electronic device falls or not
Implementation Method 2
the vibration motor is configured to, in the case that the headset jack is connected with the headset plug, execute a vibration operation to rotate the electronic device by a target angle
