Wearable Video Recorder With Ear Connector And Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video cameras require manual operation and support, making it difficult to capture unexpected events as they often need to be turned on and positioned correctly before recording, and there is no continuous recording capability.
Innovation Solution
A wearable video recording device with a camera, control unit, and ear connector that continuously records video and allows users to activate a real-time mode for predetermined duration recording, automatically saving footage and deleting excess, with a vibration sensor to detect crashes or falls and save relevant footage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a video camera requires manual operation and support (tripod or handheld), then the device structure is simple, but it is difficult to capture unexpected events and requires manual intervention
Solution Approach 1:
The device performs preliminary actions by continuously recording video footage before an event occurs and storing it in a buffer. This allows the system to capture unexpected events without requiring manual intervention, as the recording is already in progress and ready to be saved when needed.
Solution Approach 2:
The patent introduces an intermediary buffer memory that stores video footage between recording and final saving. This buffer acts as a mediator that holds the recorded data temporarily, allowing the system to manage footage automatically without complex real-time processing or manual control mechanisms.
2Reliability
If the device continuously records video footage, then unexpected events can be captured, but storage space is consumed and management becomes complex
Solution Approach 1:
The system performs preliminary recording and buffers the footage in memory before an event is detected. This preliminary action allows the device to have footage ready immediately when an event occurs, ensuring reliable capture without needing to continuously save all footage to permanent storage.
Solution Approach 2:
The patent implements a buffer management system that automatically discards old footage when the buffer is full and recovers storage space by deleting unsaved footage. This allows continuous recording capability while managing limited storage resources efficiently, as only relevant footage is retained.
3Loss of information
If the device saves all recorded footage, then no important moments are missed, but the user cannot distinguish important events from ordinary footage
Solution Approach 1:
The system uses feedback from sensors (accelerometer, gyroscope, microphone) to detect events and provide information about what is happening during recording. This feedback mechanism allows the device to automatically identify and save important footage based on detected events rather than saving everything, simplifying footage management while preserving important moments.
Solution Approach 2:
The device performs self-service by automatically detecting events through sensors and saving relevant footage without user intervention. The system monitors its own recording state and environmental conditions, making autonomous decisions about what footage to preserve, thereby reducing the complexity of manual footage management.
4Loss of time
If the device requires manual button pressing to start recording, then the operation is simple, but the user cannot capture events that occur before manual activation
Solution Approach 1:
The device maintains continuous recording action by constantly capturing video footage and buffering it in memory. This continuous operation eliminates the need to manually start recording before an event, as the useful action of recording is already ongoing and ready to capture any unexpected event immediately.
Solution Approach 2:
The system performs preliminary recording by continuously capturing and buffering video footage before an event occurs. This preliminary action ensures that when an event happens, the recording is already in progress and the footage is immediately available for saving, eliminating any response time delay.
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
Enables continuous, hands-free video recording of unexpected events, allowing users to capture important moments without manual intervention and saving desired footage while automatically managing recording duration and detecting critical events.
Implementation Method 1
The control unit may include a vibration sensor configured to detect movement corresponding to at least one of a crash and a fall by the user and automatically save the at least one video on the control unit.
