Detachable Dashcam Recording for Post-Event Scene Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dashboard cameras struggle to appropriately store the behavior of other vehicles and passengers after an event, such as an accident, due to limited capturing area and potential interference from vehicle vibrations.
Innovation Solution
A dashboard camera system that allows detachment from the vehicle post-event, enabling extended recording of the event aftermath in desired directions and positions, with event detection invalidated upon detachment, and storing this data as second event recording data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the dashboard camera remains attached to the vehicle after event detection, then the device structure is simple and stable, but the capturing area is limited and vehicle vibrations cause false detections
Solution Approach 1:
The dashboard camera is designed with a detachable structure that transitions from a fixed mounted state to a movable handheld state. The detection unit detects event occurrences, and upon detection, the camera can be detached from the vehicle by the user to continue recording in different locations and orientations, thus expanding the capturing area while managing device complexity through automated detection-triggered detachment.
2Reliability
If the dashboard camera remains attached to the vehicle, then the mounting structure is simple, but false event detections occur due to vehicle vibrations
Solution Approach 1:
The camera system transitions from a static mounted state to a dynamic handheld state upon event detection. The detection unit identifies genuine events, and the detachable mounting structure allows the user to remove the camera, preventing false detections from vehicle vibrations while maintaining a simple mounting structure that is only temporarily in place.
Solution Approach 2:
The camera is extracted from the vehicle mounting structure after event detection. The detachable design allows the camera to be removed from the potentially vibration-prone mounting location, eliminating the source of false detections while keeping the mounting structure itself simple and uncomplex.
3Reliability
If the dashboard camera is detached from the vehicle, then the capturing area expands and vibration interference is reduced, but the device requires more complex detachment mechanisms
Solution Approach 1:
The system employs a dynamic state transition where the camera moves from mounted to handheld mode based on detection events. The detachment mechanism is simplified by being event-triggered - the detection unit automatically initiates the detachment process when an event is detected, reducing the need for complex user-interface mechanisms while improving detection accuracy.
4Adaptability or versatility
If the dashboard camera is used in handheld mode after detachment, then the capturing area is expanded and positioning flexibility is improved, but the device becomes more difficult to operate
Solution Approach 1:
The detection unit performs preliminary detection of events while the camera is mounted. When an event is detected, the system automatically prepares for detachment, reducing the operational burden on the user. The camera is then detached and positioned handheld, providing adaptability and versatility for capturing post-event scenarios from multiple angles and locations.

AI summary
A recording apparatus (10) according to the present disclosure includes: a captured data acquisition unit (120) configured to acquire captured data captured by a camera that captures an image of an outside of a vehicle; an event detection unit (127) configured to detect an event with respect to the vehicle; an attachment/detachment detection unit (129) configured to detect an attachment/detachment state of the recording apparatus (10) with respect to the vehicle; and a recording controller (123) configured to store, when the event detection unit (127) has detected the event, captured data for a predetermined period of time due to the detected event as first event recording data, invalidate, when it is detected by the attachment/detachment detection unit (129) that the recording apparatus (10) has been detached from the vehicle, the detection of the event by the event detection unit (127) after the detection of the detachment, and store captured data after the detection of the detachment as second event recording data.
