Removable Vehicle Camera Interface Lockout During Device Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording devices may execute unnecessary processing due to erroneous operations when taken out of a vehicle, often triggered by incorrect interactions with the touch panel or buttons.
Innovation Solution
The device includes a data acquisition unit to detect phenomena associated with the action of removal, a determination unit to assess these data against predetermined conditions, and a control unit to disable the interface operation if these conditions are met, using data from cameras, sensors, and machine learning to prevent erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the video recording device is made portable and removable from the vehicle, then it can record a wider range of situations, but it may execute unnecessary processing due to erroneous operations when taken out
Solution Approach 1:
The system performs preliminary detection of removal phenomena (camera coverage, illuminance changes, motion detection) before the actual removal action is completed. When these preliminary indicators are detected, the system proactively disables interface operations in advance, preventing erroneous operations from occurring during the removal process.
Solution Approach 2:
The system introduces intermediate detection mechanisms (cameras, illuminance sensors, motion detectors) that act as mediators between the user's removal action and the device's operational state. These intermediaries detect subtle changes in the environment and user behavior, providing early warning signals that trigger the disablement of operations before erroneous input can occur.
2Reliability
If the interface operations are disabled during removal, then erroneous operations are prevented, but normal operations may also be restricted
Solution Approach 1:
The interface operational state is made dynamic rather than static. The system continuously monitors for removal phenomena and dynamically adjusts the interface state between enabled and disabled based on real-time detection results. This allows the interface to be fully usable during normal operation while automatically becoming disabled only when removal is detected, optimizing both usability and reliability.
Solution Approach 2:
The system implements a feedback mechanism where detection results from cameras, illuminance sensors, and motion detectors continuously inform the operational state of the interface. When removal phenomena are detected, feedback triggers the disablement of operations, and when normal conditions resume, feedback restores interface functionality, creating a self-regulating system that adapts to user needs.

AI summary
A video recording device includes a data acquisition unit configured to acquire data indicating a result of detecting a phenomenon associated with an action of taking the video recording device out from a vehicle, a determination unit configured to determine whether the result indicated by the data meets a predetermined condition, and a control unit configured to control the video recording device such that an operation for an interface used to operate the video recording device is disabled when the result indicated by the data is determined to meet the predetermined condition.
