Vehicle Black Box Dynamic Video Recording Control

Solution Overview

Problem

Conventional vehicle black boxes cannot effectively record and store video data with high quality and resolution during potential car accidents, limiting their ability to provide objective data for accident analysis.

Innovation Solution

A system that adjusts the video recording quality, resolution, and frame per second (FPS) based on the likelihood of an accident, using a controller to enhance storage capacity and monitoring performance by increasing these parameters when an accident is possible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If video recording quality and resolution are increased continuously, then clearer video data is obtained, but storage capacity is exhausted quickly

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies dynamics by making the video recording parameters (quality, resolution, FPS) variable rather than fixed. The controller dynamically adjusts these parameters based on real-time accident possibility assessments, transitioning between different recording modes (normal, warning, accident) to optimize both video quality and storage utilization

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying video recording characteristics (quality, resolution, frame rate) based on detected accident possibilities. When accident possibility is high, the system increases these parameters to capture detailed evidence; when low, it reduces them to conserve storage space

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If video recording quality and resolution are increased continuously, then clearer video data is obtained, but energy consumption increases

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts video recording parameters based on real-time accident risk assessment. During normal operation with low accident probability, the system uses lower quality settings to minimize energy consumption. When warning or accident states are detected, it transitions to high-quality recording mode to ensure adequate evidence capture

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes video recording parameters (quality, resolution, FPS) according to detected accident possibilities. This conditional parameter adjustment ensures high energy consumption only occurs when necessary for evidence collection, rather than continuous high-quality recording

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If simple and superficial information is recorded, then storage capacity is preserved, but effective meeting of user demands is limited

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The black box system dynamically adapts its recording behavior based on detected accident possibilities. It transitions between normal recording mode (preserving storage) and enhanced recording mode (satisfying user demand for detailed evidence) based on real-time conditions, making the system versatile in meeting different user needs

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes video recording parameters based on accident detection results. When accidents are detected, it automatically increases quality and resolution to provide comprehensive evidence for users. This conditional parameter adjustment allows the system to balance storage preservation with user demand satisfaction

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided are an apparatus and a method for controlling a video recording in a black box for vehicle. The method for controlling the video recording in the black box for a vehicle according to the present invention, for example, comprises the steps of: storing a video including images of a driving vehicle; obtaining the possibility of an accident with the vehicle; and variably adjusting one or more image quality, resolution, and a frame accident possibility. The limited capacity of storage can be used by adopting the configuration. In addition, the monitoring and storage performance of the black box for a vehicle can be improved by correctly determining causes of a vehicle accident.
