Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used for vehicle video shooting, then the device complexity is reduced, but the video content richness and coverage of multiple directions are insufficient
Solution Approach 1:
The patent implements multi-functionality by enabling a single camera to perform multiple shooting directions through rotational movement. The camera can switch between front, rear, left, and right shooting directions, making one camera replace multiple fixed cameras while maintaining comprehensive coverage capability.
Solution Approach 2:
The patent applies dynamics by making the camera rotatable rather than fixed. The camera can dynamically adjust its shooting direction based on vehicle driving status (forward, reverse, left turn, right turn) and user interest directions, transforming a static single-direction camera into a dynamic multi-directional camera system.
2Adaptability or versatility
If multiple cameras are activated simultaneously to capture all directions, then the video content richness is improved, but the energy consumption and device complexity increase
Solution Approach 1:
The patent implements partial action by activating only the necessary camera based on current driving conditions rather than all cameras simultaneously. The system determines the required shooting direction from driving status and user interest, then activates only that specific camera, reducing energy consumption while maintaining adequate coverage.
Solution Approach 2:
The system dynamically selects which camera to activate based on real-time driving status and user interest. Instead of static full-coverage activation, the camera activation is dynamic and conditional, optimizing energy usage based on actual shooting requirements.
3Device complexity
If the camera shooting direction is fixed, then the device complexity is reduced, but the ability to capture user interest directions is insufficient
Solution Approach 1:
The patent makes the camera shooting direction dynamic rather than fixed. The camera can rotate to align with user interest directions detected through facial recognition, while the control logic remains relatively simple by following predefined rules based on driving status and user direction.
Solution Approach 2:
The system uses feedback from facial recognition to detect user interest direction, then adjusts the camera shooting direction accordingly. This closed-loop feedback mechanism enables the camera to capture user interest without requiring complex manual control.
4Device complexity
If the shooting mode is fixed, then the device complexity is reduced, but the adaptability to different driving speeds and conditions is insufficient
Solution Approach 1:
The patent implements dynamic shooting mode selection based on driving speed and conditions. The system automatically adjusts between normal speed mode, high speed mode, and time-lapse mode according to real-time driving status, making the shooting parameters adaptive rather than fixed.
Solution Approach 2:
The system changes shooting parameters (frame rate, exposure time, etc.) based on driving conditions. By adjusting these parameters dynamically according to speed and driving status, the system achieves adaptability without requiring complex hardware changes.

AI summary
Provided are a method, apparatus, and system for controlling vehicle cameras to generate videos, the method comprising: acquiring driving information of the vehicle and preset matching information, wherein the driving information comprises at least driving direction information and braking status information of the vehicle, and the preset matching information comprises first matching information which defines a matching relationship between the driving direction information and/or braking status information of the vehicle and activation of a corresponding vehicle camera; and according to the first matching information, selecting and activating the corresponding vehicle camera among a plurality of vehicle cameras on the basis of the driving direction information and/or braking status information of the vehicle to shoot an exterior or interior of the vehicle to generate the video. Thus, the shooting camera can be automatically adjusted according to the driving direction and/or braking status, thereby increasing driving video shooting modes, meeting users' needs for shooting in diversified directions, and providing users with driving videos featuring richer content.
