Solution Overview

Problem

Existing dashboard cameras struggle to capture views in directions other than the front/rear of a vehicle without increasing cost by adding additional cameras for left/right monitoring during parking, and semi-spherical cameras are inadequate for appropriate recording.

Innovation Solution

A vehicle video system with front, rear, left, and right cameras, supported by rotatable arms, switches between electronic mirror and dashboard camera modes to capture and record views in all directions using existing camera hardware.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a semi-spherical camera is used to monitor lateral directions during parking, then the monitoring coverage is improved, but the recording quality and reliability are insufficient

Engineering Contradiction:
Improvemonitoring coverageVSAvoidrecording quality
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The monitoring system is segmented into multiple specialized cameras: front camera, rear camera, left camera, and right camera. Each camera is responsible for a specific directional view, allowing high-quality recording in each sector while collectively achieving comprehensive 360-degree coverage during parking monitoring.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The existing dashboard cameras and electronic mirror cameras are made multi-functional by enabling them to operate in both driving modes (electronic mirror) and parking modes (dashboard camera). This allows the same hardware to serve dual purposes, providing reliable recording quality without requiring additional specialized equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional cameras are installed to monitor left/right directions, then the monitoring capability is improved, but the cost increases

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidhardware cost
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system reuses existing dashboard cameras and electronic mirror cameras for dual purposes. During driving, these cameras function as electronic mirrors; during parking, they function as dashboard cameras for monitoring. This eliminates the need for additional dedicated cameras, maintaining monitoring capability while avoiding increased hardware costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The camera functions dynamically switch between different modes based on vehicle state. The control unit determines whether the vehicle is in driving or parking mode and accordingly switches the camera operation between electronic mirror function and dashboard camera function, maximizing the utility of existing hardware.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the vehicle is equipped with both dashboard camera and electronic mirror functions, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
Improvefunction versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The same camera hardware serves multiple functions: during driving operations, the cameras provide electronic mirror functionality for side views; during parking operations, the same cameras provide dashboard camera functionality for comprehensive surrounding monitoring. This multi-functionality reduces system complexity by eliminating redundant hardware while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts camera functionality based on vehicle state. The control unit switches between electronic mirror mode and dashboard camera mode according to whether the vehicle is in use or parked, allowing a single hardware configuration to handle multiple operational requirements without increasing complexity.

Inventive Principle:
Principle #15Dynamics
