Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional rearview mirrors are used to observe road environment, then the driver can see the rear view, but the reflected light from overtaking vehicles causes visual dizziness and reduces visual ability

Engineering Contradiction:

Improvelight sensitivityVSAvoidvisual ability

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent replaces the conventional optical reflection system with an electronic imaging system. Image capturing modules (cameras) are installed at the front, rear, and sides of the vehicle to capture road environment images, which are then displayed on screens within the vehicle. This substitution eliminates the problem of reflected light causing visual dizziness while providing comprehensive road information.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If conventional rearview mirrors are used, then the structure is simple, but blind vision areas exist that prevent complete observation of road information

Engineering Contradiction:

ImprovestructureVSAvoidblind vision area

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent divides the road monitoring function into multiple image capturing modules positioned at different locations (front, rear, left, right sides of the vehicle). Each module captures images of specific areas, and the images are displayed on corresponding screens. This segmentation eliminates blind spots by providing comprehensive coverage of all road directions without requiring a single complex mirror system.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the driver constantly changes line of sight to check all directions, then complete road information can be obtained, but reaction time increases and safety decreases

Engineering Contradiction:

Improvedriving safetyVSAvoidreaction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the road information from all directions (front, rear, left, right) into a single integrated display system within the vehicle. Multiple image capturing modules capture images simultaneously, and these images are displayed on screens that the driver can view without changing line of sight. This allows the driver to obtain complete road information from all directions at once, eliminating the need to constantly turn the head or shift attention between different mirrors.

Inventive Principle:

Principle #5Merging (Combining)

4Area of stationary object

If image capturing modules with wide viewing angle are used, then comprehensive road information can be captured, but imaging quality may be reduced

Engineering Contradiction:

Improveviewing angleVSAvoidimaging quality

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent uses multiple image capturing modules positioned at different spatial locations around the vehicle, each capturing images of specific directions. By distributing the imaging function across multiple modules in different dimensions (front, rear, left, right), the system achieves both wide overall coverage and high imaging quality in each specific direction, avoiding the trade-off that would exist with a single wide-angle lens.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A movable carrier auxiliary system includes an environment detecting device including an image capturing module, a storage module, and an operation module. The image capturing module is disposed on a movable carrier for capturing an environment image around the movable carrier. The storage module stores a plurality of image models. A control method thereof includes that the operation module is electrically connected to the image capturing module and the storage module to detect whether the environment image has an image that matches at least one of the image models or not, and to generate a corresponding detection signal.
