An installation position information providing apparatus and method that uses an imaging device to capture video, recognize specific vehicle parts and the floor surface, calculate the installation position of adjustment facilities, and display this information in a superimposed manner on a display device, utilizing augmented reality to guide workers to the correct installation positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If labor-intensive surveys and multiple worker involvement are used to achieve accurate positioning of adjustment facilities, then positioning accuracy is improved, but installation time and man-hours increase significantly

Engineering Contradiction:

Improvepositioning accuracyVSAvoidinstallation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual surveying and mechanical positioning methods with an automated imaging system. The imaging device captures images of the vehicle, and image processing automatically identifies vehicle features and calculates adjustment facility installation positions, substituting labor-intensive mechanical surveying with automated optical-mechanical systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service positioning by automatically processing images to identify vehicle parts and calculate installation positions without requiring multiple workers to perform manual surveys. The image processing unit autonomously determines coordinates and generates guidance information, allowing single-operator or automated installation.

Inventive Principle:

Principle #25Self-service

2Device complexity

If manual surveying methods are used for installation positioning, then equipment complexity is reduced, but installation precision deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidinstallation precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

Manual surveying is replaced with an automated imaging and image processing system. The imaging device captures vehicle images, and the image processing unit automatically identifies vehicle features and calculates precise installation positions, achieving high precision without complex manual measurement equipment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a digital representation (image) of the vehicle and processes this copy to determine installation positions. By working with image data rather than physical measurements, the system achieves precise positioning while maintaining relative simplicity in the physical installation process.

Inventive Principle:

Principle #26Copying

3Measurement precision

If multiple workers are involved in the installation process, then positioning accuracy is maintained, but productivity decreases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidinstallation efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system performs self-service by automatically capturing images, processing them to identify vehicle features, and calculating installation positions without requiring multiple workers. The automated guidance information enables single operators to achieve the same positioning accuracy that previously required multiple workers.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The collaborative human effort of multiple workers is replaced with an automated system comprising imaging devices and image processing units. This mechanical-automated system maintains positioning accuracy while dramatically improving installation efficiency by eliminating the need for multiple workers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In an installation position information providing apparatus, specific two parts in a vehicle or in a vicinity of the vehicle and a floor surface on which the vehicle is mounted are recognized from a video that is captured, an installation position of an adjustment facility in the video is calculated based on the two parts and the floor surface that are recognized, and an installation position object indicative of the installation position is displayed at the installation position that is calculated in a superimposed manner, in the video that is displayed.
