Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If computer vision and image matching techniques are used for camera synchronization, then synchronization accuracy can be improved, but processing time and system complexity increase significantly

Engineering Contradiction:

Improvesynchronization accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces computer vision and image matching techniques with wireless communication transceiver signals for camera synchronization. Instead of using visual data processing, the system uses electromagnetic signals (WiFi, LiFi, Bluetooth Low Energy) to transmit timing information between cameras, achieving fast and accurate synchronization without the computational burden of image analysis.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless communication transceivers as intermediary devices that facilitate synchronization between cameras. These transceivers act as mediators by transmitting precise timing signals and localization data, enabling cameras to synchronize their operation without direct image-based communication or complex vision processing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If computer vision based localization is used to determine camera position and orientation, then localization accuracy can be improved, but the process becomes cumbersome and inefficient

Engineering Contradiction:

Improvelocalization accuracyVSAvoidoperational efficiency

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces computer vision based localization with wireless communication signal-based localization. By using the properties of electromagnetic signals (time of flight, angle of arrival, signal strength), the system determines camera positions and orientations without requiring image capture, feature extraction, or 3D model creation, thereby simplifying the operational process while maintaining accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent enables cameras to self-determine their position and orientation using their built-in wireless transceivers and sensors. Each camera independently processes signal data from wireless communications to calculate its own localization parameters, eliminating the need for external vision systems or centralized processing of image data from multiple cameras.

Inventive Principle:

Principle #25Self-service

Solution Approach 1:

The patent extracts the essential function of camera localization and synchronization from the complex 3D model creation and visualization pipeline. By using wireless communication signals to directly determine camera positions and orientations, the system eliminates the need for creating and processing 3D models, thereby reducing system complexity while still enabling multiview image and video generation.
