Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SLAM techniques and 3D reconstruction are used to create augmented reality experiences, then the immersion and accuracy of the AR experience is improved, but the computational overhead and storage needs increase significantly

Engineering Contradiction:

ImproveAR experience accuracyVSAvoidcomputational overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex SLAM and 3D reconstruction components from the AR system, replacing them with a simplified approach that uses only 2D image processing and overlay techniques. This extraction eliminates the computational burden of building and maintaining 3D environmental models while preserving the core AR functionality of displaying augmented content over the real-world view.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of creating persistent 3D models of the environment that require significant storage and processing resources, the system uses lightweight 2D image frames that are processed and discarded after each frame. The augmented reality content is rendered as 2D overlays on top of current camera frames rather than being integrated into permanent 3D models, dramatically reducing computational overhead and storage requirements.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

If traditional sensor systems are used without AR integration, then the system complexity is kept low, but the user experience enhancement and application versatility are limited

Engineering Contradiction:

Improvesystem complexityVSAvoidapplication versatility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal AR platform that can support multiple applications (gaming, education, entertainment, navigation) using the same core technology stack. The system uses existing vehicle sensors and cameras to provide a unified AR interface that can be adapted to different use cases without requiring separate systems for each application, thereby increasing versatility while maintaining manageable complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an AR processing system as an intermediary layer between the vehicle's existing sensors and the user interface. This mediator takes standard sensor inputs (camera feeds, sensor data) and transforms them into augmented reality presentations, enabling enhanced user experiences without directly modifying the underlying sensor systems or requiring complex integration of multiple specialized subsystems.

Inventive Principle:

Principle #24Intermediary (Mediator)
