Solution Overview

Problem

Existing 2D computer screen-based CAD model visualization struggles with information clutter and occlusion, making it difficult to interact with and explore complex 3D models, especially when displaying metadata without obscuring the model or requiring significant reorientation.

Innovation Solution

A virtual reality system with a multi-space environment separates the 3D CAD model from its metadata, using a semi-transparent floor to connect two spaces, allowing users to view the model in one space and metadata in another without occlusion, enabling immersive exploration and intuitive interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If metadata is displayed on panels that overlap the 3D model or require the model to be smaller, then information about the model is provided, but the model becomes occluded or harder to interact with

Engineering Contradiction:
Improvemetadata visibilityVSAvoidmodel interaction
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent transitions from 2D screen display to 3D virtual reality environment, utilizing the third dimension to separate the model and metadata in space. The model remains in the central viewing area while metadata is displayed on virtual panels positioned around the periphery or at different depths, eliminating occlusion by distributing information across multiple spatial dimensions rather than overlapping on a flat surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The virtual reality environment segments the display space into distinct regions: the central space for the 3D model and peripheral or layered spaces for metadata panels. This spatial segmentation allows users to focus on the model while metadata is available in separate visual zones, reducing cognitive overload and visual clutter.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the 3D model is displayed at full scale to maintain detail, then model accuracy is preserved, but metadata cannot be displayed without requiring the model to be smaller

Engineering Contradiction:
Improvemodel detailVSAvoidmetadata display
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

By moving to 3D virtual reality, the system gains additional display real estate around and around the central model. Metadata panels can be positioned at various distances and angles, allowing full-scale model display while providing accessible metadata through spatial distribution rather than compression.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of information

If multiple tools and metadata are displayed on a 2D screen, then information density is high, but the interface becomes overwhelming and hard to navigate

Engineering Contradiction:
Improveinformation densityVSAvoidinterface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The virtual reality interface segments information into spatially separated modules: the 3D model in the center, metadata panels positioned around the periphery, and tool controls accessible through gestures or menus. This spatial segmentation reduces interface complexity by distributing elements across three-dimensional space rather than crowding them on a 2D plane.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transition to 3D virtual reality provides additional spatial dimensions for organizing interface elements. Tools and metadata can be arranged in radial or layered configurations around the model, creating an intuitive spatial hierarchy that reduces cognitive load compared to flat 2D layouts.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

For display of a 3D model (20) in virtual reality (VR), merely converting the CAD display from the 2D screen to a 3D image may not sufficiently reduce the information clutter. To provide metadata for the 3D CAD model (20) with less occlusion or clutter, a separate space (32) is generated in the virtual reality environment. Metadata and information about the 3D CAD model (20) and/or selected part (36) of the 3D CAD model (20) is displayed (58) in the separate space (32). The user may view the 3D CAD model (20) in one space (30), the metadata with or without a representation of a part in another space (32), or combinations thereof.
