Solution Overview

Problem

Conventional architectural modeling software is limited to two-dimensional displays, making it difficult for designers to perceive and interact with three-dimensional structures intuitively, and existing VR/AR systems lack efficient user interaction for editing and sharing models.

Innovation Solution

A VR/AR modeling system, Arkio, allows users to interact with a three-dimensional simulated environment using a handheld controller, enabling intuitive modeling and editing of polyhedral volumetric objects, with features like single-gesture operations, collision detection, and real-time collaboration, and supports computational efficiency for high-framerate display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional 2D CAD drawings and 3D models are used for architecture visualization, then the modeling process can be completed, but the ability to accurately represent spatial relationships and provide immersive experience is insufficient

Engineering Contradiction:
Improvemodeling capabilityVSAvoidspatial representation accuracy
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent creates a virtual copy of the physical architectural space using laser scanning to capture precise geometric data. This virtual model replicates the spatial relationships, dimensions, and structural characteristics of the physical environment, enabling accurate representation without requiring physical measurements or blueprints.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces traditional mechanical measurement methods (tapes, theodolites, manual surveying) with an automated laser scanning system. The laser scanner electronically captures spatial data by measuring the reflection of laser beams, substituting manual mechanical processes with optical-electronic detection to achieve higher precision and efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If laser scanning is used to capture spatial data, then measurement precision is improved, but the complexity of data processing and model generation increases

Engineering Contradiction:
Improvespatial data accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the complex laser scanning process into distinct functional stages: data collection (laser scanning), data processing (point cloud generation), and model generation (3D reconstruction). This segmentation allows each stage to be optimized independently, with specialized algorithms handling specific tasks like noise filtering, registration, and surface reconstruction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing layer that transforms raw laser scan data into usable 3D models. This intermediate step involves generating point clouds and converting them into mesh surfaces, acting as a bridge between the complex raw data and the final simplified model representation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If detailed 3D models are created from laser scan data, then spatial representation accuracy is improved, but the time required for data collection and processing increases

Engineering Contradiction:
Improvespatial data accuracyVSAvoiddata collection and processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent employs dynamic scanning capabilities where the laser scanner can operate in different modes (full scanning vs. selective scanning) based on the required level of detail. The system can adaptively adjust scanning parameters, resolution, and coverage to balance between measurement precision and time efficiency for different architectural elements.

Inventive Principle:
Principle #15Dynamics

AI summary

According to one aspect, an architectural modeling system is provided. The system includes an input controller configured to generate one or more input signals, a display including a display screen, and a system controller configured to be coupled to the input controller and the display. The system controller is configured to generate a three-dimensional simulated environment, display a field of view of the simulated environment on the display screen, receive, from the input controller, the one or more input signals indicative of a three-dimensional movement of the input controller, generate, based on the one or more input signals, a virtual object represented as a polyhedral volumetric object, and display the virtual object in the field of view of the simulated environment on the display screen.
