Solution Overview

Problem

Placing augmented reality (AR) models in 3D scenes is a tedious and inflexible process, often requiring manual trial and error, and is constrained by fixed targets or objects, limiting user interaction and flexibility.

Innovation Solution

An augmented reality system that includes a scanner to create a 3D model of a space, a model store to store AR models with placement constraints, a location identifier to suggest candidate locations, a ranker to prioritize these locations based on various criteria, and a selector to automatically choose the best placement, reducing the need for user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual placement of AR models is used, then user control over placement is maintained, but the process becomes tedious and time-consuming

Engineering Contradiction:

Improveease of AR model placementVSAvoidtime for placement trial and error

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs automatic placement of AR models by analyzing the 3D scene and autonomously selecting optimal locations based on placement constraints, eliminating the need for manual trial-and-error placement while still allowing user override when needed

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-calculates and identifies candidate placement locations before the user needs to place the AR model, using algorithms to analyze the 3D scene and determine suitable positions in advance, thus saving time during the actual placement operation

Inventive Principle:

Principle #10Preliminary action

2Reliability

If fixed targets or objects are used for placement, then placement stability is improved, but flexibility in using or interacting with the AR model is limited

Engineering Contradiction:

Improveplacement stabilityVSAvoidflexibility of AR model placement

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system transitions from static fixed-target placement to dynamic placement by continuously analyzing the 3D scene and allowing AR models to be placed on any suitable surface or location that meets placement constraints, enabling the placement to adapt to different user needs and environmental contexts

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system creates a universal placement mechanism that works across diverse scenarios by identifying candidate locations based on general placement constraints rather than requiring specific fixed targets, allowing the same AR model to be flexibly placed in multiple different locations depending on user requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)
