Smartglasses-Guided Building Marking for Precise Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for carrying out tradesperson tasks on building sites rely on paper drawings and handheld devices, which are inefficient for ensuring dimensional accuracy and require manual marking and measuring, lacking integration with digital tools for real-time guidance and verification.
Innovation Solution
A mini personal computer is attached to a mark on the building, linked to smartglasses via a data network, providing real-time reference lines and projected images to guide tradespersons, with AI-assisted BIM integration for digital installation instructions and workflow optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If paper drawings and handheld devices are used for guiding tradesperson tasks, then device complexity is reduced, but manufacturing precision and measurement precision deteriorate due to manual marking and measuring errors
Solution Approach 1:
The patent replaces manual mechanical marking and measuring operations with an optical projection system. The mini PC projects reference lines and markings directly onto the building surface through a projector, eliminating the need for manual marking tools and reducing human error in measurement and positioning, thereby improving installation precision while maintaining manageable system complexity
Solution Approach 2:
The patent creates digital copies of architectural plans and generates projected reference lines that serve as precise guides for installation. The mini PC stores and processes digital building data, projecting accurate reference markings onto the actual building surface, replacing paper drawings with dynamic digital projections that improve precision without requiring complex manual measurement systems
2Productivity
If manual marking and measuring operations are performed, then device complexity is minimized, but productivity deteriorates due to time-consuming processes
Solution Approach 1:
The patent replaces time-consuming manual marking operations with automated optical projection. The mini PC with projector instantly projects reference lines and markings onto the building surface, eliminating the sequential process of manual measurement and marking, thereby significantly improving workflow efficiency while introducing a manageable level of technological complexity
Solution Approach 2:
The patent performs preliminary digital preparation of installation data before the actual installation process. The mini PC stores pre-processed building data and generates all necessary reference lines and markings in advance, projecting them directly onto the building surface before installation begins, eliminating time-consuming on-site calculations and measurements
3Loss of information
If paper drawings are used for information transfer, then device complexity is reduced, but loss of information increases due to lack of real-time guidance
Solution Approach 1:
The patent creates digital copies of architectural information and processes them through the mini PC to generate real-time visual guidance. The system projects reference lines, markings, and installation information directly onto the building surface, ensuring accurate information transfer from digital plans to physical installation without the information loss inherent in manual interpretation of paper drawings
Solution Approach 2:
The patent replaces manual interpretation and transfer of information from paper drawings with automated optical projection. The mini PC processes digital building data and projects accurate reference information directly onto the building surface, eliminating human error in information interpretation and ensuring complete, accurate information transfer without requiring complex manual documentation systems
