RFID Tagged Building Components for Precise Site Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction companies face challenges in accurately determining the location of building components on construction sites, leading to inefficiencies and potential safety hazards due to the lack of clear placement instructions for delivered equipment and tools.
Innovation Solution
The method involves attaching RFID tags to building components, which store their predetermined location on the site, and using optical or physical markings to identify these components, allowing for precise positioning through RFID technology and Building Information Modeling (BIM) databases, enabling accurate tracking and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual tracking methods are used for building components, then the system complexity is low, but the location accuracy and tracking efficiency are insufficient
Solution Approach 1:
The RFID tag serves multiple functions: it stores component identification data, location information, and installation status. This multi-functionality reduces the need for separate tracking systems while improving location accuracy, resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent creates a digital replica of the physical building site through BIM (Building Information Modeling) that mirrors the actual component locations. This virtual model allows precise tracking and visualization of component positions without requiring complex physical tracking infrastructure, thereby improving measurement precision while managing system complexity
2Productivity
If RFID tags with location data are attached to all building components, then location tracking accuracy improves, but the cost and time for tagging increase
Solution Approach 1:
RFID tags are attached to building components during the manufacturing process before delivery to the construction site. This preliminary action ensures that components are already tagged and ready for immediate tracking upon arrival, improving productivity while minimizing the time required for tagging at the construction site
Solution Approach 2:
The patent combines the RFID tagging process with the existing component manufacturing and delivery workflow. By integrating tag attachment into the standard production process, the system improves tracking efficiency without significantly increasing overall time investment, as tagging becomes a routine part of component preparation rather than a separate construction phase
3Manufacturing precision
If precise location data is stored in RFID tags, then component placement accuracy improves, but information management complexity increases
Solution Approach 1:
The BIM (Building Information Modeling) system serves as an intermediary between the RFID tags and the construction management team. The BIM model centralizes and visualizes location data from all RFID tags in an intuitive 3D representation, improving placement accuracy while simplifying information management by providing a unified interface rather than requiring direct management of individual tag databases
