Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional construction technologies are used without XR application, then device complexity remains low, but construction precision deteriorates due to frequent errors
Solution Approach 1:
The patent introduces XR content as an intermediary between the construction worker and the construction site. The XR display unit overlays virtual construction information (design drawings, positioning data, instructions) onto the real-world view, serving as a mediator that delivers precise construction guidance without requiring complex traditional surveying equipment or manual interpretation of blueprints
Solution Approach 2:
The patent replaces traditional mechanical surveying and measurement systems with an optical-informatics system. Instead of using thesensory unit to recognize ID codes and automatically retrieve corresponding construction information from a database, eliminating the need for manual measurement and information lookup processes
2Manufacturing precision
If XR technology is applied to display construction information, then construction precision improves, but loss of time increases due to system setup and operation
Solution Approach 1:
The patent prepares construction information in advance by pre-processing design data, positioning information, and construction instructions into XR-compatible formats before construction begins. The system pre-loads relevant data into the XR device, so that when the worker arrives at a construction location, the information is immediately available for display without requiring time-consuming data retrieval or processing during construction
Solution Approach 2:
The patent enables rapid information delivery by directly projecting essential construction data onto the XR display unit without requiring workers to manually search through blueprints or consult multiple reference materials. The system quickly presents only the relevant information needed for the current construction task, allowing workers to skip unnecessary information-gathering steps and proceed directly to construction activities
3Measurement precision
If sensor unit recognizes ID codes to detect construction position, then measurement precision improves, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The patent uses ID codes as simplified copies or representations of complex construction target information. Instead of requiring the sensing unit to directly measure and interpret complex spatial coordinates or geometric features of construction elements, the system uses easily recognizable ID codes (visual markers, RFID tags, or digital identifiers) that serve as proxies for the actual construction targets, enabling precise positioning through simple code recognition rather than complex measurement
Data Source
AI summary
Disclosed is an apparatus for improving construction precision based on extended reality (XR). At least one piece of XR content related to a construction target positioned in front inside a construction site is displayed on a display unit. When a construction position of a construction object included in the construction target is determined, the XR content including the design information of the construction object at the construction position is displayed on the display unit.
