Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement technologies (lasers, lidar, measuring tapes) are used to map lighting fixtures, then measurement precision can be achieved, but the commissioning process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical measurement tools (lasers, lidar, measuring tapes) with an automated image processing system. The system uses a mobile device camera to capture images of lighting fixtures, then automatically processes these images through software algorithms to extract fixture locations and convert them to physical coordinates, eliminating the need for manual measurement while maintaining mapping accuracy
Solution Approach 2:
The patent creates a digital copy of the physical space by capturing images of lighting fixtures and processing them to generate a mapped representation. The image processing system creates a digital model of fixture locations from visual data, replacing the need for physical measurement and manual data entry processes
2Productivity
If automated image processing is used to identify lighting fixtures, then productivity and ease of operation improve, but the complexity of the system increases
Solution Approach 1:
The patent employs a mobile device that serves multiple functions: it acts as an image capture device to photograph lighting fixtures, functions as a computing platform to process images and perform coordinate conversions, and serves as a mapping system to generate the final fixture location data. This multi-functionality increases productivity while managing system complexity by utilizing an existing versatile device
Solution Approach 2:
The patent introduces software as an intermediary between the captured images and the final mapped coordinates. The image processing software acts as a mediator that automatically extracts fixture locations from images and converts them to physical coordinate systems, bridging the gap between visual data and spatial information without requiring direct manual intervention
Data Source
AI summary
System and methods and computer program code are provided to perform a commissioning process comprising capturing, using an image capture device, an image of an area containing at least a first fixture, identifying location and positioning information associated with the image, performing image processing of the image to identify a location of the at least first fixture in the image, and converting the location of the at least first fixture in the image into physical coordinate information associated with the at least first fixture.
