Embedding QR Codes in Lighting Ground Plans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commissioning methods for lighting systems are inefficient due to inaccurate and insufficient device information on ground plans, leading to increased effort and costs during installation and setup.
Innovation Solution
A system and method that generates and embeds machine-readable codes, such as QR codes, within ground plans to provide device information, allowing for easy access and acquisition of necessary details for commissioning devices, including device type, address, and connection information, using a processor and commissioning device with sensors to decode and transmit this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional commissioning methods are used with manual ground plans, then device information can be provided, but the information is inaccurate and insufficient leading to increased effort and costs
Solution Approach 1:
The patent uses machine-readable codes (QR codes, barcodes) as copies of device information that can be automatically read and processed. Instead of manually transcribing device details from ground plans to commissioning software, the system creates machine-readable representations of device data that commissioning devices can scan and automatically import, eliminating manual copying errors and reducing commissioning time
Solution Approach 2:
The patent replaces manual mechanical processes (handwriting device information on ground plans, manual data entry into commissioning tools) with automated optical/electronic systems. Machine-readable codes replace handwritten or printed device information, and automated scanning replaces manual data transcription, significantly improving accuracy and reducing commissioning effort
2Measurement precision
If machine-readable codes are embedded in ground plans to provide device information, then commissioning accuracy is improved, but the complexity of the ground plan system increases
Solution Approach 1:
The patent makes the ground plan system multi-functional by integrating device information storage, positioning, and identification into a single machine-readable code. The same code that marks device location also encodes device type, address, and commissioning data, eliminating the need for separate documentation systems and reducing overall system complexity despite adding codes to the ground plan
Solution Approach 2:
The machine-readable code acts as an intermediary between the ground plan and the commissioning device. Instead of requiring direct manual interpretation of complex ground plan symbols and notes, the code provides a standardized interface that automatically translates visual information into structured device data, simplifying the commissioning process
3Productivity
If comprehensive device information is provided for each device, then commissioning efficiency is improved, but the amount of information to be managed increases
Solution Approach 1:
The patent segments device information into structured fields within machine-readable codes (device type, address, location coordinates, commissioning parameters). This segmentation allows the commissioning device to selectively read and process only the specific information needed for each commissioning task, managing large volumes of information efficiently without overwhelming the operator
