Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminance measurement methods require multiple workers, are time-consuming, and prone to measurement errors due to the need for manual data recording and the limitations of measuring illuminance over a wide range, such as in sports fields, where lighting time is restricted.
Innovation Solution
An illuminance measuring system comprising a moving vehicle with an illuminance measuring instrument, a position measuring unit, and a data collector that automatically moves to predetermined points, using GPS and laser surveying instruments to track positions and collect data, reducing the need for manual intervention and enabling efficient three-dimensional illuminance distribution mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used with multiple workers, then measurement can be performed at multiple points, but measurement time increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical measurement operations with an automated system comprising a moving vehicle, illuminance measuring instrument, position measuring means, and data collector. The system automatically moves to predetermined measuring points, measures illuminance, records positions, and stores data without manual intervention, thereby maintaining measurement coverage while dramatically improving efficiency
Solution Approach 2:
The measurement system performs self-service by automatically navigating to measuring points using position information data, conducting illuminance measurements autonomously, and collecting data without requiring continuous human operation. The system serves itself by integrating movement control, measurement execution, and data collection in one automated workflow
2Loss of information
If manual data recording is performed by workers, then measurement results can be captured, but time is lost and human error may occur
Solution Approach 1:
The patent replaces manual data recording operations with automated electronic data collection and storage. The data collector automatically receives measurement results from the illuminance measuring instrument and position information from the position measuring means, eliminating manual transcription and reducing both time loss and human error in data recording
Solution Approach 2:
The data collector serves as an intermediary device that automatically receives and processes data from both the illuminance measuring instrument and position measuring means. This intermediary component coordinates data collection, associates measurement results with corresponding positions, and stores the integrated information, replacing the need for manual data compilation
3Area of stationary object
If measurement is performed in wide range areas with limited lighting time, then coverage is achieved, but measurement speed must increase and coordination becomes complex
Solution Approach 1:
The system performs preliminary action by pre-storing position information data of predetermined measuring points before the actual illuminance measurement. This allows the moving vehicle to automatically navigate to each measuring point without real-time human coordination, enabling efficient coverage of wide areas within limited lighting time
Solution Approach 2:
The patent employs dynamic movement of the illuminance measuring instrument by mounting it on a moving vehicle that automatically transitions between measuring points. This dynamic approach allows continuous measurement across wide areas without the coordination complexity of static multi-worker teams, maintaining high measurement speed
