Image Display Device Flow Rate Sensor Wind Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices fail to accurately reflect wind information due to a significant distance between wind information detection devices and LED panels, resulting in a mismatch between the sensed wind state and the displayed information.
Innovation Solution
An image display device is designed with a physical quantity detection unit and a display body where the image is projected to include the position of the detection unit, allowing the image to change corresponding to measured value changes, ensuring accurate representation of physical quantity changes, such as wind speed, on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the distance between the wind information detection device and the LED panel is increased to cover a larger area, then the coverage area is improved, but the measurement precision deteriorates because accurate wind information is not reflected on the display
Solution Approach 1:
The display body is divided into multiple regions, with a separate physical quantity detection unit assigned to each region. This segmentation allows each detection unit to accurately measure wind information for its specific local area, eliminating the accuracy loss that would occur with a single distant detection device covering the entire area.
Solution Approach 2:
Each region of the display body has its own dedicated detection unit positioned close to it, ensuring that the detection characteristics are optimized for local measurement. This local quality approach ensures high measurement precision for wind information in each specific region while collectively covering the entire display area.
2Measurement precision
If the distance between the physical quantity detection unit and the display position is reduced to improve measurement accuracy, then the measurement precision is improved, but the area of the display body that can be covered deteriorates
Solution Approach 1:
The display body is divided into multiple regions, with a separate physical quantity detection unit assigned to each region. This segmentation allows each detection unit to accurately measure wind information for its specific local area, eliminating the accuracy loss that would occur with a single distant detection device covering the entire area.
Solution Approach 2:
Multiple detection units are arranged to work together as a unified system, with each unit serving its local region while collectively providing comprehensive coverage of the entire display area. This multi-functionality approach allows the system to maintain high measurement precision at each location while achieving broad area coverage through the coordinated operation of multiple detection units.
