Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in obtaining location information of light source assemblies, particularly those positioned at vertices or outermost sides of display devices, especially when some assemblies are not activated, and in adjusting luminance or color temperature of these assemblies.
Innovation Solution
A control device that utilizes a camera and controller to activate specific light source assemblies at vertices, calculate their positions, and adjust luminance or color temperature by analyzing images captured by a general camera, even if some assemblies are not activated, using stored reference values for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera captures images to detect light source assembly locations, then location information can be obtained, but vertex light source assemblies may not be activated causing detection failure
Solution Approach 1:
The system performs preliminary activation of vertex light source assemblies before image capture to ensure they are operational and visible for detection. This preliminary action ensures that the vertex assemblies are ready for detection and prevents detection failure due to non-activation.
Solution Approach 2:
The system uses image capture and analysis to obtain feedback on light source assembly locations, then uses this information to adjust and optimize the detection process. The feedback loop ensures continuous improvement of location detection accuracy and reliability.
2Measurement precision
If vertex light source assemblies are activated for detection, then location information can be obtained, but energy consumption increases
Solution Approach 1:
The system segments the light source assemblies into vertex assemblies and non-vertex assemblies, activating only the vertex assemblies for detection purposes. This segmentation reduces overall energy consumption while maintaining the ability to obtain accurate location information.
Solution Approach 2:
The system applies partial action by activating only the necessary vertex light source assemblies rather than all assemblies, achieving sufficient detection capability with reduced energy consumption.
3Loss of information
If all light source assemblies are activated for detection, then complete location information is obtained, but device complexity increases
Solution Approach 1:
The system extracts and focuses on detecting only the vertex light source assemblies, which are sufficient for obtaining complete location information. This extraction approach reduces control complexity by eliminating the need to manage and detect all light source assemblies.
Solution Approach 2:
The system uses partial action by detecting only the necessary vertex assemblies rather than all assemblies, achieving complete location information with reduced operational complexity.
