Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection and calibration colorimeter modules often fail to accurately detect and calibrate display device colors due to incorrect positioning or proximity to the display surface, leading to inaccurate results.
Innovation Solution
A light detection module with a shaft and rod configuration that allows switching between modes, enabling accurate detection of display surface features by adjusting the angle between the shaft and rod portions to ensure the detector can reach the central area without obstructing the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is manually attached to the display screen and rotated to face the display area, then the detection accuracy is improved, but the operation complexity and time consumption increase
Solution Approach 1:
The light detection module employs a rotatable rod portion that can dynamically adjust its orientation. The rod portion rotates around the shaft portion to change the detection surface orientation from facing away from the display surface (first mode) to facing the display surface (second mode). This dynamic adjustment eliminates manual attachment and rotation operations while maintaining detection accuracy.
2Measurement precision
If the detection module is positioned close to the display surface, then the detection precision is improved, but the module may obstruct the user's view of the display
Solution Approach 1:
The rod portion's rotatable design allows the detection module to dynamically switch between two operational modes. In the first mode, the detection surface faces away from the display surface, positioning the module away from the viewing area to avoid obstruction. In the second mode, the rod rotates to bring the detection surface facing the display surface for accurate detection. This dynamic configuration resolves the contradiction between detection precision and view obstruction.
3Device complexity
If the detection module is fixed in one position, then the device complexity is reduced, but the adaptability to different detection modes decreases
Solution Approach 1:
The light detection module incorporates a simple yet effective rotational mechanism where the rod portion can rotate around the shaft portion. This dynamic structure enables the module to switch between two distinct operational modes: first mode with the detection surface facing away from the display surface, and second mode with the detection surface facing the display surface. The rotational design provides adaptability without significantly increasing device complexity.
