Adjustable Fixing Device for Display Inspection Instrument Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inspecting display visual quality, such as using luminance and color difference meters, face challenges with instability due to varying distances and heights between the measuring instrument and the display, leading to inconsistent results and difficulties in adjusting for different display sizes and positions.
Innovation Solution
A device with a fixed frame unit removably mounted to the display, featuring a moving frame that can be raised and lowered, and an elevating unit to adjust the measuring instrument's position, maintaining a constant distance and allowing for flexible positioning to accommodate various display sizes and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the measuring instrument is held manually or mounted on a tripod, then the inspection can be performed, but the distance between the measuring instrument and the display varies, leading to unstable inspection results
Solution Approach 1:
A fixing device is introduced as an intermediary between the display and the measuring instrument. This device includes a fixing frame that attaches to the display and a positioning mechanism that holds the measuring instrument at a predetermined distance, thereby stabilizing the inspection process while maintaining ease of operation
Solution Approach 2:
The fixing device allows adjustment of the measuring instrument's position parameters (distance and angle) to optimal values. By changing these parameters to fixed, predetermined values, the inspection reliability is improved while the adjustment mechanism maintains operational ease
2Reliability
If the measuring instrument position is fixed, then inspection stability is improved, but the device cannot adapt to different display sizes and positions
Solution Approach 1:
The fixing device incorporates dynamic adjustment mechanisms that allow the measuring instrument's position and orientation to be adjusted according to different display sizes and positions. Once adjusted, the position is fixed to maintain stability during inspection, thus achieving both reliability and adaptability
Solution Approach 2:
The fixing device is designed with universal mounting capabilities that can accommodate various display sizes and positions. The device includes adjustable components and multiple mounting options, enabling it to adapt to different inspection scenarios while maintaining stable measurement conditions
3Ease of operation
If a tripod is used to mount the measuring instrument, then hands-free operation is achieved, but the tripod position cannot be maintained constant, causing variation in inspection conditions
Solution Approach 1:
The fixing device is segmented into a stable base that attaches to the display and a separate positioning mechanism for the measuring instrument. This segmentation allows the base to provide stable, fixed positioning while the positioning mechanism enables hands-free operation and adjustment, resolving the contradiction between stability and ease of operation
