Solution Overview
Problem
Conventional calibrators for display devices are cumbersome and inconvenient to use, especially in large video walls, as they require long cables and are difficult to position accurately, particularly on tilted screens.
Innovation Solution
A calibrator with a transformable absorption plate that attaches to the screen via a vacuum absorption method, featuring a rotary mechanism for precise positioning and wireless data transmission, allowing for easy attachment and detachment, and enabling calibration on tilted surfaces without the need for cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional calibrator with a cable is used on a large video wall, then the calibrator can be connected to the display device, but the cable becomes long and it becomes inconvenient to move the position of the calibrator
Solution Approach 1:
The patent removes the cable from the calibrator system entirely, extracting the data transmission function and replacing it with wireless communication. This eliminates the constraint of cable length and allows the calibrator to be freely positioned on the display device without being tethered by a physical connection.
Solution Approach 2:
The patent replaces the mechanical cable connection with a wireless communication system. The calibrator uses wireless data transmission to communicate with the display device, substituting the physical mechanical connection with an electromagnetic field-based communication method, thereby eliminating the cable and its associated movement constraints.
2Measurement precision
If a conventional calibrator is attached to a tilted screen, then the calibrator can be positioned on the screen, but it becomes difficult to position accurately and maintain stable contact
Solution Approach 1:
The patent employs a suction cup-based attachment mechanism that dynamically adapts to the screen surface. The suction cup can conform to tilted surfaces and maintain stable contact through vacuum adhesion, allowing the calibrator to be easily attached and positioned accurately on screens with various inclinations without requiring precise manual alignment.
Solution Approach 2:
The suction cup attachment mechanism enables the calibrator to self-adjust and self-stabilize on the screen surface. Once attached, the vacuum-based connection automatically maintains stable contact and positioning, reducing the need for continuous manual adjustment and ensuring accurate measurement orientation regardless of screen tilt angle.
3Productivity
If a calibrator is frequently attached and detached from the screen, then the calibrator can be repositioned, but the attachment structure may become loose or damaged
Solution Approach 1:
The suction cup attachment mechanism provides dynamic adaptability for frequent attachment and detachment operations. The vacuum-based connection can be quickly established and released without mechanical wear, maintaining reliable attachment stability even after multiple cycles of attachment and detachment, unlike rigid mechanical mounting structures that may become loose or damaged.
