Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital signage systems face issues with screen distortion due to level differences between adjacent display panels, leading to installation challenges and increased time and cost.
Innovation Solution
A multi-display device installation system and method that uses a step adjusting module and sensor modules to automatically adjust the level difference between display modules, ensuring uniform horizontal levels and minimizing equipment costs by allowing repeated use of the step adjusting and sensor modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display panels are installed adjacent to each other without level adjustment, then installation process is simple and fast, but screen distortion occurs due to step differences between panels
Solution Approach 1:
A step adjusting module is introduced as an intermediary component between the display panel and the mounting bracket. This module includes an adjusting screw that can be rotated to change the vertical position of the display panel, thereby eliminating step differences between adjacent panels without requiring complex installation procedures
Solution Approach 2:
The installation system incorporates self-adjustment capabilities through the step adjusting module, which allows installers to independently adjust each display panel's level without requiring external equipment or complex procedures. The module enables self-leveling through simple rotational adjustment of the adjusting screw
2Productivity
If manual level adjustment methods are used, then equipment cost is low, but installation time increases and adjustment precision decreases
Solution Approach 1:
A sensor module is integrated into the step adjusting module to provide real-time feedback on the vertical position of the display panel. The sensor detects the level of the panel's front surface and transmits this information to a control unit, which automatically adjusts the adjusting screw to achieve precise level consistency between adjacent panels
Solution Approach 2:
The manual mechanical adjustment process is replaced with an automated electro-mechanical system. The control unit receives sensor feedback and automatically controls the adjusting screw mechanism, eliminating the need for manual measurement and adjustment while improving both speed and precision
3Manufacturing precision
If step adjusting modules are designed for single use, then adjustment precision is high, but equipment cost increases due to inability to reuse
Solution Approach 1:
The step adjusting module is designed to be reusable rather than disposable. After the display panels are installed and leveled, the sensor module can be removed and reused for adjusting other panels, while the step adjusting module remains integrated into the installation system for potential future adjustments or maintenance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents screen distortion by automatically adjusting the level difference between adjacent display modules, reducing installation time and minimizing additional equipment costs through the repeated use of the step adjusting and sensor modules.
