Solution Overview
Problem
Conventional large screen displays require manual programming of slave display units, which is time-consuming and impractical, especially when rearrangements occur.
Innovation Solution
A master display unit equipped with sensing elements and control units that automatically identify and communicate with slave units, allowing for automatic configuration and reduced setup time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual programming is used to configure slave display unit locations, then the system can be configured, but the configuration process becomes time-consuming and impractical
Solution Approach 1:
The slave display units automatically identify themselves and determine their own locations through sensing elements that detect the master display unit and other slave units. This self-configuration eliminates the need for manual programming, allowing the system to configure itself automatically when powered on or rearranged.
Solution Approach 2:
The sensing elements and identification features are pre-configured in the display units before deployment. When the system is assembled or rearranged, these pre-configured elements automatically perform the location identification and configuration tasks without requiring manual intervention, thus saving time.
2Reliability
If manual programming is required for each slave display unit, then location configuration is possible, but the complexity and difficulty of setup increases
Solution Approach 1:
Each slave display unit is equipped with sensing elements that automatically detect the positions of the master display unit and other slave units. The units self-configure their locations and display content accordingly, eliminating the need for complex manual programming while maintaining accurate location configuration.
Solution Approach 2:
The manual mechanical process of programming and setting locations is replaced by an automatic sensing and detection system. The sensing elements electronically detect positions and transmit this information to control the display units, substituting manual operations with automated electronic detection and control.
3Adaptability or versatility
If display units are rearranged, then flexibility is improved, but manual reconfiguration is required which increases time consumption
Solution Approach 1:
The system is designed to be dynamically reconfigurable. When display units are physically rearranged, the sensing elements automatically detect the new positions and the system dynamically adapts the configuration without requiring manual reprogramming, thus maintaining flexibility while saving reconfiguration time.
Solution Approach 2:
After rearrangement, the slave display units automatically sense their new locations and self-reconfigure to display the appropriate content for their new positions. This self-adaptation capability allows the system to accommodate rearrangements without manual intervention, preserving flexibility and eliminating reconfiguration time loss.
