Display System Intermediary Signal Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems struggle to control multiple display devices when some devices cannot communicate switch signals with each other, limiting the ability to switch images seamlessly between information processing devices.
Innovation Solution
A display system comprising first and second information processing devices and display devices, where the second information processing device outputs a switch signal to the first display device, and the first information processing device outputs a corresponding switch signal to the second display device, enabling image switching even if direct communication between the second display device and information processing device is not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication between all display devices and information processing devices is required for image switching, then communication reliability is improved, but system adaptability deteriorates
Solution Approach 1:
The first display device serves as an intermediary that receives switch signals from the second information processing device and relays them to the second display device. This mediator approach enables indirect communication paths, allowing the system to adapt to cases where direct communication between certain devices is not possible while maintaining reliable image switching functionality.
2Adaptability or versatility
If multiple direct communication channels are established between all devices, then communication coverage is improved, but device complexity increases
Solution Approach 1:
The first display device performs multiple functions: it displays images from the first information processing device, receives switch signals from the second information processing device, and relays these signals to the second display device. This multi-functionality reduces the need for separate dedicated communication channels between all device pairs, thereby reducing overall system complexity while maintaining comprehensive communication coverage.
