Smart Display Control Authority Switching via Mediator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart displays face performance issues due to conflicts in control flow between external and internal hosts, leading to delays in switching control authority over the panel and peripherals, affecting user satisfaction.
Innovation Solution
A smart display system with a communication interface, internal host, video module, and switch that adjusts operation modes based on connection status with the external host, allowing seamless switching of control authority over peripherals and video data sources between internal and external hosts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smart display operates with both external host and internal host independently, then the display provides more functionality and versatility, but control conflicts occur between the two hosts when switching control authority
Solution Approach 1:
The patent introduces a mediator mechanism that manages control authority between the external host and internal host. The mediator monitors connection status and coordinates the switching of control rights, preventing conflicts by ensuring only one host controls the display at a time. This intermediary layer resolves the contradiction by maintaining system reliability while preserving the versatility of having both hosts available.
2Adaptability or versatility
If the internal host and external host switch control authority, then the smart display can adapt to different usage scenarios, but delays occur in switching control authority affecting user satisfaction
Solution Approach 1:
The patent implements preliminary action by pre-establishing the mediator mechanism that is ready to manage control transitions. The mediator continuously monitors connection status and maintains readiness to transfer control authority immediately when switching conditions are met. This preliminary preparation eliminates delays during actual control switching, allowing seamless transitions between external and internal host control modes.
3Extent of automation
If the smart display operates independently with internal host, then the display provides smart functions and peripherals, but control conflicts arise when external host connection status changes
Solution Approach 1:
The patent employs feedback mechanisms where the mediator continuously monitors the connection status between the external host and display. When connection status changes, the mediator receives feedback and automatically adjusts control authority accordingly. This feedback loop ensures smooth transitions and maintains ease of operation by preventing control conflicts, allowing the display to seamlessly switch between independent smart operation and external host-controlled mode.
