WebSocket Gateway for Seamless Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for technology that allows convenient communication and control between applications running on different devices, such as smartphones and smart TVs, to facilitate seamless interaction without requiring separate operation of each device.
Innovation Solution
An electronic device with a controller comprising an application processor and a network processor, connected to a companion device via a communication unit, where the network processor, potentially functioning as a WebSocket server, establishes and manages connections between the devices, enabling data exchange and inter-application communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates a smart TV separately to execute an application, then the application can be run on the smart TV, but the operation process becomes inconvenient and complex
Solution Approach 1:
The patent introduces a gateway server as an intermediary between the smartphone and smart TV. The gateway server receives connection requests from the smartphone, manages the connection establishment, and facilitates communication between the two devices. This mediator approach allows the smartphone to remotely control the smart TV without requiring the user to manually operate the TV's interface, thereby improving ease of operation while reducing the time needed to execute applications across devices.
2Adaptability or versatility
If multiple devices are operated separately for application execution, then device functionality is maintained, but user convenience deteriorates
Solution Approach 1:
The patent merges the control operations of multiple devices into a unified interaction model. The smartphone and smart TV are connected through the gateway server, allowing the user to control both devices through a single interface on the smartphone. This combining of device operations maintains the individual functionality of each device while significantly improving user convenience by eliminating the need to separately operate each device's interface.
3Productivity
If direct connection between application processor and companion device is established, then communication efficiency improves, but connection management complexity increases
Solution Approach 1:
The gateway server serves as an intermediary that simplifies connection management while maintaining efficient communication. Instead of requiring the application processor to directly manage complex connection protocols with the companion device, the gateway server handles the connection establishment, authentication, and data routing. This approach maintains communication efficiency by providing a dedicated communication path while reducing the complexity burden on the application processor.
4Extent of automation
If network processor manages all connections, then connection control improves, but processing load on application processor decreases
Solution Approach 1:
The patent segments the processing responsibilities between the network processor and application processor. The network processor handles connection management, authentication, and communication protocol handling, while the application processor focuses on executing the actual application logic. This segmentation automates connection control through the network processor while reducing the processing load on the application processor, as it no longer needs to manage communication protocols and connection states.
