Wireless Peripheral Connection Switching for Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for peripheral devices, such as printers, allow only one host device to use the peripheral at a time, preventing multiple devices from utilizing the peripheral even when it is idle, thus limiting data throughput.
Innovation Solution
An information processing device with two wireless USB units that dynamically switches connections based on data processing requests, releasing connections with idle devices to prioritize active devices, ensuring that devices attempting data processing are connected preferentially, thereby increasing data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a peripheral device allows only one host device to use it at a time, then connection stability is ensured, but data throughput is limited because multiple devices cannot utilize the peripheral even when idle
Solution Approach 1:
The patent implements dynamic connection switching where the peripheral device can switch between multiple host devices based on their activity status. The system monitors whether connected host devices are actively using the peripheral and dynamically releases connections for idle devices while prioritizing connections for active devices, making the connection state flexible rather than static
Solution Approach 2:
The system changes the connection parameter from a fixed single-connection state to a dynamic multi-connection state. By monitoring usage status and changing connection parameters (connected/not connected) based on real-time conditions, the system allows multiple devices to access the peripheral simultaneously when needed, thereby increasing data throughput while maintaining connection stability for active devices
2Productivity
If a peripheral device maintains connection with multiple host devices simultaneously, then data throughput increases, but connection management complexity increases
Solution Approach 1:
The peripheral device performs self-service by automatically monitoring its own connection status and the activity status of connected host devices. The system autonomously determines which connections to maintain and which to release without requiring complex external management, thereby managing multiple connections while controlling complexity through automated status monitoring and connection control
3Reliability
If a host device takes sole possession of a peripheral device, then connection reliability is improved, but resource utilization deteriorates as other devices cannot use the peripheral when idle
Solution Approach 1:
The peripheral device is designed with multi-functionality to serve multiple host devices. By implementing the capability to connect with and serve multiple hosts simultaneously based on their needs, the peripheral becomes universal rather than dedicated to a single device, thereby improving resource utilization while maintaining reliable connections for active devices through status monitoring
