Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching between devices for online services, as communication sessions are terminated, requiring recreation of tasks and processes.
Innovation Solution
An online service access control method and apparatus that determines a device with control rights among multiple user devices based on priorities, access time, type, user selection, or performance, allowing seamless data relay and state management across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user logs into an online service account on multiple devices, then the user can access the service from any device, but the communication session between the existing device and server is terminated, causing inconvenience
Solution Approach 1:
The system segments the control of online services by designating one device as having 'control right' while allowing other devices to access the service without control rights. This segmentation allows multiple devices to connect simultaneously without terminating each other's sessions, resolving the contradiction between multi-device access and session continuity
Solution Approach 2:
The server acts as an intermediary that manages control rights and session states across multiple devices. By introducing this intermediary layer, the system can track which device has control right and maintain appropriate sessions for each device, enabling both multi-device access and session continuity
2Ease of operation
If the system allows multiple devices to access the same account simultaneously, then user convenience is improved, but determining which device should have control right becomes complex
Solution Approach 1:
The system changes the parameter of control right assignment by using clear criteria such as most recent access time, device type priorities, or user-defined preferences. This parameter-based approach simplifies the complexity of determining control right among multiple devices while maintaining concurrent access capability
3Device complexity
If the system terminates communication sessions when switching devices, then resource management is simplified, but user experience deteriorates due to lost tasks and processes
Solution Approach 1:
The system maintains continuity of useful action by preserving the control device's session state even when other devices access the account. The control device continues its tasks and processes uninterrupted, eliminating the need for task recreation while allowing flexible multi-device access
Solution Approach 2:
The system performs preliminary action by pre-designating a control device before switching occurs. This advance designation ensures that when device switching happens, the control device's session state is already preserved and ready to continue, preventing loss of tasks and processes
