OS Switching Controller for Peripheral Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual operating system architectures face conflicts during switching, leading to initialization failures and system crashes due to conflicting system commands and settings from competing operating systems when one OS is in a sleep state.
Innovation Solution
Implementing a controller that intercepts and prevents setting commands from the first operating system when switching to the second OS, and uses synchronization managers to ensure only one OS controls peripheral devices, with an optional response table to simulate device responses for smooth switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual operating systems are integrated into a single electronic device to take advantage of both systems, then the versatility and functionality of the device is improved, but system conflicts and initialization failures occur when switching between operating systems
Solution Approach 1:
A controller is introduced as an intermediary component between the first operating system, second operating system, and peripheral devices. The controller intercepts setting commands from the inactive operating system and prevents them from reaching peripheral devices, thereby mediating the interaction between dual operating systems and eliminating conflicts during switching.
2Use of energy by moving object
If the first operating system remains in sleep state while second operating system is activated, then resource sharing is improved, but the first operating system continues to send setting commands causing conflicts
Solution Approach 1:
The controller acts as a mediator that receives setting commands from the first operating system in sleep state and intercepts them before they reach peripheral devices. This allows the first OS to remain in low-power sleep state while preventing its commands from conflicting with the active second OS.
Solution Approach 2:
The controller proactively intercepts and blocks setting commands from the inactive operating system before they can execute and cause conflicts. This preliminary anti-action prevents potential initialization failures and system crashes before they occur.
3Ease of operation
If setting commands from inactive operating system are allowed to reach peripheral devices, then the inactive OS maintains its operational readiness, but initialization failures and system crashes occur
Solution Approach 1:
The controller serves as an intermediary that selectively blocks setting commands from the inactive operating system while allowing commands from the active operating system to pass through. This ensures reliable peripheral device initialization by the active OS without interference from the inactive OS.

AI summary
A method for switching between dual operating systems for an electronic device installed with at least two operating systems is provided. The method includes the steps of: activating and operating a first operating system, wherein the first operating system initializes at least one peripheral device; switching to and activating a second operating system; preventing the first operating system from issuing a setting command to the peripheral device when the first operating system is switched to the second operating system; and enabling the second operating system to obtain the control right of the peripheral device to initialize the peripheral device.
