Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-system electronic apparatuses face challenges in meeting user requirements due to high power consumption and poor user experience caused by hardware reset during system switching, as they cannot run two systems simultaneously without increased power consumption.
Innovation Solution
A dual-system electronic apparatus is designed with two processors, one for an open operating system and one for an encryption operating system, sharing peripheral equipment and storage, with a communication module for data interaction, allowing seamless switching between systems without rebooting, and promoting users to switch between them based on application types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hardware reset operation is performed upon system switching in existing dual-system apparatuses, then system switching can be achieved, but power consumption increases and user experience deteriorates
Solution Approach 1:
The system is segmented into two independent processing paths: a first processor handling the first operating system and a second processor handling the second operating system. This segmentation allows each processor to operate independently without requiring hardware reset during switching, thereby reducing power consumption while maintaining system switching capability.
Solution Approach 2:
The system implements dynamic switching between operating systems through a switching circuit that can rapidly transition between the first and second processors without hardware reset. This dynamic switching mechanism enables seamless system transitions, improving ease of operation while minimizing power consumption compared to static hardware reset approaches.
2Adaptability or versatility
If two systems are run simultaneously in existing dual-system apparatuses, then user requirements for application classification are met, but power consumption increases
Solution Approach 1:
Instead of continuously running both operating systems simultaneously, the system implements periodic switching between the first and second operating systems. The switching circuit alternates between processors based on application requirements, maintaining adaptability for different application types while significantly reducing power consumption compared to continuous dual-system operation.
Solution Approach 2:
The system extracts only the necessary processing power for the active operating system at any given time. When the first operating system is active, only the first processor operates; when the second operating system is active, only the second processor operates. This extraction approach maintains full functionality for application classification while eliminating the power overhead of running both systems simultaneously.
3Reliability
If hardware reset operation is performed upon system switching, then system isolation is maintained, but user experience deteriorates
Solution Approach 1:
A switching circuit acts as an intermediary between the first and second processors, enabling seamless transitions between operating systems without hardware reset. This intermediary component maintains system isolation and reliability while providing smooth switching that preserves user experience, eliminating the need for disruptive hardware reset operations.
