Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General-purpose computing devices face inefficiencies when used for limited-purpose applications due to lengthy boot-up processes, power consumption, complexity, and hardware requirements, with existing solutions being costly, difficult to implement, or requiring hardware changes.
Innovation Solution
A system and method that allows a general-purpose computing device to load a limited-purpose operating system into memory, using a partition with both general-purpose and limited-purpose operating systems, where the limited-purpose OS is configured to provide restricted capabilities and is loaded under control of the general-purpose OS, utilizing a virtual drive for quick boot-up and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a general-purpose computing device is used for limited-purpose applications, then the device can perform a wide range of functions, but the boot-up process becomes lengthy and power consumption increases
Solution Approach 1:
The patent divides the computing device into two distinct operational modes: a full general-purpose mode with complete operating system functionality, and a limited-purpose mode with a streamlined subset of functions. This segmentation allows the device to load only the necessary components for the current task, significantly reducing boot-up time while maintaining versatility when needed.
Solution Approach 2:
The system dynamically switches between different operational configurations based on the current task requirements. The computing device can transition from a full OS environment to a limited-purpose environment on-demand, adapting its functionality to match the user's immediate needs without requiring a complete reboot or hardware change.
2Adaptability or versatility
If a general-purpose computing device is used for limited-purpose applications, then the device can perform multiple tasks, but system complexity and potential conflicts increase
Solution Approach 1:
The patent segments the system into a core essential function set and optional additional functions. By separating the limited-purpose core from the full general-purpose capabilities, the system reduces complexity for routine tasks while preserving the ability to access full functionality when required, thereby minimizing conflicts and glitches during normal operation.
3Ease of operation
If the computing device is left running at all times to provide all capabilities, then all functions are immediately available, but energy is wasted
Solution Approach 1:
The system implements dynamic power management by transitioning between active and low-power states based on usage patterns. When the device is shut down or in standby, it can quickly restore the limited-purpose environment without a full reboot, providing near-immediate availability for common tasks while consuming minimal power during idle periods.
Solution Approach 2:
The device performs preliminary loading of the limited-purpose operating system components into memory during shutdown or standby states. This preliminary action ensures that when the device is powered on again, the essential functions are already prepared and can be activated rapidly, balancing immediate availability with energy conservation.
4Loss of time
If a limited-feature OS is loaded by selecting an alternative operating system stored in flash ROM, then boot-up time is reduced, but hardware design must change and upgrading becomes difficult
Solution Approach 1:
Instead of creating dedicated hardware for limited-purpose operations, the patent creates a software copy or subset of the operating system that resides in the existing storage memory. This virtual limited-purpose OS is loaded into memory and executed as a simplified environment, achieving fast boot-up without modifying the hardware architecture or complicating manufacturing.
Solution Approach 2:
The system uses a single universal hardware platform that can support both the full general-purpose operating system and the limited-purpose environment. By making the hardware universal and the software configurable, the system avoids the need for specialized hardware designs while still achieving rapid boot-up for limited functions through intelligent software loading.
