Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple operating systems are installed and manually configured by the user, then the terminal device can support different operating systems, but the relationships of respective operations become chaotic and power consumption increases

Engineering Contradiction:

Improvesupport for multiple operating systemsVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The terminal device automatically detects usage scenarios and switches between operating systems without user intervention. The system monitors scenario changes and autonomously determines which operating system to activate, eliminating the need for manual configuration while optimizing power consumption based on actual usage patterns

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The operating system selection is made dynamic and adaptive rather than static. The system continuously monitors usage scenarios and adjusts the active operating system in real-time, allowing the terminal to transition between different operating systems based on current needs, thereby reducing power consumption when high-performance features are not required

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple operating systems are installed and manually configured by the user, then the terminal device can support different operating systems, but the coordination of operations is reduced

Engineering Contradiction:

Improvesupport for multiple operating systemsVSAvoidcoordination of operations

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements a feedback mechanism where usage scenarios are continuously monitored and analyzed. Based on this feedback, the terminal automatically adjusts which operating system is active, ensuring optimal coordination of operations. The system learns from usage patterns and makes intelligent decisions about operating system selection, improving operational coordination without user intervention

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The terminal device autonomously manages operating system selection and coordination based on detected usage scenarios. The system self-adjusts the active operating system according to current usage patterns, eliminating the need for manual coordination while maintaining smooth operation transitions and proper system coordination

Inventive Principle:

Principle #25Self-service

3Productivity

If the first operating system runs in normal operating state, then full functionality is available, but power consumption is greater compared to the second operating system

Engineering Contradiction:

Improveoperational functionalityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system dynamically selects between operating systems based on usage scenario requirements. When high-performance functionality is needed, the first operating system is activated; when lower performance requirements are sufficient, the second operating system is used. This dynamic switching optimizes the balance between productivity and power consumption based on real-time usage patterns

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters by switching between different operating systems with different power consumption characteristics. The first operating system provides full functionality with higher power consumption, while the second provides adequate functionality with lower power consumption. The system adjusts which parameter set is active based on scenario requirements

Inventive Principle:

AI summary

A mode switching method, a mode switching apparatus, a terminal device, and a storage medium are provided. A first operating system and a second operating system are at least installed in the terminal device. A power consumption of the first operating system in a normal operating state is greater than that of the second operating system. The method includes: if a scenario change notification for the terminal device is received, obtaining target scenario information corresponding to a changed scenario; and in response to the target scenario information meeting a mode switching condition corresponding to the scenario change notification, switching the terminal device from the current operating mode that is currently in operation to a target operating mode. The operating state and the operating power consumption of the first operating system in the current operating mode are different from those of the first operating system in the target operating mode.
