Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen display area is increased to provide better user experience and support mobile web applications, then the display capability is improved, but the power consumption increases significantly
Solution Approach 1:
The patent divides the physical screen into multiple virtual screens, each serving different functions or applications. By segmenting the display area, the system can activate only the necessary virtual screens based on current usage needs, rather than keeping the entire high-resolution screen active, thus reducing overall power consumption while maintaining display versatility.
Solution Approach 2:
The patent applies different display qualities and resolutions to different regions of the screen. By configuring virtual screens with appropriate resolution and brightness levels according to their specific functions, the system optimizes power consumption locally rather than uniformly across the entire screen, achieving energy efficiency without sacrificing essential display quality.
2Use of energy by moving object
If the working frequency and voltage of the chip are reduced to lower power consumption, then the energy efficiency is improved, but the processing performance deteriorates
Solution Approach 1:
The patent implements dynamic power management by adjusting the working frequency and voltage of the chip based on real-time system conditions and usage patterns. When virtual screens are activated, the system dynamically scales processor performance to match the computational demands of each virtual screen, avoiding both over-provisioning and under-provisioning, thus optimizing the balance between power consumption and processing performance.
3Use of energy by moving object
If the screen luminance is automatically adjusted using external photosensitive devices to reduce power consumption, then the energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service power management where the system automatically monitors usage patterns, application states, and environmental conditions to dynamically adjust virtual screen configurations without requiring external photosensitive devices or complex user intervention. The system serves itself by making intelligent decisions about which virtual screens to activate and at what resolution, reducing both power consumption and device complexity.
4Use of energy by moving object
If the code of the software system is optimized to reduce calculation complexity and achieve power consumption optimization, then the energy efficiency is improved, but the development complexity increases
Solution Approach 1:
The patent optimizes power consumption by dynamically changing software parameters such as screen resolution, refresh rate, and rendering quality based on virtual screen usage. Instead of optimizing code complexity, the system adjusts operational parameters at runtime to match computational demands, achieving energy efficiency through parameter optimization rather than code restructuring, thus avoiding increased software development complexity.

AI summary
A method, system and computer program product for saving power for a mobile terminal. Configuration parameters of a first virtual screen are obtained in response to the occurrence of a first trigger event, where the first virtual screen is at least part of the screen of the mobile terminal. The scope of the first virtual screen is determined according to the configuration parameters of the first virtual screen. Data to be displayed on the screen of the mobile terminal is displayed within the determined scope of the first virtual screen. The display of the screen of the mobile terminal is closed outside the determined scope of the first screen. By realizing a virtual screen and using only part of the screen of the mobile terminal for displaying, there is a reduction in the power consumed by the screen display so that the battery life of the mobile terminal is improved.
