Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the computing device switches to maximum battery life mode, then battery life is extended, but the user loses transparency about which components are sacrificed and how power saving is achieved
Solution Approach 1:
The system provides continuous feedback to the user about which power-saving techniques are active and their impact on device components. The UI displays real-time information about sacrificed features (e.g., reduced display refresh rate, lowered CPU performance) corresponding to each power-saving mode, enabling informed user decisions while extending battery life.
2Use of energy by moving object
If power-saving techniques are applied to extend battery life, then energy consumption is reduced, but device performance and functionality are compromised
Solution Approach 1:
The system dynamically adjusts device performance parameters based on selected power-saving modes. When a user chooses to extend battery life, the system automatically modifies CPU frequency, display refresh rates, and other performance parameters in real-time, allowing flexible trade-offs between power consumption and productivity based on current user needs.
Solution Approach 2:
The system changes operational parameters of device components to achieve power savings. Specific parameters such as display brightness, CPU clock speed, GPU rendering quality, and network transmission power are adjusted according to the selected power-saving technique, enabling quantitative control over the balance between energy consumption and performance.
3Adaptability or versatility
If multiple power-saving options are provided to users, then user choice and control are improved, but system complexity increases
Solution Approach 1:
The system segments power-saving options into distinct, manageable modes (e.g., moderate power saving, aggressive power saving, maximum battery life). Each mode bundles specific power-saving techniques together, presenting users with simplified choices rather than requiring them to configure individual parameters. This segmentation reduces perceived complexity while maintaining adaptability.
