Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adjustable units with multiple power statuses are integrated to provide customizable power management, then power management flexibility and adaptability are improved, but device complexity increases and accurate power consumption measurement becomes more difficult
Solution Approach 1:
The power management system is segmented into multiple independent adjustable units (display, CPU, wireless module, etc.), each with its own power status settings. This segmentation allows each component to be managed independently while maintaining overall system flexibility, resolving the contradiction by organizing complexity into manageable segments.
Solution Approach 2:
The power management device is designed to universally manage multiple types of adjustable units with different power statuses through a unified interface. The collection table structure and measurement mechanism are universal across all adjustable units, providing adaptability while maintaining systematic organization.
2Loss of information
If conventional power management mechanisms are used to display different power statuses, then basic power status information is provided, but accurate and detailed power consumption information is not provided to users
Solution Approach 1:
The system implements feedback by measuring actual power consumption for each power status collection and providing this measured information to users through the user interface. The collection table stores and retrieves measured power consumption data, enabling users to see accurate feedback on how different power status combinations affect overall power consumption.
Solution Approach 2:
The system performs preliminary measurement and storage of power consumption data for all possible power status collections in the collection table. This preliminary action enables users to access accurate power consumption information immediately without requiring real-time measurement during operation, improving both accuracy and ease of use.
3Adaptability or versatility
If users add or replace components to customize electronic products, then functionality and features are enhanced, but power consumption changes are not accurately reflected
Solution Approach 1:
The power management system is designed to dynamically adapt when components are added or replaced. The measurement device continuously monitors power consumption, and the collection table is updated to reflect new component configurations. This dynamic approach ensures measurement precision is maintained even as system customizability increases.
