Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple outlet strips are used to charge multiple digital electronic devices simultaneously, then charging efficiency is improved, but the electricity distribution system may be overloaded
Solution Approach 1:
The system dynamically adjusts the charging configuration by automatically generating different charge schedules based on real-time current measurements. The charge control unit activates or deactivates specific outlet strips according to the generated schedules, enabling flexible adaptation to varying power demands without manual intervention.
Solution Approach 2:
The system changes operational parameters by measuring actual current values at each outlet strip and using these measurements to generate optimized charging schedules. This parameter-based approach allows the system to adjust which outlet strips are active in each schedule, ensuring total current remains within safe thresholds while maximizing charging efficiency.
2Reliability
If multiple charge cycles are used to charge all devices, then current overload is avoided, but charging time increases
Solution Approach 1:
The system performs preliminary current measurements at all outlet strips before generating charging schedules. By measuring current values in advance and using this data to create optimized schedules, the system prepares the charging configuration beforehand, enabling efficient multi-strip charging without exceeding current thresholds.
Solution Approach 2:
The system ensures continuous charging operation by generating multiple charge schedules that collectively enable all outlet strips to charge within a single charge cycle. Each schedule activates specific outlet strips based on current measurements, maintaining continuous useful charging action without interruption or unnecessary delays.
3Reliability
If manual configuration is required to manage current thresholds, then system control is achieved, but operational complexity increases
Solution Approach 1:
The system performs self-service by automatically measuring current values at each outlet strip, generating optimized charging schedules, and activating appropriate outlet strips without any manual user configuration. The charge control unit independently manages the entire charging process, eliminating operational complexity for users.
Solution Approach 2:
The system implements feedback by measuring actual current values at each outlet strip and using this measured data to generate appropriate charging schedules. This feedback loop enables the system to automatically adjust which outlet strips are active in each schedule, ensuring current threshold compliance without manual intervention.
4Reliability
If only one outlet strip charges at a time, then current overload is prevented, but charging efficiency decreases
Solution Approach 1:
The system segments the charging process into multiple charge schedules, where each schedule activates specific outlet strips based on current measurements. This segmentation allows multiple outlet strips to charge simultaneously in different schedules within a single charge cycle, improving overall charging efficiency while preventing current overload through intelligent scheduling.
Solution Approach 2:
The system dynamically determines which outlet strips to activate in each charge schedule based on measured current values. This dynamic approach enables the system to maximize the number of simultaneously charging outlet strips in each schedule while ensuring total current remains within safe thresholds, thereby improving charging efficiency without causing overload.

AI summary
A charging device for commonly charging multiple digital electronic devices has a housing, a charge control unit and multiple outlet strips. The charge control unit is mounted inside the housing and has multiple relays. The outlet strips are electrically connected to the charge control unit with each outlet strip electrically connected to one of the relays. A charging method corresponding to the charging device is performed by the charge control unit without the need of users' configuration during a charge cycle. The charge method automatically determines if the outlet strips can simultaneously supply power to charge during each charge schedule of the charge cycle. At least one outlet strip supplies power to charge during each charge schedule, and each outlet strip supplies power to charge once, thereby achieving optimization for the charging process with automatic determination and enhancing charging efficiency and users' operational convenience.
