Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tens of power sockets are divided into a plurality of charging groups with electrically-controlled switches, then the current value within each charging group can be controlled to be smaller than the upper limited current value, but the electrically-controlled switch will be frequently switched and its lifetime will be decreased
Solution Approach 1:
The patent implements dynamic charging zone management where zones are activated or deactivated based on real-time current measurements. The control unit dynamically adjusts which charging zones are operational to maintain current below the upper limited threshold, replacing static switch group configurations with adaptive zone control that responds to actual power demands of connected devices.
Solution Approach 2:
The patent replaces electrically-controlled switches with a control unit that manages charging zones through software-based current measurement and zone activation/deactivation logic. This substitution eliminates the mechanical wear associated with frequent switch operations while achieving the same current control objective through digital control and selective zone enabling.
2Productivity
If the charging control system simultaneously charges tens of digital devices, then all devices can be charged, but the required current value may exceed the upper limited level of the power distribution system and cause tripping of the circuit breaker
Solution Approach 1:
The patent divides the charging system into multiple independent charging zones, each capable of being individually activated or deactivated. This segmentation allows the control unit to distribute the total current load across available zones, enabling simultaneous charging of multiple devices while maintaining the current within each active zone below the upper limited threshold to prevent circuit breaker tripping.
Solution Approach 2:
The control unit dynamically measures the current value for each charging zone and selectively activates or deactivates zones based on real-time conditions. This dynamic adjustment enables the system to maximize charging capacity while ensuring the total current drawn from the power distribution system remains within safe limits, preventing circuit breaker tripping.
3Productivity
If various amounts of current values are provided according to various amounts of remained power level of digital devices, then charging efficiency is improved, but the complexity of power management increases
Solution Approach 1:
The patent implements a system where the control unit automatically measures current values for each charging zone and autonomously determines which zones to activate or deactivate based on predefined current thresholds. This self-service approach eliminates the need for manual power management intervention, allowing the system to efficiently allocate power to devices with different charging needs while keeping the management process automated and relatively simple.
