Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power supply devices continuously provide regulated power signal when plugged into power outlet, then power regulation function is maintained, but power consumption increases and energy is wasted
Solution Approach 1:
The power supply device dynamically switches between different operating states (enabled/disabled) based on real-time detection of electronic device coupling. The control circuitry adjusts the power regulation circuitry's operational state from active to inactive, making the system adaptive rather than static, thereby eliminating continuous power consumption when not needed.
Solution Approach 2:
The system implements feedback through control circuitry that continuously monitors whether an electronic device is coupled to the power supply. Based on this feedback signal, the control circuitry automatically enables or disables the power regulation circuitry, creating a closed-loop control system that optimizes power consumption while maintaining reliability when needed.
2Productivity
If power supply device includes comprehensive control circuitry for monitoring and determining coupling status, then power management efficiency improves, but device complexity increases
Solution Approach 1:
The control circuitry is designed to perform multiple functions: detecting electronic device coupling, determining coupling status, controlling power regulation circuitry enable/disable states, and managing power storage device charging. By consolidating these functions into a single multi-functional control unit, the patent reduces overall system complexity while maintaining high power management efficiency.
Solution Approach 2:
The patent combines the control logic, sensing capabilities, and power management functions into an integrated control circuitry module. This merging of previously separate functions into a unified control system simplifies the overall device architecture while achieving comprehensive power management efficiency.
3Use of energy by moving object
If power supply device includes both low-power and high-power regulating circuitry portions that can be independently activated, then power consumption is optimized, but device complexity increases
Solution Approach 1:
The power regulation circuitry is segmented into distinct low-power and high-power portions that can operate independently. The control circuitry selectively activates only the necessary portion based on the power requirements of the coupled electronic device, enabling optimized power consumption while maintaining the capability to handle different power loads through modular segmentation.
4Measurement precision
If power supply device uses sensor in connector for determining coupling, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The connector structure itself provides the detection function through integrated sensors that automatically detect the presence and coupling status of the electronic device. The sensor leverages the existing connector infrastructure, allowing the connector to serve both its primary electrical connection function and the secondary function of coupling detection, thereby improving detection accuracy without proportionally increasing complexity.
