Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external power is supplied to components, then the components can operate reliably, but power is continuously supplied regardless of operation status leading to unnecessary power consumption
Solution Approach 1:
The power supply system transitions from a static continuous power delivery mode to a dynamic mode where power is supplied only when components actually need to operate. The power generating circuit responds to operation status signals and adjusts power delivery accordingly, supplying power during operation and cutting off during idle states, thus resolving the contradiction between reliable operation and power consumption.
Solution Approach 2:
The system implements feedback control where the operation status of components is detected and fed back to the power generating circuit. Based on this feedback information, the power circuit adjusts its power output - maintaining power supply when operation is detected and stopping power supply when operation ceases, thereby eliminating unnecessary power consumption while ensuring reliable operation when needed.
2Adaptability or versatility
If separate external power supply is provided to components, then components can function independently, but it leads to difficulty in on-chip integration and requires separate pins for power reception limiting miniaturization
Solution Approach 1:
The patent merges the power supply function with the control signal function. The power generating circuit integrates multiple transistors and control logic into a single unified circuit block that can serve multiple components. Instead of separate external power supplies for each component, the integrated circuit generates and distributes power internally based on control signals, reducing the number of external pins needed and simplifying on-chip integration while maintaining component independence through controlled power delivery.
Solution Approach 2:
The power generating circuit is designed as a universal power source that can serve multiple different components within the electronic device. Rather than requiring dedicated external power supplies for each component, this single multi-functional power circuit can selectively power different components based on their operation status, thereby reducing integration complexity and enabling miniaturization while preserving component versatility.
3Use of energy by moving object
If multiple transistors are used in the power generating circuit, then power can be generated only when control signals are applied reducing power consumption, but the circuit complexity increases
Solution Approach 1:
The power generating circuit is segmented into multiple transistor stages, each performing a specific function in the power generation process. By dividing the circuit into discrete functional segments (different transistor groups handling different aspects of power control), the design achieves efficient power generation through control signals while organizing complexity into manageable, modular sections that can be systematically integrated.
