Innovation Solution

A power supply control device that includes a switching unit to turn the switch on or off and a determination unit to determine power supply control conditions based on the current waveform of the load, allowing for immediate updates by detecting changes in the load and adjusting control conditions accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If customized information is transmitted from another device to update power supply control conditions, then the power supply control conditions can be updated according to the changed load, but the updating process requires a long period of time

Engineering Contradiction:
Improvepower supply control conditions updateVSAvoidupdating time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The power supply control device automatically detects load changes by monitoring current waveforms and self-determines updated power supply control conditions without requiring external customized information transmission. The determination unit analyzes the current waveform characteristics and autonomously updates the control conditions, enabling the system to serve itself and eliminate dependency on external devices for information transmission.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where the current waveform information from the load is continuously monitored and fed back to the determination unit. Based on this feedback, the power supply control conditions are dynamically adjusted and updated in real-time, creating a closed-loop control system that automatically adapts to load changes without external intervention.

Inventive Principle:
Principle #23Feedback

2Productivity

If customized information transmission is used to update power supply control conditions, then the control conditions can be updated, but the transmission process requires a long period of time

Engineering Contradiction:

AI summary

A power supply control device controls power supply to a load through a power supply switch. A driving circuit switches on or off the power supply switch. When the driving circuit switches the power supply switch from off to on, a waveform value regarding the current waveform of a current that flows through the load is output by a waveform value detection unit to a microcomputer. The microcomputer determines power supply control conditions regarding control of power supply to the load based on the waveform value that is input from the waveform detection unit.
