Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the output circuits remain continuously operational to ensure immediate power availability, then the power supply readiness is improved, but the power consumption increases and service life decreases

Engineering Contradiction:
Improvepower supply readinessVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic control of output circuits by the main control circuit, which monitors load conditions in real-time and adjusts circuit states accordingly. When no load is detected for a preset time period, the control circuit automatically turns off the output circuits to save energy. When load is detected, the circuits are immediately activated, achieving both energy savings and quick power availability.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If the output circuits are turned off during no-load conditions to reduce power consumption, then the power efficiency is improved, but the response time to provide power may increase

Engineering Contradiction:
Improvepower efficiencyVSAvoidresponse time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The main control circuit continuously monitors load conditions in advance and maintains system readiness. When a load is detected on the output circuits, the control circuit proactively activates the circuits before complete power delivery is needed, ensuring minimal response time. The preset time period for turning off circuits is optimized to balance energy savings with rapid response capability.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If continuous monitoring of load conditions is implemented to enable automatic circuit control, then the power management efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improvepower management efficiencyVSAvoidcontrol circuit complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The main control circuit performs multiple functions: it monitors load conditions on output circuits, determines when to turn circuits on or off based on preset time periods, manages power distribution, and controls indicator lights. By consolidating these functions into a single control circuit, the patent achieves efficient power management without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
