VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple output nodes are used to generate different potentials, then the versatility of the circuit is improved, but the complexity of controlling potential stabilization across different loads increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic control by having the control circuit continuously monitor the potential at each output node and adjust the switching state of connected circuits in real-time. This dynamic adjustment allows the system to adapt to varying load conditions at different output nodes, maintaining potential stabilization without requiring complex predetermined control schemes for each possible load configuration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control circuit employs feedback mechanisms by detecting the actual potential at each output node and using this information to control the switching operations. The feedback loop enables the system to automatically adjust its behavior based on the current state of each output node, simplifying the control architecture while ensuring proper potential stabilization across multiple outputs with different load conditions.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The control circuit performs preliminary actions by proactively adjusting the switching state of connected circuits based on detected potential conditions before significant deviations occur. When a potential at an output node approaches its target value, the control circuit anticipates the need for switching adjustments and prepares accordingly, reducing the overall stabilization time while maintaining precise potential generation timing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control circuit implements periodic monitoring and adjustment of output potentials, continuously detecting potential values and making rhythmic switching adjustments. This periodic action ensures that potentials are generated with precise timing while the regular monitoring cycle prevents prolonged stabilization periods by catching potential deviations early and correcting them systematically.

Inventive Principle:

Principle #19Periodic action

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The control circuit applies preliminary anti-action by detecting potential conditions at output nodes and preemptively controlling the switching state to prevent reverse current flow before it can occur. When the control circuit detects that a potential is approaching a level that might cause reverse current, it adjusts the switching state in advance to block the harmful reverse flow, thus protecting the circuit while maintaining adaptability to different load conditions.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The control circuit uses feedback from potential detection at each output node to dynamically control switching operations that prevent reverse current. By continuously monitoring potential levels and using this feedback to adjust switching states, the system adapts to different load conditions while the feedback loop automatically prevents reverse current flow by closing switches at appropriate moments to block reverse current paths.

Inventive Principle:

Principle #23Feedback
