Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If each memory device operates independently with its own power generation unit, then each channel can be accessed independently, but direct current consumption increases and active timing becomes irregular

Engineering Contradiction:

Improveindependent channel accessVSAvoiddirect current consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges power generation resources by introducing a common power generation unit that serves multiple memory devices across different channels. The common control unit coordinates power generation across channels, allowing independent channel access while sharing power generation resources to reduce overall direct current consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic control of power generation units based on actual channel operation states. The common control unit adjusts power generation timing and intensity according to which channels are active, enabling irregular active timing to be managed efficiently and reducing power consumption during periods when not all channels are in use.

Inventive Principle:

Principle #15Dynamics

2Use of energy by moving object

If power generation units are shared across channels, then direct current consumption decreases, but it becomes difficult to anticipate direct current voltage levels due to irregular active timing

Engineering Contradiction:

Improvedirect current consumptionVSAvoiddirect current voltage level predictability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The common control unit implements feedback mechanisms by monitoring the operation states of multiple channels and adjusting power generation accordingly. This feedback loop allows the system to anticipate and maintain stable direct current voltage levels despite irregular active timing across different channels, as the control unit responds to actual channel states in real-time.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes operational parameters of power generation units based on detected channel states. The common control unit modifies power generation timing, intensity, and duration parameters according to which channels are active, ensuring that direct current voltage levels remain predictable and controllable even with irregular channel activity patterns.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If memory devices operate independently, then channel independence is maintained, but standby voltage ripple increases and standby currents increase

Engineering Contradiction:

Improvechannel independenceVSAvoidstandby voltage ripple and current

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent merges standby power management across channels by using a common power generation unit and common control unit. During standby operations, the common control unit coordinates power generation to serve multiple channels simultaneously, reducing individual channel standby requirements and minimizing voltage ripple and standby currents while preserving channel independence.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common power generation unit provides equipotential power supply to multiple channels during standby operations. By generating power at a stable, consistent voltage level that serves all channels uniformly, the system reduces voltage ripple and minimizes standby currents while maintaining the ability to independently access any channel when needed.

Inventive Principle:

Principle #12Equipotentiality
