Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sub-end circuits generate standby power after system connection to AC power, then the system can operate with standby power available, but the standby power cannot be remotely controlled or changed, requiring on-site maintenance personnel for initialization

Engineering Contradiction:

Improvestandby power availabilityVSAvoidremote control capability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a remote control device as an intermediary between the user and the sub-end circuits. This remote control device communicates with the sub-end circuits through the existing baseboard management controller (BMC) interface, enabling remote initialization and control of standby power without requiring physical on-site access. The intermediary translates remote commands into the appropriate control signals that the sub-end circuits can process.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The sub-end circuits are equipped with self-service capabilities through the integration of control logic that can receive and process remote control signals. The circuits can autonomously initialize and control their own standby power generation based on remote commands, eliminating the need for external on-site maintenance personnel. The system performs maintenance tasks automatically when receiving proper control signals.

Inventive Principle:

Principle #25Self-service

2Reliability

If on-site maintenance personnel are required for initializing sub-end standby power, then proper initialization can be ensured, but maintenance difficulty and cost increase

Engineering Contradiction:

Improveinitialization accuracyVSAvoidmaintenance difficulty

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The baseboard management controller (BMC) serves as an intermediary that bridges the remote control device and the sub-end circuits. The BMC receives control signals from the remote device and translates them into the specific initialization commands required by the sub-end circuits. This intermediary ensures accurate initialization while enabling remote operation, reducing both maintenance difficulty and cost.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical requirement of physical on-site access with an electronic/communication-based control system. Instead of requiring maintenance personnel to physically access and manually initialize the sub-end circuits, the system uses electronic control signals transmitted through the BMC interface. This substitution eliminates the need for on-site presence while maintaining initialization accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple sub-end circuits are controlled individually, then each circuit can be managed independently, but the complexity of remote maintenance increases

Engineering Contradiction:

Improveindependent circuit controlVSAvoidmaintenance complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the control of multiple sub-end circuits into a unified remote control interface. The remote control device can issue commands that are distributed to multiple sub-end circuits simultaneously or individually as needed. This consolidation reduces maintenance complexity by providing a single point of control while preserving the ability to manage each circuit independently when required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The remote control device is designed with universal functionality to handle multiple types of sub-end circuits through a single interface. The baseboard management controller provides multi-functional capabilities, allowing the same control mechanism to manage different circuits with potentially different initialization requirements. This universality simplifies the maintenance process while maintaining adaptability to various circuit configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A power generating apparatus includes a power supply, a first sub-end circuit, a second sub-end circuit and an integrated signal generator. The first and second sub-end circuits respectively generate first and second sub-end standby power. The first sub-end circuit receives a first integrated control signal. The second sub-end circuit receives a second integrated control signal. The first sub-end circuit cuts off the first sub-end standby power according to the first integrated control signal and turns on the first sub-end standby power again after a first delay time. The second sub-end circuit cuts off the second sub-end standby power according to the second integrated control signal, and turns on the second sub-end standby power again after a second delay time. The integrated signal generator generates the first and second integrated control signals.
