Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If functional modules are shut down or forced into dormancy state to save energy, then power consumption is reduced, but service availability and operational reliability deteriorate

Engineering Contradiction:
Improvepower consumptionVSAvoidservice availability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent changes the voltage parameter dynamically based on load conditions. Instead of shutting down modules, the system adjusts the bus voltage to match the actual power needs of functional modules, allowing them to remain operational while consuming only the necessary power. This resolves the contradiction by maintaining service availability while reducing power consumption through parameter optimization.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If dynamic energy-saving control is implemented through CPU, then power consumption is reduced, but control complexity and response time increase

Engineering Contradiction:
Improvepower consumptionVSAvoidcontrol complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent implements a self-service mechanism where the power supply module autonomously detects load conditions and adjusts voltage without CPU intervention. The system monitors power consumption automatically and regulates voltage based on detected load states, eliminating the need for complex CPU-based control logic and reducing control complexity while maintaining energy-saving effectiveness.

Inventive Principle:
Principle #25Self-service

3Reliability

If bus voltage is maintained at high level, then service availability and operational reliability are improved, but power consumption increases

Engineering Contradiction:
Improveoperational reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the bus voltage adjustable rather than fixed. The system dynamically adapts voltage levels according to real-time load conditions, transitioning between different voltage states to match operational requirements. This allows the system to maintain high voltage only when necessary for reliability while reducing voltage during low-load periods to save energy.

Inventive Principle:
Principle #15Dynamics

4Reliability

If functional modules remain active without shutdown, then service availability is maintained, but power consumption increases

Engineering Contradiction:
Improveservice availabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent resolves this contradiction by changing the voltage parameter to match actual operational needs. Functional modules remain active to maintain service availability, but the bus voltage supplying them is dynamically adjusted to the minimum necessary level based on detected load conditions, thereby reducing power consumption without compromising operational reliability.

Inventive Principle:
Principle #35Parameter changes
