Engineering Contradictions & Design Principles
Engineering 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
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.
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
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.
3Reliability
If bus voltage is maintained at high level, then service availability and operational reliability are improved, but power consumption increases
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.
4Reliability
If functional modules remain active without shutdown, then service availability is maintained, but power consumption increases
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.
