Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power management systems are overdesigned to handle maximum peak power demands, then reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements dynamic power credit allocation where the power management system adjusts power distribution in real-time based on actual device conditions and processing unit requirements. Instead of static overdesign, the system dynamically scales power allocation to match actual demands, resolving the contradiction between reliability and complexity by making the system adaptive rather than permanently over-provisioned
Solution Approach 2:
The system changes the parameter of power allocation from fixed maximum values to variable power credits that are distributed based on performance characteristics and actual needs. This parameter transformation allows the system to maintain reliability through flexible adjustment while reducing complexity by eliminating the need for permanent overdesign capacity
2Use of energy by moving object
If power management systems are overdesigned to handle worst-case scenarios, then power availability is improved, but manufacturing costs increase
Solution Approach 1:
The patent transforms power allocation from fixed worst-case provisioning to dynamic parameter adjustment based on actual performance characteristics. Power credits are allocated according to real-time conditions and processing unit requirements, allowing the system to maintain power availability when needed while reducing manufacturing costs by eliminating permanent overdesign
Solution Approach 2:
The system implements dynamic power availability management where power credits are adjusted based on actual device conditions and processing unit performance characteristics. This dynamic approach ensures power availability is maintained during peak demands while reducing the need for permanent overdesign capacity that increases manufacturing costs
3Productivity
If power credits are distributed based on performance characteristics, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service power management mechanism where processing units report their own performance characteristics and power requirements to the power management system. The system automatically distributes power credits based on these reported characteristics without requiring complex external control, thereby improving productivity while minimizing the added complexity through autonomous operation
