Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each device is tested to obtain power usage characteristics, then measurement precision is improved, but productivity deteriorates and manufacturing cost increases
Solution Approach 1:
The patent uses simulation to create a virtual model of the data processing device that replicates its power consumption behavior. The simulation model is trained using a subset of actual device measurements, then used to predict power usage characteristics for remaining devices without physical testing, thereby maintaining measurement precision while dramatically improving productivity
Solution Approach 2:
The patent performs preliminary characterization on a subset of devices to build a simulation model before mass production. This preliminary action creates a predictive tool that can rapidly estimate power usage for all subsequent devices, eliminating the need for time-consuming individual testing of each device while maintaining accurate power usage characterization
2Measurement precision
If each device is tested to obtain power usage characteristics, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The simulation model serves as a virtual copy of the physical device's power consumption behavior. Once trained on a small subset of actual measurements, the simulation can predict power usage for all devices at minimal cost, eliminating the expensive and time-consuming process of individual device testing while maintaining accurate power usage characterization
Solution Approach 2:
The patent changes the approach from direct physical measurement to simulated prediction based on operational parameters. By analyzing input data characteristics and processing conditions in the simulation, the system can estimate power usage without requiring expensive test equipment and measurement infrastructure for each device
3Use of energy by moving object
If convergence-based processing is used, then power consumption is reduced, but measurement precision deteriorates due to variable iteration counts
Solution Approach 1:
The simulation applies a fixed number of iterations that may be more than the minimum required for convergence in some cases, but ensures consistent power usage measurement. This partial excessive action guarantees that all devices are measured under identical conditions, providing consistent and comparable power usage data while still achieving adequate processing convergence
