Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems allocate power tokens based on worst-case scenarios, leading to inefficiencies due to fluctuations in leakage current caused by temperature and voltage variations, resulting in excess resource allocation and reduced overall system efficiency.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power tokens are allocated based on worst-case scenarios, then system reliability is improved, but system efficiency deteriorates due to excess resource allocation
Solution Approach 1:
The patent implements dynamic power token allocation by continuously monitoring leakage current and adjusting power distribution in real-time based on actual system conditions rather than using fixed worst-case estimates. This allows the system to adapt power allocation to actual operational requirements, reducing waste while maintaining reliability.
Solution Approach 2:
The patent introduces feedback mechanisms where leakage current measurements are used to adjust power token allocations. The system monitors actual power consumption and leakage characteristics, then uses this information to optimize future power distribution decisions, creating a closed-loop control system that improves both efficiency and reliability.
2Loss of energy
If static power tokens are allocated to compensate for leakage current, then power loss is reduced, but system flexibility deteriorates
Solution Approach 1:
The patent replaces static power token allocations with dynamic allocation strategies that adjust in real-time based on monitored leakage current. This allows the system to optimize power distribution continuously, maintaining flexibility while compensating for power losses through adaptive rather than fixed allocation methods.
Solution Approach 2:
The patent changes the allocation parameters dynamically based on measured leakage current values. Instead of using fixed allocation rules, the system adjusts power token distributions according to actual leakage conditions, enabling both energy efficiency and operational flexibility through parameter adaptation.
3Productivity
If power token allocation is optimized for actual leakage current, then system efficiency is improved, but measurement and control complexity increases
Solution Approach 1:
The patent implements self-service measurement where the system uses its own operational data (voltage, current, temperature readings) to determine leakage characteristics and adjust power allocation. This self-measuring approach eliminates the need for external complex measurement equipment while maintaining accurate leakage compensation and improved efficiency.
Solution Approach 2:
The patent makes the power management circuit perform multiple functions: it monitors voltage, current, and temperature, measures leakage current, calculates optimal power allocation, and controls power distribution. By consolidating these functions into a single multi-functional system, the patent reduces overall device complexity while achieving efficient leakage-compensated power management.

AI summary
A method includes determining a temperature and a voltage associated with a system, driving the system into an idle state responsive to determining the temperature and the voltage, measuring a leakage current of the system while in the idle state, associating the temperature and the voltage with the measured leakage current, and allocating a power token based on the temperature, the voltage, and the measured leakage current.
