Power Supply Controller with Time-Limited Threshold Exceedance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices often exceed legal power thresholds, posing safety risks, as existing power supplies lack mechanisms to temporarily exceed electrical power limits while adhering to time constraints without continuous violation.
Innovation Solution
A controller system that monitors and manages power supply settings, allowing temporary exceedance of electrical power thresholds for fixed periods, utilizing timers to ensure compliance with both power and time limits, thereby enabling higher power states within legal restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the power supply allows continuous operation above electrical power thresholds to maintain high performance, then productivity is improved, but safety hazards increase due to prolonged exceedance of legal power limits
Solution Approach 1:
The power supply controller implements periodic action by allowing the power supply to operate above electrical power thresholds only for fixed, predetermined time periods. The controller monitors the duration of threshold exceedance and automatically deactivates the power supply when the time limit is reached, converting continuous high-power operation into periodic bursts that maintain productivity while ensuring safety compliance.
2Object-affected harmful factors
If the power supply is deactivated frequently to comply with power thresholds, then safety is improved, but productivity decreases due to interrupted operation
Solution Approach 1:
The power supply controller applies dynamics by adaptively adjusting the deactivation timing based on real-time monitoring of threshold exceedance duration. Rather than using fixed periodic deactivation, the controller dynamically determines when to deactivate the power supply based on whether the predetermined time period has been exceeded, allowing maximum continuous operation while ensuring compliance.
Solution Approach 2:
The controller implements preliminary action by setting predetermined time periods for threshold exceedance before operation begins. This pre-established time limit allows the power supply to operate above thresholds without requiring continuous monitoring and intervention, enabling longer uninterrupted operation while maintaining safety compliance.
3Productivity
If the power supply operates continuously without time limits above power thresholds, then productivity is improved, but harmful effects increase due to unlimited exceedance duration
Solution Approach 1:
The power supply controller implements feedback by continuously monitoring the electrical power threshold exceedance duration and using this information to control the power supply operation. The controller receives feedback about the current power level and duration of exceedance, then automatically deactivates the power supply when the predetermined time period is reached, preventing unlimited threshold violation while maintaining maximum productive operation within safe limits.

AI summary
Example implementations relate to power supply controllers. In some examples, a controller can include instructions to: set a power threshold for a power supply coupled to a computing component when the computing component is operating in a first state, determine when the computing component is alternating from the first state to a second state, and allow the power supply to exceed the power threshold for a fixed period of time in response to the computing component alternating from the first state to the second state.
