Resistive Short Detection Circuitry for Information Handling Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in detecting resistive shorts, which can lead to hardware damage and potential fires due to the inability to accurately monitor power distribution and consumption, resulting in undetected shorts that persist over time.
Innovation Solution
Incorporating resistive short detection circuitry that measures the power provided by a power supply system and the power consumed by components, using comparators and digital interface multiplexors to identify any excess power, triggering a shutdown when a resistive short is detected to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power monitoring methods are used, then the system can operate continuously, but resistive shorts cannot be detected leading to hardware damage and potential fires
Solution Approach 1:
The patent implements preliminary detection by continuously monitoring power distribution before a resistive short can cause damage. The detection circuitry compares expected power consumption with actual power distribution in real-time, enabling early identification of abnormal conditions before they escalate to hardware damage or fire hazards.
Solution Approach 2:
The patent introduces an intermediary detection circuit that acts as a mediator between the power supply system and the load. This circuit includes comparison logic that mediates between expected power consumption values and actual power distribution measurements, generating alerts when discrepancies indicate a resistive short condition.
2Object-affected harmful factors
If power monitoring is implemented to detect shorts, then system safety improves, but the complexity of the detection system increases
Solution Approach 1:
The patent segments the power monitoring function into distinct modular components: power distribution measurement units, expected consumption calculation units, comparison logic units, and alert generation units. This segmentation allows each component to perform a specific function independently, making the overall system more manageable and easier to implement despite the increased complexity.
Solution Approach 2:
The detection circuitry is designed with universal applicability across different system configurations. The monitoring mechanism can detect resistive shorts in various locations (power distribution paths, component connections, grounding systems) and can be adapted to different power levels and system architectures, reducing the need for multiple specialized detection systems.

AI summary
An information handling system includes resistive short detection circuitry that measures a first amount of power provided by a power supply system, and measures a second amount of power drawn by components. The resistive short detection circuitry compares the first amount of power with the second amount of power. In response to first amount of power being greater than the second amount of power, the resistive short detection circuitry determines that a short exists within the information handling system.
