Boot Control Circuit With Detection Pin for Safe Power-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems, inexperienced operators often turn on the power before ensuring all components are properly assembled, risking damage to the central processing unit due to incorrectly arranged connection pins, which can lead to abnormal currents and potential motherboard burnout.
Innovation Solution
A boot control circuit is introduced, featuring a detection pin and switch configuration that prevents the system power module from providing power unless the detection pin is correctly connected to the motherboard, ensuring the system remains in a shutdown state until all components are correctly positioned, thereby preventing abnormal current flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the power is turned on before checking component assembly, then the computer system can be powered up for testing, but the motherboard may be damaged by abnormal currents due to incorrect connection pin arrangement
Solution Approach 1:
The patent implements a preliminary connection verification mechanism using a detection pin that must be properly connected to a switch on the motherboard before the system can be powered on. This preliminary action ensures that all components are correctly assembled before power is applied, preventing abnormal currents from damaging the motherboard while still allowing quick booting once the connection is verified.
2Reliability
If a detection pin and switch connection mechanism is added, then the motherboard is protected from abnormal currents, but the device complexity increases
Solution Approach 1:
The patent extracts the safety verification function into a separate, dedicated detection pin and switch mechanism. Rather than complicating the existing power control circuitry, the invention isolates the connection verification function into distinct components that simply need to be connected together, providing motherboard protection with minimal added complexity.
