Peripheral Device Insertion Detection Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting peripheral device insertion into PCI slots are time-consuming and prone to errors, leading to potential device damage and increased maintenance costs, as they require post-booting detection and do not ensure complete insertion before booting.
Innovation Solution
A system comprising a logic component connected to test pins of the peripheral interface slot, which outputs a judgment value based on pin potentials to determine complete insertion, interrupting the booting process and sending an alarm if the device is not fully inserted, using a NOR gate to differentiate insertion states and a switch for selective detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If post-booting detection is used to check peripheral device insertion, then the system can detect whether the device is inserted, but the detection process is time-consuming and may cause device damage
Solution Approach 1:
The patent implements preliminary detection before the PC boots by using a detecting unit that checks the insertion state of the peripheral device during the power-on phase, before the operating system loads. This early detection prevents time-consuming post-boot testing and avoids potential device damage by identifying insertion issues before full system operation begins.
Solution Approach 2:
The patent replaces manual insertion verification with an automated electrical detection system. The detecting unit uses electrical signals to automatically determine whether the peripheral device is properly inserted, eliminating the need for manual checking and reducing both time and potential for human error.
2Ease of operation
If manual insertion verification is performed, then the user can check the device placement, but the process increases maintenance costs and is inconvenient
Solution Approach 1:
The system performs self-verification of peripheral device insertion through the detecting unit, which automatically checks whether the device is properly connected. This eliminates the need for user manual verification and reduces maintenance costs by preventing damage from improper insertion through automated monitoring.
Solution Approach 2:
The detecting unit provides immediate feedback to the user about the insertion state of the peripheral device. When the device is not properly inserted, the system can display an alert or prevent booting, giving clear feedback that guides the user to correct the insertion issue without requiring technical knowledge or increasing maintenance complexity.

AI summary
A system for detecting a peripheral device is used to detect whether the peripheral device is completely inserted into a peripheral interface slot of a mother board before booting. When the peripheral device is inserted into the peripheral interface slot, the system judges whether the peripheral device is completely inserted into the peripheral interface slot according to a potential of fins of the peripheral interface slot. If the system detects that the peripheral device has not been completely inserted into the peripheral interface slot before booting, a booting procedure of the mother board is interrupted and an alarm signal is output.
