Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing power boards in supercomputing devices face issues with incomplete insertion detection, leading to false determinations and potential safety hazards due to improper positioning during hot plug operations.
Innovation Solution
The implementation of a supercomputing device with distinct first-type and second-type signal pins of varying lengths, coupled with a level detection circuit and master control circuit, allows for accurate detection of in-place information by analyzing signals from both pin types, preventing incomplete insertion.

Engineering Contradiction Analysis
1Measurement precision
If a single signal pin is used to detect in-place information, then the detection structure is simple, but the detection accuracy is insufficient leading to false determinations
Solution Approach 1:
The signal pin is divided into two distinct types: a first-type signal pin and a second-type signal pin. Each pin type has different length characteristics, allowing the system to segment the detection function into multiple independent detection points, thereby improving detection accuracy without creating a complex overall structure
Solution Approach 2:
The first-type and second-type signal pins are designed with asymmetric length differences. This asymmetry ensures that when the computing power board is incompletely inserted, the pins will make contact with the interface at different times or not at all, providing distinguishable detection signals that improve in-place detection accuracy
2Reliability
If signal pins of different lengths are used, then incomplete insertion can be detected, but the manufacturing complexity increases
Solution Approach 1:
Only specific signal pins (first-type and second-type) are given different length characteristics, while other signal pins on the computing power board maintain standard lengths. This localized differentiation achieves the safety function without requiring all components to be custom-manufactured, thus limiting the impact on overall manufacturing complexity
