Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operation frequency and voltage are increased to enhance performance, then the graphics processing performance is improved, but the voltage becomes unstable and the system crashes
Solution Approach 1:
The patent implements dynamic frequency switching by providing multiple computer control chips with different operation frequencies and automatically switching between them based on real-time voltage stability detection. The operation control device adjusts the operating frequency from a first frequency to a second frequency when voltage instability is detected, and vice versa when stability is achieved, creating a dynamic adaptation system that resolves the contradiction between performance and stability
Solution Approach 2:
The patent employs a feedback mechanism where the inspection module continuously detects voltage stability and provides this information to the operation control device. Based on this feedback, the system automatically adjusts the operating frequency of the computer control chip - increasing frequency when voltage is stable and decreasing frequency when voltage becomes unstable - thereby maintaining both performance and stability through closed-loop control
2Productivity
If a single computer control chip with high frequency is used to provide sufficient performance, then the performance is improved, but the voltage instability causes system crashes
Solution Approach 1:
The patent segments the computer control chip functionality into multiple chips with different operation frequencies (first computer control chip with lower frequency and second computer control chip with higher frequency). Instead of relying on a single high-frequency chip that causes instability, the system divides the workload and dynamically selects which chip to operate based on voltage stability conditions, thus achieving both performance and reliability
Solution Approach 2:
The patent changes the operating parameter (frequency) of the computer control chip based on detected voltage stability. When voltage is stable, the system operates at higher frequency for maximum performance; when voltage becomes unstable, the system switches to lower frequency to maintain stability. This parameter adaptation resolves the contradiction by making frequency a variable rather than a fixed value
3Reliability
If the frequency is cyclically adjusted to maintain stability, then the voltage stability is improved, but the performance becomes insufficient and the system cannot achieve desired gaming performance
Solution Approach 1:
The patent implements a dynamic frequency switching mechanism that adapts to real-time voltage conditions. Rather than cyclically adjusting a single frequency or being forced to operate at low frequency for stability, the system dynamically switches between multiple chips with different frequencies based on actual voltage stability detection, allowing maximum performance when conditions permit and maintaining stability when conditions deteriorate
Solution Approach 2:
The system performs self-adjustment through automatic frequency switching based on voltage stability detection. The operation control device autonomously determines when to switch between first and second computer control chips based on inspection module feedback, eliminating the need for manual intervention or cyclic adjustment algorithms, and achieving both stability and performance through self-service adaptation

AI summary
A simulation switching device of computer control chips is disclosed, including an addin card body, a plurality of computer control chips having different operation frequencies arranged on the addin card body, a graphics processing device in information connection with each of the computer control chips, an operation control device in information connection with each of the computer control chips and the graphics processing device, and an inspection module in information connection with the operation control device. To use, the operation control device detects a voltage of the graphics processing device. If the voltage is in an unstable condition, then the inspection module performs simulation to inspect a condition that will be generated by driving another one of the computer control chips that has a relatively high operation frequency, and automatic switching is made to the computer control chip having the relatively high operation frequency to make the voltage stable.
