Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power supplies and capacitive discharge systems are used to deliberately destroy integrated circuits, then destruction capability is achieved, but the device becomes bulky and slow
Solution Approach 1:
The patent changes the electrical parameters by using high voltage (thousands to tens of thousands of volts) and large capacitance (five thousand μF or more) to deliver sufficient energy for destruction while maintaining a compact form factor. This resolves the contradiction by optimizing the voltage and capacitance parameters to achieve both destruction capability and reduced device size.
Solution Approach 2:
The system uses rapid charging and discharging cycles of the capacitor to deliver destructive energy impulses. The capacitor charges quickly from the power supply and then discharges rapidly through the target circuit, creating periodic high-energy pulses that ensure destruction while keeping the device compact and fast-operating.
2Reliability
If conventional power supplies and capacitive discharge systems are used to deliberately destroy integrated circuits, then destruction capability is achieved, but the operation speed becomes slow
Solution Approach 1:
The system employs rapid periodic charging and discharging of the capacitor, creating fast energy impulses. The capacitor charges quickly and discharges in a brief high-current pulse through the target circuit, achieving both reliable destruction and fast operation speed by optimizing the temporal characteristics of energy delivery.
Solution Approach 2:
By using high voltage and large capacitance parameters, the system delivers sufficient destructive energy in a very short time interval. The high voltage enables rapid energy transfer, and the large capacitance stores enough energy to ensure destruction even with the shortened discharge time, thus resolving the speed-reliability contradiction.
3Reliability
If static protection structures are added to integrated circuits, then susceptibility to static discharge is reduced, but difficulty of deliberate destruction increases
Solution Approach 1:
The system overcomes static protection structures by using extremely high voltage (thousands to tens of thousands of volts) and large capacitance (five thousand μF or more). These exaggerated electrical parameters generate energy levels that exceed the protection capabilities of standard static protection structures, thereby maintaining destruction capability despite the presence of protection circuits.
Solution Approach 2:
The patent converts the presence of static protection structures into an opportunity to demonstrate superior destruction capability. By designing a system with such high voltage and capacitance that it can penetrate through protection structures, the invention turns the protective measures into a benchmark that validates the effectiveness of the destruction system.
