Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional software-based data erasure methods are used, then data can be erased from non-volatile memories, but the process is tedious and requires partial device functionality
Solution Approach 1:
The patent replaces the software-based mechanical access method (requiring booting and software commands) with a direct physical irradiation method using X-ray sources that chemically/electronically erase data through radiation-induced electron ejection from floating gates, eliminating the need for device booting and software operation
Solution Approach 2:
The patent introduces an intermediary irradiation chamber and X-ray source system that acts as a mediator between the erasure command and the memory, allowing data erasure without direct access to the device's software or hardware systems
2Reliability
If devices are destroyed by grinding and melting to erase data, then data erasure is achieved, but significant economic and ecological waste is generated
Solution Approach 1:
The patent changes the erasure mechanism from physical destruction (grinding, melting) to a controlled physical process of electron ejection through X-ray irradiation, which erases data by removing electrons from floating gates while preserving the physical structure and functionality of the device
Solution Approach 2:
The patent converts the potentially harmful effect of high-energy radiation (which could destroy devices) into a beneficial controlled process that selectively erases data through electron ejection from floating gates while preserving other device components
3Reliability
If ionizing radiation is used to erase memory data, then complete data erasure is achieved, but the solution is limited to manufacturing phase and cannot be applied to functional devices
Solution Approach 1:
The patent makes the irradiation system dynamic and adaptable by controlling parameters such as irradiation dose, exposure time, and source position to suit different device types and memory configurations, enabling the same system to handle various functional devices rather than being fixed for manufacturing only
Solution Approach 2:
The patent adjusts irradiation parameters (dose, time, geometry) to optimize the balance between complete data erasure and device preservation, making the process adaptable to different device states and requirements
4Productivity
If automated irradiation is implemented, then data erasure speed and consistency are improved, but device complexity increases
Solution Approach 1:
The patent designs a universal irradiation chamber system that can handle multiple device types and configurations through programmable control, eliminating the need for separate dedicated systems for each device type while maintaining high processing speed and consistency
