Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data erasure processes are used to protect sensitive data, then data protection is improved, but the protection is inadequate against theft and reverse engineering
Solution Approach 1:
The patent applies preliminary anti-action by pre-installing a reactive layer that automatically destroys the functional layer (and stored data) when activation conditions are met, preventing data theft and reverse engineering before they can occur. This proactive destruction mechanism addresses the inadequacy of conventional erasure methods by ensuring permanent data elimination rather than merely hiding it.
2Reliability
If a reactive layer is added to destroy the functional layer, then data protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the destruction function directly into the storage device structure by integrating a reactive layer with the functional layer. This combination allows the destruction capability to be embedded within the existing device architecture rather than adding a separate external system, thereby limiting the increase in device complexity while maintaining enhanced data protection.
Solution Approach 2:
The reactive layer is designed to automatically activate and destroy the functional layer when specific conditions are met, without requiring external intervention or complex control systems. This self-service mechanism simplifies the overall device architecture by eliminating the need for additional activation systems while still providing robust data protection.
3Ease of manufacture
If conventional data erasure methods are used, then manufacturing simplicity is maintained, but protection against theft and reverse engineering is insufficient
Solution Approach 1:
The patent employs composite materials by creating a reactive layer composed of alternating fuel and oxidizer sub-layers. This composite structure enables the layer to generate high temperatures upon activation, providing effective destruction capability while maintaining compatibility with existing manufacturing processes. The composite material approach allows for straightforward fabrication using standard deposition techniques.
