Flash Memory Chip Drilling for Automated Mobile Data Destruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data destruction in mobile communication devices are time-consuming, laborious, and inadequate in ensuring complete removal of user data, particularly from flash memory chips, posing a risk of unauthorized access.
Innovation Solution
An automated data destruction system comprising a platform, securement mechanism, positioning mechanism, drill, vision recognition system, and controlling system, which accurately identifies and secures the device, locates the flash memory chip, and penetrates it to destroy data efficiently while preserving other components, with an optional fire suppression system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data destruction methods (shredding entire device or motherboard) are used, then data security is improved, but device complexity increases and other components cannot be reused
Solution Approach 1:
The system segments the destruction process to target only the flash memory chip containing user data, rather than destroying the entire device or motherboard. The drill precisely locates and destroys only the flash memory chip, separating the data destruction function from the physical device structure, thereby ensuring data security while preserving other components for reuse.
Solution Approach 2:
The system extracts the flash memory chip location information from the device schematic stored in the controller, and uses this extracted information to guide the drill to the precise location. This extraction of critical information enables targeted destruction of only the data-containing component without affecting other parts.
2Productivity
If automated positioning and drilling systems are implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: storing device schematics, identifying flash memory chip locations, controlling the drill positioning, and managing the destruction process. This multi-functionality consolidates what could be separate complex subsystems into a single coordinating unit, improving productivity while managing system complexity.
Solution Approach 2:
The system replaces manual positioning and identification methods with an automated optical scanning and controller-based positioning system. The drill position is controlled through electronic coordination rather than manual mechanical adjustment, significantly improving productivity and precision.
3Manufacturing precision
If precise positioning mechanisms are used to locate flash memory chip, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The system uses a copied representation of the device structure (schematic stored in controller) to guide the physical destruction process. The controller contains a digital model of the device layout with flash memory chip location marked, which is then used to position the drill without requiring complex physical measurement and positioning mechanisms.

AI summary
The present invention provides an automated data destruction system to remove data effectively and reliably from a mobile communication device. The system comprises a housing, a platform, a securement mechanism, a positioning mechanism, a power drill, a vision recognition system, and a controlling system. The vision recognition system and the processor identify the mobile communication device, and the controlling system controls the securement mechanism, the positioning mechanism, and the power drill to a corresponding location based on the identified mobile communication device and activates the power drill to penetrate the mobile communication device at an exact depth to restrict the damage to the flash memory chip.
