Solution Overview

Problem

Existing methods for destroying solid state drives (SSDs) often fail to ensure complete and irreversible data destruction, leading to potential data recovery and confidentiality breaches, especially when improper disposal occurs, which can result in significant financial and reputational losses.

Innovation Solution

A high-speed SSD destroyer apparatus featuring counter-rotating rollers with cylindrical arrays of hardened steel teeth that create a distinctive waffle pattern on the SSD shell, rendering the data inaccessible while maintaining the SSD's physical integrity, capable of processing SSDs at a rate of 1 every 5 seconds and handling drives of 1.5 to 2.5 inches without removing casings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If electronic erasing is performed to destroy data on SSD, then data confidentiality is improved, but the physical drive is completely destroyed leaving no traceable body

Engineering Contradiction:
Improvedata confidentialityVSAvoidtraceability of destroyed drive
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The destruction process is segmented into two distinct stages: first, electronic erasing to destroy data confidentiality, and second, physical marking to create traceability. This segmentation allows both requirements to be met independently without compromising either data security or drive identification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electronic erasing action is performed preliminarily before physical destruction. By erasing data first and then applying physical marks, the system ensures data confidentiality is established before the drive becomes unrecognizable, solving the contradiction between complete data destruction and maintaining traceability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If SSD is cut into fragments for complete destruction, then data recovery is prevented, but the physical shape and traceability are lost

Engineering Contradiction:
Improvedata destruction completenessVSAvoidphysical integrity of SSD
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

Instead of uniformly fragmenting the entire SSD, the invention applies localized physical marks (cracks, dents, or etchings) at specific locations on the drive casing. This local quality approach ensures data destruction reliability through targeted damage while preserving the overall physical shape and traceability of the drive.

Inventive Principle:
Principle #3Local quality

3Productivity

If high-speed destruction is implemented to increase productivity, then processing rate is improved, but destruction thoroughness may be compromised

Engineering Contradiction:
ImproveSSD destruction rateVSAvoiddestruction completeness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The invention replaces complex mechanical fragmentation systems with a simplified electronic erasing mechanism followed by rapid physical marking. This substitution maintains high productivity (720 SSDs per hour) while ensuring destruction thoroughness through the combination of electronic data erasure and distinctive physical patterns that prevent data recovery.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of manufacture

If physical marks are applied to maintain traceability, then drive identification is improved, but data destruction effectiveness is reduced

Engineering Contradiction:
Improvetraceability of destroyed driveVSAvoiddata destruction effectiveness
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The electronic erasing action is performed preliminarily before physical marking. By erasing data first and then applying physical marks, the system ensures data confidentiality is established before the drive becomes unrecognizable, solving the contradiction between complete data destruction and maintaining traceability.

Inventive Principle:
Principle #10Preliminary action

AI summary

Disclosed is an apparatus for destroying the operational aspects and electronic media of a Solid State Drive (SSD) yet maintaining the physical shape of the SSD for identification. The apparatus includes a crusher box having counter-rotating rollers that are intermeshed to provide a high speed feed of an SSD wherein teeth formed on the rollers render the electron media non-accessible and impart a distinctive waffle like appearance for ease of identifying destroyed SSD's. A VFD-PID controller is used to vary the speed of an electric motor 50 with the PID having a feedback signal that allows for various target values to be set.
