Solution Overview

Problem

Information handling systems refurbished for resale often retain personal data due to lack of expertise or time for thorough data erasure, leading to incomplete formatting and re-imaging processes.

Innovation Solution

A system and method involving a detachable memory device that retrieves image restoration information, cleanses the hard disk drive, and re-images it to the original factory state, ensuring complete data erasure by using a re-imaging tool stored on a mobile non-volatile device like a USB drive, leveraging tools like PC Restore to perform a bit-by-bit format.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a retail store refurbishes an information handling system by re-imaging the hard disk drive, then the system can be resold, but personal information from the previous end user may remain on the hard disk drive

Engineering Contradiction:
Improverefurbishment speedVSAvoiddata erasure completeness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing a bit-level format operation to erase all data from the hard disk drive before re-imaging the system. This pre-erasure step ensures that no personal information remains on the drive, addressing the data security concern while maintaining an efficient refurbishment process. The erasure is performed automatically as part of the re-imaging workflow, preventing data leakage without significantly extending the refurbishment timeline.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a manufacturer performs a bit level formatting to erase all data, then data security is improved, but the process time and complexity increase

Engineering Contradiction:
Improvedata erasure completenessVSAvoidrefurbishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements self-service by integrating the bit-level format operation directly into the automated re-imaging process. The system performs the data erasure autonomously without requiring manual intervention from retail store employees, who lack the expertise or time for thorough data erasure. This automation ensures complete data erasure while maintaining efficient refurbishment turnaround, as the process is executed automatically as part of the standard re-imaging workflow.

Inventive Principle:
Principle #25Self-service

3Reliability

If retail store employees perform data erasure manually, then data security may be improved, but the process becomes too complex and time-consuming

Engineering Contradiction:
Improvedata erasure completenessVSAvoidrefurbishment process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent eliminates manual data erasure operations by implementing an automated bit-level format process that executes as part of the re-imaging workflow. This removes the need for retail store employees to perform complex manual data erasure procedures, reducing process complexity while ensuring complete data security. The system handles the entire erasure and re-imaging process automatically, making the refurbishment process simple and reliable for retail environments.

Inventive Principle:
Principle #25Self-service

AI summary

An information handling system is returned to its original manufacture state with a tool stored on a detachable memory device that retrieves image restore information from non-volatile memory of the information handling system, cleanses information stored on the non-volatile memory and then returns the image restore information to the non-volatile memory. By executing an image restore tool that applies the image restore information, the original manufacture image is re-built in the non-volatile memory after the cleansing so that any personal information stored on the non-volatile memory by a previous user is erased.
