Solution Overview

Problem

Diagnosing and correcting information handling system hardware failures is inefficient, often requiring multiple technician interactions and unnecessary replacement of components, as users and technicians frequently fail to utilize diagnostics modules, leading to incorrect component replacements.

Innovation Solution

A diagnostics module generates a unique code that is sent to a service center for validation, allowing for automated dispatch of replacement components without technician involvement, ensuring accurate diagnosis and reducing unnecessary shipments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If technicians manually diagnose hardware failures through phone conversations, then they can provide personalized assistance, but the service cost increases and diagnosis accuracy decreases

Engineering Contradiction:

Improvediagnosis accuracyVSAvoidservice cost

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The system enables self-service by automatically generating diagnostic codes from the information handling system itself, eliminating the need for technician intervention in the diagnosis process. The diagnostics module autonomously identifies hardware failures and generates unique codes that directly trigger replacement procedures.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical/human diagnostic process with an automated electronic system. Instead of technicians manually analyzing system behavior through phone conversations, an electronic diagnostics module automatically detects failures, generates codes, and initiates replacement workflows.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If technicians manually analyze each failure case, then complex problems can be addressed, but technician time is wasted on simple replacements

Engineering Contradiction:

Improveservice efficiencyVSAvoidtechnician talk time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The service process is segmented into automated and manual components. Routine diagnostic code generation and simple replacement cases are automated, while technician intervention is reserved for complex cases that cannot be resolved through automated processes alone.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the state of service delivery from manual analysis to automated code-based processing. By transforming diagnostic information into standardized codes, the system enables automated routing and processing, fundamentally changing how service requests are handled.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If diagnostics modules are mandatory, then diagnosis accuracy improves, but user compliance decreases

Engineering Contradiction:

Improvediagnosis accuracyVSAvoiduser compliance

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs preliminary diagnostic actions automatically before requiring user action. The diagnostics module pre-identifies failures and generates codes in advance, so users simply need to provide the code rather than perform complex diagnostics themselves.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The diagnostic code serves as an intermediary between the complex diagnostic process and the user. Instead of requiring users to understand or perform diagnostics, the system uses codes as a mediator that simplifies user interaction while maintaining diagnostic accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Extent of automation

If automated diagnostic codes are implemented, then service automation increases, but verification of code authenticity becomes necessary

Engineering Contradiction:

Improveservice automationVSAvoidverification system complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The system implements feedback loops where diagnostic codes are verified against system records to ensure authenticity. The verification process provides feedback on code validity, and the system automatically adjusts its response based on whether the code is authentic or potentially fraudulent.

Inventive Principle:

Principle #23Feedback

AI summary

Hardware component failure diagnosis of an information handling system is verified with a hardware diagnostics code generated by a diagnostics module integrated with an information handling system and sent from the information handling system to a diagnostics engine of a service center. The hardware diagnostics code includes a unique identifier for the information handling system and a hardware component failure code that identifies the type of hardware and type of failure. The diagnostics engine analyzes the hardware diagnostics code to confirm that diagnostics were run on the information handling system and, for authentic hardware failures, automatically initiates the sending of a replacement hardware component to the information handling system.
