Solution Overview

Problem

Mobile Information Handling Systems (IHSs) face increased support burdens due to undetectable accidents, such as hard disk failures, which complicate diagnosis and warranty determination, and existing systems lack efficient post-accident health assurance mechanisms.

Innovation Solution

Implementing a Basic Input/Output System (BIOS) that executes diagnostics routines during reboot upon detecting an accident, using an accident flag or register, and stores results in an ACPI Platform Health Assessment Table (PHAT), with the Operating System (OS) determining further diagnostics and sending results to a remote service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile IHSs are used to increase convenience and versatility, then user mobility and accessibility are improved, but the risk of accidents and hidden damage increases

Engineering Contradiction:
Improveuser mobilityVSAvoidaccident risk
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by detecting accidents through sensors (accelerometers, gyroscopes) and setting accident flags before the user or technician becomes aware of potential damage. This early detection enables proactive diagnostic routines to be executed during reboot, identifying hidden damage before it manifests as operational failures.

Inventive Principle:
Principle #10Preliminary action

2Ease of repair

If traditional diagnostic methods are used after accidents, then diagnosis can be performed, but diagnostic time and support burden increase significantly

Engineering Contradiction:
Improvediagnosis capabilityVSAvoiddiagnostic time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The system executes diagnostic routines automatically during reboot immediately after an accident is detected, performing diagnostics preliminarily before the device is fully operational. This eliminates the need for lengthy post-accident diagnostic sessions, as the system has already assessed component health and prepared a report.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The IHS performs self-diagnosis by automatically executing diagnostic routines, collecting data from sensors and system components, and generating accident reports without requiring technician intervention. This self-service capability significantly reduces support burden and diagnostic time.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If comprehensive diagnostics are executed after every accident, then accurate damage assessment is achieved, but system complexity and processing overhead increase

Engineering Contradiction:
Improvedamage assessment accuracyVSAvoiddiagnostics system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies local quality by setting accident flags and executing diagnostics selectively based on the specific accident context. Rather than uniformly diagnosing all components after every accident, the system identifies which components may be affected by the accident type and severity, focusing diagnostic efforts where needed while reducing unnecessary complexity.

Inventive Principle:
Principle #3Local quality

4Reliability

If accident detection and diagnostic routines are implemented, then post-accident health assurance is improved, but firmware complexity and processing requirements increase

Engineering Contradiction:
Improvepost-accident health assuranceVSAvoidfirmware complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The firmware is segmented into distinct functional modules: accident detection routines, accident flag management, diagnostic routine execution, and report generation. This segmentation allows each component to be independently managed and optimized, reducing overall firmware complexity while maintaining comprehensive post-accident health assurance capabilities.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods for post-accident health assurance in an Information Handling System (IHS) are described. In some embodiments, an IHS may include a processor and a memory coupled to the processor, where the memory comprises program instructions that, upon execution by the processor, cause a Basic Input/Output System (BIOS) to execute a diagnostics routine during a reboot in response to a determination that the IHS suffered an accident prior to the reboot.
