Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The frequent need to upgrade portable information handling devices due to rapid technological advancements leads to high replacement costs and inefficiencies, especially in lease and device-as-a-service arrangements, where unauthorized access and resource utilization issues are challenging to manage.

Innovation Solution

A physical locking mechanism is integrated into computing devices to prevent the cover from being opened, ensuring unauthorized access is blocked by activating the mechanism upon receiving an indication from a device lock system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a physical locking mechanism is added to prevent unauthorized access, then device security is improved, but device complexity increases

Engineering Contradiction:

Improvedevice securityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical locking systems with a simpler mechanism that uses magnetic fields or electrical signals to activate a physical latch. The locking mechanism is triggered electronically through a processor that receives signals from a device lock system, substituting complex mechanical control with a more manageable electro-mechanical system that maintains security while reducing overall complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The physical locking mechanism is integrated into the existing device architecture, serving multiple functions: preventing unauthorized access to the cover, securing the device during lease periods, and working in conjunction with software-based device lock systems. This multi-functionality approach allows a single added component to address various security scenarios without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If frequent device replacement is implemented to keep up with technology advancements, then device performance is improved, but cost increases

Engineering Contradiction:

Improvedevice performanceVSAvoidreplacement cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements preliminary control measures by activating physical locking mechanisms before devices are handed to users in lease arrangements. This prevents unauthorized access and potential damage from the outset, reducing the likelihood of device failure and extending device lifespan. By preventing unauthorized modifications or access early in the device lifecycle, organizations can maintain devices longer without frequent replacements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent converts the potential harm of unauthorized access and device misuse into a benefit by using the locking mechanism to control and monitor device usage. The very feature that restricts access (the lock) also protects the device from damage, theft, or unauthorized modifications, thereby extending device life and reducing replacement frequency and costs.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
