Solution Overview

Problem

Current tool control systems face challenges in accurately verifying the contents of tool kits, managing access security, and efficiently auditing and filtering event data, particularly in high-security environments like the aerospace industry, where tools must be accounted for to prevent foreign object damage and theft.

Innovation Solution

An automated tool control system equipped with image sensing devices, multi-factor authentication, and advanced data processing capabilities to capture and process images of storage locations, verify kit contents, and apply sophisticated filtering techniques for audit images, ensuring accurate inventory management and secure access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sensors are disposed in storage locations to detect tool presence, then inventory tracking capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improveinventory tracking capabilityVSAvoidnumber of sensors
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple sensor functions into a single image-based sensing device. Instead of using separate contact sensors, magnetic sensors, or infrared sensors for each storage location, the system uses one image sensing device to capture and process images of multiple storage locations simultaneously, determining inventory status from the captured images.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces physical contact sensors with an optical/image-based detection system. The image sensing device captures visual information of storage locations and uses image processing to determine tool presence and identity, eliminating the need for mechanical or contact-based sensors at each location.

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

2Productivity

If sensors are used to detect tool presence in storage locations, then inventory monitoring is improved, but reliability decreases due to false alarms from sensor damage or malfunction

Engineering Contradiction:
Improveinventory monitoringVSAvoidfalse alarm rate
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces contact-based sensors that are prone to damage and malfunction with a non-contact image-based detection system. The image sensing device and processing system provide more reliable detection by analyzing visual characteristics of tools and storage locations, eliminating the mechanical failure modes of traditional sensors.

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

Solution Approach 2:

The system creates visual copies (images) of the storage locations and tools for analysis. Instead of relying on physical sensors that can fail, the system captures and processes image data to determine tool presence and identity, providing a more reliable detection method that can be archived and reviewed.

Inventive Principle:
Principle #26Copying

3Measurement precision

If manual inventory checks are performed to verify tool contents, then accuracy of tool verification is improved, but loss of time increases

Engineering Contradiction:
Improvetool verification accuracyVSAvoidaudit time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs automated self-verification of tool inventory by capturing images of storage locations and automatically processing these images to determine tool presence, identity, and kit contents. The data processing system autonomously compares detected tools against expected inventory without requiring manual inspection, providing both accuracy and time efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual visual inspection with automated image capture and processing. The image sensing device and data processing system work together to automatically verify tool contents, eliminating the time-consuming manual checking process while maintaining or improving verification accuracy through consistent automated analysis.

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

4Ease of operation

If a single authentication method is used for system access, then ease of operation is improved, but security decreases in high-security environments

Engineering Contradiction:
Improveaccess convenienceVSAvoidsecurity level
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the authentication process into multiple independent factors or methods. Instead of using a single authentication mechanism, the system implements multi-factor authentication where users must provide multiple forms of verification (such as something they know, something they have, or something they are) to gain access, thereby enhancing security while maintaining operational ease through automated processing.

Inventive Principle:
Principle #1Segmentation
