Solution Overview

Problem

Existing tool management systems in business premises are inefficient, as tools often go missing due to unclear ownership and access issues, and current solutions like locked cabinets require significant manual monitoring, which is labor-intensive and costly, especially in large companies.

Innovation Solution

A tool dispensing system that includes a central data management system, user database, electronic locks, and key devices, allowing users to request tool access via a user interface, which grants temporary opening authorizations based on access permissions, ensuring only authorized users can access tools and tracks their location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tool cabinets are locked and only one responsible employee has a key, then tool security is improved and unauthorized access is prevented, but additional manual monitoring work is required and implementation becomes difficult in large companies

Engineering Contradiction:
Improvetool securityVSAvoidmanual monitoring work
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service tool access where users independently request tools through a user interface, receive automatic authorization decisions from the data management system, and access tools without manual intervention from responsible employees. The electronic lock system automatically validates requests and grants access based on pre-configured access rights.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical key-based access control system is replaced with an automated electronic system. The electronic lock communicates with the data management system via data interfaces, eliminating the need for physical key distribution and manual monitoring while maintaining security through electronic authorization validation.

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

2Reliability

If automatic inventory management systems are integrated into tool cabinets, then tool tracking reliability is improved, but acquisition costs increase significantly

Engineering Contradiction:
Improvetool trackingVSAvoidacquisition cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The inventory management functionality is extracted from the tool cabinet hardware and implemented as a separate software-based data management system. The electronic lock and data management system work together to provide tracking capabilities without requiring expensive integrated hardware solutions in each tool cabinet.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of implementing expensive physical sensors and automated detection systems in each tool cabinet, the system uses data records and information copies stored in the data management system to track tool locations and status, providing equivalent tracking functionality at lower cost.

Inventive Principle:
Principle #26Copying

3Ease of operation

If permanent access authorization is granted to employees, then ease of tool access is improved, but tool security and tracking control are reduced

Engineering Contradiction:
Improvetool accessVSAvoidaccess control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The access authorization system transitions from static permanent permissions to dynamic temporary authorizations. Access rights are automatically created for specific time periods based on user requests and pre-configured access rights, allowing the system to adapt access control to actual needs while maintaining security.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a tool dispensing system (2), a method for managing and dispensing tools (52), and the use of an electronic lock (10). The tool dispensing system (2) comprises a user interface (30) through which a user request (50) concerning a required tool (52) is transmitted to a central data management system (4). The central data management system (4) verifies the user's (53) access authorization and issues the user (53) a temporary opening authorization (22). Using the temporary opening authorization (22), the user (53) can open an electronic lock (10) of a tool storage area (12) containing the required tool (52) within a specified period of time.
