Solution Overview
Problem
Current cutting tool management systems are time-consuming and prone to errors due to the lack of proper functionalities in existing tool carts, requiring manual intervention for tool checking and management, which is inefficient and inaccurate.
Innovation Solution
An intelligent tool cart equipped with sensors, indicator lights, a control module, and a wireless communication device that automates the process of tool selection, loading, and mounting, ensuring correct tool usage by reading identification data and communicating with machine tools and a system application program to manage cutting tool deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual recording and checking of cutting tools is used, then flexibility and adaptability are maintained, but time consumption and error rates increase
Solution Approach 1:
The cutting tool cart autonomously performs verification of tool correctness through its controller comparing tool identification data with required tool data, eliminating the need for manual verification by operators. The system self-checks whether the carried cutting tools match the work order requirements, thereby improving both efficiency and accuracy simultaneously.
Solution Approach 2:
The controller receives feedback from the identification data reading device and automatically verifies whether the cutting tools are correct by comparing with work order information. This closed-loop feedback mechanism ensures high reliability in tool verification while maintaining fast operation speeds.
2Reliability
If automated verification systems are implemented, then tool verification accuracy improves, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it controls the identification data reading device, stores work order information, performs verification logic, and communicates with the central management system. By making the controller multi-functional, the system achieves high verification reliability without adding separate dedicated verification devices, thus avoiding increased complexity.
Solution Approach 2:
The verification function is merged into the existing controller of the cutting tool cart rather than being implemented as a separate system. The controller integrates tool identification reading, data storage, verification logic, and communication functions, simplifying the overall system structure while maintaining high verification accuracy.
3Ease of operation
If manual tool management is used, then device complexity remains low, but time consumption and labor requirements increase
Solution Approach 1:
The manual mechanical process of recording and verifying cutting tools is replaced with an automated electronic system. The controller automatically reads tool identification data, retrieves required tool information from work orders, and verifies correctness without manual intervention, dramatically reducing tool change time while keeping the operation simple through automated processes.
4Reliability
If proper tool checking functionalities are added to tool carts, then tool verification accuracy improves, but manufacturing complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions including tool verification, data storage, and communication, which are integrated into a single component during manufacturing. This multi-functionality approach allows the cart to achieve high verification accuracy without requiring separate dedicated verification devices, simplifying the manufacturing process.

AI summary
An intelligent tool cart (1) includes a body (2), a wireless communication device (5), a plurality of tool holders (6), a temporary tool holder (8), and a tool reading holder (4); wherein each tool holder (6) in the plurality of tool holders (6) has an indicator light (7) and a sensor to sense whether a cutting tool (3) is loaded, the tool reading holder (4) is used for accommodating and reading cutting tool identification data of to-be-mounted to or to-be-dismounted cutting tools. A cutting tool change method provides an intelligent tool cart (1), a system APP, a cutting tool deployment information, and a list of cutting tool demand information of a designated machine tool. The system APP instructs to load cutting tools to the intelligent tool cart (1), and to take cutting tools from tool holders (6) to cutting tool positions of the designated machine tool.
