Tool Tracking Assembly for Cross-Machine Usage History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tools used in industrial machines, such as punch presses, press brakes, and compression machines, face challenges in tracking their use history, particularly the hit/stroke count, when removed from presses and used in different machines, leading to difficulties in maintenance planning, tool location, and compliance with regulations.
Innovation Solution
A tracking assembly is provided that includes a sensor and counter, either mechanically or electronically triggered by force applied during machining operations, allowing continuous tracking of the tool's use history, even when removed from the press, using mechanisms like collars, trays, or sheathed configurations with Bluetooth Low Energy (BLE) integration for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tools are removed from presses and used in different machines, then tool versatility and adaptability are improved, but tracking and locating the tools becomes more difficult and time-consuming
Solution Approach 1:
The patent uses RFID tags and readers to create electronic copies/representations of tool location and usage data. Instead of physically tracking tools, the system creates digital records that can be queried instantly, resolving the contradiction between tool mobility and trackability
Solution Approach 2:
The RFID tags serve as intermediaries between the tools and the tracking system. These passive tags attach to tools and can be read by readers at various press locations, enabling indirect tracking without affecting tool versatility or requiring active components on the tools themselves
2Adaptability or versatility
If tools are frequently exchanged between machines, then production flexibility is improved, but maintenance planning becomes more difficult due to lost usage history
Solution Approach 1:
The system creates electronic copies of usage history data stored in RFID tags and centralized databases. This digital replication ensures that usage information travels with the tool or can be retrieved regardless of tool location, preventing information loss during frequent exchanges
Solution Approach 2:
The tracking system provides continuous feedback on tool usage through automated counting mechanisms that record each press operation. This real-time data collection enables proactive maintenance planning by alerting operators when tools approach their usage limits, regardless of how frequently tools are moved between machines
3Device complexity
If manual tracking methods are used for tools, then device complexity is reduced, but measurement precision and reliability of usage data deteriorates
Solution Approach 1:
The tracking system is designed to be self-activating through sensor detection of tool installation and automated counting of press operations. Once deployed, the system requires minimal human intervention to collect and record usage data, maintaining both simplicity and precision simultaneously
Solution Approach 2:
The patent replaces manual mechanical tracking methods with automated sensor-based detection and electronic data recording. This substitution eliminates human error in counting and recording usage while maintaining relatively simple system architecture through the use of standard sensors and databases
