Portable Tool Control Through Contactless Workpiece Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work management systems cannot control tools on a work object basis before work commences, as they require post-work acquisition of work information, making pre-work tool control challenging.
Innovation Solution
A tool system with a portable tool and identification unit that uses contactless methods to identify the current work object, allowing for pre-work control by capturing images and processing them to determine the appropriate torque settings and procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If work information is acquired separately from the tool after work is done, then the work management system can record and store work information, but it cannot control the tool on a work object basis before the work is started
Solution Approach 1:
The system performs preliminary identification of the work object using an identification unit (such as RFID reader or barcode scanner) before the work is executed. This allows the control unit to retrieve pre-stored work information associated with the identified work object and configure tool parameters in advance, enabling pre-work tool control while maintaining work information accuracy.
Solution Approach 2:
The patent introduces a work object identification unit as an intermediary between the tool and the work management system. This identification unit enables the system to recognize and retrieve work-specific information before work begins, serving as a bridge that allows pre-work control without compromising the reliability of work information recording.
2Loss of information
If the system stores work information, location information, and work object information in association after work is completed, then comprehensive work data is available, but real-time pre-work control capability is lost
Solution Approach 1:
The system performs preliminary identification and information retrieval before work execution. The control unit obtains work information, location information, and work object information in advance by identifying the work object and querying pre-stored data, thereby reducing pre-work preparation time while maintaining complete work data recording capabilities.
Solution Approach 2:
The system dynamically adapts its information acquisition process based on the identified work object. By using the identification unit to recognize the specific work object, the system can selectively retrieve only the necessary work information, location information, and parameters needed for that particular task, optimizing data completeness while minimizing preparation time.

AI summary
An object of the present invention is to provide a tool system allowing a tool to be controlled on a work object basis before the work is started. A tool system includes a portable tool and an identification unit. The tool includes a driving unit to operate with power supplied from a battery pack. The identification unit identifies, by a contactless method, a current work object, to which the tool is set in place, out of a plurality of work objects.
