Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine work tools require reconfiguration when switching between interchangeable attachments, as each tool necessitates different control parameters, leading to inefficiencies in operation and identification.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual identification and configuration methods are used for interchangeable work tools, then system complexity is reduced, but identification efficiency and accuracy deteriorate
Solution Approach 1:
The work tool attachments perform self-identification by automatically transmitting their identification data and motion interval counts to the machine receiver, eliminating the need for manual identification operations by the operator
Solution Approach 2:
The patent replaces manual mechanical identification processes with an automated wireless identification system using transmitters, receivers, and electronic processing to identify and configure work tools
2Measurement precision
If automated identification systems with motion detectors and counters are implemented on each work tool, then identification accuracy is improved, but device complexity increases
Solution Approach 1:
The data transmission device is designed as a universal multi-functional unit that combines identification data storage, motion detection, interval counting, and wireless transmission capabilities into a single attachment-mounted system
Solution Approach 2:
The patent introduces wireless communication as an intermediary mechanism between the work tool attachments and the machine controller, enabling automatic data exchange without direct physical connection or complex wiring
3Reliability
If the system continuously monitors and sorts multiple work tool attachments, then identification reliability is improved, but energy consumption increases
Solution Approach 1:
The wireless transmitter operates periodically rather than continuously, transmitting identification data and interval counts at scheduled intervals, which reduces energy consumption while maintaining reliable identification
Solution Approach 2:
The system maintains continuous identification capability through periodic updates, ensuring the machine always has current information about attached work tools without requiring constant active transmission

AI summary
A work tool identification system for identifying the work tool attachment attached to a machine from among a plurality of interchangeable work tool attachments utilizes a data transmission device located on the work tool attachment and an electronic machine controller that may be located on the machine. The data transmission device may store work tool identification data and may measure an interval count indicative of the lapsed time since the work tool attachment was initially moved by a machine. The electronic machine controller generates and sorts a work tool identification list of the plurality of work tool attachments based on the interval count with the lowest interval count appearing before any higher interval counts that is indicative of a recently coupled work tool.
