Wireless Master-Slave Communication for Machine Tool Function Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems rely on complex cable laying for communication, which is cumbersome and poses safety hazards, while also limiting user-friendliness and flexibility in operation.
Innovation Solution
Implementing a wireless communication system where tool function modules and accessory devices can be assigned master or slave functions, allowing hierarchical communication and eliminating the need for cables, with functionality controlled via user interfaces and detection units for parameter-based operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is implemented between tool function module and accessory devices, then user-friendliness and safety are improved by eliminating cables, but device complexity increases due to the need for wireless communication units and hierarchical master/slave assignment protocols
Solution Approach 1:
The patent replaces the mechanical cable-based communication system with a wireless communication system. Tool function modules and accessory devices communicate via wireless signals (e.g., Bluetooth, Wi-Fi) instead of physical cables, eliminating the need for cable routing and connection while enabling data transmission and control functions.
Solution Approach 2:
The patent implements a universal master/slave assignment protocol that can be applied across different tool function modules and accessory device combinations. This standardized hierarchical communication framework provides multi-functional compatibility, allowing any master device to control any slave device through the same assignment mechanism regardless of specific device types.
2Ease of operation
If hierarchical master/slave assignment is implemented for wireless communication, then communication structure is simplified and control is improved, but loss of time occurs during the assignment process
Solution Approach 1:
The patent enables preliminary automatic device discovery and pre-assignment of master/slave roles before actual operation begins. When devices are powered on or enter communication range, they automatically detect each other and establish hierarchical relationships in advance, so that when operation starts, the communication structure is already in place without requiring time-consuming manual assignment.
Solution Approach 2:
The patent implements self-service automatic assignment mechanisms where devices autonomously determine their own master or slave roles based on predefined criteria (e.g., device type, capability priorities, random selection). The system automatically resolves conflicts and establishes hierarchical relationships without user intervention, eliminating manual assignment time while maintaining structured communication.
