Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for associating blocking devices with machines in woodworking and similar industries are prone to errors, signal interference, and manual data entry issues, leading to working waste, economic losses, and safety hazards due to the complexity and potential for incorrect wireless communication between machines.
Innovation Solution
A method involving a processing unit and transceiver means that compares the power of an association signal with a predetermined threshold to automatically associate blocking devices with a machine, eliminating the need for manual data entry and reducing signal interference by ensuring only compatible devices communicate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data entry methods are used to associate blocking devices with machines, then the association process can be performed, but errors and time consumption increase
Solution Approach 1:
The patent replaces manual mechanical data entry with automatic wireless signal-based association. The blocking device and machine exchange identification signals wirelessly, and the processing unit automatically matches them based on signal strength comparison, eliminating manual input operations entirely.
Solution Approach 2:
The association process becomes self-service through automatic signal exchange and processing. The system autonomously compares received signals with stored thresholds, determines compatibility, and completes association without human intervention, making the system serve itself.
2Device complexity
If wireless communication is used between machine and blocking devices, then wiring complexity is reduced, but signal interference and incorrect command execution occur
Solution Approach 1:
The patent implements feedback through signal strength monitoring and comparison. The processing unit continuously receives wireless signals, compares their strength against predetermined thresholds, and uses this feedback to verify proper association before allowing command execution, ensuring reliability.
Solution Approach 2:
The system performs preliminary association verification through signal strength comparison before enabling command execution. By pre-establishing and comparing signal thresholds during the association phase, the system prevents incorrect commands from being executed on wrong blocking devices.
3Productivity
If automatic signal-based association is implemented, then association speed and precision improve, but signal power threshold management is required
Solution Approach 1:
The patent applies preliminary action by pre-establishing signal power thresholds before the association process begins. These predetermined thresholds are stored in the processing unit and used to automatically evaluate received signals, enabling fast and accurate association without real-time complex calculations.
