Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coordination between peripheral devices connected to a computer via different interfaces, such as USB and RS-232, often results in program confusion due to varying delay times and transmission speeds, leading to inefficiencies and increased labor costs as manual timing adjustments are needed to synchronize devices like scanning guns and marking machines.
Innovation Solution
A delay control device with a trigger port, control module, and timing module that disconnects and reconnects interfaces based on a trigger signal and timing duration, allowing for synchronized operation by inputting standby and clock signals, thereby controlling the time interval for instruction execution and preventing program confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peripheral devices are connected via different interfaces (USB, RS-232) with varying transmission speeds, then device connectivity and functionality are improved, but program confusion and coordination errors occur due to timing mismatches
Solution Approach 1:
The patent introduces a delay control device as an intermediary component connected between peripheral devices and the computer system. This mediator device includes a trigger port for receiving trigger signals, a control module for managing connection states, and a timing module for precise delay control. The intermediary synchronizes communication between devices using different interfaces by introducing controlled time delays, thereby preventing program confusion while maintaining interface versatility
Solution Approach 2:
The delay control device performs preliminary timing adjustments before data transmission occurs. The timing module pre-calculates and applies the necessary delay duration based on the specific interface characteristics and device requirements. This preliminary action ensures that subsequent communications are properly synchronized, preventing coordination errors before they occur
2Reliability
If manual timing adjustments are made to synchronize peripheral devices, then program coordination is improved, but labor costs and operational complexity increase
Solution Approach 1:
The delay control device is designed to automatically determine and apply the appropriate delay duration without requiring manual intervention. The timing module self-adjusts based on pre-configured parameters or real-time detection of device characteristics. This self-service capability eliminates the need for operators to manually calculate and adjust timing parameters, reducing labor costs while maintaining reliable synchronization
Solution Approach 2:
The device incorporates feedback mechanisms where the control module monitors communication status and device responses. Based on this feedback, the timing module dynamically adjusts delay durations to optimize synchronization. This closed-loop feedback system ensures reliable coordination while eliminating manual adjustments, as the system self-corrects based on actual performance
3Productivity
If connection between interfaces is maintained continuously, then data transmission efficiency is improved, but timing conflicts and program errors occur due to speed differences
Solution Approach 1:
The delay control device implements periodic disconnection and reconnection of interface connections based on timing requirements. The control module selectively disconnects connections during periods when timing conflicts are expected, and reconnects them when synchronization is achieved. This periodic action pattern prevents communication errors while minimizing interruptions to data transmission, maintaining productivity without sacrificing reliability
