Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection devices for active glare protection systems in welding environments face challenges in achieving high transmission speed and reliability of welding parameters, particularly due to the need for additional information like CRC and Syncword in package-oriented transmissions, which increases latency and complexity.
Innovation Solution
A detection device with a communication unit configured for transmitting welding parameters as bit sequences of defined length, allowing for faster and more reliable data transfer without the need for additional information like CRC and Syncword, using a proprietary, non-packaged transmission method with a modulation rate of at least 100 kbit/s, and a uni-directional streaming process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If package-oriented transmission with additional information (CRC, Syncword) is used, then transmission reliability is improved, but transmission speed and latency are worsened
Solution Approach 1:
The patent extracts and removes the additional information elements (CRC, Syncword, package structure) from the transmission protocol, keeping only the essential data bits. This extraction eliminates the time-consuming overhead while maintaining the core transmission function, thereby reducing latency without compromising the essential reliability of the welding parameter data transfer.
Solution Approach 2:
The patent changes the transmission parameter from package-oriented format to raw bit sequence format. By altering the data structure parameter and transmission protocol parameters, the system achieves faster transmission speeds while adapting the receiver to interpret the simplified bit sequences directly as welding parameter values.
2Reliability
If package-oriented transmission with additional information is used, then transmission reliability is improved, but device complexity is worsened
Solution Approach 1:
The patent extracts and eliminates the complex package structure, CRC calculation units, and synchronization word processing from the transmission system. By removing these complexity-inducing elements and keeping only the essential data transmission function, the system simplifies both the transmitter and receiver while maintaining sufficient reliability for the application.
Solution Approach 2:
Instead of following the conventional approach of adding overhead information for reliability, the patent inverts the approach by stripping away all non-essential elements and relying on the inherent robustness of the wireless connection and the critical nature of the transmitted welding parameter data to ensure transmission reliability.
3Speed
If bit sequences of defined length are transmitted, then transmission speed is improved, but robustness against interference signals is worsened
Solution Approach 1:
The patent transmits more bits than the absolute minimum required by using defined-length bit sequences (e.g., 8 bits for byte-aligned parameters). This excessive transmission of bits provides redundancy that enables error detection and correction capabilities, allowing the system to maintain high speed while achieving sufficient robustness against interference through the increased bit representation.
