RF Testing System Parallel Switching for Idle Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency of single RF testing machines in mobile phone production leads to significant idle time and high production costs due to the lengthy RF testing process, where only one mobile phone can be tested at a time, resulting in low usage efficiency of the testing equipment.
Innovation Solution
A radio frequency testing system that connects multiple mobile communication devices simultaneously, utilizing an RF testing device, a switch device, and a controlling device to perform pre-set procedures and RF tests in sequence, allowing the RF testing device to be utilized more efficiently by switching between devices during the testing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RF testing machine is used to test mobile phones sequentially, then the testing process can be simplified, but the idle time of the RF testing machine increases significantly (one-quarter of total testing time)
Solution Approach 1:
The patent divides the testing system into multiple independent testing channels by using multiple RF testing machines and switching devices. Each channel can test mobile phones independently, allowing parallel processing and eliminating idle time in the RF testing machine by continuously switching between devices undergoing different testing stages.
Solution Approach 2:
The patent implements preliminary actions by performing setup and configuration procedures for mobile phones before the actual RF testing. Multiple phones can be prepared in parallel during the setup phase, so when RF testing begins, phones are already ready, reducing idle time and improving overall testing efficiency.
2Productivity
If multiple mobile phones are tested simultaneously using multiple RF testing machines, then the usage efficiency of RF testing equipment improves, but the system complexity and cost increase
Solution Approach 1:
The patent creates a universal testing platform where multiple mobile phones can be tested simultaneously using a coordinated system of RF testing machines and switching devices. The controlling device manages multiple testing channels uniformly, allowing the same testing procedure to be applied across different devices and machines, thereby improving productivity without proportionally increasing complexity.
Solution Approach 2:
The patent introduces switching devices and controlling devices as intermediaries between multiple mobile phones and RF testing machines. These intermediaries coordinate the testing process, manage connections, and orchestrate the testing sequence, enabling simultaneous testing of multiple phones while keeping the system manageable through centralized control.
3Reliability
If the RF testing machine waits for mobile phone setup completion, then the testing can be performed accurately, but the testing time increases due to idle waiting period
Solution Approach 1:
The patent performs all necessary setup and configuration actions for mobile phones in parallel before the RF testing begins. Multiple phones undergo setup procedures simultaneously on different channels, so when RF testing starts, all phones are ready and accurate testing can be performed without waiting time, maintaining both reliability and efficiency.
Solution Approach 2:
The patent ensures continuous useful action by maintaining multiple parallel testing channels where phones are continuously being prepared and tested. The RF testing machine continuously switches between devices without idle waiting, as setup actions are completed in advance on other channels, maintaining continuous productive activity throughout the testing process.
