Multi-Radio Test Fixture Parallel Module Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional testing methods for complex communication devices with multiple radio modules are time-consuming due to the need for separate testing of each module's parameters and characteristics using specific devices and interfaces, limiting the ability to test all modules simultaneously.
Innovation Solution
A multi-radio test method and fixture that connects multiple modules to a test fixture with various interfaces, determines which tests can be performed simultaneously, calculates a numerical value to prioritize tests based on time utilization, and suspends non-priority tests to minimize idle time and overall testing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate testing devices and interfaces are used for each radio module, then testing accuracy and reliability are improved, but testing time increases significantly
Solution Approach 1:
The patent combines multiple separate testing devices and interfaces into a single integrated test fixture that can simultaneously test multiple radio modules. The test fixture includes multiple interface units that can connect to different modules (WiFi, Bluetooth, GPS, etc.) and perform tests in parallel, thereby maintaining testing reliability while significantly reducing total testing time.
Solution Approach 2:
The test fixture is designed as a universal testing system that can accommodate multiple types of radio modules through configurable interface units. Each interface unit can be adapted to work with different module types, allowing the same test fixture to perform specialized tests for various modules simultaneously, thus improving efficiency without compromising test accuracy.
2Reliability
If all parameters and characteristics of each module are tested sequentially, then comprehensive testing is ensured, but productivity decreases
Solution Approach 1:
The testing process is segmented into multiple independent test channels, each capable of testing different radio modules simultaneously. The test fixture divides the testing workload across multiple interface units, allowing comprehensive parameter testing to occur in parallel rather than sequentially, thereby maintaining completeness while improving productivity.
Solution Approach 2:
The system enables continuous testing by eliminating idle time between module tests. While one module is being tested on a particular interface unit, other interface units continue testing different modules. The control unit coordinates test scheduling to ensure continuous utilization of all testing resources, maximizing productivity without sacrificing comprehensive parameter coverage.
3Productivity
If a single test fixture with multiple interfaces is used, then testing efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit serves as an intermediary that manages the complexity of coordinating multiple interface units and radio modules. It automatically schedules tests, assigns modules to appropriate interface units, and coordinates simultaneous testing operations, thereby handling the system's inherent complexity while presenting a simplified operation interface to users.
Solution Approach 2:
The test fixture uses standardized interface unit designs that can be replicated and configured for different module types. Rather than designing unique complex hardware for each module combination, the system employs copyable interface templates that can be adapted through software configuration, reducing overall system complexity while maintaining versatility.

AI summary
A method for testing characteristics of a communication device that includes a plurality of modules using a test fixture includes the steps of connecting the communication device to the test fixture, determining if tests to be performed on the plurality of modules can be simultaneously performed, performing the tests to be performed on the plurality of modules for any tests that are determined can be simultaneously performed, calculating a numerical value for each of the plurality of modules if it is determined that the tests to be performed cannot be simultaneously performed, selecting one of the tests based on the calculated numerical value, and performing the selected one of the tests based on the calculated numerical value and suspending the test or tests on the remaining modules of the plurality of modules other than the selected one of the tests.
