Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple mobile devices are tested individually, then testing thoroughness is maintained, but testing time and cost increase significantly
Solution Approach 1:
The testing system is segmented into multiple independent test stations, each capable of testing one mobile device simultaneously. Each test station includes a test computer, retention device, and necessary test equipment, allowing parallel execution of identical test protocols on multiple devices without compromising testing thoroughness
Solution Approach 2:
Multiple test stations are merged into a unified testing framework that shares common infrastructure elements such as the control computer, software licensing, and test protocols. This consolidation allows simultaneous testing of multiple devices while reducing overall system cost and complexity compared to completely independent test setups
2Productivity
If multiple mobile devices are tested simultaneously using individual setups, then testing throughput increases, but device complexity and cost increase
Solution Approach 1:
The test computers and retention devices are designed as universal, multi-functional units that can test various types of mobile devices (smartphones, tablets, wearables) using the same hardware platform. This universality allows high testing throughput without proportionally increasing system complexity, as the same equipment handles diverse device types
Solution Approach 2:
A control computer acts as an intermediary between the operator and multiple test computers, centralizing control and coordination functions. This intermediary manages test scheduling, result aggregation, and system configuration, allowing simultaneous testing of multiple devices without requiring complex direct control of each individual test station
3Measurement precision
If traditional testing methods are used for sophisticated mobile devices, then testing accuracy is maintained, but testing cost and time increase
Solution Approach 1:
The system uses software-based test protocols and virtual instrumentation that can be replicated across multiple test stations without requiring expensive custom hardware for each station. Test procedures are copied and executed digitally, maintaining measurement precision while significantly reducing the cost of deploying multiple test capabilities
