Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing is used to validate POS terminal updates, then testing coverage can be comprehensive, but productivity is low and testing is time-consuming
Solution Approach 1:
The patent replaces manual mechanical testing operations with an automated robotic system that uses mechanical actuators to physically interact with POS terminals. The robotic system includes a card insert assembly with actuators that automatically insert/withdraw cards, a data entry assembly with actuators that press keys, and a barcode scanner assembly, eliminating the need for manual mechanical testing operations while maintaining comprehensive testing coverage
Solution Approach 2:
The automated testing system performs self-service by autonomously executing test cases without human intervention. The system automatically navigates through test scenarios, interacts with terminal interfaces, records results, and manages test data, enabling the testing process to serve itself and dramatically increasing productivity from 60 test cases per human tester to 600 test cases per automated system per day
2Adaptability or versatility
If diverse POS terminal types are tested manually, then all form factors can be validated, but testing complexity increases and errors increase
Solution Approach 1:
The patent implements a universal automated testing platform that can test multiple types of POS terminals with different form factors and interfaces through a single robotic system. The system includes configurable assemblies that can adapt to various terminal types, making the testing device itself multi-functional and capable of handling diverse terminal configurations without requiring separate manual testing processes for each type
Solution Approach 2:
The system manages complexity by dynamically changing operational parameters based on the specific terminal type being tested. The automated system can adjust test sequences, interaction methods, and validation criteria according to the terminal's form factor and interface characteristics, allowing comprehensive testing of diverse terminals while maintaining consistent automated process control
3Reliability
If rigorous testing is performed to identify unexpected behavior, then quality is improved, but cost increases
Solution Approach 1:
The patent replaces expensive manual testing labor with an automated robotic system that performs rigorous quality validation at lower cost. The automated system eliminates human errors, provides consistent repeatable testing, and can execute hundreds of test cases daily, reducing the cost per test case while maintaining or improving quality validation thoroughness
Solution Approach 2:
The automated testing system enables continuous operation without the breaks, fatigue, and variability inherent in manual testing. The robotic system can run test suites continuously and repeatedly, providing ongoing quality validation that is more thorough and cost-effective than intermittent manual testing, thereby improving reliability while reducing overall testing costs
