Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional interfaces and programming languages are used for protocol testing, then test scenarios can be implemented, but users require extensive knowledge regarding the mobile-radio protocol and the respectively used interface
Solution Approach 1:
The patent uses visual cards that copy and represent signaling portions in a simplified graphical format instead of requiring users to work with complex programming languages and protocol interfaces. Each card visually represents a signaling message or event, making the testing process accessible to users with limited protocol knowledge.
Solution Approach 2:
The card-based interface acts as an intermediary between the user and the complex protocol testing system. Instead of directly interacting with protocol specifications and programming interfaces, users manipulate visual cards that mediate the testing process, automatically translating card sequences into protocol test scenarios.
2Reliability
If conformance test cases from mobile-radio authorities are used, then standardized testing can be performed, but the preparation becomes very complex and requires special knowledge on the part of the testing personnel
Solution Approach 1:
The patent segments the complex conformance test cases into individual visual cards, each representing a specific signaling portion or protocol event. This segmentation allows users to assemble standardized test scenarios by selecting and arranging discrete card elements, reducing the complexity of preparing comprehensive protocol tests while maintaining reliability.
Solution Approach 2:
The system pre-configures cards with standardized signaling portions and permitted linkages based on protocol specifications. This preliminary preparation of test elements allows users to reliably implement standard conformance tests without needing to manually prepare complex test sequences or understand the underlying protocol complexity.
3Adaptability or versatility
If users implement specially staged scenarios on the device itself, then customized testing can be achieved, but extensive knowledge regarding the mobile-radio protocol and the respectively used interface is required
Solution Approach 1:
The patent implements a dynamic card system where users can freely select, arrange, and modify cards to create customized test scenarios. The system dynamically validates card linkages and provides feedback on permitted sequences, enabling users with limited knowledge to design and implement custom protocol tests by visually assembling card sequences rather than programming.
Data Source
AI summary
A testing device serves for the testing of a device under test. It comprises a control unit (12), a display unit and an operating unit. The control unit is embodied to implement a mutual signaling with the device under test, comprising signaling portions. The control unit (12) further contains a card-generating device (23) for generating cards for display by means of the display unit. In this context, the cards each correspond to a given signaling portion. Prompted by a user entry by means of the operating unit, the card-generating device (23) is also embodied to place cards on the display device in a sequence specified by a user and to specify a sequence of the signaling portions of the signaling to be implemented in this manner.
