Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-performance processor is used for complex data processing in the testing apparatus, then the data processing capability is improved, but the cost of the apparatus increases
Solution Approach 1:
The patent extracts the complex data processing function from the testing apparatus and relocates it to an external intelligent device (such as a smartphone or computer). The testing apparatus only performs simple data collection and transmission, while the intelligent device handles the complex processing, analysis, and display of touch screen testing data through its own processor and display screen.
Solution Approach 2:
The patent introduces an external intelligent device as an intermediary between the testing apparatus and the user. This intermediary device performs the complex data processing and provides additional functionalities such as graphical display, data analysis, and user interface interactions, allowing the testing apparatus itself to remain simple and cost-effective.
2Speed
If a high-performance processor is used for complex data processing, then the processing speed is improved, but the power consumption increases
Solution Approach 1:
The patent extracts the power-intensive processing operations from the testing apparatus and transfers them to an external intelligent device that has its own power source. This allows the testing apparatus to use a low-power microcontroller while maintaining fast processing speeds through the external device's more powerful processor.

AI summary
The present disclosure provides an apparatus and system for testing a touch screen, and an apparatus for controlling test of a touch screen. The apparatus for testing a touch screen comprises: a processor, a test signal collection interface unit, and an external communication interface unit, wherein the processor is connected to the test signal collection interface unit, and is configured to, after touch information is collected by the test signal collection interface unit, convert the collected touch information into a format which is recognizable by an intelligent device, and transmit the converted touch information to the intelligent device through the external communication interface unit. The apparatus for testing a touch screen according to the present disclosure enables the touch information to be correspondingly processed and displayed by a processor and a display of the intelligent device, respectively. In this way, as the processor of the apparatus for testing a touch screen per se needs not to perform corresponding data processing and analysis processes, a processor with low performance may be used to facilitate reducing the manufacturing cost of the apparatus for testing a touch screen.
