Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional data transfer methods (Bluetooth, wired connection, memory card swapping) are used, then data transfer functionality is provided, but device complexity and operational complexity increase due to multiple protocols and hardware requirements
Solution Approach 1:
The patent applies universality by making the touchscreen module serve multiple functions: it acts as both a user interface display and a wireless data transfer component. The transmitting feature and receiving feature are integrated into the touchscreen module, eliminating the need for separate dedicated wireless transfer hardware and reducing overall device complexity while maintaining data transfer versatility
Solution Approach 2:
The patent merges the data transfer functionality with the existing touchscreen module structure. By combining the transmitting feature and receiving feature into the touchscreen module, the patent eliminates the need for separate Bluetooth modules, wired interfaces, or additional hardware components, thereby simplifying the device configuration while providing comprehensive data transfer capabilities
2Productivity
If traditional data transfer methods are used, then data sharing is achieved, but transfer efficiency and simultaneity are limited due to sequential operation requirements
Solution Approach 1:
The patent enables continuous and simultaneous data transfer by using capacitive coupling between the transmitting and receiving features of the touchscreen modules. This allows bidirectional communication to occur continuously without interruption or sequential handshaking delays, significantly improving transfer efficiency and reducing the time lost to protocol negotiations and sequential operations
3Reliability
If additional hardware is added to improve data transfer capabilities, then transfer functionality is enhanced, but device cost and complexity increase
Solution Approach 1:
The patent applies self-service by utilizing the existing touchscreen module's capacitive sensing capability to enable wireless data transfer. The transmitting feature and receiving feature are integrated into the touchscreen module itself, eliminating the need for separate dedicated wireless transfer hardware. This approach enhances data transfer reliability while avoiding the added cost and complexity of additional hardware components
