Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturer-specific QR code measurement systems are implemented, then data transmission capability is achieved, but scalability is limited and implementation cost increases
Solution Approach 1:
The patent implements a universal data transmission interface based on standard QR code technology that can work with multiple different sensor types and manufacturers. The electronic device reads QR codes from various external devices and objects, enabling one interface to serve multiple functions and applications across different product lines, thereby achieving scalability without requiring manufacturer-specific implementations for each device type
2Reliability
If QR code-based measurement systems are designed from the start, then data transmission functionality is achieved, but implementation expense increases
Solution Approach 1:
The patent introduces an intermediary electronic device that acts as a bridge between simple external devices lacking QR code capability and the data transmission system. This intermediary handles the QR code reading and data processing, allowing external devices to remain simple and inexpensive while still achieving robust data transmission functionality through the mediating electronic device
3Ease of operation
If user interfaces are simplified, then ease of operation improves, but device controllability and setting flexibility are reduced
Solution Approach 1:
The patent implements a dynamic user interface that can adapt its complexity based on the specific external device being controlled. The system can present simplified interfaces for basic operations while providing access to advanced settings and control options when needed, allowing the interface to be simple for routine use but comprehensive when device control and customization are required
