Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the output of the mobile RFID reader is increased to extend recognition distance, then the recognition distance may be extended, but the portability and ease of operation are compromised
Solution Approach 1:
The RFID reader is divided into distinct functional modules: a handheld operation unit and a separate antenna unit. This segmentation allows the antenna to be optimized for recognition distance while the handheld unit maintains portability and ease of operation.
Solution Approach 2:
A coupling structure serves as an intermediary between the handheld unit and the antenna, enabling flexible connection and disconnection. This intermediary component allows the system to achieve extended recognition distance through the antenna while maintaining the portability of the handheld unit during transportation.
2Reliability
If the area of the antenna is extended to improve recognition rate, then the recognition rate may be improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The antenna is designed with flexible connection capabilities, allowing it to be dynamically adjusted and positioned during operation. This dynamic design enables the antenna to achieve optimal recognition rate without requiring a permanently fixed complex structure.
Solution Approach 2:
The coupling structure serves multiple functions: it connects the handheld unit to the antenna, allows for easy assembly and disassembly, and provides flexible positioning. This multi-functionality reduces overall device complexity while maintaining high recognition rate.
3Ease of operation
If the mobile RFID reader is designed for easy handheld operation, then the ease of operation is improved, but the antenna area is limited
Solution Approach 1:
By separating the handheld unit from the antenna unit, the design allows the antenna to have a larger area for improved recognition rate, while the handheld unit remains compact and easy to manipulate during operation.
Solution Approach 2:
The system transitions from a single integrated unit to a multi-component system connected in space. This dimensional change allows the antenna to extend in area for better recognition while the handheld unit maintains its compact form factor for ease of operation.
