Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an RFID label is applied to the spool, then clip information can be read automatically, but the label can be easily removed or damaged by moving machine parts
Solution Approach 1:
The transponder is integrated inside the hollow-cylindrical spool body, nested within the structure rather than attached externally. This protects the RFID tag from mechanical damage by moving machine parts while maintaining automatic reading capability through the spool material
Solution Approach 2:
A non-conductive coating or material layer acts as an intermediary between the RFID tag and the external environment, shielding the tag from mechanical contact while allowing electromagnetic signals to pass through for reading
2Reliability
If an RFID label is applied to the spool, then clip information can be read automatically, but signal transmission can be interfered with by metallic objects
Solution Approach 1:
A non-conductive coating or dielectric material layer serves as an intermediary shield between the RFID tag and metallic objects in the machine environment, blocking electrical interference while permitting electromagnetic signal transmission for reading the clip information
Solution Approach 2:
The spool structure creates a protected environment around the RFID tag, isolating it from the conductive and interferential environment of the clipping machine, similar to how an inert atmosphere protects sensitive components
3Productivity
If clips are wound tightly on the spool for high storage density, then productivity increases, but the spool structure must withstand higher mechanical stress
Solution Approach 1:
The spool is constructed from composite materials or optimized polymer structures that provide high mechanical strength and stress resistance, enabling the spool to withstand the high mechanical loads from tightly wound clips while maintaining productivity
