Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If detection labels are produced in different versions or replaced frequently to accommodate system updates, then compatibility with updated systems is improved, but production costs increase and operational efficiency decreases
Solution Approach 1:
The patent applies the dynamics principle by enabling the detection label to dynamically change its operational characteristics through remote configuration. The label can switch between different operational modes (passive resonant circuit only, active circuit only, or both) based on system requirements, eliminating the need for physical replacement when systems are updated. This dynamic adaptability resolves the contradiction by allowing a single label design to serve multiple system versions.
Solution Approach 2:
The patent implements parameter changes by modifying the operational parameters of the detection label through remote configuration commands. The label's resonant frequency, circuit activation state, and communication protocols can be adjusted via the active circuit to match different system versions. This allows the same physical label to adapt to system updates without requiring production of new label versions.
2Adaptability or versatility
If detection labels are replaced or produced in different versions for system updates, then system compatibility is improved, but production costs increase
Solution Approach 1:
The patent applies universality by designing a detection label that can perform multiple functions through a single device. The label incorporates both a passive resonant circuit for basic identification and an active circuit for enhanced communication and configuration capabilities. This multi-functional design allows one universal label type to work across different system versions, eliminating the need for multiple specialized label versions and reducing production costs.
3Reliability
If the passive resonant circuit is always active for identification, then detection capability is improved, but interference with system operations increases
Solution Approach 1:
The patent applies dynamics by enabling the passive resonant circuit to switch between active and inactive states based on operational context. The active circuit can remotely control the activation of the passive resonant circuit, allowing it to remain inactive during certain system operations to avoid interference, and activate when identification is needed. This dynamic control resolves the contradiction between maintaining detection capability and avoiding interference.
