Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If conventional RFID systems are used, then they can be produced at low cost and are small and flexible, but they are difficult to identify or locate under some circumstances
Solution Approach 1:
The patent combines RFID functionality with visual identification elements by integrating an optical element containing embossed indicia with the RFID antenna and chip assembly. This merging allows the device to serve dual purposes: RFID communication and visual identification/locating, thereby resolving the contradiction between ease of detection and device complexity.
Solution Approach 2:
The embossed optical element incorporates retroreflective materials and diffraction patterns that interact with light to create visible indicia. These optical properties enable the RFID device to be easily located and identified visually without adding significant structural complexity, as the visual effects are achieved through material properties rather than additional components.
2Difficulty of detecting and measuring
If embossed optical elements are added to RFID devices, then visibility and identification are improved, but manufacturing complexity increases
Solution Approach 1:
The optical element with embossed indicia is prepared in advance as a separate component before being integrated with the RFID assembly. This preliminary preparation allows the complex embossed features to be manufactured independently using optimized processes, then combined with the RFID components, thereby reducing overall manufacturing complexity while maintaining improved visibility.
Solution Approach 2:
The optical element serves as an intermediary component that bridges the RFID assembly and the visual identification requirements. By introducing this intermediate layer containing embossed and retroreflective features, the patent achieves enhanced visibility without directly modifying the RFID components themselves, simplifying the integration process.
3Adaptability or versatility
If modifying elements are incorporated into RFID devices, then functionality and security are enhanced, but device complexity increases
Solution Approach 1:
The modifying element is designed to perform multiple functions: it can alter the embossed indicia on the optical element based on signals from the RFID chip, provide security features, and enable dynamic information display. This multi-functionality allows a single component to enhance adaptability and security without proportionally increasing device complexity.
Solution Approach 2:
The modifying element introduces dynamic capability to the RFID device by enabling the embossed indicia to change based on received signals. This dynamic behavior allows the device to adapt its visual display according to its state or external commands, enhancing versatility while maintaining a relatively simple structural implementation through the use of thermoplastic material properties.
