Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adhesive application and RFID circuit element placement are performed on-site during manufacturing, then manufacturing precision can be achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The adhesive layers are pre-applied to the first and second tapes before the RFID circuit elements are attached. This preliminary action eliminates the need for on-site adhesive application equipment and simplifies the manufacturing process while maintaining positioning precision through the pre-prepared adhesive layers.
Solution Approach 2:
The manufacturing process is segmented into separate stages: first tape preparation with adhesive layer, RFID circuit element attachment, second tape preparation with adhesive layer, and final bonding. This segmentation allows each component to be prepared independently with optimized processes, reducing overall system complexity.
2Manufacturing precision
If high-precision control is used for RFID circuit element placement, then manufacturing precision improves, but device complexity and cost increase
Solution Approach 1:
The RFID circuit elements are attached to the first tape at predetermined intervals before the second tape is bonded. This preliminary attachment establishes fixed positioning without requiring complex real-time control during the final bonding process, as the elements are already in their predetermined positions.
Solution Approach 2:
The first and second tapes with adhesive layers self-align and bond together, automatically positioning the RFID circuit elements between the adhesive layers. This self-alignment mechanism eliminates the need for complex external control systems to maintain placement precision.
3Productivity
If adhesive application and RFID element attachment are performed simultaneously, then manufacturing speed increases, but manufacturing precision decreases
Solution Approach 1:
The manufacturing process is divided into sequential steps: first tape with adhesive layer is prepared, then RFID circuit elements are attached to the first tape, then the second tape with adhesive layer is prepared and bonded. This segmentation allows adhesive application and element attachment to occur at different stages, maintaining both speed and precision.
Solution Approach 2:
RFID circuit elements are attached to the first tape before the second tape is bonded to them. This preliminary attachment ensures precise positioning is established before the final bonding step, preventing positioning errors that would occur if both operations were performed simultaneously.
4Ease of manufacture
If RFID tag characteristic values are not considered, then manufacturing process is simpler, but communication precision deteriorates
Solution Approach 1:
The system reads RFID tag characteristic values (such as sensitivity) and uses this feedback information to adjust communication parameters. This feedback mechanism ensures optimal communication precision by adapting to the actual characteristics of each RFID tag while maintaining a relatively simple manufacturing process.
Solution Approach 2:
Communication parameters such as transmission power and frequency are dynamically adjusted based on the read characteristic values of the RFID tags. This parameter adaptation enables precise communication without complicating the manufacturing process, as the adjustment occurs during operation rather than production.
