Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate wireless antennas are used, then wireless communication function is achieved, but system cost increases and space requirement increases
Solution Approach 1:
The patent combines the antenna function with the chip carrier by making the extension element mechanically connected to and integrally formed with the chip carrier. This merging eliminates the need for separate antenna components, reducing system cost and complexity while maintaining wireless communication functionality through the integrated antenna-structure.
2Reliability
If separate wireless antennas are used, then wireless communication function is achieved, but space requirement on printed circuit board increases
Solution Approach 1:
The antenna is merged with the chip carrier structure, allowing it to be mounted directly on the semiconductor chip without requiring separate mounting space on the printed circuit board. This integration significantly reduces the space requirement while maintaining full wireless communication capability.
3Reliability
If chip carrier is bent out of mounting plane, then antenna configuration is achieved, but manufacturing complexity increases
Solution Approach 1:
The extension element is pre-formed as an integral part of the chip carrier during manufacturing, with the bent configuration already established. This preliminary formation of the antenna structure eliminates the need for complex post-assembly bending operations, reducing manufacturing complexity while achieving the required antenna configuration.
