Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radiators and substrates are used for multi-band antenna, then communication coverage is improved, but device size and manufacturing cost increase
Solution Approach 1:
The patent combines multiple radiators for different frequency bands (LTE and 5G) onto a single substrate, eliminating the need for separate substrates for each band. This integration reduces the overall device volume while maintaining multi-band communication capabilities through shared structural support and ground plane.
Solution Approach 2:
The single substrate serves multiple functions by supporting both LTE and 5G radiators simultaneously, acting as a universal platform for multi-band operations. This multi-functional approach allows one substrate to replace what would traditionally require multiple specialized substrates, reducing device size.
2Adaptability or versatility
If multiple radiators and substrates are used for multi-band antenna, then communication coverage is improved, but manufacturing cost increases
Solution Approach 1:
By merging multiple radiators onto a single substrate, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation decreases manufacturing complexity, reduces material costs, and simplifies the production process while still achieving multi-band communication coverage.
Solution Approach 2:
The universal substrate design that supports multiple frequency bands reduces the need for multiple specialized components, thereby lowering overall manufacturing costs through economies of scale and reduced assembly operations.
3Reliability
If connector module protrudes from antenna, then electrical connection is achieved, but installation space requirement increases
Solution Approach 1:
The connector module is nested within the housing structure of the antenna rather than protruding externally. This nesting approach allows the electrical connection interface to be contained within the overall antenna volume, eliminating the need for additional installation space while maintaining reliable electrical connectivity.
