Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas and tuning circuits are used to cover multiple frequency bands, then the frequency bandwidth coverage is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a single antenna structure that serves multiple frequency bands (low frequency and medium-high frequency) simultaneously. The antenna includes a low frequency radiation portion and a medium-high frequency radiation portion integrated into one structure, eliminating the need for separate antennas for different frequency bands. This multi-functional design directly resolves the contradiction by achieving wide bandwidth coverage without increasing device complexity
Solution Approach 2:
The patent combines the low frequency antenna and medium-high frequency antenna into a single integrated antenna structure. The low frequency radiation portion and medium-high frequency radiation portion are merged sharing common elements (such as the feeding portion and ground), reducing the overall component count and structural complexity while maintaining coverage across multiple frequency bands
2Adaptability or versatility
If multiple antennas and tuning circuits are used to cover multiple frequency bands, then the frequency bandwidth coverage is improved, but the manufacturing cost increases
Solution Approach 1:
The single multi-functional antenna structure reduces the bill of materials by eliminating redundant components (separate antennas, multiple tuning circuits). The integrated design allows one antenna to perform the function of what would traditionally require multiple separate antenna systems, directly reducing manufacturing cost while maintaining wide frequency bandwidth coverage
Solution Approach 2:
By merging multiple antenna functions into a single integrated structure, the patent reduces the total number of parts that need to be manufactured, assembled, and tested. This consolidation simplifies the manufacturing process and reduces assembly costs, directly addressing the cost increase issue while achieving multi-band coverage
3Volume of moving object
If a simple antenna structure is used in limited configuration space, then the device compactness is improved, but the frequency bandwidth coverage is reduced
Solution Approach 1:
The patent utilizes three-dimensional space efficiently by arranging the low frequency radiation portion and medium-high frequency radiation portion in different spatial dimensions and orientations. The antenna structure extends in multiple directions from a compact central feeding point, achieving wide bandwidth coverage without increasing the overall footprint or volume of the antenna module
Solution Approach 2:
The antenna design nests the medium-high frequency radiation portion within or alongside the low frequency radiation portion structure. The two radiation portions are arranged such that they share common space and structural elements, allowing the antenna to maintain a compact form factor while providing coverage across multiple frequency bands
