Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design an electronic device that can efficiently support multiple frequency bands in the mmWave band while maintaining a compact form factor, as the high directivity of mmWave signals requires multiple communication devices for omnidirectional radiation, which can occupy valuable space in the device's housing.
Innovation Solution
The electronic device incorporates a housing with a specific antenna structure that includes multiple planar structures with conductive plates, allowing for the use of different antenna elements to transmit and receive signals in various frequency bands, optimizing space usage by radiating signals towards multiple planes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication devices are used for omnidirectional radiation in mmWave band, then coverage is improved, but device volume increases
Solution Approach 1:
The patent combines multiple antenna elements (first and second antenna elements) into a single communication device structure. The antenna elements are positioned at different orientations within the same device housing, allowing omnidirectional radiation coverage to be achieved while maintaining a compact form factor. This merging approach resolves the contradiction by integrating multiple radiation functions into one device rather than using separate communication devices.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning antenna elements at different orientations and locations within the device housing. The first antenna element is positioned to radiate in a first direction while the second antenna element radiates in a second direction, creating omnidirectional coverage through spatial distribution. This dimensional approach allows coverage improvement without proportionally increasing device volume.
2Reliability
If multiple antenna elements are positioned at different orientations, then omnidirectional radiation is achieved, but device complexity increases
Solution Approach 1:
The communication device is designed with multi-functionality by incorporating antenna elements that can serve different radiation purposes within a single device. The first and second antenna elements can be selectively activated based on communication requirements, allowing the device to function as both a compact unit and an omnidirectional radiator. This universal design reduces complexity compared to having separate specialized devices.
