Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing thin and light foldable electronic devices with maximized System-on-a-Chip (SoC) performance is challenging, especially when thermal solutions extend from one section to another, as the arrangement of antennas near thermal cross spread sheets can interfere with their performance.
Innovation Solution
Integrating antennas into openings or surfaces of thermal cross spread sheets, such as graphite, and using flexible printed circuit antennas with strategic positioning to minimize interference, along with dual antennas on opposing sides of supporting structures to enhance radiation coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If antennas are placed near thermal cross spread sheets for compact design, then space consumption is reduced, but antenna performance deteriorates due to interference
Solution Approach 1:
The patent extracts the antenna from the conventional placement near thermal cross spread sheets and repositions it on the surface of the thermal cross spread sheet itself. This separation eliminates the interference between the antenna and surrounding structures while maintaining compact overall device design. The antenna is integrated into the thermal management structure rather than being placed adjacent to it.
Solution Approach 2:
The patent combines the antenna structure with the thermal cross spread sheet by placing the antenna directly on its surface. This merging allows the thermal cross spread sheet to serve dual purposes: thermal management and antenna support, thereby reducing overall space consumption while maintaining antenna performance through strategic positioning.
2Adaptability or versatility
If dual antennas are placed on opposing sides of supporting structures to enhance radiation coverage, then radiation coverage is improved, but device complexity increases
Solution Approach 1:
The patent makes the supporting structure universal by enabling it to serve multiple functions: structural support, antenna mounting platform, and radiation enhancement element. By placing antennas on opposing sides of the same supporting structure, the system achieves enhanced radiation coverage without adding separate complex antenna support structures for each antenna.
3Temperature
If thermal solutions are extended from one section to another for improved cooling, then cooling effectiveness is improved, but antenna performance deteriorates due to interference with thermal cross spread sheets
Solution Approach 1:
The patent introduces the thermal cross spread sheet surface as an intermediary platform that mediates between the thermal management requirement and antenna performance. The antenna is placed on this intermediary surface, allowing thermal solutions to be extended across the device while the antenna maintains optimal performance through its specific positioning on the thermal cross spread sheet.
