Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of maintaining antenna performance while ensuring sufficient mounting space and aesthetics in electronic devices with limited slits in the housing, which can impair stiffness and restrict frequency band services.
Innovation Solution
Incorporating a housing design with a first and second conductive member separated by a slit, a support member, and a connection part protruding inward from the slit to serve as a radiator, connected via a coupling member to a PCB, enhancing antenna performance and enabling carrier aggregation without compromising space or aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of slits in the housing is increased to provide more radiators for multi-frequency band services, then the antenna performance and frequency band coverage are improved, but the aesthetics of the electronic device are impaired and the stiffness of the housing is reduced
Solution Approach 1:
The housing is segmented into multiple conductive members (first conductive member, second conductive member, third conductive member) separated by slits. Each conductive member functions as an independent radiator for different frequency bands, enabling multi-frequency operation while maintaining housing integrity and aesthetics through controlled segmentation rather than numerous slits
Solution Approach 2:
Each conductive member serves multiple functions: it acts as both a structural component of the housing and a radiator for wireless communication. The first conductive member radiates in a first frequency band, the second conductive member radiates in a second frequency band, and the third conductive member radiates in a third frequency band, allowing the housing to provide universal communication services across multiple bands without adding more slits
2Area of stationary object
If the number of slits in the housing is increased to accommodate more antenna modules, then the mounting space for antennas is improved, but the aesthetics of the electronic device are impaired
Solution Approach 1:
The housing structure itself is designed to serve as the antenna module, eliminating the need for separate antenna components that would require additional mounting space and slits. The conductive members integrated into the housing perform both structural and radiating functions, providing adequate antenna functionality without compromising housing aesthetics
Solution Approach 2:
The antenna function is merged with the housing structure. The first conductive member, second conductive member, and third conductive member are integral parts of the housing that simultaneously provide mechanical support and electromagnetic radiation, combining structural and functional elements into a unified design
