Solution Overview
Problem
The challenge in electronic device design is to optimize antenna placement within increasingly smaller internal spaces while maintaining functionality and aesthetics, as devices become thinner and smaller.
Innovation Solution
A housing assembly with a metal frame that includes a bezel portion and a carrying portion, featuring grooves that form an antenna radiator, allowing for efficient RF signal transmission without the need for a separate antenna, thus saving internal space and maintaining a seamless device appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate antenna is installed in the electronic device, then RF signal transmission function is improved, but device internal space is reduced and structure becomes more complex
Solution Approach 1:
The patent merges the antenna function with the existing metal frame structure. The metal arm of the frame is designed to form an antenna radiator, combining structural support and RF signal transmission functions into a single component, thereby eliminating the need for a separate antenna and reducing device complexity
Solution Approach 2:
The metal frame is designed to serve multiple functions: it provides structural support, forms the device housing, and simultaneously acts as an antenna radiator for RF signal transmission. This multi-functionality reduces the number of components needed and simplifies the overall device structure
2Volume of moving object
If device size is reduced to meet miniaturization requirements, then portability is improved, but antenna placement space becomes insufficient
Solution Approach 1:
The antenna function is merged with the metal frame structure, allowing the antenna radiator to be formed within the existing frame geometry. This eliminates the need for additional antenna space and enables miniaturization without compromising antenna functionality
Solution Approach 2:
The patent utilizes the thickness dimension of the metal frame to accommodate the antenna radiator. By designing grooves and recesses in the frame structure, the antenna function is integrated into the three-dimensional space of the existing frame, maximizing space utilization
3Reliability
If metal frame structure is added for antenna function, then RF signal transmission is improved, but manufacturing complexity increases
Solution Approach 1:
The antenna radiator is formed as an integral part of the metal frame structure through grooves and recesses. This merging of functions allows the frame to be manufactured as a single piece or pre-assembled unit, reducing the number of additional manufacturing steps required for separate antenna installation
