Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate antennas are mounted in the terminal, then dual antenna functionality is achieved, but the space required and manufacturing cost increase
Solution Approach 1:
The patent combines two separate antennas into a single integrated antenna structure that operates at two different frequencies. The antenna includes a first antenna element for a first frequency and a second antenna element for a second frequency, both integrated within one antenna assembly. This merging eliminates the need for two separate antenna mounts, reducing the space required while maintaining dual antenna functionality for different frequency bands
Solution Approach 2:
The integrated antenna is designed to perform multiple functions by operating across different frequency bands. The single antenna structure can simultaneously or alternatively operate at a first frequency and a second frequency, making it a universal antenna solution that replaces multiple single-frequency antennas. This multi-functionality reduces both the number of antenna components and the space required for their installation

3Object-affected harmful factors
If a shield case is added to protect electronic elements from electromagnetic waves, then electromagnetic shielding is achieved, but the device complexity increases
Solution Approach 1:
The shield case is integrated with the antenna structure, combining the shielding function and the antenna function into a single component. The shield case includes a first portion and a second portion that form both the protective enclosure and the antenna elements. This integration eliminates the need for separate shielding components and separate antenna components, reducing device complexity while maintaining both electromagnetic shielding and antenna functionality
Solution Approach 2:
The shield case is designed to perform multiple functions: it provides electromagnetic shielding for electronic elements and simultaneously serves as the antenna structure for wireless communication. The conductive material forming the shield case also forms the antenna elements, making the shield case a multi-functional component that replaces both the shielding enclosure and the antenna assembly
