Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The formation of multiple slits in metal-bodied mobile terminals compromises appearance design and reduces mechanical rigidity due to segmented metal structures.
Innovation Solution
A mobile terminal design featuring a side case with a single slit, where both end portions are spaced apart to form a single slit, incorporating power feeders and ground portions to function as a radiator for the antenna, with conductive loops enhancing antenna performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slits are formed in the metal case, then antenna functionality is improved, but appearance design is compromised and mechanical rigidity is reduced
Solution Approach 1:
The patent divides the antenna system into multiple independent slits within a single continuous metal case structure. Each slit functions as an independent antenna element, allowing multiple slits to be formed without segmenting the overall metal case, thereby maintaining mechanical rigidity while improving antenna functionality
Solution Approach 2:
The single metal case serves multiple functions: it provides structural support for mechanical rigidity, maintains appearance design integrity, and simultaneously accommodates multiple slits for enhanced antenna functionality. The unified structure eliminates the need for separate structural components
2Adaptability or versatility
If multiple slits are formed in the metal case, then antenna functionality is improved, but appearance design is compromised
Solution Approach 1:
The antenna function is segmented into multiple slits while the metal case remains as a single unified structure. This segmentation of function rather than form allows improved antenna functionality without compromising the continuous, clean appearance of the metal case exterior

Function Achieved in This Case
Improves mechanical rigidity and allows for easy bending of the metal case while utilizing the side case as an antenna radiator, enhancing antenna functionality.
Implementation Method 1
a side case made of a metal material, and integrally formed to form a side appearance of the terminal body, both end portions of which are spaced apart to face each other to form a single slit
Implementation Method 2
a first conductive loop is formed on a path along the side case, the single slit, and the conductive member from the second power feeder, and a second conductive loop is formed on a path along the conductive member through the side case from the first power feeder
