Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face challenges in achieving a compact design while maintaining excellent communication states, particularly due to interference from metallic components that can disturb radio wave transmission and reception.
Innovation Solution
The design incorporates antenna elements accommodated within depression sections of the base housing, positioned to avoid interference with hinges and metallic structural elements, using covers that allow radio wave passage and maintaining adequate distances to minimize communication disturbances, allowing for a downsized and easily configured notebook-sized personal computer with improved communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna elements are accommodated within depression sections of the base housing, then communication performance is improved by avoiding interference from metallic components, but device complexity increases due to the need for specialized housing structures
Solution Approach 1:
The base housing is segmented into depression sections that specifically accommodate antenna elements, separating the antenna housing space from other components. This segmentation allows the antenna to be positioned away from interfering metallic structures while maintaining an integrated housing design.
Solution Approach 2:
The housing structure is designed with localized depression sections only where antenna elements need to be accommodated, rather than redesigning the entire housing. This local modification minimizes structural complexity while achieving the communication performance improvement.
2Reliability
If adequate distance is maintained between antenna elements and metallic structural elements, then communication disturbances are reduced, but device volume increases
Solution Approach 1:
The depression sections utilize the thickness dimension of the base housing to create separation between antenna elements and interfering metallic structures. By exploiting the Z-axis (thickness direction) rather than only planar dimensions, adequate distance is achieved without increasing the device's footprint area.
3Reliability
If covers allowing radio wave passage are used, then antenna performance is improved, but manufacturing complexity increases
Solution Approach 1:
The covers are designed with uniform radio wave permeable properties across their surface, using homogeneous material composition or consistent structural patterns that allow radio waves to pass through while maintaining standard manufacturing processes for cover production.
