Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatuses, such as portable computers, face interference issues due to noise generated by electronic components affecting the antenna and vice versa, which compromises communication performance.
Innovation Solution
A communication module is positioned within the housing of the portable computer with a conductive holder section surrounding it in all directions except the direction of its directivity, forming a noise insulation wall to reduce interference and maintain communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are placed near the antenna in the housing, then device integration is improved, but noise interference between components and antenna increases
Solution Approach 1:
The housing is divided into a conductive section and a non-conductive section. The conductive section surrounds the antenna element to provide electromagnetic shielding, while the non-conductive section is positioned opposite the element section to allow signal transmission. This segmentation enables both high integration of electronic components and effective noise isolation.
Solution Approach 2:
A holder section is introduced as an intermediary structure between the antenna and other electronic components. This holder section provides physical separation and positioning, preventing direct contact and reducing coupling between the antenna and noise-generating components, thus maintaining both integration and signal quality.
2Strength
If a conductive housing is used, then structural strength is improved, but electromagnetic shielding effectiveness decreases
Solution Approach 1:
Instead of making the entire housing conductive for uniform strength, only specific portions are made conductive. The conductive section is localized around the antenna element to provide electromagnetic shielding where needed, while other portions can be non-conductive or have different material properties optimized for their specific functions.
Solution Approach 2:
The housing employs a composite structure combining conductive and non-conductive sections. This allows the housing to simultaneously provide structural strength through conductive materials in critical areas while maintaining electromagnetic transparency in areas where signal transmission is required.
3Volume of moving object
If the antenna is positioned near the housing wall, then space utilization is improved, but noise from electronic components increases
Solution Approach 1:
The antenna element is nested within the conductive section of the housing, which acts as a protective enclosure. This nested configuration allows the antenna to be positioned close to the housing wall for compact space utilization while the conductive section provides a barrier that isolates the antenna from noise-generating electronic components located elsewhere in the housing.
