Integrated Vent Antenna Structure for Space-Saving Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vents for electronic devices do not provide a multifunctional solution that integrates an antenna within the vent structure, requiring separate allocation of space for the antenna within the housing and complicating assembly.
Innovation Solution
A vent with an integrated antenna, such as a PCB antenna, is attached to the inner surface of the body portion, allowing for easy attachment to the housing and connection of the feed cable, while providing an airtight seal and filtration capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If space is allocated within the housing for an antenna, then antenna function is provided, but housing space is consumed and assembly complexity increases
Solution Approach 1:
The patent combines the antenna with the vent structure by attaching the antenna to the inner surface of the vent's body portion. This merging of functions allows the vent to serve dual purposes: ventilation and antenna support, thereby reducing housing space requirements and simplifying assembly procedures.
Solution Approach 2:
The vent structure is designed to perform multiple functions: it provides ventilation through the central vent passage and simultaneously serves as a mounting structure for the antenna. This multi-functionality eliminates the need for separate antenna mounting space and reduces overall device complexity.
2Productivity
If the antenna is attached to the vent, then space utilization is optimized, but the antenna may be vulnerable to damage during transport and mounting
Solution Approach 1:
The antenna is nested within the vent structure by attaching it to the inner surface of the body portion. This nesting provides physical protection for the antenna during transport and installation, while the vent's outer structure acts as a protective shell.
Solution Approach 2:
The vent's body portion structure provides beforehand protection for the attached antenna during transport and mounting operations. The robust outer structure cushions and protects the more vulnerable antenna elements before they are installed in their final position.
3Reliability
If a cover is added to prevent foreign substance entry, then protection is improved, but assembly complexity increases
Solution Approach 1:
The cover is integrated with the vent structure as a unified component rather than a separate attachment. The cover and body portion form a single structural unit that provides both protection and ventilation functions, simplifying the overall assembly.

AI summary
A vent for attachment to a housing wall with an aperture may include a body portion, an attachment mechanism via which the vent is attachable to the housing wall, a cover, and an antenna. The body portion may include a wall with an inner surface defining at least part of a central vent passage via which gas is passable through the vent. The cover may be arranged at a first axial end of the body portion covering the central vent passage. At least one opening may be disposed at a first axial end of the body portion for gas to exit the vent. The antenna may be attached to the inner surface of the wall of the body portion.
