Rotating Third Housing Antenna Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in efficiently integrating antennas for wireless communication due to interference from display panels and circuit boards, requiring additional radio wave shielding that increases size and complexity.
Innovation Solution
The electronic apparatus incorporates a third housing with a biaxial hinge mechanism between the main housings, allowing the antenna to be mounted in a separate compartment that rotates relative to the display and circuit boards, maintaining a significant distance and reducing interference, thus minimizing the need for shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna is mounted close to the display panel and circuit board to reduce device size, then the device compactness is improved, but the antenna performance deteriorates due to radio wave interference
Solution Approach 1:
The device is divided into multiple housing sections: a first housing containing the display panel, a second housing containing the circuit board, and a third housing containing the antenna. This segmentation physically separates the antenna from interfering components while maintaining overall device compactness.
Solution Approach 2:
The antenna is positioned in a third dimension by introducing a third housing that extends in a direction different from the display panel and circuit board arrangement. The biaxial hinge mechanism enables rotation in multiple axes, creating spatial separation without increasing the device's footprint in the primary plane.
2Reliability
If radio wave shielding is added to protect the antenna from interference, then the antenna performance is improved, but the device complexity and size increase
Solution Approach 1:
The antenna is extracted from the common housing structure and placed in a separate third housing. This extraction eliminates the need for complex shielding structures within the main housing, as the antenna is naturally isolated by its separate compartment.
Solution Approach 2:
The third housing acts as an intermediary structure between the display panel and circuit board on one side, and the antenna on the other. This intermediate housing provides natural isolation without requiring additional shielding materials or complex electromagnetic interference protection structures.
3Object-affected harmful factors
If the antenna is placed in a separate rotatable housing, then the interference from display and circuit board is reduced, but the device structure becomes more complex
Solution Approach 1:
The third housing serves multiple functions: it contains the antenna, provides isolation from interfering components, and enables rotational adjustment via the biaxial hinge mechanism. This multi-functionality reduces the need for additional separate components for each function.
Solution Approach 2:
The biaxial hinge mechanism enables the third housing to rotate dynamically, allowing the antenna to be positioned at different angles and orientations. This dynamic capability provides flexibility in optimizing antenna performance for different usage scenarios without requiring multiple fixed antenna structures.
