Antenna Integrated Into Mobile Display Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile display terminals face challenges with separate antennas affecting structural integrity and requiring additional space, leading to design difficulties and potential electromagnetic interference between antennas and PCB wires, which impairs signal reception.
Innovation Solution
The antenna is integrated onto the case of the mobile display terminal and electrically connected to the circuit board via a connector, allowing for reduced internal space usage and minimizing electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the antenna is arranged in a separate manner relative to the mobile display terminal, then the antenna can be easily installed and maintained, but the appearance of the mobile phone will be adversely affected and the structural integrity will be adversely affected
Solution Approach 1:
The antenna is integrated into the case of the mobile display terminal, merging the antenna structure with the case structure. This combination maintains structural integrity while enabling easy installation through modular design, where the antenna can be installed by assembling the case without requiring separate mounting procedures.
2Volume of moving object
If the antenna is integrated into a printed circuit board (PCB) of the mobile display terminal, then the space for the antenna is saved, but two antennae require extremely constrained space and design difficulty increases
Solution Approach 1:
The antenna is arranged on the outer surface or inner surface of the case, utilizing the three-dimensional space of the case structure rather than being constrained to the two-dimensional PCB plane. This dimensional transition provides sufficient space for multiple antennas while simplifying the design process.
3Volume of moving object
If the antenna is integrated into a printed circuit board (PCB) of the mobile display terminal, then the space for the antenna is saved, but electromagnetic interference may occur between the antennae and wires of the PCB, so the reception of the signals may be adversely affected
Solution Approach 1:
The antenna is extracted from the PCB and integrated into the case structure instead. This separation removes the antenna from the electromagnetic environment of the PCB wires, eliminating the source of interference while still achieving compact integration within the terminal device.
