Camera Internal Antenna Layout via Non-Metallic Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices with internal antennas face challenges in achieving optimal electromagnetic wave gain and efficient internal layout due to the need for non-metallic surfaces for antenna radiation, leading to complex production processes and aesthetic issues such as parting lines and inefficient space usage.
Innovation Solution
The camera device features a metal body with a non-metallic injection grip portion housing antennas on one side, allowing for enhanced antenna gain by positioning them according to radiation direction and frequency bands, reducing parting lines, and optimizing internal layout by minimizing antenna interference with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire upper surface and lower surface are covered with injection molding material to maximize antenna gain, then antenna radiation performance is improved, but production time increases and a parting line occurs between metal and injection molding material
Solution Approach 1:
The patent applies local quality by covering only specific areas (upper surface and lower surface) with injection molding material rather than the entire camera body. This localized approach provides sufficient non-conductive space for antenna radiation in critical areas while reducing the total amount of injection molding required, thereby shortening production time and reducing the visibility of parting lines.
2Adaptability or versatility
If antennas are distributed in several areas within the camera device, then communication functions are enhanced, but efficiency of internal layout deteriorates and device size increases
Solution Approach 1:
The patent merges multiple antenna functions into a consolidated layout within the camera body. By strategically positioning GPS, Wi-Fi, and other communication antennas in optimized locations with proper spacing, the design achieves full communication functionality without requiring distributed antennas across the entire device, thereby maintaining compact size and efficient internal layout.
3Reliability
If antennas are positioned near metal parts to maximize gain, then antenna performance is improved, but electromagnetic wave radiation is shielded by metal
Solution Approach 1:
The patent introduces injection molding material as an intermediary substance between the metal camera body and the antennas. This non-conductive material acts as a mediator that allows antennas to be positioned close to the metal structure for compact design while preventing electromagnetic wave shielding, thereby maintaining high antenna gain without the harmful effects of metal interference.

AI summary
A camera (20) having an internal antenna includes a metal body portion (23) forming an external surface of the camera, excluding one side surface (22). A non-metallic injection grip portion (23) comprises the one side surface (22) and is fastened to the metal body portion (23). An antenna portion (24) having at least one radiator (A1) is disposed within the injection grip portion (22). The configuration can allow for a more efficient arrangement of radiators (A1, A2) and other components, reduce interference between the antenna (24) and metal components of the camera (20), and can exhibit an aesthetic appearance.
