Waterproof Camera Antenna Positioning for Floating Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waterproof camera systems face challenges in maintaining a wireless connection with external devices while floating on the water surface due to the inability of radio waves to propagate underwater, particularly when the system is designed for both underwater and above-water image pickup.
Innovation Solution
A waterproof camera system with a wireless module and a float-equipped casing, where the antenna unit is positioned either at the water surface level or slightly above, ensuring stable wireless communication during both underwater and above-water image pickup operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna unit is positioned inside the waterproof casing for underwater image pickup, then the image pickup capability is improved, but the wireless connection reliability deteriorates due to radio wave inability to propagate underwater
Solution Approach 1:
The patent applies local quality by positioning the antenna unit at a specific location (water surface level or above) rather than uniformly inside the casing, creating a localized wireless communication zone that maintains connection reliability while the rest of the system remains waterproof for image pickup
Solution Approach 2:
The patent transitions the antenna unit from a two-dimensional position inside the waterproof casing to a three-dimensional position at or above the water surface, allowing radio waves to propagate in air while the image pickup apparatus remains underwater or at the water surface
2Reliability
If the antenna unit is positioned above the water surface for wireless communication, then the wireless connection reliability is improved, but the image pickup versatility deteriorates when the system needs to float in different positions
Solution Approach 1:
The patent makes the antenna unit's position dynamic relative to the water surface by allowing it to be positioned at water surface level or above, adapting to different floating positions and image pickup requirements while maintaining wireless connection reliability
Solution Approach 2:
The antenna unit design achieves multi-functionality by serving both wireless communication purposes (maintaining reliable connection when floating) and image pickup purposes (supporting both underwater and above-water operations through strategic positioning)
3Ease of operation
If the waterproof casing is designed to float stably on the water surface, then the ease of operation is improved, but the antenna unit positioning complexity increases to maintain wireless connection
Solution Approach 1:
The patent merges the antenna unit positioning with the floating structure design, integrating the antenna into the waterproof casing's floating mechanism rather than treating them as separate components, thereby reducing overall system complexity

AI summary
A waterproof camera system that maintains a wireless connection state with an external device while floating on a water surface includes an image pickup apparatus equipped with a wireless module, a waterproof casing that hermetically stores the image pickup apparatus, and a float attached to the waterproof casing. An antenna unit of the wireless module is arranged at either a position with a height approximately equal to a water surface or a position separated from the water surface in an above water direction in each of a first position where the waterproof camera system floats on the water surface so that the image pickup apparatus can perform underwater image pickup and a second position where the waterproof camera system floats on the water surface so that the image pickup apparatus can perform above water image pickup.
