Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool sound systems require wired connections, which are inefficient and unreliable when submerged in water due to interference from the aquatic environment.
Innovation Solution
A pool sound system with electroacoustic transducers and a control unit featuring a radio-frequency communication module, such as Bluetooth or WiFi, with an antenna positioned above the waterline to enable reliable and energy-efficient wireless audio transmission, allowing the system to operate independently without being wired to a sound source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used for pool sound systems, then audio signals can be transmitted to the sound system, but the connection becomes unreliable and inefficient when submerged in water due to interference from the aquatic environment
Solution Approach 1:
The patent extracts the antenna and wireless communication module from the submerged aquatic environment and positions them above the waterline. This separation removes the harmful water interference from the wireless communication path while maintaining audio transmission capability to underwater transducers through the water-resistant sealed housing design.
2Ease of operation
If wired connections are used for pool sound systems, then audio signals can be transmitted, but the system requires complex wiring infrastructure that reduces ease of operation
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system using radio-frequency modules and antennas. This substitution eliminates the need for physical wiring infrastructure, making the system easier to install and operate while maintaining reliable audio signal transmission to the sound system.
3Adaptability or versatility
If antennas are positioned below waterline for wireless communication, then wireless connection can be provided, but the connection becomes affected by surrounding water reducing reliability
Solution Approach 1:
The patent applies different spatial positioning strategies to different components: the antenna is positioned above the waterline in the air-exposed portion of the housing to ensure reliable wireless communication, while the electroacoustic transducers are positioned below the waterline in the aquatic environment to provide sound in the pool. This local quality differentiation optimizes each component's performance in its appropriate environment.
