Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless radio signals (Bluetooth, WiFi) are used for audio transmission in aquatic environments, then wireless communication convenience is achieved, but water absorption of radio signals prevents effective audio reception
Solution Approach 1:
The patent introduces a magnetic field as an intermediary medium to transmit audio signals through water. Instead of using radio waves that are absorbed by water, the system converts audio signals into magnetic fields using an induction loop amplifier and transmitting coil, which can penetrate water effectively. The receiving coil in the waterproof audio receiver then converts these magnetic fields back into electrical signals, enabling reliable audio transmission in aquatic environments.
2Device complexity
If traditional wireless audio transmission is used, then simplicity of system is maintained, but audio signal transmission is blocked by water absorption
Solution Approach 1:
The patent replaces the electromagnetic radio wave transmission system with a magnetic field induction system. By using electromagnetic induction principles, the system converts electrical audio signals into magnetic fields that can propagate through water, and then converts them back to electrical signals at the receiver. This substitution of transmission mechanism allows audio signals to pass through water effectively while maintaining reasonable system complexity.
