Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sonar systems face challenges in transmitting sonar pings from multiple transducer elements simultaneously due to interference issues, which limits the ability to use multiple transducers concurrently.
Innovation Solution
The implementation of a synchronization wire connected to multiple sonar modules allows for synchronized transmission of sonar pings, reducing interference by ensuring that all modules are ready before transmitting simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sonar transducers transmit sonar pings simultaneously, then sonar coverage and image quality are improved, but ping interference between transmitted sonar pings increases
Solution Approach 1:
The system performs preliminary readiness checks and synchronization voltage assessments before allowing simultaneous transmission. Each sonar module evaluates its readiness state and communicates via synchronization wire to ensure all modules are prepared before transmitting pings together, preventing interference caused by unsynchronized transmissions
Solution Approach 2:
The synchronization wire carries feedback signals between sonar modules, allowing each module to detect the readiness status of others. This feedback mechanism enables dynamic coordination where transmission timing is adjusted based on real-time status of all modules, reducing ping interference while maintaining simultaneous operation
2Measurement precision
If a synchronization wire with independent processing circuitry is used to coordinate multiple sonar modules, then synchronization precision is improved, but device complexity increases
Solution Approach 1:
Each sonar module independently determines its own transmission timing by evaluating the synchronization voltage from its peers through the synchronization wire. The modules self-coordinate without requiring an external controller or complex centralized processing circuitry, reducing overall system complexity while maintaining synchronization precision
Solution Approach 2:
The synchronization wire serves multiple functions: it carries readiness status signals, transmission timing information, and coordination data between all sonar modules. This multi-functional approach eliminates the need for separate dedicated circuits for each function, reducing device complexity while achieving precise synchronization
3Loss of information
If multiple sonar modules are added to the system to improve coverage, then sonar information quality is improved, but ease of installation deteriorates
Solution Approach 1:
The sonar system is divided into independent, modular units that can be individually installed and configured. Each module operates autonomously but connects through the standardized synchronization wire interface, allowing incremental installation without requiring complete system reconfiguration or complex integration work

AI summary
A synchronization wire for synchronizing sonar ping transmissions from sonar transducer elements or arrays is provided. The synchronization wire includes first and second connection points. The first connection point is configured to connect the synchronization wire to a first sonar module that is configured to control transmission of a first sonar ping from a first sonar transducer. The second connection point is configured to connect the synchronization wire to a second sonar module that is configured to control transmission of a second sonar ping from a second sonar transducer. The synchronization wire is configured to transfer an electrical current between the first and second sonar modules. The synchronization wire is configured to enable synchronization of the first and second sonar modules through the use of the electrical current. Processing circuitry in sonar modules may cause or prevent transmission of sonar pings based on the voltage level on the synchronization wire.
