Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional underwater towing test devices are complex, difficult to install, and lack the flexibility to control towing depth and speed effectively, limiting their ability to conduct comprehensive hydrodynamic tests efficiently.
Innovation Solution
The underwater towing test device comprises a driving mechanism, an observation platform, and a towing member with a towing tank, allowing for flexible control of towing depth and speed, and includes a crane for lifting and moving equipment, enabling tests at various depths and speeds, and incorporating a towing member with a cross-joint mechanism for precise positioning and measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional underwater towing test devices are used, then testing capability is provided, but device complexity increases and installation becomes difficult
Solution Approach 1:
The towing test device is divided into independent modular components: a towing vehicle with engine and transmission, a separate trailer with towing rod, and a towed body. Each module can be independently manufactured, tested, and assembled, reducing overall device complexity while maintaining full testing capability.
Solution Approach 2:
The towing vehicle is designed with universal functionality to perform multiple operations: it can tow different types of bodies (submarines, torpedoes, missiles), conduct various tests (hydrodynamic, acoustic, electromagnetic), and operate at different speeds and depths. This multi-functionality eliminates the need for multiple specialized devices.
2Ease of operation
If conventional towing devices are used, then basic towing is achieved, but flexibility in controlling towing depth and speed is limited
Solution Approach 1:
The towing vehicle incorporates dynamic control systems including variable speed propulsion engines and adjustable depth control mechanisms. The transmission system allows continuous speed variation, and the towing depth can be dynamically adjusted during operation, providing full flexibility for comprehensive hydrodynamic testing at various conditions.
3Reliability
If complex conventional devices are used, then testing capability is maintained, but production costs increase
Solution Approach 1:
By segmenting the towing system into standardizable modules (vehicle platform, towing mechanism, test equipment), each component can be manufactured using conventional processes and assembled through standardized interfaces. This modular approach reduces production costs while ensuring reliable testing capability through proven subsystem designs.
