Boat Interceptor Guiding Arrangement for Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrangements for dynamic control of a boat's running trim and list are prone to malfunction and damage due to external forces, leading to decreased performance and shortened lifespan, necessitating a more robust and reliable solution.
Innovation Solution
The introduction of a guiding arrangement with a base body and toothed wheels between the interceptor member and the housing, which absorbs forces and distributes them evenly, preventing bending or displacement of the interceptor, and allowing for flexible adaptation and low-friction movement through roller members and separate toothed surfaces for interaction with the housing and interceptor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an interceptor member is used to increase water pressure on the bottom of the hull during operation, then the running trim of the boat is changed, but the arrangement is prone to malfunction and damage due to the force of the water acting on the interceptor member
Solution Approach 1:
A guiding arrangement is introduced as an intermediary component between the interceptor member and the housing. This guiding arrangement includes a base body with rolling members that interact with toothed wheels, which in turn interact with toothed surfaces on the interceptor member and housing. The guiding arrangement mediates the forces between water and the interceptor, distributing loads and preventing direct transmission of damaging forces to the interceptor member, thereby resolving the contradiction between maintaining trim control performance and improving reliability.
2Device complexity
If the interceptor member is directly connected to the housing, then the structure is simpler, but the interceptor member bends or displaces under water forces
Solution Approach 1:
The guiding arrangement serves as an intermediary mechanism between the interceptor member and housing, incorporating a base body with rolling members and toothed wheels. This intermediate structure prevents direct rigid connection while maintaining positional stability by distributing forces through the rolling and toothed interaction mechanism, thereby preventing bending or displacement of the interceptor member.
Solution Approach 2:
The direct mechanical connection between interceptor and housing is replaced with a guided mechanical interaction system. The toothed wheels interacting with toothed surfaces replace the need for rigid direct connection, while the rolling members substitute for traditional bearing connections. This substitution maintains stability while reducing structural complexity through modular, replaceable components.
3Reliability
If the guiding arrangement uses a base body with rolling members and toothed wheels, then forces are distributed evenly and reliability is improved, but the device complexity increases
Solution Approach 1:
The guiding arrangement is segmented into distinct functional components: a base body with rolling members for force distribution, toothed wheels for guided movement, and toothed surfaces for interaction with the interceptor and housing. This segmentation allows each component to perform its specific function efficiently while maintaining overall reliability, and the modular nature facilitates easier maintenance and replacement despite the increased complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the reliability and longevity of the arrangement by minimizing the risk of malfunction and damage, ensuring uniform force distribution and reducing maintenance needs, while maintaining high hydrodynamic lift with low drag.
Implementation Method 1
By also allowing a base body of the guiding arrangement to act as a roll between the interceptor member and the housing, the forces applied can be divided equally over the entire length of the arrangement
Implementation Method 2
providing toothed surfaces for interaction with the guiding arrangement in an inner surface of the housing as well as on a surface of the interceptor member, to enable a toothed interaction of the guiding arrangement with the interceptor as well as with the housing
Implementation Method 3
provide roller members placed on the other side of the interceptor from the point of view of the guiding member, to provide for a low friction movement of the interceptor in relation to the housing
