Inflatable Boat Rudder Assembly Bolt Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rudder assemblies for inflating boats require deflation of the boat to detach the rudder board from the securing base, making storage and carrying inconvenient due to the need for deformation of the securing base, which is not easily achievable while the boat is inflated.
Innovation Solution
A rudder assembly featuring a securing base with a base board, board mount, holding recess, engaging bracket, and through hole, and a rudder board with rudder hooks and engaging bolts, allowing for secure attachment and easy detachment without the need for deflation, using a male and female element mechanism to screw and unscrew for mounting and dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hooks are used to engage the rudder board to the securing base, then the rudder board can be detached, but the securing base cannot be deformed while the boat is inflated making detachment impossible
Solution Approach 1:
The patent replaces the hook-based mechanical engagement system with a bolt-based fastening system. The engaging bolt passes through the securing base and threads into the rudder board, creating a rigid mechanical connection that does not require deformation of the securing base for attachment or detachment. This substitution resolves the contradiction by enabling easy detachment while maintaining the structural integrity and rigidity of the securing base during inflation.
2Ease of operation
If the boat is deflated to detach the rudder board, then the securing base can be deformed for detachment, but this causes inconvenience for storage and carrying
Solution Approach 1:
The bolt-based fastening system eliminates the need for deflation/inflation cycles to attach or detach the rudder board. The engaging bolt can be simply unscrewed and removed from the securing base, allowing immediate detachment regardless of the boat's inflation state. This mechanical substitution saves the time that would otherwise be spent on deflating and inflating the boat.
3Ease of operation
If the securing base is made deformable to allow detachment, then the rudder board can be removed easily, but the securing base cannot be easily deformed when the boat is inflated
Solution Approach 1:
The patent replaces the deformation-based detachment mechanism with a bolt-based fastening system. The engaging bolt provides a secure mechanical connection that maintains the structural integrity of the securing base while allowing easy attachment and detachment through simple bolting and unbolting operations. No deformation of the securing base is required, preserving its strength and rigidity.

AI summary
A rudder assembly for a boat has a securing base, a rudder board and at least one engaging bolt. The rudder board is mounted detachably on the securing base and has a bottom and two rudder hooks. The rudder hooks are formed respectively on two ends of the bottom and are connected securely to the securing base with the at least one engaging bolt. The at least one engaging bolt is mounted detachably on the securing base and engages respectively at least one of the rudder hooks on the rudder board. Accordingly, a rudder board can be conveniently detached from the securing base even while an inflating boat is at an inflated condition.
