Convertible Towable Inflatable Device With Adjustable Backrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Towable inflatable devices for watercraft typically allow only a single riding position, leading to rider fatigue and boredom due to prolonged use in a single position, which can be unsafe if the rider changes positions.
Innovation Solution
A towable inflatable device designed with interchangeable configurations allowing a rider to switch between seated and prone positions, featuring lateral supports and a backrest that can be adjusted between upright and horizontal orientations, maintaining hydrodynamic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the towable inflatable device is configured for a single riding position, then the device structure is simple and aerodynamic, but the rider experiences fatigue and boredom from prolonged use in a single position
Solution Approach 1:
The backrest is designed as a movable component that can be adjusted between an upright position (for seated riding) and a lowered position (for prone riding). This dynamic adjustment allows the device to adapt to different riding configurations without requiring multiple separate devices, resolving the contradiction between versatility and structural simplicity
Solution Approach 2:
The single towable inflatable device is designed to perform multiple functions by accommodating both seated and prone riding positions through the adjustable backrest mechanism. This multi-functionality eliminates the need for separate devices for different riding styles, maintaining structural simplicity while providing adaptability
2Reliability
If the rider remains in a single position for extended periods, then the device structure remains simple, but the rider becomes fatigued and may adopt unsafe positions
Solution Approach 1:
The adjustable backrest provides a safe and secure transition mechanism for riders to change positions during towing. By providing a controlled way to switch between seated and prone positions, the device maintains reliability and safety without requiring complex additional safety systems
Solution Approach 2:
The backrest angle parameter can be changed between two primary states (upright and lowered) to accommodate different riding positions. This parameter change allows safe position transitions while keeping the adjustment mechanism relatively simple
3Adaptability or versatility
If the backrest is positioned upright for seated configuration, then lateral support is provided for seated riders, but the device cannot accommodate prone lying position
Solution Approach 1:
The backrest is designed with movable interconnection that allows straightforward transition between upright and lowered positions. This dynamic design makes position switching easy to operate while providing both seated and prone configurations, resolving the contradiction between adaptability and ease of operation
