Adjustable Straddle Seat Mounting for Personal Watercraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal watercraft seats lack adjustability to accommodate users with different physical characteristics, leading to inconsistent ride comfort.
Innovation Solution
Incorporating a mounting adjuster system that allows the straddle seat to be positioned in multiple locations along the front-rear direction, enabling customizable seating based on user preferences and physical characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat position is used on the watercraft body, then the device complexity is reduced, but the adaptability to different users' physical characteristics deteriorates
Solution Approach 1:
The seat mounting system transitions from a fixed position to a dynamically adjustable position along the front-rear direction. The mounting adjuster enables the seat to be repositioned to multiple mounting positions, allowing adaptation to different users' physical characteristics while maintaining a relatively simple mechanical structure through telescopic adjustment mechanisms.
2Adaptability or versatility
If a single fixed seat is provided, then the manufacturing cost is reduced, but the ability to accommodate different user preferences deteriorates
Solution Approach 1:
A single seat assembly is designed to perform multiple functions by incorporating a mounting adjuster that enables position adjustment along the front-rear direction. This universal seat can serve different users with varying physical characteristics and preferences, eliminating the need for multiple fixed seats while maintaining manufacturing efficiency through a standardized adjustable mounting system.
