Motorcycle Seat Assembly With Fixed Front Section and Adjustable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle seat height adjustment mechanisms often result in inconsistent gaps between the seat and the fuel tank, leading to potential water penetration and a low-quality impression, while existing seat assemblies fail to provide reliable weather protection for underlying components.
Innovation Solution
An adjustable seat assembly with a fixed first section connected to the motorcycle frame and an adjustable second section, utilizing a support element and adjustment device to maintain a consistent gap, ensuring weather protection by allowing height and/or inclination adjustment of the second section relative to the first section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat height is adjusted using conventional adjustment mechanisms, then the seat height is changed to accommodate different riders, but the gap between the seat and fuel tank becomes inconsistent, allowing rainwater penetration and creating a low-quality impression
Solution Approach 1:
The seat pan is divided into a first section (front section without seat surface) and a second section (rear section with seat surface). The first section remains fixed relative to the fuel tank while the second section is adjustable, allowing height adjustment without compromising the weather-sealed gap between the fuel tank and the first section.
Solution Approach 2:
A support element is introduced as an intermediary component between the second section of the seat pan and the motorcycle frame. This support element enables height adjustment of the second section while the first section maintains its fixed, weather-protective position relative to the fuel tank.
2Ease of operation
If the seat height is adjusted using conventional mechanisms, then rider comfort is improved, but the gap between seat and motorcycle components becomes too large, giving a low-quality impression
Solution Approach 1:
By segmenting the seat pan into fixed and adjustable sections, the invention allows the second section to be adjusted for rider comfort while the first section maintains the original aesthetic gap design relative to the fuel tank and motorcycle components.
Solution Approach 2:
Different sections of the seat pan have different functions: the first section maintains fixed aesthetic and weather-protection qualities relative to the fuel tank, while the second section provides adjustable comfort qualities for the rider.
3Adaptability or versatility
If the entire seat pan is made adjustable, then height adaptability is maximized, but the gap consistency and weather protection are compromised
Solution Approach 1:
The seat pan is segmented into a first section that remains fixed to maintain the weather-protective gap with the fuel tank, and a second section that is adjustable for height adaptability. This segmentation allows each section to fulfill its specific function without compromising the other.
Solution Approach 2:
The first section of the seat pan has fixed local quality to maintain weather protection and aesthetic gap consistency, while the second section has adjustable local quality to provide height adaptability for different riders.
