Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders on vehicles, such as motorcycles, face comfort issues due to varying shapes and sizes, and there is a need for adjustable seat back support systems that can accommodate different preferences for seat back height and position.
Innovation Solution
A seat back support assembly that includes a vehicle engaging member and a seat back receiving member, allowing for adjustable positioning in multiple vertical and horizontal positions, with optional angular adjustment, to securely attach a seat back to a vehicle seat, accommodating various rider preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat back is installed on the vehicle seat, then the structure is simple and easy to manufacture, but it cannot accommodate riders of various shapes and sizes, reducing comfort and adaptability
Solution Approach 1:
The seat back support assembly is divided into multiple adjustable components including the seat back receiving member, base, vertical support members, and horizontal support members. Each segment can be independently positioned to achieve different configurations, allowing adaptation to various rider preferences while maintaining a modular structure that doesn't excessively increase complexity.
Solution Approach 2:
The assembly transitions from a fixed structure to a dynamic, adjustable system. The base can be repositioned along the vertical support member, and the horizontal support member can be adjusted along the vertical axis, enabling the seat back to adapt to different rider heights and preferences. This dynamic capability directly addresses the adaptability requirement.
2Adaptability or versatility
If a seat back is included for all riders, then coverage is complete, but it increases device complexity and cost for riders who do not need it
Solution Approach 1:
The seat back support assembly is designed as a universal system that can accommodate both riders who want a seat back and those who prefer no seat back. The adjustable components allow the same assembly to serve multiple functions: providing full seat back support when needed, or being configured to provide minimal support for riders who prefer an open seating position, eliminating the need for different assemblies for different rider preferences.
3Ease of operation
If the seat back is fixed at a single height, then the structure is simple, but it cannot provide comfort for riders of different heights
Solution Approach 1:
The vertical support member acts as an intermediary element between the base and the seat back receiving member. It provides a structured pathway for adjustment, allowing the base to be repositioned to different heights along its length. This intermediary component enables height adjustment without requiring complex mechanisms, as the vertical support member itself serves as the adjustment guide and structural connector.

AI summary
A seat back support assembly comprises a vehicle engaging member and a seat back receiving member. The vehicle engaging member is configured to be secured to a vehicle body. The vehicle engaging member includes a supporting section. The seat back receiving member includes (i) a base that is adjustably coupled to the supporting section, and (ii) a receiver that is coupled to the base, the receiver being configured to receive the seat back. The base is alternately positioned in a first vertical position and a second vertical position relative to the supporting section. When the base is in the first vertical position, the seat back is at a first height relative to the vehicle seat. Alternatively, when the base is in the second vertical position, the seat back is at a second height relative to the vehicle seat that is different than the first height.
