Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycles face limitations in mechanical rigidity/mass ratio, aerodynamics, and component arrangement due to the presence of a traditional frame, which increases design complexity and costs while affecting thermal management and component placement.
Innovation Solution
A motorcycle design that eliminates the traditional frame by using a box-like body made of lightweight materials to support the engine and other components, incorporating a box-like body that functions as both an airbox and structural support, optimizing air flow and thermal exchange, and allowing for improved component arrangement and rationalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional frame is used to support the engine and components, then mechanical strength and structural stability are ensured, but the rigidity/mass ratio deteriorates and design freedom is limited
Solution Approach 1:
The patent merges the frame structure with the airbox into a single integrated component. The airbox serves dual functions: as an air intake reservoir and as part of the vehicle's structural frame, eliminating the need for a separate traditional frame while maintaining both aerodynamic and structural requirements
Solution Approach 2:
The airbox is designed to perform multiple functions simultaneously: it serves as an air intake system component, provides structural support as a frame element, and contributes to the vehicle's aerodynamics. This multi-functionality reduces overall vehicle mass while maintaining necessary structural strength
2Stability of the object's composition
If a traditional frame is used for structural support, then component positioning is stable, but aerodynamics and thermal management are adversely affected
Solution Approach 1:
The frame and airbox are merged into a single aerodynamically optimized structure that reduces air resistance while maintaining component positioning stability. The integrated design allows air to flow more efficiently around the engine area without compromising structural support
3Strength
If a traditional frame is used, then structural rigidity is maintained, but design complexity and manufacturing costs increase
Solution Approach 1:
By combining the frame and airbox into one integrated structure, the patent reduces the number of separate components and assembly steps. This merger simplifies the overall design while maintaining the necessary structural rigidity through the unified structure
Solution Approach 2:
The integrated airbox-frame structure serves multiple functions simultaneously, reducing the total number of components needed. This multi-functionality approach simplifies manufacturing and assembly processes while maintaining structural integrity
4Strength
If separate frame and airbox structures are used, then structural support is adequate, but air flow and thermal exchange are suboptimal
Solution Approach 1:
The integration of the airbox with the frame structure creates optimized air flow paths that improve thermal exchange. The unified structure allows better positioning of air intake and exhaust pathways, enhancing cooling efficiency without compromising structural support
