Motorcycle Frame Merging Shock Absorber Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle frames have complex manufacturing processes, low structural stability, high weight, and difficult assembly due to numerous frame members, which limits internal space for components like the rear shock absorber and storage.
Innovation Solution
A simplified frame structure comprising two one-piece frame units connected by a single unit, with the rear shock absorber integrated into a recessed space within the frame, reducing external dimensions and allowing more space for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional motorcycle frames use multiple frame members welded together, then the frame can provide structural support, but the manufacturing process becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent merges multiple separate frame members (upper right frame, upper left frame, lower right frame, lower left frame, tail frame, and cross frames) into a single integrated frame structure. This unification eliminates the need for welding connections between multiple parts, simplifying both manufacturing and assembly processes while maintaining the necessary structural support function.
2Strength
If conventional motorcycle frames use multiple frame members, then structural coverage is achieved, but the frame weight increases
Solution Approach 1:
By consolidating multiple frame members into one integrated structure, the patent eliminates redundant materials and welding joints. This merging reduces the overall frame weight while preserving the structural coverage needed for motorcycle support and component mounting.
3Reliability
If the rear shock absorber is disposed between lower frame members, then shock absorption function is achieved, but limited space remains for storage box installation
Solution Approach 1:
The patent repositions the rear shock absorber from a horizontal arrangement between lower frame members to a vertical arrangement within a dedicated recessed space in the rear portion of the frame. This dimensional change in shock absorber placement optimizes space utilization, allowing both shock absorption function and adequate storage box installation space to be achieved.
4Ease of manufacture
If multiple frame members are welded together, then frame assembly is completed, but structural stability decreases due to welding joints
Solution Approach 1:
The patent eliminates welding joints by merging multiple frame members into a single integrated structure. This removes the weak points introduced by welding connections, thereby enhancing structural stability while still allowing for feasible manufacturing through alternative joining methods for the integrated frame.

AI summary
A motorcycle (2) includes a front frame structure (3), a rear frame structure (4), an engine (5), and a rear shock absorber (6). The rear frame structure (4) is connected to a rear end of the front frame structure (3), and includes spaced-apart first and second frame units (41, 42). The first frame unit (41) is formed as one piece, extends rearwardly, and defines a receiving space (B) that extends inwardly. The second frame unit (42) is formed as one piece and extends rearwardly. The engine (5) is mounted between the first and second frame units (41, 42). The rear shock absorber (6) is mounted inside the receiving space (B) and is connected to the first frame unit (41).
