Motorcycle Frame Storage Space Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs of motorcycle body frames, which aim to increase storage capacity by widening the distance between the left and right frame sections, face interference issues when trying to take in and out objects due to the shape and structure of the frame, limiting ease of access to the storage space.
Innovation Solution
The motorcycle features integrally formed cast left and right frame sections with specific cross-sectional shapes and the inclusion of extrusion members, a storage box, and elastic members to facilitate easy access and increased storage capacity without widening the vehicle's overall width, with the frame sections and storage box designed to accommodate a larger capacity and ease of object handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the distance between the left and right frame sections is extended to enlarge storage capacity, then the storing capacity is increased, but the opening for taking in and out stored objects interferes with the access
Solution Approach 1:
The frame sections are designed with a trapezoidal cross-section where the distance between left and right sidewalls increases from bottom to top. This dimensional variation along the vertical axis allows the storage space to be enlarged without increasing the overall vehicle width, and the opening is positioned at the top where sufficient width exists for easy access
2Ease of manufacture
If the frame sections are made by casting to simplify manufacturing, then the manufacturability is improved and number of parts is reduced, but the structural complexity increases
Solution Approach 1:
The body frame is divided into left and right frame sections that are cast separately and then joined together. This segmentation allows each section to be manufactured independently using casting processes, simplifying production while the specific trapezoidal geometry of each section provides the necessary structural strength and creates the enlarged storage space

AI summary
The present application relates to a motorcycle, in particular scooter type motorcycle, comprising: a body frame having left and right frame sections (13), both extending in a longitudinal direction of the motorcycle; the left frame section (13) having a left sidewall (13a) and the right frame section (13) having a right sidewall (13a), wherein a storage space is formed between the left and right sidewalls (13a) and in an upper area of the sidewalls (13a) a distance between the left and right sidewalls (13a) in a width direction of the motorcycle is greater than in a lower area of the sidewalls (13a).
