Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle frames are incompatible with different types of vehicle shells, such as those requiring reduced aerodynamic drag or increased ventilation, as they cannot effectively support various shell types.
Innovation Solution
A vehicle frame design featuring a frame body with interconnected backbone sections and a coupling device with sliding first coupling members that can switch between mobile and stationary states, allowing for the mounting and positioning of various accessories, including vehicle shells, through adjustable screw sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional vehicle frame is used, then the frame structure is simple and easy to manufacture, but the frame cannot support different types of vehicle shells with varying specifications
Solution Approach 1:
The backbone member is divided into multiple backbone sections that can be independently adjusted. Each backbone section can be positioned at different locations along the backbone member to accommodate various shell types and sizes, allowing the frame to adapt without requiring complete structural changes
Solution Approach 2:
The coupling device enables dynamic adjustment of the backbone sections along the backbone member. The sections can be moved to different positions and locked in place, transforming the static frame structure into a dynamically adjustable system that can adapt to different vehicle shell specifications
2Adaptability or versatility
If the backbone member has fixed backbone sections, then the manufacturing precision is high and the structure is stable, but the adaptability to different accessories is reduced
Solution Approach 1:
The coupling device is pre-configured with multiple positioning locations along the backbone member. These pre-established positions ensure that when backbone sections are adjusted, they can be accurately positioned and locked at predetermined locations, maintaining manufacturing precision while enabling adaptability
Solution Approach 2:
The system allows changing the positional parameter of the backbone sections along the backbone member. By adjusting the position parameter of each backbone section to different predetermined locations, the system achieves both flexibility for different accessories and precision through standardized positioning points
3Ease of operation
If the coupling device allows free movement of first coupling members, then the ease of operation is high for positioning accessories, but the stability of accessory mounting is reduced
Solution Approach 1:
The first coupling members transition between a mobile state where they can slide along the backbone sections for easy positioning, and a stationary state where they are locked in place to secure accessories. This dynamic state change enables both ease of operation during adjustment and stability during operation
Solution Approach 2:
The coupling device is designed with preliminary locking mechanisms at predetermined positions. When the first coupling members reach the desired position, the locking mechanism engages to secure the accessory firmly, ensuring stability while the ease of operation is maintained during the adjustment process

AI summary
A vehicle frame includes a frame body that includes a front wheel connecting member, a rear wheel connecting member, and a backbone member interconnecting the front and rear wheel connecting members and having a plurality of backbone sections interconnected to each other, and a coupling device that includes a plurality of first coupling members, each of which is mounted to a corresponding one of the backbone sections and is operable to switch between a mobile state and a stationary state. Each of the first coupling members is movable along the corresponding one of the backbone sections in the mobile state, and is immobilized relative to the corresponding one of the backbone sections in the stationary state.
