Lateral Pillion Step Storage for Motorcycle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing step structure for saddle-ride type vehicles, where the pillion step is moved upward for storage, results in an unnecessary rear projection that compromises the vehicle's design aesthetics, reducing its overall designability and appearance quality.
Innovation Solution
A step structure that allows the pillion step to be turned and stored along the lateral side of the vehicle, using a shaft and holder system with locking mechanisms, enabling the step to be hidden when not in use, thus eliminating the rear projection and improving design aesthetics and assembly efficiency.

Engineering Contradiction Analysis
1Ease of manufacture
If the pillion step is moved upward to the rear side for storage, then the step can be stored, but it creates an unnecessary rear projection that worsens the vehicle's appearance and designability
Solution Approach 1:
The pillion step is stored not in the vertical upward direction (which creates rear projection), but in the lateral horizontal direction along the vehicle's side. This dimensional change from vertical to horizontal storage eliminates the unsightly rear projection while maintaining storage functionality. The step is positioned along the lateral side of the vehicle body, integrating smoothly with the vehicle's overall shape.
Solution Approach 2:
Instead of storing the pillion step in the conventional upward vertical position, the invention inverts the storage approach by positioning it laterally along the side of the vehicle. This inversion of the storage direction transforms the problematic rear projection into a streamlined side-mounted configuration that improves appearance.
2Shape
If the pillion step is made movable and turnable, then designability is improved, but the mechanism complexity increases with shaft and holder components
Solution Approach 1:
The holder structure serves multiple functions: it supports the pillion step in the usable position, provides the turning mechanism for storage, and acts as the structural framework for the entire assembly. By making the holder multi-functional, the invention reduces the need for separate dedicated components for each function, thereby managing complexity while enabling the turnable storage capability.
Solution Approach 2:
The shaft and holder are combined into an integrated assembly where the shaft is mounted on the holder. This merging of components creates a compact turning mechanism that achieves the desired mobility and storage functionality without requiring numerous separate parts, thus managing structural complexity while maintaining design flexibility.

AI summary
A step structure for a saddle-ride vehicle includes a step that is turned in a freely derricking manner between a usage state raised in a vehicle width direction and a storage state falling along a lateral side of a vehicle. In the step structure for the saddle-ride vehicle, the step is turnably arranged with a shaft provided at an end of the step as the center. The step is also stored in such a manner wherein the shaft is positioned at the rear of the step in the storage state.
