Motorcycle Helmet Storage Compartment with Nested Frame Recess

Solution Overview

Problem

Straddle-type vehicles, such as scooter and underbone motorcycles, face challenges in reducing vehicle width near the seat while maintaining an adequate helmet storage compartment due to larger wheel diameters and design demands for improved ride safety and comfort.

Innovation Solution

A straddle-type vehicle design featuring a helmet storage compartment with upward protrusions forming recesses in its bottom surface, allowing the vehicle body frame to be partially housed within, thereby reducing interference and enabling a narrower vehicle width while ensuring sufficient storage capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the helmet storage compartment is provided beneath the seat, then the helmet storage function is ensured, but the vehicle width in the vicinity of the seat cannot be reduced

Engineering Contradiction:

Improvehelmet storage compartment capacityVSAvoidvehicle width

Core Design Contradiction:

Volume of moving objectVSLength of moving object

Solution Approach 1:

The vehicle body frame is nested within the recess formed by the protrusion in the helmet storage compartment bottom surface. This allows the frame to occupy the space below the compartment, effectively utilizing vertical space and reducing horizontal width requirements while maintaining both the frame structure and storage compartment functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention transitions from a horizontal arrangement where the frame and storage compartment occupy separate lateral spaces to a vertical arrangement where the frame is positioned below the compartment. The protrusion creates a recess that accommodates the frame in the vertical dimension, allowing the vehicle width to be reduced while preserving both structural and storage functions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A motorcycle 10 includes a vehicle body frame 30 that forms the frame of a vehicle body 10A and a helmet storage compartment 100 capable of storing a helmet HL. A protrusion 121 that protrudes upwards is provided in a bottom surface 110 of the helmet storage compartment 100 so as to form a recess 123 that opens toward the bottom of the motorcycle 10. At least a portion of the vehicle body frame 30 is disposed within the recess 123.
