Motorcycle Storage Case Integrating Weight Transfer Ribs

Solution Overview

Problem

Conventional vehicles with a step floor and storage case require a specialized weight transfer structure to transmit the rider's weight to the frame, increasing costs.

Innovation Solution

The vehicle integrates weight receiving and transfer portions within the storage case, allowing it to transmit the rider's weight to the frame without a separate weight transfer structure, using ribs along the frame's longitudinal and transverse directions to facilitate weight distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a specialized weight transfer structure is provided to transfer weight from the step floor to the frame, then the weight transfer function is improved, but the device complexity and cost increase

Engineering Contradiction:

Improveweight transfer functionVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The storage case is designed to integrate both storage functionality and weight transfer functionality. The weight transfer portions are formed as integral structures (such as ribs or protrusions) on the storage case, allowing it to transfer weight from the step floor to the frame while simultaneously serving as a storage container. This merging of functions eliminates the need for a separate specialized weight transfer structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The storage case is designed as a multi-functional component that performs multiple roles: (1) storing items in its hollow space, (2) transferring weight from the step floor to the frame through its weight transfer portions, and (3) providing structural support. This universal design allows a single component to fulfill multiple functions that would traditionally require separate dedicated structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A storage case (150) in a motorcycle (10) is integrally provided with: load-receiving parts (170, 182, 183a, 183b) which receive the load of a step floor (54); and load transfer parts (184, 188, 189a, 189b, 194) which transfer the load received by the load-receiving parts (170, 182, 183a, 183b) to lower frames (38).
