Solution Overview

Problem

Existing rolling machine storage solutions are bulky, inflexible, and difficult to use, causing storage inefficiencies and stability issues in vehicle trunks, and can leave marks on floors due to direct wheel contact.

Innovation Solution

A compact, tool-free support system with a rolling ramp and self-gripping material for quick attachment, allowing for adjustable orientation and easy handling of rolling machines, while keeping them off the floor to prevent damage and instability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed motorcycle carrier occupying the entire trunk floor is used, then the rolling machine is stabilized in a vertical position, but the useful loading volume of the trunk is reduced and the device cannot be removed

Engineering Contradiction:

Improvestability of rolling machineVSAvoiduseful loading volume

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support is divided into two separate parts: a first support part with a first imprint receiving part for the first wheel, and a second support part with a second imprint receiving part for the second wheel. These parts can be used independently or together, allowing flexible configuration in the trunk space while maintaining stability when both parts are positioned.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support parts are designed to be movable rather than fixed. The first and second support parts can be independently positioned and removed from the trunk, allowing the trunk space to be dynamically adjusted for different loading needs while providing stable support when the rolling machine is stored.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If the support is made heavy and massive to support the weight of the bicycle in vertical position, then the support is stable, but it is difficult to handle and transport

Engineering Contradiction:

Improvestability of supportVSAvoidease of handling

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The support system is segmented into multiple lightweight parts rather than a single heavy structure. Each support part only needs to support portions of the rolling machine, reducing the weight of individual components while maintaining overall stability when assembled in the trunk.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each support part provides only the necessary support function for its designated wheel position, rather than the entire support structure needing to bear the full weight. This partial action approach allows lightweight individual components that collectively provide adequate support stability.

Inventive Principle:

Principle #16Partial or excessive action

3Device complexity

If the wheels are in direct contact with the boot floor, then the support structure is simple, but marks and damage are left on the floor

Engineering Contradiction:

Improvesimplicity of support structureVSAvoidfloor damage

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The support parts act as intermediary elements between the rolling machine wheels and the trunk floor. The imprint receiving parts provide a protective interface that prevents direct contact between dirty or wet wheels and the boot floor, avoiding marks and damage while maintaining a relatively simple support structure.

Inventive Principle:

Principle #24Intermediary (Mediator)
