Solution Overview

Problem

Existing motorcycle luggage systems face challenges such as requiring specialized tools and time for installation, being custom-built for specific motorcycles, and lacking universal compatibility across different types and sizes.

Innovation Solution

A luggage system with adjustable docks and mounts that securely attach to various motorcycles using a bracket with selectively spaced docks and beveled engagement mechanisms, allowing for easy, tool-free installation and universal fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hard-mounted luggage cases are used, then reliability and stability are improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvefirm mountingVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate components: a bracket that attaches to the motorcycle and a luggage case that attaches to the bracket. This segmentation allows each component to be optimized independently and simplifies installation, as the bracket can be pre-installed on the motorcycle without requiring complex tooling for the luggage case itself.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system incorporates adjustable elements that allow the bracket position and orientation to be modified during installation. This dynamic adjustment capability enables the system to accommodate different motorcycle models and frame geometries without requiring custom-designed brackets for each application, reducing overall system complexity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If hard-mounted luggage cases are used, then reliability is improved, but loss of time during installation increases

Engineering Contradiction:
Improvefirm mountingVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The bracket is designed to be pre-assembled with all necessary mounting hardware and attachment mechanisms before installation on the motorcycle. This preliminary preparation allows the actual installation process to be completed quickly by simply mounting the pre-assembled bracket and attaching the luggage case, rather than performing complex assembly steps during installation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If custom-built hard-mounted cases are used, then reliability for specific motorcycles is improved, but adaptability to different motorcycles decreases

Engineering Contradiction:
Improvesecure fitVSAvoidmotorcycle compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bracket is designed with universal mounting features that can accommodate multiple motorcycle models and frame types. By incorporating adjustable mounting points, standardized attachment interfaces, and flexible positioning capabilities, the same bracket design can be used across different motorcycle applications, eliminating the need for custom-built cases for each motorcycle type while maintaining secure fit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If throw-over saddle bags are used, then ease of installation is improved, but reliability and stability deteriorate

Engineering Contradiction:
Improveinstallation easeVSAvoidmounting stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system separates the mounting function (bracket) from the luggage containment function (case). The bracket provides stable, tool-free attachment to the motorcycle using simple quick-release mechanisms, while the luggage case is securely mounted to the bracket. This segmentation maintains the ease of installation of soft bags while achieving the reliability of hard-mounted cases.

Inventive Principle:
Principle #1Segmentation

AI summary

A motorcycle luggage system includes first and second mounts attached to a motorcycle. A luggage supporting bracket includes first and second docks for removable attachment to the first and second mounts. The first and second docks are selectively adjustably spaced from one another so as to correspond to the spacing of the first and second mounts on the motorcycle, so as to be able to be used with a wide variety of motorcycles.
