Rotatable Motorcycle Luggage Holder for Load Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle case and luggage holder devices often worsen driving conditions due to asymmetrical load distribution and protruding baggage, which affects handling, especially on high-performance motorcycles, and can lead to parking space issues due to increased volume.
Innovation Solution
A rotatable case and luggage holder device that allows suitcases or trunks to be positioned either within the motorcycle's outline for improved stability or protruding rearwardly, depending on passenger presence, using a fastening structure with adjustable rotation axis and locking mechanisms for easy engagement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a trunk or suitcase is positioned protruding rearwardly from the motorcycle, then the load capacity is improved, but the driving conditions worsen due to asymmetric load distribution and increased distance from the center of gravity
Solution Approach 1:
The support means are made rotatable about a vertical axis, allowing the load position to be dynamically adjusted between a first position (protruding rearwardly) and a second position (within the motorcycle outline). This dynamic repositioning resolves the contradiction by enabling the system to adapt to different operational requirements - maximizing load capacity when needed while maintaining good driving conditions when the load must be kept close to the center of gravity
Solution Approach 2:
The invention introduces rotation about a vertical axis as a new degree of freedom, transitioning the load positioning from a single fixed location to a multi-position system. This dimensional change allows the load to be positioned in different spatial configurations - protruding rearwardly for maximum capacity or within the motorcycle outline for optimal handling - thereby resolving the contradiction between load capacity and driving conditions
2Quantity of substance
If a trunk or suitcase is positioned protruding rearwardly from the motorcycle, then the load capacity is improved, but the overall vehicle volume increases leading to parking space issues
Solution Approach 1:
The rotatable support means enable the vehicle volume to be dynamically adjusted. When parking is required, the support means can be rotated to bring the load within the motorcycle outline, effectively reducing the vehicle's overall volume to fit standard parking spaces. This resolves the contradiction by allowing the system to maximize load capacity during transport while minimizing vehicle volume during parking
Solution Approach 2:
By introducing rotation about a vertical axis, the invention transforms the load positioning from a fixed extended configuration to a multi-position system that includes a compact configuration. This dimensional change allows the load to be positioned within the motorcycle outline when needed, effectively reducing the vehicle's longitudinal volume and resolving the parking space issue while maintaining load capacity
3Device complexity
If the support means are fixed in position, then the device complexity is reduced, but the adaptability to different usage conditions (with or without passenger) is limited
Solution Approach 1:
The support means are designed to be rotatable rather than fixed, introducing a simple rotational mechanism that provides adaptability without significantly increasing device complexity. The rotation about a vertical axis allows the system to adapt to different usage conditions - positioning the load protruding rearwardly when no passenger is present and positioning it within the motorcycle outline when a passenger is present - while maintaining relatively simple device architecture
Solution Approach 2:
The rotatable support means serve multiple functions: they can position the load for optimal capacity when no passenger is present, and they can position the load within the motorcycle outline to serve as a backrest when a passenger is present. This multi-functionality resolves the contradiction by enabling the same device structure to adapt to different usage conditions without requiring entirely separate systems
