Motorcycle Frame Storage Layout for Stable Heavy Load Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeled vehicles with loading capabilities struggle to transport bulky and heavy loads without disrupting the vehicle's balance, leading to stability issues and reduced maneuverability.
Innovation Solution
A vehicle structure with a frame design featuring lower and upper crossbars that create a spacious, laterally accessible compartment, allowing for the transportation of large and heavy objects while maintaining the vehicle's center of gravity within safe limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a rear carrier or side bags are used for loading objects, then the vehicle can transport small luggage, but it cannot transport bulky loads due to structural limitations
Solution Approach 1:
The patent introduces a lateral access dimension by creating an opening in the left lateral side of the frame, allowing objects to be inserted from the side rather than only from above or behind. This dimensional change enables access to the storage compartment without requiring the vehicle structure to be opened or disassembled, effectively increasing the practical storage capacity while maintaining structural integrity.
Solution Approach 2:
The frame is segmented to create a dedicated storage compartment separated from the main vehicle structure. The longitudinal bar and transverse bars form a distinct compartmentalized space, allowing independent loading and unloading of luggage without affecting the rider or driver area, thus increasing effective storage volume.
2Volume of moving object
If a removable receptacle under the handlebar is used, then the vehicle can transport objects, but the barycentre advances causing instability under braking
Solution Approach 1:
The storage compartment is positioned in the central region of the frame between the front and rear wheels, utilizing the lateral dimension rather than placing loads at the extreme front or rear. This central positioning maintains the barycentre within acceptable limits, preventing the instability and braking issues caused by forward weight shift.
3Volume of moving object
If a rear carrier is used, then the vehicle can transport loads, but the barycentre moves backward reducing directional control
Solution Approach 1:
Instead of placing the storage compartment at the rear extreme (which would shift the barycentre backward), the patent positions it centrally within the frame structure, between the front and rear wheels. This central positioning in the longitudinal dimension maintains proper weight distribution and directional control while still providing adequate storage capacity.
4Device complexity
If the frame has downward arcuated crossbars, then the frame structure is formed, but lateral access is limited reducing loading capacity
Solution Approach 1:
The frame is segmented by introducing a lateral opening in the left lateral side, creating a dedicated access point that separates the loading function from the structural framework. This segmentation allows the frame to maintain its structural integrity while providing easy lateral access for loading, effectively increasing loading capacity without complicating the overall frame design.
