Removable Cargo Rack Mounting System for Straddle Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for cargo boxes on straddle-type vehicles are often difficult to remove, can damage the vehicle's frame, and leave an aesthetically unpleasant appearance when not in use, lacking a user-friendly and adaptable solution for mounting and dismounting racks and cargo boxes.
Innovation Solution
A kit with removable brackets that connect to the vehicle's frame at three points, including a foot peg holder and turn signal holder, using quarter-turn fasteners and intermediate brackets for easy installation and removal of a cargo box or saddle bag rack, ensuring an aesthetically pleasing look and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rack is made removable with fasteners, then ease of operation is improved, but device complexity increases due to additional fasteners and mounting components
Solution Approach 1:
The mounting system is divided into separate components: the rack, intermediate brackets, and quarter-turn fasteners. This segmentation allows the rack to be easily removed by detaching the fasteners from the intermediate brackets, which remain mounted to the vehicle frame. The segmentation enables independent removal of the rack without removing the entire mounting system.
Solution Approach 2:
Intermediate brackets are introduced as intermediary components between the vehicle frame and the rack. These brackets provide mounting points for the quarter-turn fasteners and remain permanently attached to the frame, serving as a mediator that allows the rack to be easily attached and removed while maintaining a clean appearance when the rack is not in use.
2Reliability
If the rack is made permanently fixed, then reliability is improved, but ease of operation deteriorates due to difficulty in removal
Solution Approach 1:
The mounting system is segmented into permanent components (intermediate brackets attached to the frame) and removable components (rack with fasteners). This segmentation maintains reliable mounting through the securely attached intermediate brackets while enabling easy removal of the rack by simply detaching the quarter-turn fasteners.
Solution Approach 2:
The mounting system transitions from a static permanent fixation to a dynamic system where the rack can be easily attached and removed. The quarter-turn fasteners provide a mechanism that allows the rack to be quickly secured and released, changing the operational state from fixed to movable as needed.
3Adaptability or versatility
If the rack is made removable, then adaptability is improved, but object-generated harmful factors increase due to potential damage during removal
Solution Approach 1:
The intermediate brackets serve as protective mediators between the vehicle frame and the removable rack. They are permanently mounted to the frame with robust fasteners, providing stable anchor points that distribute removal forces and prevent damage to the vehicle frame during rack installation and removal operations.
Solution Approach 2:
The mounting system is designed with pre-positioned intermediate brackets and quarter-turn fasteners that guide the rack into proper alignment during installation. This beforehand preparation ensures correct positioning and prevents misalignment damage, while the robust construction of the intermediate brackets cushions against removal forces.
4Reliability
If the rack remains on the vehicle when cargo box is removed, then reliability is improved, but appearance deteriorates due to unpleasant look
Solution Approach 1:
The rack is designed to be completely removable from the intermediate brackets using the quarter-turn fasteners. When the cargo box is not in use, the rack can be entirely detached and removed from the vehicle, leaving only the intermediate brackets mounted to the frame. This extraction of the rack eliminates the aesthetic issue of an unwanted rack remaining visible on the vehicle.
