Foldable Quadricycle Carrier for Compact Agricultural Tractors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tractor users often rely on relatives for transportation due to the economic and environmental costs associated with using the tractor for daily travel, and there is a need for a solution that enhances mobility without increasing the tractor's size or introducing significant disadvantages.
Innovation Solution
A device for carrying a motorized quadricycle on an agricultural tractor, featuring a frame with attachment points, a support that can be folded or extended, and adjustable wedges to accommodate different quadricycle sizes, allowing the tractor operator to tow a quadricycle for journeys without using the tractor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a platform is integrated onto the agricultural tractor to enable quadricycle transport, then the mobility of the tractor operator is improved, but the tractor's size and complexity increase
Solution Approach 1:
The support platform is designed to be movable between an extended position for carrying quadricycles and a folded position for compact storage. The support rotates about a vertical axis to transition between these positions, allowing the tractor to maintain a compact profile when the platform is not in use while providing full functionality when needed.
Solution Approach 2:
The platform is divided into a support structure and a separate frame assembly that can be independently positioned. The frame has attachment points for lifting arms while the support can rotate independently, allowing the system to adapt to different operational requirements without increasing the base tractor's permanent size.
2Strength
If the support is rigidly coupled to the frame, then the load-carrying capacity is maximized, but the support cannot adapt to terrain variations
Solution Approach 1:
The support is mounted to rotate about a vertical axis, allowing it to dynamically adjust its orientation in response to terrain variations. This rotational freedom enables the support to adapt to uneven ground while the lifting arms and frame maintain the structural strength needed for load-bearing operations.
