Tow Dolly With Adjustable Wheel Axis for Cars and Motorcycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions do not efficiently provide a single device capable of towing both vehicles and motorcycles, as existing tow dollies are either designed for vehicles or motorcycles, lacking versatility in supporting both types simultaneously.
Innovation Solution
A dolly system with a chassis and wheels that can couple to a tow vehicle, featuring a design that allows it to support either a vehicle or a motorcycle by adjusting the wheel axis of rotation, enabling the towing of both types of vehicles sequentially or simultaneously, with integrated loading ramps and tie-downs for secure transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single dolly is designed to accommodate both vehicles and motorcycles, then versatility is improved, but device complexity increases
Solution Approach 1:
The dolly employs an adjustable wheel axis of rotation that can be repositioned between a first position for accommodating vehicles and a second position for accommodating motorcycles. This dynamic reconfiguration allows the same dolly structure to adapt to different vehicle types without requiring multiple specialized devices, thereby improving versatility while managing complexity through a single adjustable mechanism rather than multiple fixed configurations
Solution Approach 2:
The dolly is designed with universal features including adjustable wheel axes, reconfigurable support surfaces, and adaptable securing mechanisms that can accommodate both vehicles and motorcycles. The wheel axis can be positioned at different locations on the dolly chassis, and the support structure can be reconfigured to match the geometry of different vehicle types, making the device universally applicable to multiple vehicle categories
2Adaptability or versatility
If the wheel axis of rotation is repositioned to accommodate different vehicle types, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The dolly wheel axis is pre-positioned at standardized locations that are optimized for different vehicle types. The axis can be quickly repositioned between predetermined first and second positions rather than requiring continuous adjustment, which simplifies the operator's task while maintaining adaptability. The support surfaces and securing points are also pre-configured to match common vehicle geometries, reducing the cognitive and physical effort required for setup
Solution Approach 2:
The dolly structure is segmented into modular components including the wheel axis, support surfaces, and securing mechanisms that can be independently adjusted or reconfigured. This segmentation allows the wheel axis to be repositioned without affecting other critical functions, and enables operators to make localized adjustments rather than reconfiguring the entire system, thereby improving ease of operation while maintaining adaptability
