Foldable Golf Trolley Single-Action Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable golf trolleys require multiple steps to set up, making them time-consuming to transition between operational and transport modes.
Innovation Solution
A golf trolley design featuring a handle portion pivotably attached to a main frame, with main wheel mounts that rotate and linearly move in conjunction with the handle, allowing for a single action to switch between operational and transport modes, and incorporating a telescopic rod for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the golf trolley is made foldable for compact transportation, then the transport space requirement is reduced, but the setup time increases due to multiple steps required to assemble the trolley before use
Solution Approach 1:
The patent combines multiple independent folding operations (handle folding and wheel mount folding) into a single integrated mechanism. When the handle is folded, it simultaneously triggers the wheel mounts to fold and the telescopic rod to extend, achieving compact configuration in one motion. Conversely, unfolding the handle automatically deploys all components to operational positions, reducing setup time while maintaining compact transport volume.
2Volume of moving object
If multiple components are folded independently to achieve compact size, then the transport configuration is optimized, but the operational complexity increases with multiple steps required
Solution Approach 1:
The patent implements a self-service mechanism where folding the handle automatically triggers the wheel mounts to fold and the telescopic rod to extend without requiring separate manual operations. The mechanical linkage system ensures that one user action (folding the handle) automatically performs multiple configuration changes, making the system easy to operate while achieving compact transport configuration.
3Volume of moving object
If the handle and wheel mounts are folded separately, then each component can be optimized for compactness, but the overall setup process becomes time-consuming
Solution Approach 1:
The patent incorporates a telescopic rod that is pre-positioned and mechanically linked to the handle and wheel mounts. When the handle is folded, the telescopic rod is already in position to automatically extend and trigger the wheel mount folding action. This preliminary positioning of components ensures that the entire folding sequence occurs simultaneously and rapidly, optimizing both compactness and setup speed.

AI summary
The invention is directed to a golf trolley comprising a main frame for mounting a golf bag, a handle portion, which is pivotably attached to the main frame at a handle joint, a first main wheel attached to a first main wheel mount, wherein the first main wheel mount is pivotably attached to the main frame, pivotable about a swivel axis. For easy folding and unfolding of the golf trolley, the first main wheel mount is displaceable parallel to the swivel axis, wherein the handle portion is mechanically coupled to the first main wheel mount such that folding the handle portion at the handle joint drives the first main wheel mount to rotate about the swivel axis and to move linearly along the swivel axis.
