Extendable Golf Trolley Frame for Variable Bag Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf-bag trolleys are limited in their applicability due to a fixed distance between the upper and lower bag supports, accommodating only golf bags of specific heights, failing to cater to bags of varying sizes and heights for different users.
Innovation Solution
A golf-bag trolley with an extendable frame comprising an upper and lower tube, where the upper tube can be adjusted within the lower tube using a locking mechanism, allowing the distance between the bag supports to be adjusted to fit golf bags of different heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between upper and lower bag supports is fixed, then the structural simplicity is maintained, but the adaptability to different golf bag heights is reduced
Solution Approach 1:
The frame structure is transformed from a fixed static configuration to a dynamic adjustable one. The upper tube can slide within the lower tube to change the distance between bag supports, allowing the trolley to adapt to different golf bag heights while maintaining operational simplicity through the locking mechanism
Solution Approach 2:
The frame is divided into separable components (upper tube and lower tube) that can independently move relative to each other. This segmentation enables the upper tube to be adjusted to different positions within the lower tube, providing adaptability while keeping each component relatively simple in design
2Adaptability or versatility
If the upper tube is made movable within the lower tube, then the adjustability for different bag heights is improved, but the structural stability may be compromised
Solution Approach 1:
The frame provides dynamic adjustability during setup, allowing the upper tube to be positioned at different heights. Once positioned, the locking mechanism locks the tubes together to provide static stability during use, ensuring the frame maintains its shape and does not collapse under the weight of the golf bag
Solution Approach 2:
The locking mechanism acts as an intermediary between the movable upper tube and the fixed lower tube. It temporarily secures the upper tube at the desired position, preventing unwanted movement while maintaining the adjustability feature, thus bridging the gap between mobility and stability requirements

AI summary
The invention discloses a golf-bag trolley with an extendable frame, comprising a front wheel set, a left rear wheel set, a right rear wheel set, a handle set, a frame, a connecting base, an upper bag support and a lower bag support, wherein the front wheel set is installed at a front end of the lower bag support, the left rear wheel set is installed on the connecting base and is located on a left side of the connecting base, the right rear wheel set is installed on the connecting base and is located on a right side of the connecting base, the frame comprises an upper tube and a lower tube, the upper tube has a smaller outer diameter than the lower tube, a lower part of the upper tube is inserted into the lower tube, the lower bag support is installed at a lower end of the lower tube, the handle set is installed at an upper end of the upper tube, the upper bag support is installed on the upper tube, and a locking mechanism is arranged between the lower tube and the upper tube. When the locking mechanism is locked, the lower tube and the upper tube are relatively fixed. When the locking mechanism is unlocked, the upper tube is movable in the lower tube and can be locked again. The golf-bag trolley is widely applicable and can be used for golf bags of different heights.
