Elastic Golf Bag Underframe for Stable Tilted Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf bag underframes suffer from instability when standing tilted due to a small ground contact area, leading to potential toppling and complex assembly, and folding underframes increase production costs.
Innovation Solution
An underframe design with a base plate, wall part, and sockets for elastic rods, featuring slits and tilted walls to allow elastic bending, enabling larger ground contact and easier assembly with a single material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a driving plate is added to the underframe to improve stability when tilted, then the stability is improved, but the device complexity increases and production cost rises
Solution Approach 1:
The patent integrates the driving plate function directly into the underframe structure by making the underframe itself tiltable relative to the bag body. This eliminates the need for a separate driving plate component, thereby reducing device complexity while maintaining the stability improvement.
Solution Approach 2:
The underframe is designed to perform multiple functions: it provides structural support, enables tilting motion for stability, and serves as the mounting surface for sockets. This multi-functionality eliminates the need for separate driving plate components, reducing assembly complexity.
2Stability of the object's composition
If a folding underframe made of different materials is used to improve stability, then the stability is improved, but the manufacturing complexity and production cost increase
Solution Approach 1:
The patent uses a single material for the entire underframe structure, eliminating the need for multi-material construction. This simplifies manufacturing processes while achieving the required stability through the tilting mechanism and elastic rod design.
Solution Approach 2:
The underframe is designed with dynamic tilting capability through the elastic rod mechanism, allowing it to adapt to different ground conditions. This dynamic behavior provides stability without requiring complex multi-material folding structures.
3Adaptability or versatility
If the underframe tilts to stand on the ground, then the supporting rods can be retreated, but the ground contact area becomes small causing instability
Solution Approach 1:
The patent introduces a tilting dimension to the underframe, allowing it to rotate relative to the bag body. This dimensional change enables the underframe to achieve a larger effective ground contact area through its tilted orientation, improving stability while maintaining rod operation flexibility.

AI summary
The present invention provides an improved underframe and the golf bag using the improved underframe, the underframe made of a single elastic material, connected to the bottom side of the golf bag body, for accommodating multiple elastic rods and a supporting frame. The underframe is integrally formed with the elastic material and comprises a base plate, a wall part surrounding the base plate, a first socket, and two second sockets. These sockets are positioned at three locations on the inner side of the wall part to allow insertion of one end of each elastic rod. The first socket is located on one side of the underframe, away from the supporting frame. Additionally, the two sides of the first socket are equipped with two slits extending from the top side of the wall part to the base plate. These slits enable the wall part and the base plate between them to flex elastically.
