Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf practice devices, such as stimpmeters, are often complex, bulky, and not easily transportable, making them inconvenient for golfers to use and store.
Innovation Solution
A golf practice device with a hinged or removable design that allows for compact storage and transport, featuring a straight ramp for accurate ball acceleration, and can be anchored to the ground or used without anchoring, made of simple and economical materials like metal or plastic, with anti-slip coatings for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stimpmeter designs are used, then measurement functionality is achieved, but device complexity and bulk increase
Solution Approach 1:
The device is divided into separate modular components: a base body with anchoring means, a main body with ramp and guide rails, and an extension element. These segments can be assembled and disassembled easily, reducing overall device complexity while maintaining measurement functionality through the coordinated operation of each segment.
2Reliability
If conventional stimpmeter designs are used, then measurement functionality is achieved, but portability and ease of transport deteriorate
Solution Approach 1:
By segmenting the device into removable components that can be easily assembled and disassembled, the invention enables golfers to transport individual parts in luggage or bags, significantly improving portability while maintaining the complete measurement functionality when assembled on the green.
3Ease of manufacture
If simple and economical materials are used, then manufacturing cost is reduced, but durability and wear resistance may worsen
Solution Approach 1:
The device employs composite material construction, combining standard economical materials (plastic or metal for structural components) with specialized anti-slip coatings on the ramp surface and rubber or silicone coatings on guide rails. This composite approach maintains manufacturing simplicity while significantly improving wear resistance and functional performance.
4Manufacturing precision
If anti-slip coatings and specialized materials are added, then ball rolling performance is improved, but manufacturing complexity increases
Solution Approach 1:
Instead of treating the entire device with complex materials, the invention applies specialized coatings only to specific local areas where they are most needed: anti-slip coating on the ramp surface for ball acceleration control, and rubber/silicone coating only on the guide rails for ball guidance. This localized application maintains manufacturing simplicity while achieving precise ball rolling performance.
