Golf Tee Protrusion Groove Coupling Impact Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf tees are costly to manufacture, difficult to assemble, and inconvenient to use due to the use of magnets and bolts, and require frequent adjustment and fine control to restore the support and rotary members to a vertically aligned position after hitting a golf ball.
Innovation Solution
A golf tee design featuring a support inserted into the ground and a rotatable rotary portion with a coupling mechanism using protrusions and receiving grooves, allowing easy adjustment and restoration to a vertical position, manufactured through injection molding with different materials and conditions to ensure secure coupling and minimize damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If magnets and bolts are used to couple the support and rotary portion, then the coupling strength is improved, but the manufacturing cost increases and assembly difficulty increases
Solution Approach 1:
The patent removes magnets and bolts from the coupling mechanism, replacing them with a simple protrusion-receiving groove structure. This extraction of complex components directly reduces manufacturing cost and assembly difficulty while maintaining coupling functionality through the integrated molding process.
Solution Approach 2:
The support and rotary portion are merged into a single integrated structure through injection molding, where the protrusion and receiving groove are formed as part of the molding process itself. This merging eliminates the need for separate coupling components and simplifies both manufacturing and assembly.
2Stability of the object's composition
If the rotary portion is firmly fixed to the support, then structural stability is improved, but the ability to rotate during impact is reduced and damage risk increases
Solution Approach 1:
The coupling mechanism transitions from a static firm fixation to a dynamic structure that allows controlled rotation during impact. The protrusion-receiving groove design provides stable positioning during normal use but permits rotational movement when force is applied, absorbing impact energy and preventing damage.
Solution Approach 2:
The receiving groove structure is designed in advance to accommodate and absorb impact forces through controlled rotation. This pre-designed cushioning mechanism protects the golf tee from damage by allowing the rotary portion to rotate during impact rather than being rigidly fixed.
3Ease of operation
If the rotary portion can rotate freely, then ease of adjustment is improved, but the ability to restore to vertical position automatically is reduced
Solution Approach 1:
The protrusion-receiving groove structure enables self-alignment and automatic restoration to the vertical position. After rotation during impact, the geometry of the protrusion and groove guides the rotary portion back to its correct orientation without requiring manual intervention or fine control adjustments.
Solution Approach 2:
The asymmetric geometry of the protrusion and receiving groove creates a preferred vertical position. The asymmetric design allows free rotation during adjustment but provides a natural stopping point and alignment reference that automatically restores the correct vertical orientation after impact.

AI summary
Disclosed herein are a golf tee used when a golfer hits a tee shot and a method of manufacturing the same. The golf tee includes a support inserted into the ground and a rotary portion coupled to the support and having a head on which a golf ball is placed, wherein the rotary portion is adjustable in angle and thus can be easily restored to a correct vertical position when the angle of the rotary portion with respect to the support is changed due to impact upon hitting.
