Solution Overview

Problem

Golfers face difficulties in inserting tees into hard ground or when they have limited hand strength, as standard tees lack a mechanism to prepare the teeing ground effectively.

Innovation Solution

A golf tee insertion tool with a hub and mandrel system that creates a depression in the ground for tee insertion, allowing for easier placement of tees, with adjustable mandrel lengths and tip shapes to accommodate various tee sizes and user needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a standard golf tee is used without a ground preparation mechanism, then the device simplicity is maintained, but the ease of operation deteriorates when inserting into hard ground

Engineering Contradiction:
Improveease of tee insertionVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the ground preparation function and tee insertion function into a single integrated tool. The mandrel serves dual purposes: as a ground preparation element that creates a depression when pushed into the ground, and as a guide/receiver for the golf tee. This merging eliminates the need for separate ground preparation tools while maintaining ease of operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mandrel performs preliminary ground preparation by creating a depression before the tee is inserted. This preliminary action softens the ground and makes insertion easier, particularly for users with limited hand strength or when dealing with hard ground conditions.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If mandrels with different lengths and tip shapes are used to accommodate various tee sizes, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveaccommodation of various tee sizesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hub is designed with multiple mandrels of different lengths and tip shapes, allowing a single tool to accommodate various tee sizes and types. Each mandrel can be used independently or in combination, providing universal applicability across different golf tee specifications without requiring multiple separate tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The tool is segmented into multiple interchangeable mandrels that can be selected based on the specific tee being used. This segmentation allows users to choose the appropriate mandrel length and tip shape for different tee sizes, enhancing versatility while keeping the overall device structure modular and manageable.

Inventive Principle:
Principle #1Segmentation

AI summary

An insertion tool having a hub and a mandrel extending from the hub and including a tip that is configured to be inserted into a teeing ground to create a depression for insertion of a golf tee, wherein the mandrel is configured to receive a golf tee. The insertion tool may also have a second mandrel that is also configured to be inserted into the teeing ground to create a depression for insertion of a golf tee. The insertion tool may also include a further golf tool coupled to the hub.
