Innovation Solution

A swing motion trainer with a rod portion and interchangeable resistance mechanisms, including removable resistance elements such as weighted balls and elastic attachments, provides resistance to simulate golf swings and improve muscle strength and swing speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional golf training devices are used, then swing speed can be improved, but strength enhancement is not achieved simultaneously

Engineering Contradiction:
Improveswing speedVSAvoidmuscle strength
Core Design Contradiction:
SpeedVSStrength

Solution Approach 1:

The device employs interchangeable resistance elements (weights, springs, elastic bands) that can be attached and removed from the rod portion, allowing dynamic adjustment of training intensity. This enables the same device to provide both speed training (with lighter resistance) and strength training (with heavier resistance) by simply changing the attachment element.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The training device is designed with a universal interface on the rod portion that accepts multiple types of resistance elements. This multi-functionality allows a single device to address both swing speed development and muscle strength enhancement, eliminating the need for separate training devices for each objective.

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

2Adaptability or versatility

If fixed resistance elements are used in training devices, then device complexity is reduced, but adaptability to different training needs is limited

Engineering Contradiction:
Improvetraining program adaptabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The resistance system is segmented into separate interchangeable elements (weights, springs, elastic bands) that can be independently selected and attached to the rod portion. This segmentation allows users to customize resistance levels and types without complicating the core device structure, as each element is a simple, standalone component.

Inventive Principle:
Principle #1Segmentation
