Solution Overview

Problem

The high cost and space requirements of purchasing multiple types of exercise equipment, such as dumbbells, kettlebells, and barbells, to perform a variety of exercises effectively, as each type provides different muscle workouts, are addressed by a clamp that allows for interchangeable handles.

Innovation Solution

A clamp for exercise equipment with a body, hinge, neck, and securing mechanism that can attach to different handle types, enabling conversion between dumbbell, kettlebell, and barbell exercises using a single set of weights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user purchases multiple types of exercise equipment (dumbbells, kettlebells, barbells) to perform diverse exercises, then the variety of muscle workouts is improved, but the cost and storage space requirements increase

Engineering Contradiction:
Improveexercise varietyVSAvoidequipment quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The clamp is designed with a universal interface that can accommodate multiple handle types (dumbbell handles, kettlebell handles, barbell handles) through a single standardized coupling mechanism. The clamp body with adjustable clamping arms and the neck with protrusions create a universal attachment system that allows one clamp to function with various exercise equipment types, enabling a single set of weights to be used for diverse exercises including dumbbell presses, kettlebell swings, and barbell rows

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

Solution Approach 2:

The exercise equipment is divided into separable components: the clamp assembly (including clamp body, hinge, and neck) and the handle types. This segmentation allows the clamp to be detached and reattached to different handle types, enabling users to switch between exercise configurations without needing separate equipment sets. The hinge connection and protrusion-indentation mating mechanism facilitate this modular segmentation and reconfiguration

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a user purchases multiple types of exercise equipment (dumbbells, kettlebells, barbells) to perform diverse exercises, then the variety of muscle workouts is improved, but the storage space requirements increase

Engineering Contradiction:
Improveexercise varietyVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The clamp creates a universal interface that allows a single set of weights to be used for multiple exercise types by attaching different handle configurations. Instead of requiring separate storage spaces for dumbbells, kettlebells, and barbells, users only need to store one clamp assembly with their weight set, significantly reducing the storage area needed while maintaining access to diverse exercise capabilities

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

3Ease of operation

If a user uses a clamp with a hinge connection to attach handles, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvehandle attachmentVSAvoidclamp structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The hinge connection introduces dynamic capability to the clamp, allowing the clamping arms to move between open and closed positions for easy handle attachment and detachment. This dynamic mechanism simplifies operation by enabling users to quickly open the clamp, position the handle, and then close it securely, all through a simple hinge motion rather than requiring complex adjustment mechanisms

Inventive Principle:
Principle #15Dynamics

AI summary

A clamp for exercise equipment. The clamp includes a body. The body is configured to receive a portion of a piece of exercise equipment. The body includes a first portion, a second portion and a hinge connecting the first portion and the second portion. The clamp also includes a neck. The neck is cylindrical in shape. The neck includes a first portion attached to the first portion of the body and a second portion attached to the second portion of the body. The clamp further includes a securing mechanism, the securing mechanism configured to secure the first portion of the neck to the second portion of the neck. The neck is configured to secure to an external handle when secured by the securing mechanism.
