Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional sledge hammers for exercise require two components, a hammer and a target surface, which increases cost and limits options, and do not allow for adjustable weight of the hammer head, making them unsuitable for all users.

Innovation Solution

A sledge hammer design with an elongate handle and a flexible, geometrically uniform mass affixed to the distal end, secured using a pin and notch mechanism, allowing for interchangeable and adjustable hammer heads without additional equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sledge hammers use separate hammer and target surface components, then the hammer can provide impact force, but the cost increases and options are limited

Engineering Contradiction:

Improveexercise solution optionsVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the hammer head and handle into a single integrated unit by molding the head directly onto the handle, eliminating the need for separate target surface equipment and reducing the total number of components while maintaining exercise functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated hammer design serves multiple exercise purposes without requiring additional supplemental equipment, allowing the same device to provide various workout options through different swinging motions and muscle group engagement

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional sledge hammers have fixed head weight, then manufacturing is simplified, but the hammer becomes unsuitable for users requiring different weight levels

Engineering Contradiction:

Improveweight adjustmentVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The hammer head is designed as a separable component that can be removed and replaced with heads of different weights, allowing users to adjust to their skill level while the modular design enables standardized manufacturing of interchangeable components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hammer system transitions from a static fixed-weight design to a dynamic adjustable-weight system where the head weight can be changed based on user needs, with the molding mechanism providing secure attachment for various head configurations

Inventive Principle:

Principle #15Dynamics

3Reliability

If the hammer head is securely attached to the handle, then reliability is improved, but the attachment mechanism becomes more complex

Engineering Contradiction:

Improvehammer head attachment securityVSAvoidattachment mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The hammer head and handle are molded together as an integrated unit, creating a secure attachment without requiring separate fasteners, bolts, or complex mechanical connection mechanisms

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The molding process combines the handle material and hammer head material into a unified composite structure that provides secure attachment while maintaining the integrity and functionality of both components

Inventive Principle:

Principle #40Composite materials

AI summary

A hammer with an elongate handle having a longitudinal axis, a proximal end and a distal end; a protrusion mounted at the distal end of the handle having a pin and a notch therethrough oriented along a transverse axis relative to the longitudinal axis and a flexible generally geometrically uniform mass affixed to the handle at the distal end thereof. The mass is molded onto the distal end of the handle whereby at least part of the mass extends through and fully occupies a channel in the handle and cooperates with the pin to secure the mass to the handle.
