Exercise Device With Interchangeable Weighted Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for exercise devices that simulate swinging a sledgehammer without causing damage typically associated with solid steel heads, which existing devices fail to address effectively.
Innovation Solution
The exercise device comprises a weighted head with a handle and an attachment system using a cap and connector that securely attaches to a receiver, allowing for interchangeable weighted heads of different weights, utilizing materials like sand or rubber for flexible weight distribution and a quick-release connector for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a solid steel head is used in a sledgehammer, then the device provides sufficient weight and durability, but it causes damage to surfaces and creates safety hazards during exercise
Solution Approach 1:
The patent introduces a receiver component as an intermediary between the weighted head and the handle. This receiver acts as a mediator that allows the weighted head to be attached and detached without permanent attachment, enabling the use of different weighted heads with different surface impact characteristics while maintaining the structural integrity provided by the receiver design.
Solution Approach 2:
The patent changes the physical state and properties of the weighted head by using fillable containers that can be adjusted with sand or other materials. This allows the weight and surface characteristics to be modified, providing a softer impact surface compared to solid steel, while still achieving the necessary weight for exercise effectiveness.
2Reliability
If a fixed attachment system is used, then the weighted head remains securely attached, but it prevents easy adjustment of weight and replacement of components
Solution Approach 1:
The patent divides the sledgehammer into separate, interchangeable components: a handle, a receiver, and multiple weighted heads. This segmentation allows each component to be independently selected and attached based on exercise requirements, enabling easy weight adjustment and component replacement while maintaining secure attachment through the receiver design.
Solution Approach 2:
The patent implements a dynamic attachment system where the weighted head can be easily attached and detached from the receiver. This dynamic capability allows users to adjust the weight and characteristics of the exercise device during use, providing versatility while maintaining reliability through the secure receiver attachment mechanism.
3Weight of moving object
If a heavy weighted head is used, then the exercise effectiveness increases, but it increases the risk of injury and requires greater user strength
Solution Approach 1:
The patent allows modification of the weighted head parameters by filling containers with varying amounts of sand or other materials. This enables users to adjust the weight to match their strength level, providing progressive overload for exercise effectiveness while reducing injury risk by starting with lighter configurations and gradually increasing weight as strength improves.
