Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Heavy bags tend to swing excessively during training, causing momentum that can hinder the trainer's ability to strike effectively and potentially lead to injury, as the weight of the bag generates force that is difficult to control.

Innovation Solution

A universal attachment kit that includes a securing strap and connecting straps with tethers to an anchor, limiting the movement of the heavy bag's bottom end by securing around its perimeter and attaching to an anchor, allowing controlled swinging and reduced momentum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the heavy bag is allowed to swing freely to dissipate strike force, then the bag can absorb impact energy, but the momentum adversely affects the trainer's ability to continue exercising

Engineering Contradiction:

Improveimpact energy dissipationVSAvoidtrainer's ability to continue exercising

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The system transitions from a completely free-swinging heavy bag to a dynamically constrained system using elastic bungee cords. The bungee cords provide a dynamic restoring force that allows controlled movement while preventing excessive swinging, enabling the bag to dissipate impact energy through controlled motion rather than uncontrolled swinging.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Bungee cords are introduced as an intermediary element between the heavy bag and the fixed support structure. These cords mediate the force transmission, allowing the bag to move and absorb impact while the cords' elasticity limits the amplitude of swinging and provides a restoring force to return the bag to its neutral position.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If the heavy bag is struck with enough force to stop and reverse movement, then impact energy is dissipated, but the potential to cause injury increases

Engineering Contradiction:

Improveimpact energy dissipationVSAvoidinjury risk from uncontrolled swings

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The bungee cords provide beforehand cushioning by being pre-tensioned and positioned to catch the heavy bag before it can swing to dangerous extremes. The elastic nature of the cords allows them to stretch and absorb the reverse momentum, cushioning the bag's movement and preventing it from swinging back with enough force to cause injury.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system converts the harmful reverse momentum of the heavy bag into a beneficial elastic energy storage mechanism. When the bag swings and the bungee cords stretch, the kinetic energy is converted to elastic potential energy, which then gently returns the bag to its neutral position rather than allowing it to swing back with harmful force.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If the heavy bag momentum is controlled to allow continuous training, then training efficiency improves, but the complexity of the attachment system increases

Engineering Contradiction:

Improvetraining efficiencyVSAvoidattachment system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The attachment system is segmented into multiple independent bungee cords rather than a single complex mechanical constraint. Each cord independently manages a portion of the heavy bag's movement, and multiple cords work together to provide stable, multi-directional control. This segmentation simplifies the overall system compared to a single complex mechanical governor or brake system.

Inventive Principle:

Principle #1Segmentation

AI summary

An attachment kit for a heavy bag includes a securing strap having a length between a first end and a second end and a securing mechanism that retains the securing strap about a perimeter of the heavy bag. The kit includes a plurality of connecting straps, each of the plurality of connecting straps having a length between a first connecting end and a second connecting end, wherein the first connecting end is positioned about the securing strap. The kit includes a tether having a top end and a bottom end, the top end couples to each of the second connecting ends of the plurality of connecting straps and a bottom end is couples to an anchor. When the securing strap is secured about a perimeter of the heavy bag and the tether is secured to the anchor, movement of a lower end of the heavy bag is limited.
