Solution Overview

Problem

Existing portable gym systems that mount exercise equipment to shipping containers through holes in the walls cause water intrusion, animal infestation, damage to the container, and structural instability, while limiting exercise height and flexibility.

Innovation Solution

A rooftop mount device that attaches exercise equipment to the roof of a container using connection members and horizontal stabilization members, allowing for adjustable attachment points without penetrating the container walls, ensuring stability and sufficient exercise height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wall-mounted portable gym systems are used to attach exercise equipment to container walls, then exercise equipment can be installed and used, but water intrusion, animal infestation, and damage to the container occur due to holes drilled through the walls

Engineering Contradiction:
Improveexercise equipment installationVSAvoidwater intrusion and animal infestation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from wall-mounted (vertical dimension) to rooftop-mounted (horizontal dimension) exercise equipment. By attaching equipment to the roof surface rather than drilling through side walls, the system eliminates penetration holes that cause water intrusion and animal infestation while maintaining exercise functionality

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a rooftop mounting system as an intermediary solution between the container and exercise equipment. This mounting system attaches to the roof surface without penetrating the container walls, serving as a mediator that enables equipment installation while protecting the container from water and animal damage

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If mounting equipment is installed through holes in the container walls, then exercise equipment can be attached, but the structural integrity of the container is compromised and wall failure may occur under weight loads

Engineering Contradiction:
Improveequipment attachmentVSAvoidcontainer wall integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent moves the mounting location from vertical side walls to the horizontal roof surface. This dimensional change allows equipment to be supported by the roof structure rather than compromising wall integrity, eliminating the risk of wall failure under exercise equipment loads

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent extracts the mounting function from the container walls and relocates it to the roof surface. By separating the mounting function from the wall structure, the system enables equipment attachment without compromising wall strength or risking structural failure

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If exercise equipment is mounted to the side walls of the container, then equipment installation is possible, but the height of the container limits the available exercise clearance

Engineering Contradiction:
Improveequipment installationVSAvoidexercise clearance height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The patent transitions from side-wall mounting to rooftop mounting, utilizing the horizontal roof surface and vertical space above the container. This allows exercise equipment to be positioned at optimal heights for full range of motion, eliminating the height limitations imposed by container wall height

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A rooftop mount device for connecting to a roof of a portable gym and for attaching exercise equipment is described. The portable gym is a portable container, such as a shipping container, having a top surface, or roof, to which the rooftop mount is attachable. The rooftop mount device includes connection members. The rooftop mount can also include one or more horizontal stabilization members and equipment attachment elements. The connection members are attached to a roof of the container. Exercise equipment is attached to the parts of the rooftop mount device. The rooftop mount provides proper height and stability for the bars, racks, stands, cages, rigs and riggings, and other exercise equipment that are attached to the container's roof so that the equipment does not move during use by an exerciser. Systems and kits are also described, which include a rooftop mount device, various exercise equipment, and a portable container.
