Modular Exercise Apparatus with Removable Wheels and Base Skids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise equipment for athletes is either specialized and limited to outdoor use or universal but not adaptable for outdoor sports practices, lacking a versatile solution that combines the functionality of a football sled with the versatility of a weightlifting rack and trailer.
Innovation Solution
A modular workout apparatus with a base polygon and vertically-oriented members that can be used as a sled, trailer, and weightlifting rack, featuring removable wheels, adjustable human interfaces, and modular design for outdoor use on various surfaces, allowing for multiple exercise functions and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized outdoor exercise equipment like football sleds is used, then it can be used for outdoor sports practice, but it lacks versatility for other exercise purposes
Solution Approach 1:
The apparatus combines multiple exercise functions into a single unified structure. The base polygon with vertical members serves as both a sled for outdoor pushing exercises and a weightlifting rack when wheels are attached. Human interfaces can be configured for different exercise types including pushing, pulling, and bodyweight exercises, allowing one device to replace multiple specialized equipment pieces.
Solution Approach 2:
The apparatus is divided into modular components including the base polygon, vertical members, human interfaces, and removable wheels. This segmentation allows different components to be configured for different exercise modes - the same base and vertical members support both sled operation and weightlifting rack functionality when wheels are attached, reducing the need for multiple complete equipment systems.
2Adaptability or versatility
If universal exercise equipment like barbells and weights is used, then it can be used for multiple exercise purposes, but it cannot be used outdoors on various surfaces
Solution Approach 1:
The apparatus transitions between different operational modes through the dynamic attachment and removal of wheels. When wheels are attached, the apparatus functions as a portable weightlifting rack suitable for indoor use. When wheels are removed, the base polygon contacts the ground directly, transforming it into an outdoor sled that can be used on grass, turf, sand, and other outdoor surfaces. This dynamic reconfiguration enables adaptability to different environments.
Solution Approach 2:
The same base polygon and vertical member structure serves dual purposes: as a sled frame for outdoor use and as a support structure for weightlifting equipment when wheels are attached. This universal design allows the apparatus to function across different environments and exercise types without requiring completely separate equipment systems.
3Ease of operation
If fixed-location exercise equipment is used, then it provides stable exercise support, but it cannot be easily transported to different locations
Solution Approach 1:
The apparatus provides stable exercise support during use through its rigid base polygon and vertical member construction. For transportation, removable wheels can be attached to enable easy rolling movement between locations. The same structural framework that provides stability during exercise also supports the wheel attachment system, allowing the device to transition from a stationary stable structure to a mobile one when transportation is needed.
4Adaptability or versatility
If specialized outdoor equipment is used, then it can withstand outdoor conditions, but it lacks the functionality of indoor weightlifting equipment
Solution Approach 1:
The apparatus integrates both outdoor sled functionality and indoor weightlifting rack capabilities into one system. The base polygon with vertical members provides the structural framework for both modes. Human interfaces can be configured for pushing exercises when used as a sled, or for pulling and bodyweight exercises when wheels are attached and it functions as a rack, thereby covering a wide range of exercise types without requiring separate specialized equipment.

AI summary
An exercise apparatus with base horizontal members forming a base polygon and ceiling horizontal members forming a ceiling polygon and a plurality of vertical members mounted at their lower ends to the base polygon and mounting the ceiling polygon spaced from the base polygon. A human interface permits athletes to exercise, and wheels mounted to the base polygon permit transport of the apparatus and attached equipment to a field or court. The base polygon includes two parallel skids and the human interface may be a pad permitting an athlete to push the apparatus horizontally when none or two of the wheels contact the ground. When no wheels contact the ground, the apparatus may be used in the manner of a weight rack, because the apparatus will not move along the ground without substantial force being applied.
