Modular Resistance Trainer with Removable Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resistance training devices for athletes are often expensive, cumbersome, difficult to adjust, and inconvenient to store and transport, and they fail to provide predictable resistance that accounts for individual variations in strength and environmental factors.
Innovation Solution
A resistance exercise trainer kit comprising a durable bag with adjustable straps and removable weights made of low-impact filling materials, allowing for customizable resistance levels and easy storage, along with a leash that can be used for speed burst training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional weighted sleds or skids are used for resistance training, then athletic strength and endurance are improved, but the equipment becomes expensive, difficult to adjust, and inconvenient to store and transport
Solution Approach 1:
The resistance training system is divided into separate modular components: a sled body, removable weight plates, and attachment mechanisms. This segmentation allows users to easily adjust resistance by adding or removing weight plates without complex adjustments, while maintaining the ability to provide substantial resistance for strength training
Solution Approach 2:
The sled incorporates dynamic adjustment features including removable weight plates and adjustable resistance mechanisms that allow the equipment to adapt to different training levels and user strengths. This enables the same equipment to serve both beginner and advanced athletes through simple configuration changes
2Adaptability or versatility
If multiple parachutes of varying sizes are acquired to accommodate different resistance needs, then individualized training resistance is achieved, but equipment cost and storage requirements increase
Solution Approach 1:
The sled is designed as a universal training device that can accommodate multiple resistance levels through a single platform. Weight plates of different masses can be combined in various configurations on the same sled, eliminating the need for multiple specialized devices while providing customized resistance for each athlete's training needs
Solution Approach 2:
The system uses nested weight plates that can be stacked and combined within the single sled structure. Smaller weight plates fit within or alongside larger ones, allowing multiple resistance levels to be contained within one equipment unit rather than requiring separate devices for each resistance level
3Speed
If wind resistance parachutes are used for training, then athletic speed and endurance are enhanced, but resistance becomes unpredictable due to environmental factors
Solution Approach 1:
The sled uses gravitational force from weighted plates as a counterbalance to provide consistent resistance. Unlike wind-dependent parachutes, the weight-based resistance system provides predictable, controllable force that remains constant regardless of environmental conditions, allowing athletes to train speed and endurance with reliable resistance levels
4Strength
If strapping weights to the body is used for running training, then athletic strength is improved, but comfort and safety are reduced due to weight distribution issues
Solution Approach 1:
The sled acts as an intermediary between the athlete and the resistance weights. Instead of strapping weights directly to the body, the athlete pulls or pushes the sled which contains the weights. This intermediary approach provides the strength training benefits of weighted exercise while maintaining comfort and safety by allowing proper weight distribution in the sled rather than concentrated load on the body
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit provides a versatile, safe, and cost-effective means to enhance athletic endurance, speed, and strength by offering adjustable resistance that is predictable and easy to manage, reducing the risk of injury and storage challenges.
Implementation Method 1
the weighted bag impedes user movement
Implementation Method 2
a bag selectively attachable to a second end of the leash and configured for removable reception of at least one weight

AI summary
The resistance exercise trainer includes an adjustable strap wearable by a user, a leash attached to the strap at a first end and a bag attached to a second end of the leash and configured for removable reception of at least one weight. When wearing the strap and pulling the bag and the weight with the leash, the weighted bag impedes user movement thereby providing resistance exercise training. As part of the resistance exercise training, the leash may be disconnected from the strap and used individually as a jump rope and the weight may be removed from the bag and used individually in strength training exercises. Together, the strap, the leash, the bag and the weight may be used in a speed training triangle.
