Leverage Training Sled With Pivotable Low-Height Bladder Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing football training sleds do not effectively train players to use muscle groups associated with the hips for fast twitch motions or to take positions on the field from a lowered position to gain leverage on an opposing player.
Innovation Solution
A leverage training sled system with a bladder member positioned near the lower portion of the contact member, allowing players to impact the sled at a similar or lower height, providing resistance and training muscle groups for fast twitch motions, and incorporating features like adjustable pressure, pivotable contact members, and sensors for performance feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the biasing member is positioned relatively high up on the training sled, then the sled is suitable for training players to push heavy objects over longer distances, but it falls short in training capacity for training players to use muscle groups associated with the hips for fast twitch motions
Solution Approach 1:
The training sled is divided into multiple biasing members positioned at different heights. The first biasing member is positioned at a first height and the second biasing member is positioned at a second height that is lower than the first height. This segmentation allows different muscle groups to be targeted through different impact heights, enabling both long-distance pushing training and fast twitch motion training simultaneously.
Solution Approach 2:
The patent introduces a vertical dimension to the training sled by positioning biasing members at different heights. This vertical differentiation creates multiple impact zones that correspond to different muscle group engagements, transforming a single-function device into a multi-functional training tool that addresses both long-distance pushing and explosive hip-driven motions.
2Adaptability or versatility
If the contact member is fixed in position, then the sled structure is simpler, but it cannot provide variable resistance angles for different training exercises
Solution Approach 1:
The contact member is made dynamic rather than fixed. It is configured to pivot between a first position and a second position, allowing the angle of resistance to change during exercise. This dynamic adjustment enables different training exercises with varying resistance angles, improving adaptability while maintaining a relatively simple pivot-based mechanism.
Solution Approach 2:
The pivoting contact member serves multiple functions by accommodating different exercise types through angle adjustment. The same contact member structure can provide resistance for both horizontal pushing exercises and angled explosive movements, making the sled versatile for various training purposes without requiring multiple separate devices.
3Adaptability or versatility
If the bladder member uses fixed pressure, then the device is simpler to manufacture, but it cannot provide adjustable resistance for different player skill levels
Solution Approach 1:
The bladder member's pressure parameter is made adjustable rather than fixed. The system allows modification of the pressure within the bladder, enabling resistance customization for different player skill levels and body weights. This parameter adjustment capability transforms a single-resistance device into an adaptable training tool while using a relatively simple inflatable bladder mechanism.

AI summary
A leverage training sled includes a first elongate member separated by a distance from a second elongate member that allows for the leverage training sled to slide along a ground surface. The leverage training sled also includes a cross member, a contact member, an upright member, and a bladder member. The cross member has a first end adjacent to a portion of the first elongate member and a second end adjacent to a portion of the second elongate member. The contact member extends from a portion of the cross member at a first angle relative to the cross member and is configured to pivot from the first angle to a second angle. The upright member also extends from the portion of the cross member. The bladder member is positioned at a height between a portion of the upright member and a portion of the contact member.
