Solution Overview

Problem

Conventional weight sleds for resistance training are bulky, require significant space for storage, and lack feedback mechanisms for tracking exercise activity, necessitating a compact and informative training solution.

Innovation Solution

A foldable weight training sled with fixed and foldable push bars, rotatable wheels, and integrated measurement devices that provide training information, allowing for compact storage and real-time exercise tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional weight sleds are designed with fixed structure and full-size push bars, then structural strength and usability are improved, but storage space requirements increase significantly

Engineering Contradiction:

Improvestructural strengthVSAvoidstorage space

Core Design Contradiction:

StrengthVSArea of stationary object

Solution Approach 1:

The sled is divided into modular components including a collapsible frame structure that can be disassembled into separate sections for storage, allowing the strong functional structure to be broken down into compact storage units

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The push bars are designed to be collapsible and adjustable rather than fixed, allowing them to transition from a full-size functional state during exercise to a compact folded state for storage, maintaining structural integrity while reducing storage footprint

Inventive Principle:

Principle #15Dynamics

2Loss of information

If measurement devices are integrated into the sled, then exercise tracking capability is improved, but device complexity increases

Engineering Contradiction:

Improveexercise trackingVSAvoiddevice complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The sled automatically tracks exercise metrics through integrated sensors that detect movement, distance, and intensity without requiring manual input from the user, providing comprehensive exercise information while maintaining simple operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual tracking methods are replaced with electronic sensors and digital display systems that automatically measure and record exercise parameters, reducing the need for complex manual tracking mechanisms while providing accurate data

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If foldable push bars are implemented, then storage compactness is improved, but ease of operation during exercise may be compromised

Engineering Contradiction:

Improvestorage spaceVSAvoidease of operation

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The push bars feature a quick-collapse mechanism that allows them to transition rapidly between folded and extended states, ensuring they are fully functional during exercise while enabling compact storage when not in use

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The push bars are pre-configured with locking mechanisms and ergonomic grips that ensure they are ready for immediate use when extended, eliminating setup time and ensuring ease of operation during exercise sessions

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed is a foldable weight training sled for training, where the foldable weight training sled is moved along a substantially linear longitudinal direction. The foldable weight training sled includes a chassis, a first pair of fixed rotatable wheels, a second pair of fixed rotatable wheels, a first pair of foldable push bars, a second pair of foldable push bars, and a measurement device. The foldable push bars may be moved between an upright deployed position, and a folded position wherein the push bars rest along a top side of the chassis.
