Solution Overview
Problem
There is a need for a practical exercise device that can effectively engage and maintain numerous muscle systems within a minimal weight, complexity, and bulk, allowing for indoor use regardless of ambient weather conditions.
Innovation Solution
A compact exercise device featuring a flat frame with parallel slide members constrained by elastic tethers, allowing users to perform leg thrust exercises against resistance, with optional simultaneous or alternating leg movements, and a hand grip for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a compact exercise device is designed with minimal weight and bulk, then portability and space efficiency are improved, but the ability to provide sufficient resistance and engage multiple muscle systems deteriorates
Solution Approach 1:
The slide members are designed to perform multiple functions: they provide resistance through elastic tethers, guide foot placement for proper exercise form, and enable various exercise movements (forward, backward, lateral). This multi-functionality allows a single compact component to engage multiple muscle groups without adding weight or bulk to the device.
2Device complexity
If the device structure is simplified to reduce complexity, then ease of manufacture and maintenance are improved, but the effectiveness in providing controlled resistance and tracking motion deteriorates
Solution Approach 1:
The device is segmented into independent slide members, each with its own elastic tether and track. This segmentation allows each component to be simple and easy to manufacture, while the collective system provides reliable controlled resistance. Each slide member can be produced separately using simple methods, yet together they create a sophisticated resistance mechanism that reliably engages multiple muscle systems.
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 device provides an inexpensive, dependable, and effective means to engage multiple muscle systems, offering a versatile and space-efficient workout solution for indoor use.
Implementation Method 1
two slide members (104, 106) each constrained to slide along frame (102)... each constrained by an elastic tether (108)

AI summary
An exercise device accommodating leg thrust exercises is shown and described. The device provides a flat, nominally planar base or frame on which are mounted two slide members riding in parallel, linear tracks. Each slide is coupled to the frame by an elastic tether. A hand grip bar spans right and left sides of the frame at one end thereof. In use, a person grasps the hand grip bar, and places each foot on one of the slide members. The user then pushes with either one leg or alternatively, with both legs, against the resistance of the elastic tether.
