Solution Overview

Problem

Single-purpose exercise machines, such as leg press and hip thrust machines, require significant floor space, limiting the availability of exercises in smaller gyms, and there is no combined machine that integrates both functionalities.

Innovation Solution

A combined leg press and hip thrust exercise machine with an adjustable exercise bed, comprising an adjustable backrest and a lockable, pivoting seat, allows conversion between leg press and hip thrust configurations using an incline adjustment mechanism and footpad angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If single-purpose exercise machines are used, then the machine structure is simple and easy to manufacture, but the floor space required is large

Engineering Contradiction:

Improvemachine structure simplicityVSAvoidfloor space

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The exercise machine is designed with a multi-functional seat assembly that can be positioned in different configurations to perform both leg press and hip thrust exercises. The seat can be locked in a first position for leg press exercises and moved to a second position for hip thrust exercises, allowing a single machine to replace what would traditionally require two separate machines, thereby reducing floor space while maintaining functional simplicity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The machine incorporates a dynamic seat assembly with adjustable positioning mechanisms that allow the seat to be moved between different fixed positions. This dynamic adaptability enables the same structural components to serve multiple exercise functions, optimizing space utilization without compromising the ease of manufacture through standardized mechanical components

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple single-purpose machines are provided, then each machine can be optimized for its specific function, but the floor space and gym area are reduced

Engineering Contradiction:

Improveexercise function rangeVSAvoidfloor space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The exercise machine integrates two distinct exercise functions (leg press and hip thrust) into a single device through a multi-position seat assembly. The weight platform remains stationary while the seat assembly can be locked in different positions to accommodate different exercise types, providing versatility without requiring multiple separate machines and thus preserving floor space

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The machine is segmented into functionally independent components: a stationary weight platform and a movable seat assembly. This segmentation allows the seat to be independently positioned for different exercises while the weight platform remains fixed, enabling multiple exercise functions in one machine without compromising the structural integrity or requiring additional floor space

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the seat is made movable and adjustable, then the machine can perform multiple exercises, but the device complexity increases

Engineering Contradiction:

Improveexercise configuration flexibilityVSAvoidadjustable components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seat assembly is designed with movable and adjustable components that allow it to be positioned in different fixed locations along the machine frame. The seat can be moved between a first position for leg press exercises and a second position for hip thrust exercises, with locking mechanisms to secure it in place. This dynamic positioning capability provides exercise versatility while using straightforward mechanical components that do not significantly increase device complexity

Inventive Principle:

Principle #15Dynamics

4Area of stationary object

If a combined machine is designed, then floor space is saved, but the ease of operation and setup changes increase

Engineering Contradiction:

Improvefloor spaceVSAvoidmachine configuration

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The seat assembly is pre-equipped with positioning mechanisms and locking features that allow users to quickly switch between exercise configurations. The design anticipates the need for configuration changes and provides intuitive, pre-planned adjustment mechanisms, making the transition between leg press and hip thrust modes straightforward and reducing the operational complexity despite the multi-functional capability

AI summary

An exercise machine that combines the functionality of a leg press exercise machine with the functionality of a hip thrust exercise machine in a single machine. In an embodiment, the exercise machine comprises an adjustable exercise bed comprising an adjustable backrest and a lockable, pivoting seat; a weight plate holder; a footpad having different angles for leg presses and hip thrusts; and an incline adjustment mechanism. The exercise machine can be converted from a leg press machine to a hip thrust machine by changing the position and settings of the adjustable backrest and lockable, pivoting seat.
