Pivoting-Seat Leg Press and Hip Thrust Machine Conversion
Find Innovative SolutionsGenerate Solutions
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
An exercise machine that combines the functionalities of a leg press and hip thrust machine, featuring an adjustable exercise bed with a lockable, pivoting seat and adjustable backrest, allowing conversion between leg press and hip thrust configurations through positional changes and settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-purpose exercise machines are provided, then a wide range of exercises can be offered, but floor space is consumed
Solution Approach 1:
The patent combines a leg press machine and a hip thrust machine into a single integrated exercise machine. The leg press mechanism and hip thrust mechanism share common structural elements including the frame, weight stack, and exercise bed, allowing both exercises to be performed on one machine rather than requiring separate dedicated machines for each exercise type
Solution Approach 2:
The exercise machine is designed with multi-functional capabilities where the exercise bed can serve dual purposes: as a leg press platform when positioned in the lowered configuration and as a hip thrust bench when positioned in the raised configuration. This universal design allows a single machine to replace multiple single-purpose machines
2Device complexity
If single-purpose exercise machines are used, then each machine is simple in design, but floor space is required for each machine
Solution Approach 1:
The patent integrates two exercise functions into one machine structure, combining the leg press and hip thrust mechanisms while sharing common components such as the frame, weight stack, and exercise bed, thereby reducing the number of machines needed without excessive complexity
3Adaptability or versatility
If an adjustable exercise bed is used for conversion between exercises, then versatility is improved, but device complexity increases
Solution Approach 1:
The exercise bed is designed with dynamic adjustability, allowing it to pivot between a lowered position for leg presses and a raised position for hip thrusts. This dynamic configuration is achieved through a pivot mechanism that enables the bed to assume different angular positions, providing exercise versatility without requiring completely separate machines
4Adaptability or versatility
If a lockable pivoting seat is implemented, then exercise conversion is enabled, but ease of operation is reduced
Solution Approach 1:
The seat is designed with pivoting capability that allows it to move between locked positions corresponding to different exercise configurations. The pivot mechanism enables the seat to be positioned for either leg press or hip thrust exercises, providing adaptability while maintaining operational simplicity through straightforward positioning

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.
