Hip Thrust Apparatus with Variable Resistance Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise apparatuses for strengthening the gluteus maximus and related muscle groups are either ineffective or uncomfortable, particularly due to the use of heavy weights and large footprints, and lack a compact, portable, and adjustable solution for home use.
Innovation Solution
A compact, low-profile, fully integrated exercise apparatus with a variable resistance transmission system that includes a cross-member with hip/lap cushions and a resistance mechanism, such as constant force springs, allowing for adjustable resistance levels without the need for weights, and featuring a chassis with a foot platform and shoulder/back support for comfortable and effective hip thrust exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional barbell weighted hip thrust exercise is used, then heavy force loads can be applied to strengthen glute muscles, but the barbell applies great pressure to the skin and internal organs causing discomfort and pain
Solution Approach 1:
The patent introduces a padded support structure as an intermediary between the weight and the user's body. The support includes a contoured pad with a recessed portion that cradles the hips, distributing the force load across a larger surface area and reducing pressure concentration on the skin and internal organs, while still transmitting sufficient force to strengthen the glute muscles effectively
2Force
If gym-style weight-stack machines or benches with multiple attachment points are used, then high loading levels can be achieved, but the equipment is not portable and requires large footprint
Solution Approach 1:
The patent extracts the essential function of providing high loading levels from complex gym-style weight-stack machines and large benches. It achieves this by using a simplified design with a portable frame structure that can support substantial weights through a straightforward hip thrust mechanism, eliminating the need for bulky weight stacks and multiple attachment points while maintaining high loading capability
Solution Approach 2:
The patent concentrates the necessary structural support and loading capability in the local area where it is needed - the hip support region. The contoured pad and focused weight distribution system provide high loading levels precisely where required for glute strengthening, without requiring the entire equipment structure to be oversized or overly complex
3Weight of stationary object
If resistance band exercises or bodyweight exercises are used, then the equipment is compact and portable for home use, but the low loading levels render them largely limited in effectiveness
Solution Approach 1:
The patent segments the resistance system into a portable frame structure that can be easily assembled and disassembled for storage, yet when assembled, it provides a stable base for applying high loading levels through weight plates or resistance mechanisms. The contoured pad is also segmented to allow adjustable positioning on the frame, enabling customization for different users and exercise variations
4Ease of operation
If commercial Hip Thruster or BootySprout equipment is used, then hip thrust exercise can be performed with foot platform and back support, but the equipment is heavy and not portable
Solution Approach 1:
The patent employs a dynamic, adjustable frame structure that can be configured in different positions and heights to provide optimal support for hip thrust exercises. The back support and foot platform are positioned to create the correct biomechanical alignment, enhancing exercise comfort and effectiveness. The entire structure is designed to be lightweight enough for portability while maintaining the necessary stability and support during exercise performance

AI summary
An exercise apparatus and method for working the hip muscles, in particular the glute muscle groups. Said exercise apparatus includes a low-profile chassis having a front portion and a rear portion, an elongated cross member having a pair of hip/lap cushions, a foot platform slidably mounted on the chassis, a shoulder/back support mounted on a support frame, a resistance member for loading the muscles of a user and a variable transmission adapted to act as a variable diameter pulley configured to reduce the input force required for a user to overcome the resistance member force.
