Solution Overview

Problem

Existing fitness apparatuses designed for hip thrust exercises are bulky, non-collapsible, and not adequately designed for in-home use, making them difficult to set up, time-consuming, and posing safety risks.

Innovation Solution

A collapsible, adjustable weighted hip thrust exercise apparatus featuring a base frame with an exercise space, an upper body support, and resistance bands attached to the frame, allowing for easy setup and use while providing effective gluteal muscle exercise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional barbell hip thrust setup is used, then effective gluteal muscle exercise is achieved, but the setup is time-consuming and has safety risks

Engineering Contradiction:
ImprovesafetyVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a specialized frame structure with footrest and backrest as intermediary elements between the user and the resistance mechanism. This frame mediates the exercise performance, providing stable positioning and support, thereby eliminating safety risks associated with free barbell handling and reducing setup time through pre-configured geometry.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The frame is pre-configured with fixed geometric relationships between footrest, backrest, and resistance band attachment points. This preliminary arrangement of components eliminates the need for time-consuming setup adjustments during each exercise session, while pre-positioned safety features prevent harmful effects before they occur.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If existing fitness apparatuses are used, then gluteal muscle exercise is possible, but the apparatus are bulky and not suitable for in-home use

Engineering Contradiction:
Improvein-home suitabilityVSAvoidapparatus size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The apparatus is segmented into functional components (frame, footrest, backrest, resistance band system) that can be independently configured. This segmentation allows the device to maintain compact dimensions suitable for home environments while preserving all necessary functions for effective gluteal exercise through proper spatial arrangement of segments.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If adjustable frame is used, then different user sizes are accommodated, but device complexity increases

Engineering Contradiction:
Improveuser size accommodationVSAvoidframe adjustability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Adjustability is implemented locally at specific critical points (footrest position, backrest height, resistance band attachment points) rather than throughout the entire structure. This localized adjustability provides sufficient accommodation for different user sizes and exercise variations while maintaining overall structural simplicity and ease of use.

Inventive Principle:
Principle #3Local quality

AI summary

In various exemplary scenarios, some embodiments of the present invention provide a collapsible, user-friendly weighted hip thrust exercise apparatus. Various embodiments of the present invention may consist of a base frame enclosing an exercise space, with an upper body support attached to one end of the frame. The frame may be adjustable in length and/or width in order to accommodate different users. The upper body support may be configured to provide an elevated back rest for the user. In an illustrative example, the upper body support height may be adjustable to accommodate different users. In an exemplary scenario illustrative of various embodiments' usage, a user may sit down in the exercise space enclosed by the frame with the user's upper-back and arms resting on top of the upper body support, placing his or her feet on top of the frame on the other width side. The apparatus may further feature a central resistance band positioned at the user's hip line, coupled to side handles or multiple attachment points, and detent pins to removably lock the apparatus in place for use.
