Assisted Squat Apparatus with Adjustable Buttocks Pad and Weight Stack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise apparatus for targeting the gluteus muscle group, such as those described in U.S. Pat. No. 9,375,607, lack commercial suitability and have limited resistance, making them unsuitable for diverse user needs and gym use.
Innovation Solution
A manually operated exercise apparatus with a weight stack resistance system and adjustable frame construction, featuring a pivotally attached buttocks support pad, adjustable handgrips, and an angled foot ramp, allowing for customizable user positioning and resistance levels through a cable system, enabling controlled squatting and return motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable apparatus with limited resistance is used, then the device is easier to transport and simpler in structure, but it has limited adaptability for diverse user needs and commercial gym use
Solution Approach 1:
The apparatus incorporates a weight stack system with multiple weight plates that can be selectively stacked to provide varying resistance levels, making the device suitable for users of different strength levels and exercise goals. This multi-functionality allows a single device to serve commercial gym needs while maintaining portability
Solution Approach 2:
The arm assembly includes adjustable components such as the buttocks support pad position and handgrip positions that can be dynamically configured to accommodate users of different heights and body types. This dynamic adjustability enhances versatility without significantly increasing device complexity
2Reliability
If traditional barbell squats are performed, then the exercise effectively targets the gluteus muscles, but it requires high dexterity, balance, and strength to lift and maintain the barbell
Solution Approach 1:
The apparatus introduces a guided arm mechanism with a buttocks support pad and handgrips as intermediaries between the user and the resistance system. This mediator structure provides stability and guidance, eliminating the need for the user to balance a free-weight barbell while still effectively targeting the gluteus muscles through the squatting motion
Solution Approach 2:
The apparatus incorporates a return mechanism with a spring or elastic element that beforehand cushions and assists the user in returning to the upright position after the squatting phase. This reduces the effort required to complete the full range of motion while maintaining exercise effectiveness
3Reliability
If a power cage or Smith machine is used to prevent barbell movement, then proper form is maintained and exercise effectiveness is improved, but the device complexity and space requirements increase
Solution Approach 1:
The invention extracts only the essential form-control function from complex power cages and Smith machines by using a simplified guided arm mechanism. The arm is constrained to move along a predetermined arc by its pivot connection to the frame, providing form control without requiring the elaborate cage structures or vertical guides of traditional machines
Solution Approach 2:
The apparatus integrates multiple functions into nested components: the guided arm mechanism incorporates both the support pad and handgrip positioning functions, while the weight stack system is integrated into the same frame structure. This nesting reduces overall device complexity compared to separate components
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 apparatus provides increased stability, user-specific configuration, and improved ergonomics, allowing for effective gluteus muscle exercise with adjustable resistance, accommodating users of varying heights and enhancing the exercise experience by controlling the squatting and rising motions.
Implementation Method 1
The frame supports a weight stack, which is connected to the arm and biases the arm into a starting position and provides resistance to the squatting exercise motion of the user
Implementation Method 2
The weight stack is adjustable, and is preferably operatively connected to the arm by a cable system

AI summary
An apparatus for a squat exercise comprises a user buttocks pad supported by a pivotally mounted arm for rotation in a vertical plane to allow the user to perform the exercise while in contact with the buttocks pad. The arm length and initial angular position with respect to the horizontal being adjustable. Hand grips are provided for engagement by the user during the exercise. A weight stack is operatively connected to the arm for providing a resistive force as the user squats and an assisting force as the user rises hack to the starting position. A footrest is positioned to maintain the feet of the user to allow the weight of the user to be directed through the heels during the exercise. A base supports a pivot for the arm, as well as the weight stack and footrest.
