Radial Swing Squat Rack for Neutral Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The single leg or Bulgarian Squat exercise often results in poor posture, leading to ineffective movements and frequent back injuries due to sustained poor posture during the exercise.
Innovation Solution
A radial swing portable squat rack that allows movement along a primary and secondary axis, maintaining a neutral posture by enabling the user's back leg to move in an arc and the foot to pivot downward, preventing forward leaning and strain on the lower back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary bench or conventional rack is used for Bulgarian squat, then the equipment is simple and stable, but the user cannot maintain neutral posture and risks back injury
Solution Approach 1:
The rack incorporates a swing arm mechanism that allows dynamic movement along an arc path, enabling the floating leg to move naturally with the squat motion rather than being fixed in place. This dynamic adjustment maintains neutral posture throughout the exercise range of motion.
Solution Approach 2:
The invention adds a second axis of movement by allowing the swing arm to pivot, creating an arc-shaped trajectory for the floating leg. This dimensional change enables simultaneous movement in multiple directions, maintaining proper biomechanics while using relatively simple equipment.
2Ease of operation
If the user performs Bulgarian squat with conventional equipment, then the exercise can be performed, but poor posture leads to ineffective movement and back injuries
Solution Approach 1:
The swing arm acts as an intermediary component between the fixed rack structure and the user's floating leg. It mediates the movement by providing an arc-shaped path that guides the leg through proper biomechanical ranges of motion, preventing compensatory postural deviations.
Solution Approach 2:
The equipment changes the movement parameter from linear (conventional fixed position) to arc-shaped, allowing the floating leg to follow a natural trajectory that maintains neutral spine posture throughout the exercise, thereby eliminating the harmful forward-leaning posture.
3Stability of the object's composition
If the floating leg is restricted in movement, then equipment stability is maintained, but the user cannot achieve full range of motion and neutral posture
Solution Approach 1:
The rack is segmented into a fixed base structure and a movable swing arm component. This segmentation allows the stable base to provide support while the swing arm provides adaptive movement, combining stability with range of motion flexibility.
Solution Approach 2:
The swing arm transitions from a static support to a dynamic component that moves with the user's leg through the exercise range. This dynamic element adapts to the user's motion requirements while remaining grounded by the stable base structure.

AI summary
A radial swing portable squat rack is disclosed. When performing the Bulgarian or single leg squat with conventional methods, the users back (or floating) foot remains stationary or has limited forward and downward movement. This device gives optimal movement for the users back (or floating) leg so as to keep the user in a neutral (or upright) posture throughout the movement (Bulgarian or single leg squat). A pivoting foot support, secured by a frame equipped with structural supports facilitates the movement of the floating leg securely during the squat.
