Hip Thrust Machine Recoiling Mechanism Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hip thrust exercise methods using free weights pose risks of injury due to weight displacement and improper barbell positioning, which can lead to back damage and discomfort.
Innovation Solution
A hip thrusting exercise machine equipped with a recoiling mechanism, including a lever, pulley, cable, and weight stack, that provides controlled resistance and prevents weights from falling or causing injury, allowing users to perform hip thrusts in a horizontal position safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If free weights are used for hip thrust exercises, then the exercise can be performed with simple equipment, but the risk of injury increases due to weight displacement and improper positioning
Solution Approach 1:
The patent introduces a machine structure as an intermediary between the user and the weight stack. This machine includes a seat, backrest, and guided weight stack system that mediates the interaction, eliminating the need for users to manually position and balance free weights while maintaining exercise effectiveness and reducing injury risk through controlled movement paths
2Force
If a barbell is used for hip thrusts, then resistance can be applied, but the bar may fall off or cause injury to the back and hips
Solution Approach 1:
The machine uses a guided weight stack system with cables and pulleys as an intermediary mechanism to apply resistance force. This replaces the direct contact barbell system, eliminating the harmful factor of the bar falling off or pressing improperly on the user's body while maintaining effective resistance application through the controlled cable-pulley mechanism
Solution Approach 2:
The machine design incorporates safety features that prevent the weight stack from falling or moving uncontrollably. The guided rails and locking mechanisms provide beforehand protection against weight displacement, ensuring that even if a failure occurs, the weight cannot fall off or injure the user's back and hips
3Ease of operation
If bigger plates are used to provide clearance for hip positioning, then the bar can be managed better, but the equipment becomes heavier and more complex
Solution Approach 1:
The machine uses a cable-pulley system as an intermediary to transmit force from the weight stack to the user's hips. This eliminates the need for large clearance plates and complex barbell positioning mechanisms, achieving ease of operation through the simple cable-pulley interface while reducing overall device complexity compared to a adjustable barbell system with large plates

AI summary
A hip thrusting exercise machine is an apparatus that allows a user to safety perform a hip thrusting exercise in a controlled manner. The apparatus includes a backrest, an abdominal brace, a feet brace, an elongated frame, and a recoiling mechanism. The feet brace and the back rest allows the apparatus to properly hold the user's body in place while the user is performing the hip thrusting exercise. The abdominal brace is pressed against by the user's pelvic region in order to perform the hip thrusting exercise. The recoiling mechanism provides the user with physical resistance as the user pushes to raise the abdominal brace from a resting position to a vertically higher position. The coiling mechanism also returns the abdominal brace from the vertically higher position to the resting position so that the user can repeat the hip thrusting exercise.
