Barbell Training Device with Dynamic Support and Guiding Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training devices with supported barbells using wires pose safety concerns during free-weight training, limiting the ability to perform exercises safely and effectively without a spotter.
Innovation Solution
A training device with a frame body, support body, moving means, control means, and state detecting means that guides and controls the barbell's position based on user and barbell state, ensuring safe and solo performance of various free-weight training exercises, using a barbell with a flange and weight equipping portion for precise guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a training device uses wires to support the barbell, then the device can enable solo free-weight training, but the safety of the training is compromised
Solution Approach 1:
The invention removes the wires from the support system and replaces them with a mechanical support body that contacts the barbell directly. The support body includes guiding portions that physically guide the barbell along a predetermined path, eliminating the need for wire-based support and thereby improving safety while maintaining solo training capability.
Solution Approach 2:
The support body acts as an intermediary between the barbell and the user, providing mechanical guidance and support. The guiding portions of the support body mediate the movement of the barbell, ensuring it follows a safe predetermined path while allowing the user to perform exercises independently.
2Reliability
If a training device provides mechanical support for the barbell, then training safety is improved, but the freedom of movement and natural balance engagement are reduced
Solution Approach 1:
The support body is designed to move dynamically along with the barbell rather than being fixed. The support body follows the barbell's movement along a predetermined path, providing guidance while allowing natural motion. This dynamic support maintains safety without overly constraining the user's movement freedom.
Solution Approach 2:
The guiding portions of the support body provide localized guidance at specific points of contact with the barbell, rather than completely constraining the barbell's movement. This localized guidance approach ensures safety at critical points while allowing freedom of movement in other directions.
3Manufacturing precision
If the support body guides the barbell to a predetermined position, then the barbell positioning precision is improved, but the device complexity increases
Solution Approach 1:
The guiding portions of the support body utilize curved surfaces that naturally guide the barbell along a predetermined path through geometry alone. The curved surfaces provide passive guidance without requiring complex active control mechanisms, thereby achieving precise barbell positioning while minimizing device complexity.

AI summary
A training device for strength training is capable of performing through use of a barbell, the training device including: a frame body; a support body configured to support the barbell from below; moving means for moving the support body to ascend and descend along the frame body; control means for controlling the moving means; and state detecting means for detecting a state of the barbell or a user, wherein the control means is configured to control the moving means based on a detection signal detected by the state detecting means. With the training device, various kinds of free-weight training can be solely and safely performed.
