Y-Shaped Yoke Exercise Device for Stable Multi-Axis Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices lack versatility and stability when used with weight plates of varying sizes, limiting the range of motion and effectiveness of exercises.
Innovation Solution
The exercise device features a Y-shaped yoke detachably attached to weight plates, coupled with a pivotal tubular receiver that allows for a pole to be extended and moved in various directions, including up and down, pivoted, and rotated, using a pole lock for secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed connection structure is used between weight plates and exercise pole, then structural stability is improved, but versatility and range of motion are reduced
Solution Approach 1:
The connection structure employs a pivotable tubular receiver that allows the exercise pole to pivot and rotate relative to the weight plates. The pivot pin enables controlled movement while maintaining structural connection, providing both stability and range of motion. The pole can be positioned at various angles and secured at different positions along the tubular receiver.
Solution Approach 2:
The connection system is divided into separate functional components: the Y-shaped yoke for weight plate attachment, the pivotable tubular receiver for pole mounting, and the pivot pin for enabling movement. This segmentation allows each component to perform its specific function while working together to provide both stability and versatility.
2Ease of operation
If a simple attachment mechanism is used for weight plates, then ease of operation is improved, but stability and security of attachment are reduced
Solution Approach 1:
The attachment mechanism uses a separate plate pin that extends through the weight plate aperture and is retained by a base washer with a recessed area. This extraction of the fastening function into a dedicated component simplifies the attachment process while ensuring secure connection through the retained base end head.
Solution Approach 2:
The base washer with its recessed area nestedly receives and retains the base end head of the plate pin. This nesting provides a secure attachment mechanism where the recessed area cradles the rounded head, preventing detachment while allowing easy insertion and removal.
3Reliability
If a tight fit is used for pole retention in the receiver, then stability is improved, but ease of operation and range of motion are reduced
Solution Approach 1:
The tubular receiver is designed with a shroud that is larger in diameter than the tube portions, creating an interference fit for pole retention. The pole lock mechanism within the shroud secures the pole while allowing it to pivot and rotate. The pole can be moved up and down, pivoted about the pivot pin, and rotated within the plate aperture to provide a wide range of motion.

AI summary
An exercise device is configured to detachably attached to weight plates and receive a pole that extends to a user end to enable movement of the pole to perform a variety of exercises. The exercise device couples to exercise plates with the shaft of the Y-shaped yoke extending through a plate aperture. A plate pin extends through a plate aperture in a weight plate and is coupled with the Y-shaped yoke. The Y-shaped yoke has a first arm and a second arm that receives a pivot pin therethrough. A pole extends into the shroud of the pivotable tubular receiver and a pole lock secures the pole within the shroud. The pole can then be moved up and down, or pivoted about the pivot pin through the Y-shaped yoke and also rotated within the plate aperture to provide a wide range of motion.
