Exercise Hinge Mechanism for Tangling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jump ropes often tangle or kink due to their fixed connection, limiting motion and making it difficult to track rotations accurately, which affects user performance and data recording.
Innovation Solution
A hinge system with a multi-axis mechanism that allows 360-degree rotational freedom and includes a sensor assembly for tracking rotations, preventing tangling and enabling accurate recording of exercise data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rope is fixed to the handles, then the connection is stable, but the rope tangles or kinks due to rotation
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed rigid connection with a hinge mechanism that allows dynamic movement. The hinge enables the rope to rotate and adjust its position freely, transforming the static fixed connection into a dynamic adaptive connection that prevents tangling and kinking while maintaining stable attachment to the handles.
2Reliability
If the rope is fixed to the handles, then the connection is stable, but the rotation is limited
Solution Approach 1:
The hinge mechanism transforms the static fixed connection into a dynamic system that provides both stability and rotational freedom. The hinge allows multi-axis rotation while maintaining secure attachment, enabling the rope to adapt to various rotation angles and exercise movements.
Solution Approach 2:
The patent applies dimensionality change by introducing multi-axis rotational capability through the hinge mechanism. Instead of limited single-axis rotation, the hinge enables rotation in multiple dimensions, allowing the rope to move freely in various directions while remaining securely connected to the handles.
3Device complexity
If a fixed connection is used, then the structure is simple, but accurate rotation tracking is difficult
Solution Approach 1:
The patent applies the feedback principle by incorporating a sensor assembly that detects rotation movements and provides data feedback. The sensor tracks the rotational movements of the hinge mechanism, enabling accurate measurement and recording of exercise repetitions while maintaining a relatively simple overall structure.

AI summary
A system includes a handle with a hinge mechanism at a first end, the hinge mechanism including a lower hinge portion and an upper hinge portion rotatably coupled together. The handle also includes a rotary mechanism positioned at the first end and coupled to the lower hinge portion to enable circumferential movement of the lower end portion about a longitudinal axis of the handle. Additionally, a sensor arrangement is positioned within a body of the handle, the sensor arrangement measuring a number of rotations of the rotary mechanism about the longitudinal axis of the handle.
