Exercise Arm Spindle With Elastic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise machines for squats, dips, and chins lack the ability to add resistance against the upward motion, making the exercises less strenuous, and existing weight-based solutions are unsafe due to the risk of weights swinging or falling.
Innovation Solution
An exercise arm apparatus with a pivotally attached arm, an arm spindle for weights, and an elastic member that connects to a belt or pin, allowing adjustable resistance and weight addition, ensuring safety and accommodating different user sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If weights are added to a weight belt during exercise, then the exercise intensity increases, but the risk of injury from swinging or falling weights increases
Solution Approach 1:
The patent extracts the weights from the weight belt system and relocates them to a dedicated arm spindle mechanism. This separates the weight function from the belt, allowing weights to be securely mounted on the arm spindle rather than dangling from the belt, thereby eliminating the swinging and falling hazards while preserving the resistance function.
Solution Approach 2:
The arm spindle acts as an intermediary mechanism between the weight and the exerciser. Instead of weights directly attached to the belt causing harmful movement, the spindle provides a controlled interface that allows weights to be safely mounted and rotated with the arm movement, mediating between the weight's gravitational force and the exercise motion.
2Force
If existing squat-dip-chin machines are used, then the exercises can be performed, but the ability to add resistance against upward motion is limited
Solution Approach 1:
The patent implements a dynamic resistance system where the arm spindle can be adjusted during exercise. The arm can be rotated to different angular positions, allowing the exerciser to dynamically change the resistance level by adjusting the arm's angle relative to the weight, thereby providing continuous adaptability in exercise intensity.
Solution Approach 2:
The resistance addition mechanism is segmented into modular components: the arm spindle, the attachable weights, and the pivot mechanism. This segmentation allows for versatile configuration where different weights can be attached to the spindle, and the arm can be positioned at various angles, providing multiple ways to adjust resistance for different exercise intensities.

AI summary
An exercise arm apparatus and method of use. The exercise arm comprises at least one finger, a spindle attached to the finger, and weights sized to reside on the spindle. One end of the exercise arm is rotatably attached at a pivot point to a frame or to a vertical surface; a belt is attached to an opposite end of the exercise arm by means of a belt line. Where the exercise arm is rotatably attached to a frame, dip bars and chin bars are disclosed wherein an exerciser may perform dips and chins. Upward motion by an exerciser wearing the belt is impeded by spindle weights, a belt elastic attached at one end to the belt and at an opposite end to the exercise arm, and/or an elastic member attached at one end to the frame and at an opposite end to the exercise arm.
