Adjustable Handle Angle Weight Training Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight training apparatuses, such as the hammer type exercise machine, have fixed handle angles, limiting the ability to variably stimulate different muscle parts during exercise.
Innovation Solution
A weight training apparatus with adjustable handle angles, featuring a base frame, chair, hinge-coupled exercise bars, and a torsion angle adjusting mechanism that allows rotation of the exercise bars to change the angle of the handles, enabling stimulation of the outside, center, and inside of the pectoral muscle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle angle is fixed as a single angle, then the device structure is simple, but the ability to variously stimulate muscle parts is limited
Solution Approach 1:
The patent applies the dynamics principle by making the handle angle adjustable rather than fixed. The exercise bar can be rotated to different angular positions around the hinge coupling point, allowing the handle angle to change dynamically based on exercise requirements. This transforms a static structure into a dynamic one that can adapt to different muscle stimulation needs.
Solution Approach 2:
The patent implements parameter changes by allowing the handle angle parameter to be varied. The torsion angle adjusting mechanism enables rotation of the exercise bar to change the angular parameter of the handle, thereby changing the exercise trajectory and muscle stimulation pattern without altering the fundamental device structure.
2Adaptability or versatility
If the handle angle is made adjustable to variously stimulate muscles, then muscle stimulation versatility is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional adjusting mechanism that can achieve multiple handle angles from a single mechanism. The torsion angle adjusting mechanism with hinge coupling allows the exercise bar to assume multiple angular positions, making one mechanism serve multiple functions of stimulating different muscle parts.
Solution Approach 2:
The patent implements segmentation by dividing the exercise bar into segments that can rotate relative to each other at the hinge coupling point. This segmentation allows independent adjustment of the handle angle while maintaining the structural integrity of the overall device.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable handle angles allow for varied muscle stimulation, enhancing the effectiveness of pectoral muscle exercises by allowing the exerciser to target specific muscle areas.
Implementation Method 1
first and second exercise bars hinge-coupled with both sides of a front of the chair to be pushed or pulled forward or backward by the exerciser

AI summary
A weight training equipment includes: a base frame that sits on the ground; a chair provided on the upper portion of the base frame and on which an exercising person may sit; first and second exercise bars that are hinge-coupled to both sides of the front of the chair and formed so as to be pushed or pulled forward and backward by the exercising person; a weight part providing weight and composed of a connection bar, which is connected to one side of the first and second exercise bars, and a weight member formed on the connection bar; and a torsion angle adjusting means for adjusting the torsion angle by rotating the first and second exercise bars.
