Dual-Axis Pull Down Arm for Versatile Latissimus Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines for targeting latissimus dorsi muscles require multiple machines or accessory handles to perform different exercises, necessitating frequent adjustments and setups.
Innovation Solution
A dual-axis arm configuration in a single exercise apparatus allows for three distinct training methods without adjustments, utilizing horizontal and vertical movements of input grips to accommodate different grip positions, ensuring no setup or modification is required between exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate machines or accessory handles are used to perform different latissimus dorsi exercises, then exercise versatility is improved, but device complexity and setup time increase
Solution Approach 1:
The patent applies universality by designing a single exercise machine with a dual-axis arm assembly that can perform multiple latissimus dorsi exercises (vertical pull-downs, horizontal rows, and diagonal pulls) through different grip positions, eliminating the need for multiple separate machines or accessory handles while maintaining full exercise versatility
Solution Approach 2:
The patent merges multiple exercise functions into one unified machine by combining vertical, horizontal, and diagonal movement capabilities in a single dual-axis arm assembly, allowing users to transition between different exercise patterns without changing machines or accessories
2Adaptability or versatility
If accessory handles are switched between exercises, then exercise variety is improved, but ease of operation deteriorates due to frequent adjustments
Solution Approach 1:
The dual-axis arm assembly provides universal functionality for all exercise variations, allowing users to perform different exercises by simply changing grip positions on the same apparatus without needing to switch handles or make adjustments
Solution Approach 2:
The apparatus is pre-configured with multiple grip positions and dual-axis capability before use, allowing users to immediately transition between exercises without setup or modification during their workout routine
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to perform all three training methods in one machine, providing a versatile and efficient workout by varying grip positions to achieve diverse ranges of motion and resistive loads, enhancing exercise variety and convenience.
Implementation Method 1
the input arm assembly being rotatably pivotable around a first linear axis starting from the start motionless position through a generally rearward and downward path of travel under resistance exerted by the resistance mechanism
Implementation Method 2
the input arm assembly being rotatably pivotable around a second linear axis through a generally lateral or side to side path of travel under resistance from the resistance mechanism
Implementation Method 3
under resistance exerted by the resistance mechanism on application of rearwardly or downwardly directed force by the user

AI summary
Apparatus for performing a pull down exercise comprising:a frame,a seat,an input arm assembly interconnected to a resistance mechanism and a manually graspable mechanism disposed vertically above the user's trunk in a start sitting exercise position, the input arm assembly being pivotably mounted on the frame for back and forth travel along a generally forward to rearward direction and along a generally side to side direction orthogonal to the forward to rearward direction,the input arm assembly being rotatably pivotable around a first linear axis and a second linear axis in the respective directions on exertion by the user of a rearwardly downwardly directed force on the manually graspable mechanism.
