Solution Overview
Problem
Existing muscle training devices for domestic use lack the versatility and functionality of gym equipment, limiting the variety of exercises that can be performed, the range of muscle groups that can be targeted, and the ability to measure power exerted during exercises.
Innovation Solution
A muscle training device with a wall-anchored support structure that allows linear displacements in the Cartesian axes X and Y, and rotations in the Y axis, combined with a closed cable system and elastic resistance bands that provide progressive resistance, enabling a wide range of exercises and power measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the device uses a compact structure suitable for domestic use, then the device can be installed in home environments, but the variety of exercises and muscle groups that can be targeted is limited
Solution Approach 1:
The device employs dynamic elements including movable pulleys that can be repositioned along cables, adjustable cable routing, and movable resistance elements that allow the same compact structure to support multiple exercise variations. This dynamic reconfigurability enables a compact device to provide gym-level versatility without requiring large installation space.
2Device complexity
If the device uses elastic resistance bands instead of weights, then the structure can be more compact and easier to install, but the ability to provide progressive resistance and measure power exerted is reduced
Solution Approach 1:
The patent replaces traditional mechanical weight stacks with an elastic resistance system using bands or springs that provide progressive resistance. This substitution maintains structural simplicity while enabling power measurement through sensors that detect the elastic element's deformation and calculate the work done by the user during the exercise.
3Adaptability or versatility
If the device allows movement in multiple directions and rotations, then the range of exercises increases, but the structural complexity and stability requirements increase
Solution Approach 1:
The device uses universal components such as movable pulleys, adjustable cable attachments, and reconfigurable resistance elements that can be positioned to enable various movement patterns including linear displacement in multiple directions and rotation. These multi-functional elements allow a single structure to support diverse exercises without requiring separate mechanisms for each movement type.

AI summary
Muscle training device comprising a support structure (1), pullers (4) that can be moved and operated by a user, a resistant element (2) linked to the support structure (1), which exerts a resistance to the pullers (4) to perform a muscular exercise, fixed pulleys (23), a hoist (24), and a closed cable (3), without free ends, linked to the resistant element (2) and to the support structure (1) through the fixed pulleys (23) and the hoist (24) and operable by means of the pullers (4), such as to allow at least two degrees of freedom of movement in the pullers (4). The support structure (1) is formed by static elements and dynamic elements, and the rotating assembly (16) allows a 360° rotation of the puller (4), the axis of this rotation coinciding with a longitudinal axis of the closed cable (3).
