Adjustable Spring Tower for Progressive Resistance Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Pilates exercise equipment, such as the Pilates Reformer and Tower, fail to provide sufficient progressive resistance for varying strength levels and muscle groups, leading to inadequate strength training and inefficient exercise technique, particularly when used from non-standing positions, as they often require additional springs and lack adjustable tension throughout the full range of motion.
Innovation Solution
The Dual Balance Adjustable Spring Tower features a vertically adjustable and movable spring carriage with detachable steel springs, dual cable and pulley linkage systems, and a tilt platform, allowing for customizable resistance distribution and real-time biofeedback, enabling equal resistance for both limbs and accommodating different strength levels and body positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Pilates equipment uses fixed spring resistance, then the equipment structure is simple, but it fails to provide progressive resistance for varying strength levels
Solution Approach 1:
The spring carriage is made movable and adjustable along the tower frame, allowing users to dynamically change spring tension and resistance levels during exercise. This transforms the fixed resistance system into a dynamic one that adapts to varying strength levels and exercise phases.
Solution Approach 2:
The resistance system is segmented into multiple detachable steel springs that can be independently selected and combined. Users can attach or detach springs to create progressive resistance levels, breaking the monolithic resistance system into modular components.
2Reliability
If conventional Pilates Tower uses single spring attachment point, then the device is simple, but it cannot provide continuous tension throughout full range of motion
Solution Approach 1:
The spring carriage moves dynamically along the tower frame to maintain optimal spring tension throughout the full range of motion. This ensures continuous effective tension on the exercise cables regardless of the user's position or exercise phase.
Solution Approach 2:
The spring carriage acts as an intermediary mechanism between the fixed spring attachment and the moving exercise cables. It mediates the tension transmission to ensure continuous force application throughout the exercise range.
3Adaptability or versatility
If conventional equipment requires multiple springs for different resistance levels, then resistance variety is achieved, but device complexity and space requirements increase
Solution Approach 1:
The resistance system is divided into multiple detachable spring modules that can be selectively attached to the spring carriage. Users can combine different spring modules to create various resistance levels, reducing the need for multiple complete spring sets.
Solution Approach 2:
The spring carriage serves multiple functions: it holds springs, adjusts tension, and moves along the tower frame. This multi-functional design consolidates what would otherwise require separate mechanisms into a single integrated component.
4Adaptability or versatility
If Pilates exercises are performed from non-standing positions, then equipment stability is maintained, but real-life functional strength transfer is reduced
Solution Approach 1:
The spring carriage and cable system are designed to accommodate dynamic body positions including standing exercises. The movable carriage adjusts to maintain proper tension and alignment regardless of whether the user is standing, sitting, or lying down.
Solution Approach 2:
The dual cable system with separate carriages for each side allows asymmetric exercise patterns that mimic real-life activities. Users can independently train each limb while maintaining proper form, even in standing positions that better represent functional movements.

AI summary
The present invention pertains to a spring resistance exercise machine including an adjustable spring carriage and anchor housing and having cable and pulley linkage assemblies attached to a plurality of springs, or other resistance sources. Each cable and pulley linkage assembly, which is independent of the other(s), can be used unilaterally (by one arm or one leg at a time) or bilaterally (by both arms or both legs at a time) during exercise resistance training (that is, training in which both limbs of a pair are used to simultaneously pull a certain resistance).
