Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resistance training apparatuses fail to provide a compact, unified machine capable of medium to heavy training for chest, back, thighs, calves, shoulders, and arms, often requiring multiple stations and inadequate for optimal weight distribution and movement types.
Innovation Solution
A compact exercise apparatus with a frame, front user bearer assembly, guide means for vertical movement, and compensating support system allowing angular and height adjustments, using a common weight stack and guide rails for both the front assembly and weight stack, enabling versatile exercises with adjustable resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple exercise stations are joined closely together to combine exercise functions, then space utilization is improved, but the apparatus fails to provide heavy training capability for chest, legs, arms, shoulders and back
Solution Approach 1:
The patent creates a single unified apparatus that performs multiple exercise functions including chest, back, leg, arm, and shoulder training. The common resistance device and weight stack serve multiple exercise stations, allowing one machine to replace several separate stations while maintaining heavy training capability through a centralized resistance system.
Solution Approach 2:
The patent merges multiple exercise functions into a single compact station by joining exercise stations closely together and using a common resistance device. The guide means and support system integrate the movement paths of multiple exercises into a unified structure, enabling heavy training across multiple body parts from one location.
2Device complexity
If a common resistance device and weight stack are used for multiple exercise functions, then device compactness is improved, but the apparatus fails to provide optimal positions for training and proper weight distribution
Solution Approach 1:
The patent incorporates adjustable components including height adjustment mechanisms and angular adjustment mechanisms that allow the front assembly to be positioned at different heights and angles. The guide means can be adjusted to accommodate various exercise positions, enabling optimal training postures while maintaining a compact unified structure.
Solution Approach 2:
The patent divides the apparatus into distinct functional segments: a front assembly for user support and exercise positioning, a common resistance device for providing resistance, and a weight stack for load selection. This segmentation allows each component to be optimized independently while maintaining overall compactness and proper weight distribution.
3Adaptability or versatility
If the front assembly is made height adjustable and angularly adjustable to accommodate various exercises, then versatility is improved, but the support system becomes more complex
Solution Approach 1:
The support system is designed to handle multiple adjustment functions through a unified structure. The guide means serves both as a guidance mechanism for vertical movement and as a mounting point for height and angular adjustments. This multi-functional design reduces the need for separate adjustment mechanisms for each degree of freedom.
Solution Approach 2:
The patent introduces angular adjustment as an additional degree of freedom beyond vertical height adjustment. The angular adjustment mechanism allows the front assembly to tilt at different angles, providing versatility for various exercise positions while the support system manages this additional dimension through integrated pivot points and guide structures.

AI summary
An exercise apparatus for exercising multiple body parts includes a frame and a front user bearer assembly which is angularly and height adjustable relative to the frame. The front bearer assembly is mounted to a guide for guiding upward and downward movement of the front bearer assembly. A compensator to ensure that the front assembly travels in a substantially vertical plane during exercise includes a number of support elements, which are pivotally mounted.
