Integrated Exercise Machine with Bidirectional Fluidic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines are limited in their ability to simultaneously and effectively exercise all major muscle groups, often requiring multiple stations and failing to provide balanced cardiovascular exercise, leading to user boredom and inefficiency in achieving target heart rate zones.
Innovation Solution
A compact exercise machine with five integrated modules, including a rotary torso, abdominal crunch, chest press/seated row, shoulder press/lat. pull, and leg extension/curl, utilizing bidirectional fluidic resistance and pivoted carriers to allow for comprehensive muscle group exercise from a single position, with optional computer-controlled display for personalized routines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional exercise machines use multiple distributed exercise stations with cable and pulley systems, then specific muscle groups can be exercised, but the machine complexity and space requirements increase significantly
Solution Approach 1:
The patent combines multiple exercise modules (rotary torso, abdominal crunch, chest press/seated row, shoulder press/lat pull, leg extension/curl) into a single integrated machine with a common frame and seat, allowing all modules to be operated from one station rather than requiring separate distributed stations
Solution Approach 2:
The exercise machine is designed as a multi-functional device where a single machine provides five different exercise modules that can exercise all major muscle groups, making one machine replace multiple specialized machines
2Force
If unidirectional resistance machines use weight stacks, then resistance is provided, but the resistance is only proportional to weight and inertia without bidirectional capability
Solution Approach 1:
The patent employs bidirectional fluidic resistance mechanisms that dynamically adjust resistance based on the direction of movement, providing optimized resistance curves for both concentric and eccentric phases of exercises, rather than static weight-based resistance
Solution Approach 2:
The exercise modules utilize fluidic resistance systems (hydraulic or pneumatic cylinders) to provide controlled bidirectional resistance, replacing traditional weight stacks and enabling smooth, adjustable resistance in both pushing and pulling directions
3Force
If telescopic hydraulic struts provide bidirectional resistance, then resistance proportional to compression/expansion rate is achieved, but the number of modules is limited and not all major muscle groups are covered
Solution Approach 1:
The patent integrates five different exercise modules (rotary torso, abdominal crunch, chest press/seated row, shoulder press/lat pull, leg extension/curl) into a single machine framework, expanding muscle group coverage beyond the three modules in prior art machines
Solution Approach 2:
The patent adds rotational movement dimensions to the exercise modules, particularly the rotary torso module that rotates about a vertical axis and the abdominal crunch module that moves in a vertical arc, providing multi-planar exercise capabilities
4Adaptability or versatility
If multiple exercise stations are distributed about the machine, then different muscle groups can be targeted, but the user must change positions and the machine requires more space
Solution Approach 1:
All five exercise modules are positioned such that a single user can access and operate all modules from one seated position on the common seat, eliminating the need to stand up or move to different stations between exercises

AI summary
Disclosed is an exercise machine comprising an operating member arranged to be movable in a generally horizontal arc about a generally vertical axis against resistance and in a generally vertical arc about a generally horizontal axis against resistance to provide both rotational reciprocal movement for rotary torso and abdominal crunch exercises. The resistance may be provided by unidirectional adjustable hydraulic struts. An embodiment comprises five separate exercising modules arranged and configured to respectively exercise torso, abdominal, chest, shoulder and leg muscle groups, the muscle group exercising modules being disposed to be operated by a user from a single seated position.
