Solution Overview

Problem

Conventional exercise devices are large and limited to training a single muscle group, making them unsuitable for home use and requiring multiple devices for varied workouts, which is costly and impractical for average users.

Innovation Solution

A portable exercise device with a compact design featuring vertically arranged pulley and fan wheel assemblies, adjustable resistance via magnet and fan blades, and a wall-hanging mechanism, allowing users to train different muscle groups by adjusting the device's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional exercise devices are used, then training effectiveness for specific muscle groups is improved, but device size and space requirements increase

Engineering Contradiction:
Improvetraining effectivenessVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple pulley assemblies with different training functions into a single integrated exercise device. The first and second pulley assemblies are mounted on the same base disc, allowing users to access multiple muscle group training capabilities (back, thighs, calves, glutes, biceps, triceps, superior spines, infraspinalis, subscapularis) without requiring separate devices for each function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The exercise device is designed with universal applicability for training various muscle groups through different pulley assemblies. By providing multiple rope configurations and pulley arrangements on a single device, it serves multiple training purposes that would otherwise require several separate specialized devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple exercise devices are purchased to train different muscle groups, then training versatility is improved, but cost increases

Engineering Contradiction:
Improvetraining versatilityVSAvoiddevice quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent creates a single exercise device that performs multiple training functions through different pulley assemblies. The first pulley assembly trains back, thighs, calves, and glutes, while the second pulley assembly trains biceps, triceps, superior spines, infraspinalis, and subscapularis, replacing the need for multiple specialized devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple training functions are merged into one device by mounting different pulley assemblies on a common base disc structure, allowing users to achieve comprehensive muscle group training with a single investment rather than purchasing multiple separate devices.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional rowing machines are used, then training function is improved, but portability and ease of movement deteriorate

Engineering Contradiction:
Improvetraining functionVSAvoidportability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The exercise device is designed as a modular system with a base disc and separately mountable pulley assemblies. This segmented structure allows the device to be disassembled and reconfigured, improving portability and ease of movement while maintaining complete training functionality when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pulley assemblies are designed to be movable and reconfigurable on the base disc, allowing users to adjust the device configuration for different training needs and facilitating easier transport and storage compared to fixed conventional rowing machines.

Inventive Principle:
Principle #15Dynamics

AI summary

A portable exercise device provided includes: a base disc, two pulley assemblies, a support plate, and a fan wheel assembly. A support plate is disposed on the base disc, the two pulley assemblies are provided on the base disc, and the fan wheel assembly is provided on the support plate, so that the fan wheel assembly and the two pulley assemblies are vertically arranged on top of each other, thereby reducing the overall volume. More preferably, because the volume is reduced, the user can arbitrarily move and hang the portable exercise device at the desired position, and because the portable exercise device of the invention can be hung at different positions, which allows the user to train different muscles according to the different positions.
