Solution Overview

Problem

Existing strength training devices with electromechanical components often have an arbitrary arrangement of control and drive components, leading to oversized supporting structures, increased vibration, weight, and costs, with limited installation space and poor maintainability.

Innovation Solution

A device body with spatially separated drive and control components, where the drive arrangement is reinforced only in areas supporting training forces, and the control components are positioned to manage leverage forces and moments, allowing for a standardized design that accommodates multiple strength training devices with two possible training shaft positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If control components and drive components are arranged on different mounting components in an arbitrary manner, then the strength training device can be assembled, but the supporting components become oversized, increasing device weight and vibration

Engineering Contradiction:

Improveassembly flexibilityVSAvoiddevice body weight

Core Design Contradiction:

Ease of manufactureVSWeight of stationary object

Solution Approach 1:

The device body is segmented into a drive component mounting component and a control component mounting component, which are spatially separated and functionally independent. This segmentation allows each component to be optimized for its specific function, preventing oversized supporting structures while maintaining assembly flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control components are extracted from the drive component mounting component and placed on a separate control component mounting component. This extraction eliminates the need for the supporting components to be oversized, reducing device weight and vibration while preserving assembly flexibility.

Inventive Principle:

Principle #2Taking out (Extraction)

2Device complexity

If control components and drive components are arranged on different mounting components, then component functions are separated, but the installation space in the device body becomes limited and tailored to specific positions

Engineering Contradiction:

Improvecomponent arrangement simplicityVSAvoidinstallation space flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The drive component mounting component and control component mounting component are designed with universal features that allow them to be adapted to various installation spaces and configurations. This universality enables the same component design to serve multiple functions and accommodate different spatial arrangements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting components are designed with dynamic adaptability, allowing the position and orientation of control components relative to drive components to be adjusted based on available installation space. This dynamic design maintains component arrangement simplicity while providing installation space flexibility.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If massive vertical component stands are used to support control and drive components, then structural stability is achieved, but the design requires oversized supporting components that increase costs and reduce maintainability

Engineering Contradiction:

Improvestructural stabilityVSAvoidcomponent maintainability

Core Design Contradiction:

Stability of the object's compositionVSEase of repair

Solution Approach 1:

The mounting components are segmented into separate drive component mounting and control component mounting units, each providing structural stability for its specific components. This segmentation reduces the need for massive supporting structures while improving maintainability through localized access to individual components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each mounting component is designed with local quality optimization, providing sufficient structural stability only where needed for the specific components it supports. This localized approach reduces overall material usage and improves maintainability compared to universal massive supports.

Inventive Principle:

Principle #3Local quality
