Solution Overview

Problem

Existing strength training equipment is bulky, heavy, and poses a risk of injury due to weight adjustment, while also occupying excessive space and lacking efficient space utilization.

Innovation Solution

A variable exercise apparatus with a polygonal prismatic main body and sliding, rotating side frames that accommodate and project from the main body, featuring handles adjustable in height and angle, and equipped with a motor and reducer for controlled exercise load, allowing safe and space-efficient muscle workout.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional strength training equipment is used, then exercise load can be controlled, but the equipment is bulky and occupies excessive space

Engineering Contradiction:
Improveexercise load controlVSAvoidarrangement space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The side frames are designed to be nested within the main body part when not in use, with the first side frame accommodated in the main body part and the second side frame symmetrically arranged. This nesting configuration allows the equipment to occupy minimal space during storage while providing full functionality during exercise.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The side frames are configured to rotate with respect to the main body part when drawn out, transitioning from a compact stored position to an extended exercise position. This dynamic transformation enables the equipment to adapt between space-saving storage and functional exercise states.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If traditional strength training equipment is used, then exercise functionality is provided, but the equipment is heavy and difficult to arrange

Engineering Contradiction:
Improveexercise functionalityVSAvoidequipment weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The equipment is divided into a main body part and separable side frames that can be independently positioned. The side frames include handle adjustment pillars and movable handles that can be configured for different exercise types, providing versatility without requiring a single heavy integrated structure.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If weight adjustment is used to control exercise load, then exercise intensity can be controlled, but exposure to injury risk increases

Engineering Contradiction:
Improveexercise intensity controlVSAvoidinjury risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional mechanical weight adjustment system with a driving part that generates exercise load through controlled mechanical movement. The side frames rotate and extend to provide variable resistance through changes in mechanical leverage and position, eliminating the need for discrete weight plates and their associated safety hazards.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If multiple exercise devices are provided for various muscle areas, then comprehensive workout is achieved, but space utilization deteriorates

Engineering Contradiction:
Improvemuscle area coverageVSAvoidspace utilization
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The equipment is designed as a universal exercise station where the side frames can be positioned and configured for different exercise types. The movable handles and adjustable pillars allow the same basic structure to serve multiple muscle groups, replacing the need for separate dedicated devices for each muscle area.

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