Abdominal Exercise Equipment with Multi-Directional Contact Arms

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional abdominal exercise equipment lacks components that allow users to move their bodies in a targeted and efficient manner, specifically failing to provide independent contact arms that can move in four different directions, limiting effective engagement of abdominal muscles.

Innovation Solution

The equipment includes a rest pad slidably coupled with a first rail, a foot grip with a second rail, and three contact arms slidably coupled with a frame along different directions, allowing users to securely position their body and engage their abdominal muscles by lifting to contact the arms in various directions, with the second direction being perpendicular to the first, the third direction at a 60-degree oblique angle, and the fourth direction perpendicular to the first.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional abdominal exercise equipment is used, then the structure is simple, but the user cannot move the body in a targeted and efficient manner to engage abdominal muscles

Engineering Contradiction:

Improvetargeted body movementVSAvoidequipment structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The equipment is divided into multiple independent movable components: rest pad on first rail, foot grip on second rail, and three contact arms on the frame. Each component can move independently along its designated rail, allowing segmented and targeted body positioning and engagement of different abdominal muscle groups.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

All major components (rest pad, foot grip, contact arms) are designed to be movable rather than fixed. The rest pad slides along the first rail, the foot grip slides along the second rail, and each contact arm slides along its respective rail on the frame, enabling dynamic adjustment and multi-directional movement for comprehensive abdominal exercise.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the equipment includes three independent contact arms that can move in four different directions, then the effectiveness of abdominal muscle engagement is improved, but the device complexity increases

Engineering Contradiction:

Improvemulti-directional contact arm movementVSAvoidnumber of movable components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame structure serves multiple functions: it supports all three contact arms, provides the mounting structure for their rails, and acts as the central structural element connecting to the rest pad assembly. This multi-functional design reduces the need for additional separate components despite the complexity of having three independently movable contact arms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The contact arms are configured to move in multiple directions (four different directions total) along rails mounted on the frame. This multi-dimensional movement capability allows the contact arms to reach various positions and angles, providing versatile exercise options without requiring multiple separate equipment pieces.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An abdominal exercise equipment comprises a rest pad, a foot grip, a frame, and three contact arms. The rest pad is disposed in a horizontal direction and the foot grip slides up and down perpendicular to the rest pad. A frame moves at an oblique angle to the rest pad and three contact arms are slidably coupled with the frame and provide targets for a user to contact using his/her hands.
