Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing door-frame exercise apparatuses cause unsightly damage to door trims and pose safety risks due to loose accessories during vigorous use.

Innovation Solution

A body weight exercise assembly with an elongated body featuring a slot or T-slot system that securely attaches to a door frame using fasteners, incorporating a connecting member with a head and tightening mechanism to prevent damage and ensure accessory stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cross bar rests against the outside trim portion of a door frame, then the exercise apparatus can be mounted on the door frame, but the cross bar applies pressure against the trim causing unsightly damage

Engineering Contradiction:

Improvemounting easeVSAvoiddamage to door trim

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a mediator between the exercise apparatus and the door frame trim. The apparatus mounts to the door frame through a mechanism that distributes loads away from the trim portion, preventing direct pressure contact that causes damage while maintaining ease of mounting.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If hooks are used to attach accessories to the cross bar, then accessories can be attached, but during vigorous use the hooks can become disconnected causing falling injuries

Engineering Contradiction:

Improveaccessory attachmentVSAvoidaccessory security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs curved or rounded attachment features instead of sharp hooks. The connecting members have curved geometries that engage with corresponding curved receptacles in the apparatus body, creating a positive mechanical interlock that prevents disconnection during vigorous use while maintaining accessory attachment versatility.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of manufacture

If the exercise apparatus interferes with normal door operation, then the apparatus can be mounted on the door frame, but the door cannot be closed

Engineering Contradiction:

Improvemounting capabilityVSAvoiddoor operation

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent positions the apparatus mounting mechanism in a different spatial dimension relative to the door frame. The apparatus mounts to the vertical or horizontal members of the door frame structure, avoiding interference with the door's movement path while maintaining secure mounting capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
