Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing garment hangers with loop structures lack a mechanism to securely fix an additional hanger at a stationary position, allowing it to rotate freely when force is applied.

Innovation Solution

A hanger with a dependent loop that includes nodules on its inside surfaces, which serve as a securing mechanism to attach and secure an accessory hanger, using a combination of holes and attaching plates with nodules or pegs for a stable attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a loop structure is used to hang an additional hanger, then the hanger can support another hanging garment, but the additional hanger can rotate freely within the loop and cannot be fixed at a stationary position

Engineering Contradiction:

Improveability to hang additional garmentsVSAvoidposition stability of additional hanger

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

A securing mechanism acts as an intermediary between the loop structure and the additional hanger. This mechanism includes a securing element that engages with the loop to prevent rotation, while still allowing the hanger to be hung and removed. The intermediary component resolves the contradiction by providing both the adaptability to hang additional garments and the stability to fix them at a stationary position.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The securing mechanism transitions from a static loop structure to a dynamic system that can adapt between different states: allowing the additional hanger to be hung, securing it to prevent rotation, and allowing removal. This dynamic capability enables the structure to provide both versatility and stability at different operational stages.

Inventive Principle:

Principle #15Dynamics

2Shape

If a coordinated loop structure is used to keep the additional hanger parallel to the top hanger, then the hangers maintain relative positioning, but the additional hanger is loosely attached and can still be rotated freely when force is applied

Engineering Contradiction:

Improverelative positioning of hangersVSAvoidattachment security

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The securing mechanism serves as an intermediary that strengthens the attachment between the additional hanger and the loop structure. It maintains the coordinated positioning while eliminating the loose attachment problem by providing a positive locking engagement that prevents rotation even when force is applied.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The securing element may utilize curved or spherical geometry to engage with corresponding features on the loop structure, creating a reliable mechanical interlock. This curved engagement provides both the positioning function and the security against rotational forces.

Inventive Principle:

Principle #14Spheroidality (Curvature)
