Metal Hook Hanger Indicator Block for Visible Size Marking

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hangers with indicator blocks or size markers positioned at the base of the hook make it difficult to read information, especially when garments are compactly grouped together, as the markers are not clearly visible.

Innovation Solution

A hanger design featuring a centrally located upstanding metal hook with a mounting portion at the top, where a separate indicator block is anchored via an eyelet, allowing it to project outward and upward, and equipped with projections for secure attachment, ensuring the block is upright and visible, even when multiple hangers are grouped together.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the indicator block is positioned at the base of the hook, then the structure is simple and stable, but the visibility of the size marker is poor when garments are compactly grouped

Engineering Contradiction:

Improvevisibility of size markerVSAvoidmounting structure complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The indicator block is repositioned from the base of the hook to the top of the hook, changing its spatial dimension and location. This dimensional change allows the size marker to be visible above the garments even when compactly grouped, resolving the visibility issue without requiring complex additional structures.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Instead of placing the indicator block at the base of the hook as in conventional designs, the invention inverts this arrangement by positioning it at the top of the hook. This inversion solves the visibility problem while the eyelet and projection mechanisms maintain structural simplicity and stability.

Inventive Principle:

Principle #13The other way round (Inversion)

2Loss of information

If the indicator block is positioned at the top of the hook for better visibility, then the size marker is clearly visible, but the mounting and removal process becomes more complex

Engineering Contradiction:

Improvevisibility of size markerVSAvoidmounting and removal ease

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The indicator block is designed with nested components including an outer shell, inner block, and movable projection elements that fit within each other. The projection can be inserted through the eyelet from the inside, allowing easy mounting and removal while maintaining top-position visibility.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The projection element is designed to be movable rather than fixed, allowing it to be flexibly inserted through the eyelet for mounting and retracted for removal. This dynamic mechanism simplifies the mounting and removal operations while enabling the indicator block to remain positioned at the top of the hook for optimal visibility.

AI summary

The top portion of a filiform metal hook of a hanger is provided with an eyelet and the indicator block is provided with a protuberance that fits into the eyelet to secure the indicator block on the hook. In one embodiment, the indicator block has two hingedly connected tabs that are snap-fitted together over the mounting portion of the hook. In a second embodiment, the indicator block is of box shape with internal projections that fit into the eyelet of the hook.
