Solution Overview

Problem

Existing laundry hangers with resilient tongues often damage or deform clothing due to uneven clamping gaps and projections, which can lead to unsightly wavy structures and difficulty in accommodating items of varying sizes.

Innovation Solution

A laundry hanger with a clamping gap of constant width and stepped design, featuring an elastic tongue and abutment tongues, ensures even pressure distribution and prevents displacement of items, allowing for secure holding of different-sized garments without damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If projections are added to the tongue or back surface to prevent straps from slipping out, then the anti-slip capability is improved, but the textile structure is damaged and deformed due to the wavy gap course

Engineering Contradiction:
Improveanti-slip capabilityVSAvoidtextile damage and deformation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a hook as an intermediary element that protrudes into the interior of the arc-like connecting part to fix the carrier in the clamping gap, replacing the harmful projections with a benign fixing mechanism that does not damage textiles

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the geometry of the clamping gap from a straight or wavy course to a stepped course with at least one gradation, maintaining constant width while creating discrete clamping areas that prevent slipping without damaging the textile structure

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If a straight clamping gap is used, then the textile structure is not damaged, but items of different sizes cannot be securely held due to lack of discrete clamping areas

Engineering Contradiction:
Improvetextile damageVSAvoidaccommodation of different sizes
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent segments the clamping gap into multiple discrete clamping areas through stepped gradations, creating distinct zones that can accommodate items of different sizes while maintaining the integrity of the textile structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by creating different gap sections at different levels with a step in between, where each section can be optimized for specific item sizes while the overall structure remains simple and non-damaging

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the clamping gap width varies significantly, then discrete clamping areas are created for different sizes, but the carrier is excessively squeezed and damaged

Engineering Contradiction:
Improvediscrete clamping areasVSAvoidcarrier damage
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the positional parameter of the clamping gap by introducing stepped gradations in vertical position rather than width variation, creating discrete clamping areas at different levels while maintaining constant width to prevent excessive squeezing

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The stepped clamping gap design prevents excessive squeezing and deformation of clothing, securely holds items of various sizes, and reduces the risk of incorrect operation, ensuring reliable and damage-free hanging.

Implementation Method 1

a resilient tongue (5) which forms a clamping gap (9) between itself and the back (4) of the hanger part (3)

AI summary

The laundry handle (1) is made of plastic and has handle units (3,3') extending itself to both sides of a hook (2), where a springy tongue (5) is provided on back of each handle unit. The clamping gap has a constant width between the tongue and the opposite surface of the back.
