Laundry Hanger Clamping Gap Structure for Damage-Free Grip
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
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)
Implementation Method 2
The resilient tongue is formed on the back of the bracket part via an arc-like connecting part, which extends at an angle of approximately 90° along a circular path

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.
