Laundry Anchor Structure for Preventing Bedding Twist and Wadding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large laundry items such as bedding and long-sleeve shirts often twist, tangle, or wad during washing and drying, leading to inefficient cleaning and drying, appliance imbalance, and increased wear-and-tear, with existing methods providing conflicting and ineffective solutions.
Innovation Solution
A laundry device with a center base and attachment system that secures multiple corners or points of large laundry items, using male and female elements to prevent twisting, tangling, and wadding, and includes materials that withstand various temperatures and laundry agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large laundry items are laundered in washing machine, then cleaning function is achieved, but articles twist, tangle, ball and wad preventing proper cleaning and drying
Solution Approach 1:
The device divides the large laundry item into multiple secured sections by attaching corners to the base structure, preventing the item from moving as a single tangled mass during washing and drying cycles
Solution Approach 2:
The device pre-positions and secures the laundry item corners to the base before the washing and drying processes begin, preventing twisting and tangling from occurring in the first place rather than correcting them afterward
2Reliability
If large articles are secured to prevent twisting and tangling, then article stability is improved, but device complexity increases
Solution Approach 1:
The base structure serves multiple functions simultaneously: it provides structural support, anchors attachment points for laundry items, and maintains load balance in the washing machine, reducing the need for separate components
Solution Approach 2:
The device introduces a simple base structure as an intermediary between the laundry item and the washing machine drum, providing a stable anchoring point without requiring complex mechanisms or modifications to the existing appliance
3Reliability
If laundry device with attachment system is used, then article stability is improved, but ease of operation decreases
Solution Approach 1:
The device allows the laundry item to secure itself to the base through self-attaching mechanisms at the corners, reducing the need for manual manipulation and complex loading procedures by the user

AI summary
Systems and methods for attaching large articles of bedding such as bed sheets, blankets, duvet covers, comforters, and quilts, as well as other machine-washable large items such as sleeping bags, tablecloths, shower curtains, and shower curtain liners, in order to prevent or greatly reduce said articles from twisting, tangling, balling and/or wadding either independently or with each other in either or both the automatic washing machine or automatic clothes dryer. Exemplary fabric securing devices include a rigid base having keyholes and slit-holes, and flexible straps or tongues having a hollow post to engage a base keyhole and a crescent-shaped beveled edge to engage a base slit-hole.
