Laundry Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Socks are often lost during washing and drying, requiring users to match them manually, which can lead to unusable pairs.
Innovation Solution
A laundry clip with a pre-torsioned over-center mechanism and water-resistant lining that clips socks together and includes a hooking arrangement for hanging on a washing line, ensuring socks remain paired throughout washing and drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If socks are washed separately without being paired, then washing process is simple, but socks are lost and matching becomes difficult
Solution Approach 1:
The patent combines multiple functions into a single laundry clip device: the clipping mechanism that holds socks together, the over-centre locking arrangement that secures the clip, and the hooking arrangement for hanging. This integration allows socks to be kept paired throughout washing and drying while maintaining simple operation.
Solution Approach 2:
The laundry clip enables preliminary pairing of socks before washing by clipping them together in advance. The over-centre mechanism pre-secures the socks in a paired state, preventing loss during the washing process and eliminating the need for manual matching afterward.
2Reliability
If a clipping mechanism is used to hold socks together, then socks remain paired, but the device structure becomes more complex
Solution Approach 1:
The clipping mechanism is segmented into distinct functional components: the clip member with gripping surfaces for holding socks, the outer arms that provide leverage, and the over-centre locking arrangement. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure manageable and understandable.
Solution Approach 2:
The over-centre locking mechanism is designed to be self-locking once activated. When the clip member is pressed into the closed position, the geometry of the outer arms and locking arrangement automatically maintains the closed state without requiring additional force or complex control systems, reducing operational complexity.
3Strength
If an over-centre clip mechanism is used, then the clip remains securely closed, but it requires pre-torsioning which complicates manufacturing
Solution Approach 1:
The manufacturing process utilizes parameter changes in the metal frame material through pre-torsioning. The metal frame is formed with specific torsional characteristics that allow it to be bent into the over-centre configuration. This pre-torsioning creates the necessary mechanical advantage for the clip to remain securely closed while maintaining ease of manufacture through controlled material deformation.
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 laundry clip effectively keeps socks paired during washing and drying, preventing loss and simplifying the matching process, while also allowing for easy storage or drying.
Implementation Method 1
a pre-torsioned over-centre clip configured for clipping a pair of socks together, the over centre clip including at least a pair of opposed clamping members, the opposed clamping members being relatively movable between an open condition in which socks are receivable between the clamping members; and a closed condition in which socks are conveniently removable from between the clamping members

AI summary
A laundry clip for holding socks together while being washed includes a clipping arrangement and may also have a hooking arrangement. The clipping arrangement may be moved between an open condition and a closed condition. A sock holder comprising a plurality of laundry clips is also described in conjunction with a bag to hold socks therein.
