High-capacity laundry bag convenient for dragging and taking clothes, and foldable for storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry bags lack the ability to efficiently handle large capacities, require cumbersome handling, cannot be dragged, and are inconvenient for storage due to inability to stand independently and difficult folding mechanisms.
Innovation Solution
A high-capacity laundry bag with a bottom pull window, capacity expansion layer, rolling wheels, detachable base, support rings for folding, and connectors for secure locking, along with a trolley and handles for easy movement and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional laundry bags are designed with straps and handles for carrying, then they can be carried by hand, but they cannot be dragged and require cumbersome handling when containing many clothes
Solution Approach 1:
The patent transforms the static carrying method (straps and handles) into a dynamic dragging method by equipping the base with rolling wheels. This allows the laundry bag to adapt its movement mode based on load conditions - can be carried by hand when empty or lightly loaded, and dragged when heavily loaded, optimizing ease of operation across different usage scenarios
2Quantity of substance
If conventional laundry bags are filled with many clothes, then capacity is increased, but it becomes necessary to take out all clothes at the upper end to access clothes at the bottom
Solution Approach 1:
The patent divides the single large cavity into two accessible regions: the upper main cavity and the lower pull window. This segmentation allows users to access clothes at the bottom through the pull window without removing clothes from the upper end, maintaining high capacity while improving operational convenience for retrieving items
3Ease of manufacture
If conventional laundry bags are made with simple cavity structures, then manufacturing is simple, but they cannot stand on their own when empty
Solution Approach 1:
The support rings provide dynamic structural support that adapts to the bag's state: when empty, they maintain the bag's shape and enable it to stand independently; when loaded, they provide internal reinforcement. This maintains manufacturing simplicity while achieving independent standing capability through the strategic placement of rigid circular support elements
4Adaptability or versatility
If conventional laundry bags are delivered by manufacturers or stored temporarily, then they need to be folded for storage, but there is no efficient folding mechanism
Solution Approach 1:
The support rings are pre-positioned along the sidewalls at specific intervals, creating predetermined folding points. When folding is needed, the sidewalls naturally fold at these pre-positioned ring locations, making the folding process quick and intuitive without requiring complex mechanisms or significant user effort
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
Enables convenient dragging and storage of large capacities, independent standing when empty, and efficient folding, enhancing usability and storage convenience.
Implementation Method 1
rolling wheels capable of supporting and moving the bag body, disposed at the bottom of the bag body
Implementation Method 2
a first hook-and-loop fastener disposed at the base, and a second hook-and-loop fastener disposed at the bottom of the bag body correspondingly to the first hook-and-loop fastener
Implementation Method 3
closure of the capacity expansion layer is performed through an elastic rope
