Multilayer Absorbent Bag for Heavy Item Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moving heavy items, especially those that leak oils or other fluids, is challenging due to the risk of damage from narrow spaces and potential spills, which can damage floors and other surfaces.
Innovation Solution
A multilayer absorbent bag apparatus with a top and bottom layer of absorbent material, where the layers are attached around the periphery, featuring a zipper for access and webbing straps for securing items, along with a fluid blocking layer to prevent spills and a low coefficient of friction bottom layer for easy dragging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy items are moved directly across floors through narrow spaces, then the moving process can be completed, but damage to floors and surfaces occurs due to dropping or dragging
Solution Approach 1:
A moving bag apparatus serves as an intermediary between the heavy item and the floor surface. The bag encapsulates the item and has a bottom layer with low coefficient of friction that contacts the floor, preventing direct contact between the item and floor. This mediator protects floors from damage while enabling easy movement through narrow spaces.
Solution Approach 2:
The moving bag apparatus uses flexible fabric layers (top layer, bottom layer, and fluid blocking layer) to create a protective enclosure. These flexible thin films conform to the item's shape and allow the bag to be maneuvered through narrow doorways and staircases while protecting the item and surrounding surfaces.
2Ease of operation
If appliances with fluids or debris are moved, then the item can be transported, but spills may occur causing damage to floors and surfaces
Solution Approach 1:
The moving bag apparatus converts the potential harmful effect of fluid spills into a beneficial containment system. The fluid blocking layer (impermeable membrane) prevents fluids and debris from escaping the bag, while the absorbent layers capture any leaks, transforming the hazard into a controlled containment scenario where spills are prevented from damaging floors.
Solution Approach 2:
The multi-layer construction with fluid blocking and absorbent layers provides beforehand protection against fluid spills. Before any spill can occur during transport, the impermeable membrane and absorbent materials are already in place to prevent and contain leaks, ensuring that even if the appliance leaks, the damage is prevented.
3Device complexity
If a simple moving bag is used, then the structure remains simple, but it cannot effectively catch or absorb spills
Solution Approach 1:
The moving bag apparatus uses composite material construction with distinct functional layers: an impermeable membrane layer for fluid blocking, and absorbent fabric layers for capturing spills. This composite structure integrates multiple materials with different properties into a single protective system that maintains reliability while managing complexity through functional specialization.
Solution Approach 2:
The bag is segmented into functional layers with specific roles: top layer for containment, fluid blocking layer for spill prevention, absorbent layers for capturing leaks, and bottom layer for floor protection and low friction movement. This segmentation allows each layer to perform its specific function efficiently, achieving high reliability through specialized components.
4Strength
If a bag with high friction bottom is used, then the bag provides good grip, but it becomes difficult to drag across floors
Solution Approach 1:
The bottom layer of the moving bag apparatus has locally optimized properties with a low coefficient of friction specifically at the floor-contact surface. This local quality modification allows the bag to slide easily across floors during movement, while other parts of the bag maintain sufficient friction for handling and securing the item during transport.
