Foldable Hamper Frame Assembly for Compact Storage and Heavy Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable hampers for laundry are either not durable enough to handle heavy loads or occupy too much space when assembled, making them impractical for storage and use in apartments and dormitories.
Innovation Solution
A knock-down hamper design featuring a fabric bag and a supporting frame assembly with foldable components, including a base, foldable wall assembly, and top frame, which can be quickly assembled and disassembled for minimal storage space, incorporating U-shaped locking mechanisms and roller caster assemblies for stability and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If collapsible hampers are used to reduce storage space, then storage space is minimized, but durability and load-bearing capacity deteriorate
Solution Approach 1:
The hamper is divided into separate components (base, four walls, top frame) that can be individually packaged flat and quickly assembled together. This segmentation allows the hamper to be stored in minimal space when disassembled while maintaining full structural integrity when assembled for use.
Solution Approach 2:
The hamper transitions from a static assembled structure to a dynamic disassembled state for storage. The design enables easy assembly and disassembly, allowing the hamper to adapt between occupying full volume for use and minimal flat space for storage, while maintaining durability through robust connection mechanisms.
2Reliability
If larger hampers with rollers are used to improve mobility and load capacity, then durability and mobility are improved, but storage space occupied increases
Solution Approach 1:
The frame is segmented into base, walls, and top frame components that can be packaged flat. The rollers are integrated into the base component, ensuring they are included in the compact packaging without increasing the assembled storage footprint.
Solution Approach 2:
The design allows components to nest together in a compact configuration for storage. The walls can be positioned within the base footprint, and the top frame nests accordingly, creating a space-efficient packaged unit that includes all mobility features.
3Area of stationary object
If collapsible hampers are used to minimize storage space, then storage space is minimized, but assembly complexity and time increase
Solution Approach 1:
The hamper is segmented into a base, four walls, and a top frame, with each component designed for simple connection to others. The standardized connection points and mechanisms reduce assembly complexity despite the multi-component nature.
Solution Approach 2:
The components are pre-designed with integrated connection features (slots, tabs, locking mechanisms) that guide proper assembly sequence and reduce the need for complex alignment or adjustment during assembly.
4Area of stationary object
If collapsible hampers are used to reduce storage space, then storage space is minimized, but physical effort required for transport increases
Solution Approach 1:
The rollers are merged with the base component, combining the mobility function with the structural support element. This integration ensures that the hamper can be wheeled when assembled without requiring separate transport mechanisms.
Solution Approach 2:
The hamper transitions between a static stored state and a dynamic transport state. The rollers enable easy movement when assembled, while the compact disassembled form minimizes storage space requirements.

AI summary
A hamper has a fabric bag, and a supporting frame assembly that has a foldable wall assembly, a base and a top frame. The foldable wall assembly has a rear frame, a left frame a right frame. The base has a rear side that is pivotally connected with the bottom side of the rear frame, with the left and right sides of the base removably coupled to the bottom sides of the left frame and the right frame, respectively. The top frame has a rear side that is removably coupled to the top side of the rear frame, with the left and right sides of the top frame removably coupled to the top sides of the left frame and the right frame, respectively. The fabric bag has four side walls, each side wall having a lip extending around the upper edge of each side wall, and four vertical corner sleeve pockets.
