Foldable Rolling Hamper Frame for Heavy Loads and Compact Storage
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 to occupy minimal space, and equipped with rollers for easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If collapsible hampers are used to save space, then storage space is reduced, but they cannot handle heavy laundry loads and lack durability
Solution Approach 1:
The hamper is divided into separate modular components including a base unit with foldable walls, a removable fabric bag, and an optional top frame. This segmentation allows the structural frame to be designed for durability while the fabric bag provides the necessary capacity, and the modular pieces can be stored compactly when disassembled.
2Reliability
If larger hampers with rollers are used to transport heavy laundry, then durability and transport capability are improved, but they occupy too much space for storage
Solution Approach 1:
The hamper incorporates dynamic elements including rollers attached to the base for easy movement when needed, and foldable walls that can collapse flat for compact storage. The fabric bag can be removed and washed separately, adding flexibility to the system's adaptability between transport mode and storage mode.
3Ease of operation
If separate and individual assembled rolling hampers are placed in stores for sale, then product availability is improved, but shelf space requirements become unfeasible
Solution Approach 1:
The hamper components are designed to package into a compact flat configuration that minimizes retail display space requirements. The foldable walls collapse flat, and components can be nested or stacked efficiently on shelves, making retail display feasible while maintaining full functionality when assembled.
4Volume of stationary object
If knock-down design is used to minimize packaging space, then shipping and storage space are reduced, but assembly complexity increases
Solution Approach 1:
The hamper is divided into a small number of clearly defined modules with standardized connection points. The base unit includes pre-attached rollers and foldable walls with clear hinge mechanisms, the fabric bag has integrated corner pockets for frame insertion, and the top frame uses simple removable connectors. This segmentation with standardized interfaces simplifies the assembly process despite the knock-down design.

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.
