Assemblable modular wardrobe made of plastic material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assemblable modular wardrobes made of plastic material face deformation issues due to the weight of items placed on shelves, which can cause deformation or bending of the wardrobe panels.
Innovation Solution
The introduction of an L-shaped support structure that distributes the weight of the shelves onto a reinforcing structure, preventing panel deformation by using cross-members and connecting uprights that form a frame within the modules, allowing for adjustable height and enhanced mechanical resistance through reticular structures and snap-fitting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If shelves are supported by fixed or removable supports positioned on the internal surface of the rear panel and/or side panels, then the wardrobe structure is simple and easy to assemble, but the panels can be deformed or bent under the weight of items placed on the shelves
Solution Approach 1:
The wardrobe is divided into multiple modular units that can be assembled independently. Each module contains its own reinforcing structure with L-shaped supports, allowing the system to be manufactured and assembled in segments without requiring complex integrated reinforcement throughout the entire structure.
Solution Approach 2:
The reinforcing structure introduces a third dimension by placing supports both inside the modules (internal L-shaped supports) and between modules (connecting uprights). This multi-level reinforcement system distributes weight vertically and horizontally, preventing panel deformation while maintaining modular assembly simplicity.
2Strength
If a reinforcing structure with L-shaped supports and connecting uprights is introduced to prevent panel deformation, then the mechanical resistance and stability of the wardrobe are enhanced, but the device complexity increases
Solution Approach 1:
The L-shaped supports combine multiple functions: they reinforce the rear panel, support the shelves, and connect to the connecting uprights. This merging of reinforcement and support functions into a single integrated component reduces the number of separate parts needed, thereby reducing overall structural complexity while maintaining high mechanical resistance.
Solution Approach 2:
The connecting uprights serve multiple purposes: they connect adjacent modules together, provide attachment points for L-shaped supports, and contribute to the overall structural stability. This multi-functionality reduces the need for separate components, simplifying the overall structure while enhancing mechanical resistance.
