Assemblable modular wardrobe made of plastic material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assemblable wardrobes made of plastic panels often deform or bend under the weight of items placed on internal shelves due to inadequate support structures.
Innovation Solution
An assemblable modular wardrobe design featuring a reinforcement structure with lateral cross-members, a connection cross-member, and L-shaped supports that distribute the weight to a vertical upright and connection cross-member, preventing panel deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed or removable supports are positioned on the inside surface of the rear panel and/or side panels to sustain shelves, then the wardrobe structure is simplified and easier to manufacture, but the panels can be deformed or bent under the weight of items placed on the shelves
Solution Approach 1:
The support structure is segmented into multiple components: vertical uprights positioned at the front and rear, horizontal cross-members connecting them, and shelf supports attached to the cross-members. This segmentation distributes the load across multiple points rather than concentrating it on the panels, preventing deformation while maintaining manufacturing simplicity.
Solution Approach 2:
The support structure transitions from a two-dimensional arrangement (supports directly on panels) to a three-dimensional framework (vertical uprights extending forward from the rear panel, connected by horizontal cross-members). This adds depth to the support system, creating a spatial framework that distributes loads effectively without increasing panel stress.
2Stability of the object's composition
If a reinforcement structure with vertical uprights and cross-members is implemented to prevent panel deformation, then the strength and stability of the wardrobe is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The vertical uprights serve multiple functions: they provide structural support to prevent panel deformation, serve as mounting points for shelf supports, and act as connection elements for horizontal cross-members. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving enhanced stability.
Solution Approach 2:
The reinforcement structure combines different material properties by using rigid vertical uprights and cross-members (providing structural strength) paired with the existing panel materials. This composite approach creates a hybrid structure where each component contributes its optimal properties, achieving high stability without requiring complete restructuring of the entire wardrobe.

AI summary
The invention relates to a modular wardrobe made of plastic material, comprising an assemblable reinforcement structure (15), where said assemblable reinforcement structure (15) comprises a pair of lateral cross-members (24), where each of the aforementioned lateral cross-members (24) is connectable to a connection cross-member (28) to form a stiffening structure (17) for the wardrobe (10) and where an L-shaped support (23) is further provided for sustaining shelves (61, 62) of the wardrobe (10), said L-shaped support (23) comprising a portion for connecting the connection cross-member (28) to a vertical upright (22) for forming said assemblable structure (15). The provision of the L-shaped support (23) allows one or the other shelf portion (61 or 62) to be selectively removed without having to use an upright for supporting the remaining shelf and hence increasing flexibility when using the wardrobe.
