Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modular cardboard boxes are used for handling and storage, then ease of handling and storage is improved, but mechanical resistance and stability deteriorate
Solution Approach 1:
The display structure is divided into modular components (shelves, columns, connecting elements) that can be independently handled, stored, and assembled. Each shelf unit is a self-contained module with integrated corner columns and connecting elements, allowing easy handling while maintaining structural integrity through the segmented design.
Solution Approach 2:
The invention uses composite construction combining cardboard material with reinforced corner columns and connecting elements. The corner columns act as structural reinforcement points, creating a composite structure that enhances mechanical resistance while maintaining the lightweight cardboard base material for ease of handling.
2Quantity of substance
If modular cardboard boxes are used for storage, then storage efficiency is improved, but stability deteriorates
Solution Approach 1:
The display is segmented into standardized modular units that can be efficiently stacked and stored. Each module has consistent dimensions and connection points, enabling compact storage arrangements while maintaining structural stability through uniform connection geometries across all modules.
Solution Approach 2:
The modular design allows nested storage where smaller display units can be stored within or alongside larger units. The corner columns and connecting elements are designed to nest efficiently, maximizing storage space utilization while preserving the stability of individual modules during storage.
3Ease of manufacture
If simple holding strips are used for assembly, then ease of manufacture is improved, but stability deteriorates
Solution Approach 1:
The connecting elements are segmented into standardized components with predefined connection geometries. This segmentation allows for simple manufacturing processes while ensuring stable connections, as each segment can be independently manufactured and then assembled through standardized interfaces.
Solution Approach 2:
The connecting elements utilize parameter optimization in their geometry and material properties to achieve stable connections through simple assembly processes. The connection parameters (dimensions, shapes, material characteristics) are specifically designed to provide adequate stability while maintaining ease of manufacture.

AI summary
The invention relates to a modular structure for a cardboard tower-like display, made up of shelf modules (a) each of which is made up of a cardboard sheet with a four-sided central area (10) whose corners form incoming vertexes (12) and whose sides are folding and flapping lines with respective flaps thereof; together with straight tubes which feature stud modules (b), with the same cross section than the perimeter tubular edges (11) of each shelf module (a), and connecting elements in the shape of corner studs (c), each of which has a central part (30) with arms (31), (32) and (33) projected into three orthogonal spatial directions which fit into the concurrent ends of the tubular edges (11) of each shelf module (a), and the ends corresponding to the tubes which constitute the stud modules (b).
