Configurable and dismantlable display case system comprising a plastic shelving unit with trays at different levels, and method of assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular shelving units for promotional displays are difficult to configure for larger surfaces, lack interchangeable promotional graphics, and require adhesives for graphic affixation, limiting their re-use and adaptability in various event settings.
Innovation Solution
A modular display system featuring trays with triangular pillars and male-female connectors for horizontal configuration, interchangeable promotional graphics, and integrated LED lighting, allowing for easy assembly, dismantling, and reconfiguration without adhesives, using PVC profiles and PP trays for structural rigidity and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modular shelving units are configured using basic structures with individual trays and housings, then the cabinet cost is reduced and simplicity is improved, but the ability to configure horizontally to cover larger surfaces deteriorates
Solution Approach 1:
The shelving unit is divided into modular components (trays, housings, pillars) that can be independently assembled. Each tray can be connected to adjacent trays through standardized housings at corners, enabling horizontal expansion while maintaining manufacturing simplicity.
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, enables horizontal connection between trays, and accommodates promotional graphics. This multi-functionality allows the same basic structure to achieve both simplicity and configurability.
2Reliability
If promotional graphics are affixed using adhesives, then the graphics are securely attached, but the cabinet re-usability and adaptability for different campaigns deteriorates
Solution Approach 1:
The promotional graphic attachment system is made dynamic and adjustable rather than fixed. Graphics can be installed and removed easily from the housing structures, allowing the cabinet to adapt to different promotional campaigns while maintaining secure attachment during use.
Solution Approach 2:
The cabinet structure is designed to be reusable across multiple campaigns. Promotional graphics can be discarded or replaced while the underlying housing and tray structure is recovered and reused, separating the temporary graphic element from the permanent structural element.
3Adaptability or versatility
If specialized supports for promotional graphics are added to the shelving unit, then the campaign adaptability is improved, but the device complexity and manufacturing cost increases
Solution Approach 1:
The promotional graphic support function is merged with the existing housing structure. The housing that provides structural support for trays also incorporates features for graphic attachment, eliminating the need for separate specialized supports and reducing overall complexity.
Solution Approach 2:
The housing structure is designed to perform multiple functions simultaneously: structural support, connection between trays, and promotional graphic mounting. This multi-functionality adds graphic support capability without requiring additional specialized components.
4Adaptability or versatility
If trays are connected using cables or cords, then horizontal configuration is enabled, but the structural stability and rigidity deteriorates
Solution Approach 1:
The connection method is replaced from flexible cables to rigid mechanical housings with standardized interfaces. The housing structures at tray corners provide rigid mechanical connection points that maintain structural stability while enabling horizontal configuration through precise fitting.

AI summary
A configurable, dismantlable display case system, with supports for promotional graphics, for use as a display cabinet, the constitution thereof being simple and entailing a reduced cost, and with the possibility of changing the configuration of its assembly and the promotional campaign thereon. The modular display system consists generally of a plastic shelving unit, with trays at different levels, linked at their corners by means of pillars consisting of PVC profiles, of a generally triangular shape, which fit adjustably into corresponding housings, one at each corner and on both sides of each tray; short profiles formed by extruded PVC profiles of a more reduced length than the pillar profiles, of a generally triangular shape with rounded corners which slot adjustably into the corresponding housings of the tray, and comprising non-slip ferrules inserted into the profile forming the leg at the area in contact with the floor; and assembly method.
