Modular display case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display cases face challenges in manufacturing efficiency and user access, as they often require disassembly to add or remove items and have issues with hiding and evenly distributing light sources, which complicates the integration of internal lighting.
Innovation Solution
A modular display case design featuring A-shaped acrylic inner frame panels connected by spacers and fasteners, with a removable front panel and integrated LED light strip within the base, allowing for easy access and even illumination through diffuser panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front panel is mechanically attached to the sides through hinges, then the display case structure is stable, but the front panel cannot be entirely removed without disassembling the hinges
Solution Approach 1:
The display case is divided into separable modules: the front panel is detached from the hinge assembly and connected separately to the display chamber using screw posts. This segmentation allows the front panel to be easily removed and reattached without disassembling structural components, resolving the contradiction between ease of access and structural stability.
Solution Approach 2:
The hinge mechanism is extracted and replaced with a simpler connection system. The front panel is taken out from the traditional hinged configuration and reconnected directly to the display chamber using removable screw posts, eliminating the complexity of hinge assembly while maintaining structural integrity.
2Ease of operation
If screw fasteners extend through the front panel to connect inner panels, then the structural connection is secure, but the screws must be removed to access the display compartment
Solution Approach 1:
The fastening system is segmented into two functional parts: permanent screw posts that remain attached to the display chamber providing structural support, and removable front panels that connect to these posts. This allows the display compartment to be accessed by simply detaching the front panel without removing structural fasteners, resolving the contradiction between secure connection and ease of access.
Solution Approach 2:
The fastening system transitions from a static all-or-nothing connection to a dynamic partial connection. The screw posts remain permanently fixed to the display chamber, while the front panel connection is made reversible, allowing the front panel to be easily removed and reattached without affecting the structural integrity of the remaining assembly.
3Illumination intensity
If light sources are placed within the display case, then the illumination is improved, but hiding the light source and distributing light evenly becomes difficult
Solution Approach 1:
A diffuser panel is introduced as an intermediary between the LED light strip and the display chamber. The diffuser evenly distributes the light from the LED strip across the display area while concealing the light source, resolving the contradiction between providing effective illumination and hiding the light source with even distribution.
Solution Approach 2:
The base of the display case is merged with the light housing structure. The LED light strip is integrated into the base along with the diffuser panel, creating a unified illumination assembly that simplifies the overall structure while achieving even light distribution and source concealment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design enhances manufacturability, simplifies access to the display chamber, and provides uniform and aesthetically pleasing illumination, improving the overall display experience while maintaining protection and visibility of the item.
Implementation Method 1
the head of the fastener opposite from the rear panel removably engages a magnet connected to the removable front panel. Accordingly, the magnets engage the ferrous head of the post and hold the front face onto the display.
Implementation Method 2
integrated LED light strip within the base of the modular case... provides uniform and aesthetically pleasing illumination

AI summary
A modular display case having a chamber for holding an item to be displayed, such as a folded flag, as well as a chamber for housing an illuminating LED strip within the base of the case. The case is made from multiple layers of material spaced apart with ring spacers between the front panel and back panel which are connected with fasteners. The front panel of the case is removably attached to the body of the case and is seated within a tray in the integrated base. The item held in the display chamber is visible through slats between the layers as well as through the viewing windows on the front and rear panels of the case. The rear panel of the case is generally solid whereas the front panel is removably attached to the body of the case and thereby permits access to the display chamber.
