Door for mounting a removable electronic display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerated display case doors with embedded displays are costly and difficult to maintain, and existing solutions do not provide efficient methods for displaying content without altering the door's profile or interfering with adjacent doors in a lineup.
Innovation Solution
A display case door design featuring an insulated panel assembly with an electronic display overlay, a mounting bezel, and a circuitry module, where the electronic display is securely attached to the door frame using display retainers and covers, allowing for easy replacement and maintenance without altering the door's thickness or spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic displays are embedded into refrigerated display case doors, then content display capability is improved, but manufacturing cost and maintenance difficulty increase
Solution Approach 1:
The display system is segmented into separate components: the insulated door panel assembly and the electronic display overlay. The display is mounted on the exterior surface of the door rather than being embedded within the insulation, allowing the door itself to remain a simple, cost-effective insulated panel while the display functionality is added as a separate, replaceable component.
Solution Approach 2:
The electronic display is extracted from the door structure and mounted as an external overlay component. This extraction allows the display to be independently replaced, maintained, or upgraded without affecting the door's insulation integrity or requiring complex embedding modifications to the door assembly.
2Adaptability or versatility
If electronic displays are embedded into refrigerated display case doors, then content display capability is improved, but maintenance difficulty increases
Solution Approach 1:
The display system is divided into separable components with the display mounted as an external overlay that can be independently removed and replaced without disassembling the door or affecting other components, enabling straightforward maintenance and replacement operations.
3Adaptability or versatility
If display components are added to the door, then content display capability is improved, but device complexity increases
Solution Approach 1:
The door assembly is segmented into distinct functional components: the insulated panel, the mounting bezel structure, the electronic display, and protective covers. This segmentation allows each component to be independently manufactured, installed, and maintained, reducing overall system complexity despite adding display functionality.
Solution Approach 2:
The mounting bezel and cover structures serve multiple functions: they provide mechanical support for the display, seal the display assembly, protect internal components, and maintain the door's aesthetic appearance. This multi-functionality reduces the need for additional separate components, thereby managing complexity.
4Reliability
If mounting structures are added to secure the display, then display stability is improved, but interference with adjacent doors in lineup increases
Solution Approach 1:
The mounting bezel and protective covers are designed to nest within the existing door frame structure and overlap with adjacent doors' coverage areas. The bezel is secured to the door frame and extends outward to hold the display, while the covers wrap around the bezel and display edges, creating a compact integrated assembly that does not protrude beyond the door's external envelope.

AI summary
In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes an insulated panel assembly that is transparent to visible light. The door further includes a door frame extending about and secured to a peripheral edge of the insulated panel assembly, an electronic display overlaying the insulated panel assembly, and at least one display retainer secured to the door frame and having a coupling end that mates with the electronic display to releasably secure the display to the door frame.
