Solution Overview

Problem

Existing display case doors with electronic displays face challenges in maintainability, structural integrity, and versatility, as they often require complex mounting processes that compromise the structural strength and manufacturability, and do not allow for easy replacement or maintenance without compromising the structural integrity.

Innovation Solution

The implementation of a display case door design that includes an insulated panel assembly, a door frame with mounting blocks and side rails, and an electronic display assembly with brackets and hangers, allowing for secure and adjustable mounting of electronic displays without cutting or notching the side rails, enabling easy maintenance and compatibility with various door and display sizes using common tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronic displays are mounted directly to the door frame using complex mounting processes, then the electronic display can be securely attached, but the structural strength of the door frame is compromised and manufacturing becomes more difficult

Engineering Contradiction:

Improvesecure attachment of electronic displayVSAvoidstructural strength of door frame

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The mounting system is divided into separate components: mounting blocks attached to the door frame, and brackets attached to the electronic display. This segmentation allows the door frame to maintain its structural integrity while still providing secure attachment points for the display through the distributed mounting blocks and brackets.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Mounting blocks serve as intermediary elements between the door frame and the electronic display brackets. These blocks are attached to the door frame and provide attachment points for the brackets, thereby mediating the connection and preventing direct attachment that would compromise the door frame's structural strength.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the door frame is cut or notched to accommodate electronic displays, then the display can be integrated into the door, but the structural integrity and manufacturability of the door frame are compromised

Engineering Contradiction:

Improveintegration of electronic display into doorVSAvoidmanufacturability of door frame

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Mounting blocks are pre-attached to the door frame before the electronic display is installed. This preliminary action allows the door frame to be manufactured in its complete, strong form without requiring later cutting or notching operations, thereby maintaining both structural integrity and ease of manufacture.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of modifying the door frame to accommodate the display (cutting/notching), the approach is inverted: mounting blocks are added to the door frame, and then the display is attached to these blocks. This reversal eliminates the need for invasive modifications to the door frame.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If complex mounting processes are used to attach electronic displays, then secure attachment is achieved, but maintenance and replacement become difficult

Engineering Contradiction:

Improvesecure attachment of electronic displayVSAvoidmaintainability of electronic display

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The mounting system is segmented into detachable components (mounting blocks and brackets) that can be independently removed. This segmentation allows the electronic display to be easily detached from the door frame by removing the brackets from the mounting blocks, facilitating simple maintenance and replacement while maintaining secure attachment during normal use.

Inventive Principle:

Principle #1Segmentation

4Manufacturing precision

If custom mounting solutions are designed for specific door and display sizes, then precise fit is achieved, but versatility across different sizes is reduced

Engineering Contradiction:

Improveprecise fit of mounting componentsVSAvoidcompatibility with various door and display sizes

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The mounting blocks and brackets are designed as universal components that can accommodate various door and display sizes. The mounting blocks can be positioned at different locations on the door frame, and the brackets can be configured to fit different display dimensions, allowing the same basic mounting system to serve multiple size configurations without requiring custom-designed components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display case door includes an insulated panel assembly, a door frame, and one or more mounting blocks. The insulated panel assembly is transparent to visible light. The door frame extends about and is coupled to the insulated panel assembly. The one or more mounting blocks are coupled to and extend inwardly from the door frame. The electronic display assembly includes an electronic display, and one or more side brackets coupled to the electronic display. At least one of the side brackets of the electronic display assembly is coupled to at least one of the one or more mounting blocks. The electronic display is at least partially supported on at least one of the one or more mounting blocks.
