Display Case Door Frame Electrical Connection for Embedded Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerated display case doors with embedded display panels are costly and difficult to maintain, and existing methods for displaying content are not efficient.
Innovation Solution
A display case door design that integrates external power and data connections within the door frame, using a female electrical connector mounted inside the frame with corresponding openings and a male connector for secure and robust electrical connections, allowing for the mounting of video displays and insulated panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical connections are integrated into the door structure, then content display capability is improved, but maintenance difficulty and cost increase
Solution Approach 1:
The electrical connection system is segmented into separate male and female connectors. The female connector is integrated into the door frame, while the male connector remains accessible outside the door. This segmentation allows the door to display content when closed (improving adaptability) while keeping the male connector accessible for maintenance without disassembling the door structure (improving ease of repair).
Solution Approach 2:
The door frame serves as an intermediary structure that houses the female electrical connector. This intermediary placement allows electrical connections to be made through the door frame's opening, enabling content display integration while maintaining accessibility for plugging and unplugging connectors during maintenance operations.
2Use of energy by moving object
If electrical connections are made through the door structure, then power supply for displays is enabled, but risk of electrical arcing increases
Solution Approach 1:
The electrical connection function is extracted from the door's structural components (hinges, handles). Instead of routing electricity through load-bearing structural elements, the patent creates dedicated electrical pathways through the door frame with separate connectors. This separation reduces the risk of electrical arcing affecting structural integrity and makes the electrical system safer and more maintainable.
Solution Approach 2:
The door frame acts as an intermediary that provides a safe, dedicated pathway for electrical connections. By routing power and data cables through the door frame's opening and using separate male/female connectors positioned at the opening, the system enables power supply for displays while minimizing electrical arcing risks through proper isolation from structural components.
3Adaptability or versatility
If embedded display panels are installed in doors, then advertising effectiveness is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The display system is segmented into three separate components: the door structure itself, the video display unit, and the electrical connection system. This allows each component to be manufactured independently using standard processes, then assembled together. The door frame includes a pre-designed opening for the electrical connector, simplifying the manufacturing integration while enabling effective content display for advertising purposes.

AI summary
A display case door that includes a frame around at least a portion of the display case door with an electrical connection installed within the frame. The electrical connector includes at least one opening defined within a surface of the electrical connector corresponding with at least one female electrical terminal. The electrical connector is mounted inside the door frame and the surface of the electrical connector is aligned with an opening in a sidewall of the door frame.
