Solution Overview

Problem

Traditional hinge technology in embedded home appliances causes interference between the door panel and the cabinet side wall during opening and closing, preventing normal operation of the door body assembly.

Innovation Solution

A door body assembly with an active slide door mechanism and a traction mechanism that allows the door panel to slide relative to the box door, avoiding obstacles during rotation, and a driven slide door mechanism for additional support and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a door panel is fixed at the surface of the box door to improve home furnishing integration, then the aesthetic integration effect is improved, but the door panel interferes with the cabinet side wall during opening and closing

Engineering Contradiction:
Improvehome furnishing integration effectVSAvoiddoor opening and closing operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The door panel is transformed from a static fixed structure to a dynamic sliding structure. The active slide door mechanism enables the door panel to automatically adjust its position during opening and closing operations, sliding along guide rails to avoid interference with the cabinet side wall while maintaining the embedded aesthetic appearance when closed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The active slide door mechanism acts as an intermediary between the door panel and the box door. This mechanism includes a first slider connected to the box door, a second slider connected to the door panel, and a connector linking them, enabling controlled relative movement while maintaining connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If traditional hinge technology is used, then the structure is simple, but the door body assembly fails to open or close normally due to interference with the side wall

Engineering Contradiction:
Improvehinge structure simplicityVSAvoiddoor opening and closing functionality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The door body assembly is segmented into multiple functional components: the box door, the door panel, and the active slide door mechanism with separate sliders and guide rails. This segmentation allows each component to perform its specific function independently, with the first slider handling box door movement and the second slider handling door panel positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces dynamic movement capabilities through the active slide door mechanism, transforming the traditionally static hinge connection into a dynamic system that can adapt its configuration during operation to avoid side wall interference.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the door panel is made to slide during opening and closing, then interference with obstacles is avoided, but the mechanism complexity increases

Engineering Contradiction:
Improvedoor operation smoothnessVSAvoidslide door mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The door panel is transformed from a static fixed structure to a dynamic sliding structure. The active slide door mechanism enables the door panel to automatically adjust its position during opening and closing operations, sliding along guide rails to avoid interference with the cabinet side wall while maintaining the embedded aesthetic appearance when closed.

Inventive Principle:

AI summary

The present application relates to the technical field of home appliances and provides a door body assembly and a refrigeration device. The door body assembly comprises: an enclosure door, which is rotatably connected to an enclosure body and is adapted for opening or closing a storage space of the enclosure body; a door panel, which is slidably arranged at an outer side of the enclosure door; and a driving sliding door mechanism, which is arranged on the enclosure door and is configured to drive the door panel to move in the width direction of the enclosure door during opening or closing of the enclosure door. In the door body assembly of an embodiment of the present application, the driving sliding door mechanism is arranged on the enclosure door, and the driving sliding door mechanism is respectively connected to the enclosure door and the door panel, so as to drive the door panel to slide in the width direction of the enclosure door during when rotating relative to the enclosure body to open or close the enclosure door, allowing the door panel to be able to avoid an obstruction such as a wall or an object at one side during opening or closing of the enclosure door. Interference between the door panel and the obstacle that affects the rotation of the enclosure door is prevented, and use requirements of a user in different scenarios can be satisfied.
