Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of home appliances into cupboards often results in door body assemblies interfering with sidewalls during opening and closing, leading to improper operation.
Innovation Solution
A door body assembly with a slide mechanism and traction mechanism that allows the door panel to move relative to the box door, ensuring a maximum door opening angle of 90° to 135° and a minimum movement distance of 14.15 mm to 109.108 mm, preventing interference and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional hinge technology is used to connect the door panel to the box door, then the structure is simple and easy to manufacture, but the door panel interferes with the sidewall of the mounting space during opening and closing processes
Solution Approach 1:
The patent applies the dynamics principle by transforming the static door panel into a dynamic structure that can change its position relative to the box door. The slide mechanism allows the door panel to move along the width direction of the box door, changing from a fixed position to a movable position that avoids interference with the sidewall during opening and closing operations.
Solution Approach 2:
The patent introduces a slide mechanism as an intermediary component between the door panel and the box door. This intermediary mechanism enables the door panel to move relative to the box door, solving the interference problem without requiring a complete redesign of the hinge system.
2Stability of the object's composition
If the door panel is fixedly connected to the box door, then the structure is stable and simple, but the door body assembly cannot be properly opened or closed when embedded in a cupboard
Solution Approach 1:
The patent transforms the fixed connection into a dynamic connection using the slide mechanism. The door panel can move along the width direction of the box door by a movement distance d, allowing the door body assembly to be properly opened and closed when embedded in a cupboard while maintaining stability through the guide rail and slider structure.
3Ease of operation
If the door panel is allowed to move relative to the box door to avoid sidewall interference, then the ease of operation is improved, but the device complexity increases due to the slide mechanism and traction mechanism
Solution Approach 1:
The patent introduces dynamic elements (slide mechanism and traction mechanism) to enable the door panel to move relative to the box door, improving ease of operation by avoiding sidewall interference during opening and closing.
Solution Approach 2:
The traction mechanism is designed to automatically drive the slide mechanism during the opening and closing process of the box door. The system uses the door's own movement to power the panel adjustment, reducing the need for external control systems and minimizing added complexity.
4Shape
If a larger movement distance d is provided for the door panel, then the maximum door opening angle increases (90° to 135°), but the slide mechanism becomes more complex and requires larger mounting space
Solution Approach 1:
The patent achieves different maximum door opening angles (90° to 135°) by adjusting the movement distance d of the door panel, which is controlled by the slide mechanism. The minimum value of the movement distance d is between 14.15 mm and 109.108 mm, allowing flexibility in achieving the desired opening angle while managing complexity.

AI summary
The present application relates to the technical field of household appliances and provides a door body assembly for a built-in refrigeration device and a refrigeration device. The door body assembly comprises: an enclosure door, which is rotatably connected to a refrigeration enclosure body, the refrigeration enclosure body being built into an accommodating space formed by an installation body, the distance between the center of a hinge axis of the enclosure door and an opening of the accommodating space being t, and the distance between the center of the hinge axis and an end face of the hinge side of the enclosure door being l3; a sliding mechanism; a door panel, which is movably mounted on the enclosure door by means of the sliding mechanism, the door panel being able to move in the width direction of the enclosure door, and the movement distance being d; and a traction mechanism, the traction mechanism being connected to the sliding mechanism, and during opening or closing of the enclosure door, the traction mechanism driving the sliding mechanism to move, so as to drive the door panel to move relative to the enclosure door; the maximum door angle that the door body assembly opens is 90°-135°, the minimum value of the movement distance d of the door panel is 14.15-109.108 mm, and the maximum angle that the door opens has a positive correlation with the minimum value of the movement distance d.
