Detergent Drawer Handle Structure for Curved Door Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating devices with a front load type face issues with the joining force between the handle panel and the detergent box being weakened due to a curved handle panel design, leading to potential separation and breakage when external forces are applied.
Innovation Solution
The design includes a preventing part with a fastening portion on the coupling panel and a fixing portion on the handle panel, featuring projection hooks, support ribs, and perforated holes to securely join the handle panel to the detergent box, enhancing the joining force and preventing separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the handle panel is designed with a curved shape to match the door's outer circumference, then the aesthetic appearance and unity of the laundry treating device is improved, but the joining force between the handle panel and detergent box is weakened
Solution Approach 1:
The handle panel is divided into multiple sections: a curved outer circumferential portion for aesthetic appearance and a separate substantially rectangular inner portion for strong joining. This segmentation allows each part to fulfill its specific function - the curved outer portion provides aesthetic unity with the door, while the rectangular inner portion maintains strong joining force with the detergent box through multiple joining portions at its corners.
2Shape
If the handle panel is made curved to avoid the door, then the aesthetic unity is improved, but the handle panel may be spaced apart from the detergent box when external force is applied
Solution Approach 1:
The handle panel merges two functional regions: a curved outer circumferential portion that provides aesthetic appearance and avoids the door, and a substantially rectangular inner portion that ensures reliable connection to the detergent box. The rectangular inner portion incorporates multiple joining portions that collectively prevent the handle panel from spacing apart from the detergent box even when external forces are applied during handle operation.
3Shape
If the handle panel is designed as curved, then the aesthetic impression is improved, but the curved portion may be broken when the user draws the handle
Solution Approach 1:
The handle panel is segmented into a curved outer circumferential portion for aesthetics and a substantially rectangular inner portion for structural strength. The rectangular inner portion contains multiple joining portions positioned at its corners that provide robust mechanical connection points. This segmentation ensures that the curved portion, which is more susceptible to breakage, does not bear the full mechanical stress of handle operation, while the rectangular portion with multiple joining points distributes and withstands the forces applied during handle drawing.
4Ease of operation
If the door diameter is made large to facilitate user access to input and display units, then the ease of operation is improved, but the door center becomes higher and the top part of the door is nearer to the front top part of the cabinet
Solution Approach 1:
The handle panel employs a curved outer circumferential shape that complements and harmonizes with the large-diameter door's circular form. This curvature design allows the handle panel to aesthetically integrate with the door's prominent circular feature, creating visual unity between the door and handle assembly despite the door's elevated position and large size.

AI summary
A cabinet includes a front panel having an opening at a front side, a door seated on the front panel, the door having a diameter greater than that of the opening to open/close the opening, a control panel located at a top part of the front panel, the control panel defining a seating recess configured to seat a top part of the door and a draw hole at a lateral side of the seating recess, a detergent box drawably located in the draw hole and configured to receive detergent, a handle panel coupled to a front side of the detergent box, the handle panel including one side configured as an avoidant surface corresponding to a shape of an outer circumference of the seating recess, and a preventing part configured to prevent the avoidant surface from being spaced apart from the front side of the detergent box.
