Door-Integrated Control Panel for Simplified Laundry Appliance Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses face complexity in fabrication and user manipulation due to the placement of the control panel on the top or front cover, requiring inconvenient dismantling for repairs when faults occur.
Innovation Solution
The control panel is integrated onto the door assembly, allowing for simplified manufacturing and user interaction, with a separable control panel cover that enables easy replacement or repair without disassembling the cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the control panel is provided on the top surface or front cover, then the fabrication process becomes complicated and repair requires dismantling, but the control panel is protected from direct user access
Solution Approach 1:
The control panel is merged with the door assembly, integrating it into the existing door structure rather than placing it separately on the top surface or front cover. This reduces the number of separate components and simplifies the overall fabrication process while maintaining protection through the door's structural design
2Device complexity
If the control panel is provided on the top surface or front cover, then the structure is separated, but repair requires inconvenient dismantling of the cabinet
Solution Approach 1:
The control panel is segmented as a separate, detachable component integrated into the door assembly. This allows the control panel to be independently removed for repair by simply detaching it from the door, without requiring dismantling of the entire cabinet or front cover structure
3Ease of manufacture
If the control panel is integrated onto the door assembly, then manufacturing is simplified and repair is facilitated, but the control panel requires direct placement on the door structure
Solution Approach 1:
The control panel is merged with the door assembly, integrating it into the existing door structure rather than placing it separately on the top surface or front cover. This reduces the number of separate components and simplifies the overall fabrication process while maintaining protection through the door's structural design

AI summary
A laundry treatment apparatus including a cabinet defining an external appearance, a drum rotatably provided inside the cabinet to accommodate laundry, and a door assembly pivotably provided at the cabinet to open or close an opening in the drum. The door assembly includes a door body configured to open or close the cabinet, a control panel provided on an inner surface of the door body to receive an input related to operation from a user and to display operation of the laundry treatment apparatus, and a control panel cover separably provided on a rear surface of the control panel to define a rear surface of the door assembly. The control panel includes an input unit configured to receive the input related to operation from the user, a display unit configured to display the input received from the input unit, and a PCB configured to control the control panel.
