Laundry Door Touchscreen Assembly With Alignment Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses have a separate configuration of doors and control units, which interferes with the appearance and creates inconvenient input and output interfaces, and existing solutions for integrating touch screens on doors lack alignment between the door cover, touch sensor, and display module, affecting reliability and assembly.
Innovation Solution
The integration of a touch sensor and display module on a door cover with a transparent region, where the touch sensor is attached to the rear surface of the door cover, aligned with the display module, and the touch sensor covers the transparent region to detect touch inputs, providing a unified interface for user input and output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control unit is installed at the main body with separate buttons or knobs, then the input and output interfaces are simple, but the appearance is interfered with and user interaction is inconvenient
Solution Approach 1:
The control unit is moved from the main body to the door, merging the control functions with the door structure. This integration allows the door to serve dual purposes: physical access control and user interface for operation control, thereby improving ease of operation while maintaining configuration simplicity through functional consolidation
2Ease of operation
If a touch screen is integrated on the door, then user interaction is enhanced, but alignment between door cover, touch sensor, and display module becomes difficult
Solution Approach 1:
Alignment marks are pre-formed on both the door cover and the touch sensor before assembly. These marks serve as guides during the assembly process, ensuring that the touch sensor, display module, and door cover are precisely aligned without requiring complex alignment procedures or specialized equipment
Solution Approach 2:
Alignment marks act as intermediary elements between the door cover and touch sensor assembly. These visual markers provide a reference system that mediates the alignment process, making it easier to achieve precise positioning of the touch sensor relative to the door cover and display module
3Ease of manufacture
If the touch sensor is separately fabricated and attached to the door cover, then manufacturing flexibility is improved, but attachment position accuracy deteriorates
Solution Approach 1:
Alignment marks are pre-formed on both the door cover and touch sensor during their respective manufacturing processes. This preliminary preparation allows each component to be manufactured separately with manufacturing flexibility, while the pre-positioned alignment marks ensure that when they are assembled, the attachment position accuracy is maintained

AI summary
A laundry treating apparatus includes a main body having a laundry introduction opening, and a door capable of opening and closing the laundry introduction opening, wherein the door includes a door cover defining an appearance of the door, and provided with a transparent region and an opaque region surrounding the transparent region, a display module disposed on a rear surface of the door cover and capable of outputting visual information through the transparent region, and a touch sensor attached to a rear surface of the door cover to cover the transparent region and capable of sensing a touch input applied to the transparent region, wherein the touch sensor is provided with an align mark to allow the touch sensor to be attached to a correct position with respect to the transparent region.
