Laundry treating apparatus with door and method for fabricating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses have a separate configuration of doors and control units, which complicates their appearance and lacks a seamless integration of touch screens, particularly due to misalignment issues between door covers, touch sensors, and display modules.
Innovation Solution
A structured alignment between the door cover and touch sensor, and between the touch sensor and display module, is implemented to create a seamless touch screen interface on the door, ensuring accurate positioning and reliability, with the touch sensor being attached to the rear surface of the door cover and aligned using guide marks for precise assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch sensor and display module are separately fabricated and attached to the door cover, then the touch screen can be implemented on the door, but misalignment occurs between the door cover, touch sensor, and display module
Solution Approach 1:
Guide marks are formed on the door cover before attaching the touch sensor and display module. These pre-formed guide marks establish reference positions that ensure accurate alignment during the assembly process, preventing misalignment between components.
Solution Approach 2:
The guide marks act as an intermediary element between the door cover, touch sensor, and display module. By providing a common reference system, the guide marks mediate the alignment relationship between these three components, ensuring they are precisely positioned relative to each other.
2Device complexity
If the control unit is integrated into the door with a touch screen, then the appearance is simplified and user interaction is enhanced, but the alignment between components becomes more complex
Solution Approach 1:
Guide marks are formed on the door cover in advance before assembly. This preliminary action provides clear alignment references that simplify the assembly process, allowing workers to quickly and accurately position the touch sensor and display module without complex alignment procedures.
3Manufacturing precision
If guide marks are formed on the door cover for alignment, then accurate positioning is achieved, but the door cover requires additional processing steps
Solution Approach 1:
The guide marks replace complex mechanical alignment systems. Instead of using elaborate mechanical fixtures or complex positioning mechanisms, simple visual guide marks are formed on the door cover, which can be created through straightforward marking or printing processes.
