Washer Door Touchscreen Assembly With Moisture-Sealed Circular Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry treating apparatuses face challenges in integrating a touch screen on the door, including difficulties in sealing electronic elements, maintaining a high-quality aesthetic, and ensuring reliable operation due to moisture issues and complex assembly processes, especially when using circular shapes.
Innovation Solution
The design incorporates a door cover with a non-light-transmitting region and light-transmitting regions, a touch sensor integrated with the door cover, and a sealant filling groove to prevent moisture ingress and enhance assembly accuracy, allowing for a circular display appearance while using a rectangular display module for cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a glass door cover is used to give a high-quality feeling, then aesthetic appearance is improved, but mechanical fastening becomes difficult and sealing reliability deteriorates
Solution Approach 1:
The patent combines mechanical fastening (bracket with positioning protrusions) and chemical bonding (adhesive) to secure the glass door cover. The bracket provides structural support and positioning, while the adhesive ensures sealing and prevents moisture ingress, thus maintaining both aesthetic appearance and sealing reliability
Solution Approach 2:
The patent introduces a bracket as an intermediary component between the door frame and the glass door cover. The bracket serves as a mediator that facilitates the connection of glass material to the door frame through positioning protrusions and grooves, enabling both mechanical fastening and aesthetic presentation
2Shape
If adhesive is coated at an inner side of the door frame far from the edge to prevent leakage, then appearance quality is improved, but joint strength deteriorates and foreign substance infiltration increases
Solution Approach 1:
The patent combines mechanical fastening through the bracket and chemical bonding through adhesive positioned away from edges. The bracket provides the primary joint strength through positioning protrusions, while the adhesive positioned inward prevents leakage and maintains appearance quality without compromising overall joint strength
3Shape
If a circular door cover is used for aesthetic design, then appearance quality is improved, but alignment precision during assembly deteriorates
Solution Approach 1:
The patent introduces asymmetric positioning protrusions and corresponding positioning grooves on the circular door cover and bracket. This asymmetric feature breaks the rotational symmetry of the circular shape, providing a unique correct installation position and ensuring precise alignment during assembly while maintaining the aesthetic circular appearance
4Ease of operation
If a touch screen is provided on the door for advanced interface, then ease of operation is improved, but moisture sealing becomes more critical and device complexity increases
Solution Approach 1:
The patent combines the touch screen with the door cover structure, integrating the electronic interface into the existing door assembly. The door cover serves as both the aesthetic exterior and the mounting substrate for the touch screen, reducing overall device complexity while maintaining ease of operation
Solution Approach 2:
The patent introduces a bracket as an intermediary structure that mounts the door cover (with integrated touch screen) to the door frame. This bracket with positioning protrusions and grooves simplifies the assembly process and ensures proper alignment, reducing device complexity while enabling the advanced touch screen interface
