Solution Overview
Problem
Drum-type washing machines experience vibration and noise transmission from the tub to the cabinet due to rotational forces, and there is a risk of foreign objects entering the gap between the cabinet and tub doors during laundry operations.
Innovation Solution
A washing machine design featuring a gap-shielding device that selectively closes the gap between the cabinet and tub doors in response to opening and closing, using a movable body and actuator to shield the gap and prevent foreign object entry, while also reducing vibration and noise transmission through improved structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap is defined between the front cabinet and the tub door for movement of the tub, then the tub can move freely during operation, but foreign objects such as coins or buttons may be introduced into the cabinet through the gap
Solution Approach 1:
A gap-shielding device is introduced as an intermediary component between the front cabinet and the tub door. This device includes a shielding plate that can move between a retracted position (allowing tub movement) and a shielding position (blocking foreign object entry). The shielding plate is positioned to block the gap when the tub door is in the closed position, preventing foreign objects from entering while allowing the tub to move freely during operation.
2Object-affected harmful factors
If the gap-shielding device is positioned to block foreign objects, then foreign object entry is prevented, but the tub movement space is reduced
Solution Approach 1:
The gap-shielding device is designed with dynamic positioning capability. The shielding plate can be retracted to allow maximum tub movement space when not needed, and extended to block the gap when the tub door is closed. The device includes a driving mechanism that adjusts the shielding plate position based on the tub door state, ensuring that the shielding function is activated only when necessary, thus maintaining maximum tub movement space during operation.
3Object-affected harmful factors
If the gap-shielding device is always in the shielding position, then foreign objects are prevented from entering, but the device complexity increases
Solution Approach 1:
The gap-shielding device is designed to operate automatically based on the tub door state. The driving mechanism detects whether the tub door is open or closed and autonomously adjusts the shielding plate position accordingly. When the tub door is closed, the shielding plate automatically moves to the shielding position; when the tub door is open, the shielding plate automatically retracts. This self-service operation eliminates the need for complex manual control systems while maintaining effective foreign object prevention.
