Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses have limitations in door rotation, as the door can only open and close in one direction, restricting user flexibility and potentially causing issues when switching between rotational axes.
Innovation Solution
The apparatus features a door that can rotate about two different axes, with a manipulation unit and locking mechanisms allowing users to switch between these axes, ensuring the door opens the introduction port effectively while preventing unintended axis switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door is configured to rotate about only one vertical axis, then the structure is simple and stable, but the user flexibility and adaptability are limited
Solution Approach 1:
The door system transitions from a static single-axis configuration to a dynamic multi-axis configuration. The door can switch between rotating about the first vertical axis (when closed) and the second axis extending from the front surface (when opening), allowing adaptive movement patterns based on operational state. This dynamic reconfiguration enables the door to accommodate different opening directions and user needs while maintaining structural simplicity through state-dependent behavior.
Solution Approach 2:
The door assembly is designed to perform multiple functions through a unified structure. The same door body serves both as a closed barrier rotating about the first vertical axis and as an opening element that can pivot about the second axis. The manipulation unit and locking mechanisms enable the door to universally handle different opening scenarios (inward, outward, sideways) without requiring separate mechanisms for each function, thereby improving adaptability while controlling complexity.
2Adaptability or versatility
If the door can switch between rotational axes, then user flexibility is improved, but unintended axis switching may occur reducing reliability
Solution Approach 1:
The locking mechanism is designed to preemptively secure the door to the appropriate rotational axis before opening operations begin. When the door is closed, the locking mechanism预先 engages to fix the door to the first vertical axis, preventing any unintended switching during normal operation. This preliminary action ensures that axis switching only occurs when deliberately initiated by the manipulation unit, thereby maintaining reliability while allowing flexibility.
Solution Approach 2:
The system incorporates feedback through the locking mechanism that detects and responds to the door's operational state. The locking mechanism monitors whether the door is in a closed position (engaging the first vertical axis lock) or in an opening position (allowing switching to the second axis). This feedback loop ensures that axis switching occurs only under appropriate conditions, preventing unintended switching and maintaining system reliability while preserving user flexibility.
3Reliability
If locking mechanisms are added to prevent unintended switching, then reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing door structure and manipulation unit rather than being added as a separate complex subsystem. The locking components are integrated into the door assembly, utilizing the same spatial envelope and structural elements already present. This merging approach enables reliable axis switching control while minimizing the increase in overall device complexity, as the locking function is achieved through clever integration rather than additional independent mechanisms.

AI summary
A laundry treating apparatus includes a door, where a first rotational axis forms a rotation center of the door, and a second rotational axis forms another rotation center of the door. The second rotational axis is provided to rotate the door in a direction different from a direction in which the door is rotated about the first rotational axis. A first switching unit is configured to connect the door to the first rotational axis, and a second switching unit is configured to connect the door to the second rotational axis when the first switching unit is moved in a direction in which the door is separated from the first rotational axis.
