Dual-Axis Laundry Door Hinge for Alignment and Safe Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laundry treating apparatuses face issues with the door's rotational axis switching mechanism, where the user experiences inconvenience due to restricted finger motion and potential misalignment of the door's rotational axes, leading to incomplete closure of the introduction port and risk of mechanical damage from excessive rotational speed.
Innovation Solution
The apparatus incorporates a dual rotational axis system with a handle mechanism that allows switching between rotational axes X and Y, and a lock mechanism to secure the switching units when the door opens, ensuring proper alignment and preventing mechanical damage through a damper system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door is equipped with a rotational axis switching mechanism, then the door can rotate in multiple directions, but the user experiences restricted finger motion and operational inconvenience
Solution Approach 1:
The door hinge system dynamically switches between two rotational axes (X-axis and Y-axis) based on operational needs. The switching mechanism allows the door to adapt its rotation direction, providing versatility while maintaining ease of operation through intuitive handle-based control.
Solution Approach 2:
A switching unit acts as an intermediary between the user's handle operation and the door's rotational axis selection. This mediator translates simple user input into complex mechanical responses, resolving the contradiction between versatile rotation and ease of operation.
2Adaptability or versatility
If the door rotates about multiple rotational axes, then operational flexibility is improved, but misalignment of rotational axes occurs leading to incomplete closure of the introduction port
Solution Approach 1:
The system incorporates feedback mechanisms through the switching units that detect and correct rotational axis misalignment. When the door rotates about either the X-axis or Y-axis, the switching unit ensures proper alignment before engagement, preventing incomplete closure of the introduction port.
Solution Approach 2:
The switching unit performs preliminary alignment actions before the door completes its rotation. By pre-positioning the rotational axes correctly and ensuring proper engagement sequence, the system prevents misalignment issues that would lead to incomplete port closure.
3Speed
If the door rotates rapidly, then opening speed is improved, but mechanical damage occurs due to excessive rotational speed
Solution Approach 1:
The damper system provides beforehand cushioning by opposing the door's rotational motion during opening. This controlled resistance prevents excessive rotational speed and potential mechanical damage while still allowing rapid door opening through regulated energy dissipation.
Solution Approach 2:
The damper converts the potentially harmful kinetic energy from rapid door rotation into beneficial controlled motion. By transforming the harmful effect of excessive speed into a controlled damping force, the system protects mechanical components while maintaining fast opening performance.

AI summary
The laundry treating apparatus includes a door to open and close the introduction port about a first rotational or a second rotational axis which is different from first rotational axis. A first switching unit is provided in the door to allow rotation of door about the first rotational axis, and a second switching unit is provided in the door to allow rotation of the door about the second rotational axis. A lock fixes a position of at least one of the first switching unit or second switching unit when the door opens the introduction port. As can be appreciated, the mechanism used for the laundry apparatus may be applicable to other home appliances or non-home appliances where two different rotational axes may be needed to open and close a door.
