A door for washing and/or drying machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing and drying device doors are inconvenient to reorient due to the need to separate components, which can damage delicate parts like hinges and gaskets during the process.
Innovation Solution
A door design that allows changing the opening/closing direction by rotating the main body and associated components without separating the first and second covers, minimizing damage to delicate components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door components are separated to change the opening direction, then the opening direction can be changed, but the delicate components (hinge, door lock, gasket) may get damaged
Solution Approach 1:
The door is divided into two annular covers (first and second) that can be independently positioned, with the main body rotatable within the movement space between them. This segmentation allows the main body to be rotated 180 degrees to change opening direction while keeping the covers assembled, preventing damage to delicate components.
Solution Approach 2:
The main body is designed to be rotatable within the movement space formed between the first and second covers, enabling dynamic reconfiguration of the door's opening direction. The fixing members allow the main body to be securely fixed in different rotational positions, providing both mobility for reorientation and stability for secure mounting.
2Adaptability or versatility
If the front door ring and rear door ring are separated and rotated 180 degrees to change opening direction, then the opening direction changes, but the process is inconvenient and time-consuming
Solution Approach 1:
The door structure is segmented into first and second covers with a rotatable main body between them, allowing the opening direction to be changed by rotating only the main body rather than separating and reassembling entire door rings. This reduces reconfiguration time and complexity.
Solution Approach 2:
The main body is designed for easy rotation within the movement space, with fixing members that can be quickly engaged or disengaged to change the opening direction. This dynamic design enables rapid reconfiguration without time-consuming disassembly and reassembly operations.
3Adaptability or versatility
If the door components are separated for reconfiguration, then the opening direction can be changed, but the delicate components may not perform their functions effectively
Solution Approach 1:
The door is segmented into first and second covers with the main body rotatable between them, allowing opening direction changes without separating components that house delicate elements. This ensures hinges, locks, and gaskets remain properly positioned and functional.
Solution Approach 2:
The main body can be dynamically rotated to different positions while the fixing members ensure secure attachment in each position. This maintains proper alignment and functionality of all door components regardless of the opening direction, ensuring ease of operation.
