Front-Load Washer Door Angles for Guided Loading and Shelf Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front loading laundry treatment apparatuses face difficulties in adjusting the rotating angle of the door and opening degree, requiring users to bend when loading or unloading laundry, and often have limited flexibility in door configuration.
Innovation Solution
The apparatus features a door with adjustable rotating angles, allowing it to function as a guide for loading and a shelf for unloading, and can include multiple doors with different rotating directions and maximum angles, utilizing hinges and support mechanisms to maintain desired positions and facilitate easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is fixed in a standard position for front loading apparatus, then the cabinet structure is simple, but the user must bend at the waist when loading laundry
Solution Approach 1:
The door is designed with adjustable positioning capabilities, allowing it to be dynamically repositioned between multiple fixed angles. The door position adjustment mechanism enables the door to transition between a first position (optimized for loading) and a second position (optimized for unloading), transforming a static structure into a dynamic one that adapts to different operational requirements.
Solution Approach 2:
The door's rotational angle parameter is made variable through the adjustment mechanism. By changing the door's angular parameter between specific ranges, the system optimizes accessibility for different tasks - reducing the bending angle required for loading operations while maintaining structural feasibility.
2Adaptability or versatility
If the door rotating angle is fixed, then the mechanism is simple, but the opening degree cannot be adjusted for different loading needs
Solution Approach 1:
The door mechanism transitions from a fixed angular configuration to a dynamic system with multiple adjustable positions. The rotating angle adjustment mechanism allows the door to be positioned at different angles within a permissible range, enabling adaptation to various loading scenarios while maintaining mechanical simplicity through predefined position stops.
3Adaptability or versatility
If a single door configuration is used, then the device structure is simple, but it cannot serve both as a loading guide and an unloading shelf
Solution Approach 1:
The door is designed to perform multiple functions by being positionable in different configurations. In the first position, it serves as a loading guide; in the second position, it functions as an unloading shelf. This multi-functionality is achieved through the position adjustment mechanism that allows the same door structure to fulfill different operational roles without requiring separate components.
Solution Approach 2:
The door's functional characteristics are made dynamic through its ability to change position. By adjusting the door angle, the system transforms the door's role from a static structural element to a dynamic functional component that adapts its purpose based on operational requirements.

AI summary
A laundry treatment apparatus may facilitate input and removal of laundry items. The laundry treatment apparatus may include a door which may selectively open and close an opening into a receiving space formed in a cabinet in which laundry items may be received for treatment. The door may serve as a laundry guide when positioned at an angle relative to the cabinet so as to guide laundry items into the receiving space, and may serve as a shelf to support laundry items thereon when positioned at another angle relative to the cabinet.
