Detergent Drawer Push-Lock Design for Stable Washer Control Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of front-loading laundry washing machines with a push-pull or push-push mechanism for detergent drawer extraction is inconsistent with the placement of the appliance control panel, leading to aesthetical and operational issues, as the detergent drawer may suddenly extract when pressing buttons on the control panel.
Innovation Solution
A laundry washing machine design featuring a drawer-like supporting structure that can move between retracted and extracted positions, with a locking mechanism and push member to facilitate controlled extraction of the detergent drawer and control panel, ensuring the panel remains coplanar with the front wall during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push-pull or push-push mechanism is used to facilitate detergent drawer extraction, then ease of operation is improved, but reliability deteriorates due to unintended extraction when pressing control panel buttons
Solution Approach 1:
The push member is divided into two functional segments: a first portion that interacts with the locking mechanism and a second portion that interacts with the detergent drawer. This segmentation allows the push member to perform different functions at different stages, first releasing the lock and then pushing the drawer, thereby preventing unintended activation while maintaining ease of operation
Solution Approach 2:
The locking mechanism is designed to be released before the push member can push the detergent drawer. This preliminary action sequence ensures that normal button presses on the control panel cannot accidentally trigger drawer extraction, as the locking mechanism remains engaged until intentionally released by the user through the designated release mechanism
2Ease of operation
If the detergent drawer is allowed to move freely for easy extraction, then ease of operation is improved, but stability deteriorates causing aesthetic misalignment with the front wall
Solution Approach 1:
The locking mechanism provides a preliminary restraining force that prevents the detergent drawer from moving until it is intentionally released. This anti-action counteracts the push member's force during normal operation, ensuring the drawer remains stable and coplanar with the front wall, while still allowing easy extraction when the lock is released
Solution Approach 2:
The system transitions from a static locked state to a dynamic extracted state through a controlled mechanism. The locking mechanism and push member work together to create a dynamic system that is stable in the retracted position but easily movable to the extracted position when needed, maintaining aesthetic alignment during normal operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for safe and user-friendly operation by preventing unintended extraction of the detergent drawer during control panel button presses, maintaining the panel's stability and aesthetic alignment with the front wall.
Implementation Method 1
a push member (18) which is able to elastically push the drawer-like supporting structure (13) away from the retracted position and towards the extracted position

AI summary
A laundry washing machine (1) includes an outer casing (2) and an appliance control panel (6) located on a front wall (3) of the casing (2). The appliance control panel (6) is arranged on a front side of a drawer-like supporting structure (13) which is inserted in extractable manner into a corresponding drawer housing (14). The drawer-like supporting structure (13) is movable inside the drawer housing (14) between a retracted position and a completely extracted position. The laundry washing machine (1) furthermore includes: a push member (18, 33) which is able to elastically push the drawerlike supporting structure (13) away from the retracted position and towards the completely extracted position; a locking mechanism (19) for automatically holding the drawer-like supporting structure (13) in the retracted position and to prevent the push member (18, 33) from pushing the drawer-like supporting structure (13) away from the retracted position; and a manually operated command device (20) for forcing the locking mechanism (19) to release the drawerlike supporting structure (13), thus allowing the push member (18, 33) to push the drawer-like supporting structure (13) away from the retracted position.
