Dishwasher Door Connectors for Closed-Door UI Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers with multiple compartments lack an efficient mechanism for transforming between a single-door mode and a drawer mode, limiting user access and operational flexibility during different washing cycles.
Innovation Solution
A dishwasher design featuring a convertible door system that can transform between a full door mode and a drawer mode, allowing selective access to upper and lower compartments, facilitated by a transformation assembly and actuator assemblies that ensure proper alignment and locking mechanisms for fluid containment and treatment efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed single-door design is used, then the structure is simple, but user access flexibility to different compartments is limited
Solution Approach 1:
The door assembly is segmented into a first door portion and a second door portion that can move relative to each other. The second door portion is slidable along the first door portion, allowing independent access to upper and lower compartments. This segmentation enables the door to provide flexible access patterns while maintaining an integrated structure.
Solution Approach 2:
The door structure incorporates dynamic elements including a spring-loaded plunger mechanism and cam-based locking system. The plunger can be selectively positioned to engage with different cam surfaces, dynamically changing the door configuration between locked, unlocked, and partially unlocked states to provide various access modes.
2Adaptability or versatility
If a convertible door system with transformation assembly is implemented, then operational flexibility is improved, but device complexity increases
Solution Approach 1:
The transformation assembly merges multiple functions into a single integrated mechanism. It combines the door unlocking function, compartment sealing function, and access control function into one coordinated system that operates through a single user action, reducing the need for separate mechanisms for each function.
Solution Approach 2:
The plunger acts as an intermediary element between the user input and the door transformation system. It translates user activation into coordinated movement of the door portions and sealing elements, mediating the complex transformation sequence through a simple mechanical interface.
3Reliability
If data connectors are coupled only when closure element is closed, then data security is improved, but user interface accessibility is reduced
Solution Approach 1:
The data connector system transitions from a static connected state to a dynamic conditional connection state. The connectors are mechanically designed to engage only when the closure element is in the closed position, automatically establishing data communication between the controller and user interface only when the door is closed and sealed.
Solution Approach 2:
The door closure mechanism itself performs the function of establishing data connection. When the user closes the door, the mechanical movement automatically brings the data connectors into engagement, eliminating the need for a separate connection action and ensuring data security through the inherent positioning function of the closure element.

AI summary
A dishwasher may include a closure element, such as a door, a user interface on the closure element, and a controller. A data communication link having a first data connector may be coupled to the controller, and a second data connector may be coupled to the user interface. The first and second data connectors may communicatively couple when the closure element is in the closed condition to establish data communication between the controller and the user interface. The communication link may also form a power link to provide power to the user interface across an electrical link.
