Dishwasher Operating Module Pivot Mounting for Low-Force Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household dishwashers face challenges in ensuring secure and efficient sealing of the operating module, requiring high mounting force and multiple engagement sections during the mounting process.
Innovation Solution
The household dishwasher incorporates a pivoting operating module with a sealing element that engages positively with the panel box, reducing the mounting force required and ensuring a secure seal through a pivoting mechanism with fewer engagement sections, utilizing a plastic injection molded panel box and sealing element for effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear mounting procedure is used to secure the operating module, then the sealing tightness can be ensured, but high mounting force is required
Solution Approach 1:
The operating module is mounted using a pivoting movement instead of a linear insertion, transforming the static mounting process into a dynamic one. The module pivots from a dismounted state into a mounted state, allowing the sealing element to be progressively pressed between the panel box and the operating module, reducing the required mounting force while ensuring sealing tightness
Solution Approach 2:
The sealing element is designed to be pressed between the panel box and the operating module during the pivoting motion, changing the contact pressure parameter progressively. This allows the sealing tightness to be achieved with lower overall mounting force compared to linear insertion methods that require high force from the start
2Reliability
If multiple engagement sections are used to secure the operating module, then the sealing tightness is improved, but the device complexity increases
Solution Approach 1:
The pivoting mounting mechanism allows a single engagement section to achieve both positioning and sealing functions dynamically. As the operating module pivots into place, the engagement section secures the module while simultaneously pressing the sealing element, eliminating the need for multiple separate engagement sections that would be required in a static linear mounting system
Solution Approach 2:
The engagement section is combined with the sealing function in a single integrated mechanism. The same engagement section that secures the operating module also presses the sealing element between the panel box and the module, merging two functions (securing and sealing) into one component, thereby reducing the number of engagement sections needed

AI summary
A household dishwasher includes a dishwasher cavity, a door fastened to the dishwasher cavity and including a panel box, and an operating module provided on the door for operation of the household dishwasher and including a sealing element for sealing the operating module with respect to the panel box. The operating module is pivotable about an axis of rotation from a dismounted state, in which an engagement section of the panel box is not in positive-locking engagement with the operating module into a mounted state, in which the engagement section is in positive-locking engagement with the operating module and the sealing element is pressed between the operating module and the panel box.
