Pivoting Dish Rack Holder with Positive Locking for Versatile Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dish rack holders in household dishwashers lack versatility and secure support for items like baking trays, which limits their functionality and efficiency in washing cycles.
Innovation Solution
A pivotally attachable holder with a holding element that can be locked in place on a vertical axis, allowing items to be securely supported from all sides, featuring a fastening element that provides a positive connection for stable support and can be easily released for folding when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a holder is rigidly fixed to the side wall, then stability and support strength are improved, but versatility and adaptability are worsened
Solution Approach 1:
The holder is designed with a pivoting mechanism that allows it to rotate between a folded position (parallel to side wall) and a holding position (protruding into receiving volume). This dynamic configuration enables the holder to adapt its support strength and positioning based on operational needs, resolving the contradiction between fixed stability and adaptive versatility
2Adaptability or versatility
If a holder protrudes into the receiving volume to support items, then support functionality is improved, but available space is worsened
Solution Approach 1:
The holder can be pivoted into a folded position where it remains parallel to the side wall and does not protrude into the receiving volume, maximizing available space. When support functionality is needed, it pivots to the holding position. This dynamic positioning resolves the contradiction between support functionality and space utilization
3Adaptability or versatility
If a holder is designed to be pivotally attached for versatility, then adaptability is improved, but reliability of locking is worsened
Solution Approach 1:
The holder includes a positive locking mechanism with a locking element that automatically engages with a locking position on the fastening element when the holder pivots to the holding position. This preliminary locking action ensures reliable fixation before any washing cycle begins, resolving the contradiction between pivotable adaptability and locking reliability

AI summary
The invention relates to a holder (23, 24, 26, 27) for holding washware (28) in a dish rack (16) of a domestic dishwasher (1), having a holding element (30), which can be fastened on a side wall (19) of the dish rack (16) such that it can be pivoted about a vertical axis (V) in a first pivoting direction (R1) and a second, opposing pivoting direction (R2) and which is designed so that, in a holding position (H) for holding the washware (28), it blocks pivoting in the first pivoting direction (R1) and in the second pivoting direction (R2), wherein, in the holding position (H), the holding element (30) has been pivoted away from the side wall (19).
