Modular Lower Rack Design for Dishwasher Container Bottom Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional domestic dishwashers with lower-rack raising mechanisms often prevent access to the container bottom due to the fixed connection of the lower rack, making maintenance, inspection, and repair difficult.
Innovation Solution
A modular lower rack design featuring a removable lower rack element and a fixed frame, allowing the rack to be raised and lowered for improved access to the container bottom, with the removable element being easily detachable for unobstructed access to the container bottom.

Engineering Contradiction Analysis
1Ease of operation
If a removable lower rack element is introduced, then access to container bottom is improved, but device complexity increases
Solution Approach 1:
The lower rack transitions from a static fixed structure to a dynamic configurable structure. The removable lower rack element can be easily attached and detached, allowing the rack configuration to adapt to different operational needs. This dynamic design enables simple access for maintenance while maintaining full functionality for normal operation, without requiring complex mechanisms.
