Dishwasher and conveying system therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher designs with elevateable racks require users to uncomfortably reach under the rack for maintenance tasks, risking damage to the dishwasher door and compromising user-friendliness.
Innovation Solution
A conveying system that allows the rack to be positioned in an intermediate state, creating a space between the rack and the dishwasher's aperture for easier access, and includes a locking mechanism to prevent displacement due to loaded items, ensuring the rack remains stable during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rack is allowed to reach full elevated position, then loading/unloading comfort is maximized, but the door hinges may break due to user weight when leaning on the door for support
Solution Approach 1:
The rack positioning system is designed to be dynamically adjustable, allowing the rack to be positioned at optimal heights for loading/unloading without requiring it to be permanently fixed at the maximum elevated position. This reduces the need for users to lean on the door for support.
Solution Approach 2:
The conveying system acts as an intermediary mechanism that provides smooth, controlled movement of the rack. This eliminates sudden shifts or instability that could cause users to lose balance and lean on the door, thereby protecting the hinges from excessive stress.
2Stability of the object's composition
If a locking mechanism is added to prevent rack displacement, then rack stability is improved, but device complexity increases
Solution Approach 1:
The conveying system incorporates automatic locking mechanisms that engage and disengage based on the rack's position. The system serves itself by using the rack's own weight and position to trigger the locking action, eliminating the need for separate manual locking operations or complex control systems.
Solution Approach 2:
The locking mechanism is designed to use simple mechanical elements such as springs, latches, or cam-based systems rather than complex electronic or hydraulic locking systems. This maintains rack stability while minimizing the addition of complexity to the overall conveying system.

AI summary
A conveying system for conveying a rack of a dishwasher between a displaced position and a start position along a path as well as a dishwasher including the conveying system are disclosed. In the displaced position, the rack may be displaced with respect to the start position in at least a first direction perpendicular to a main extension plane of the rack. An elevating arrangement may bias the rack towards the displaced position when the rack is located at a portion of the path. A locking arrangement may releasably lock the rack in an intermediate position between the displaced position and the start position when the rack is located at the portion of the path, thereby preventing the rack from being biasedly retracted to the displaced position or preventing the rack from being displaced away from the intermediate position due to weight of articles carried by the rack.
