Sliding Tine Holder Dishwasher Rack for Flexible Dish Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwasher racks have restricted tine movement, making it difficult to securely store dishes of various sizes and shapes, and are not compatible with altered rack shapes, leading to increased manufacturing costs and time.
Innovation Solution
A dishwasher rack with a movable rack installation structure that includes adjustable tines and a movable rack system, allowing for free adjustment of tine angles and range of movement, enabling secure storage of diverse dish sizes and shapes without the need for new components when the rack shape changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tine receiving portion and movable tine are respectively fixed to the rack frame, then the structure is simple and stable, but the range of movement is restricted and cannot accommodate various sizes and shapes of dishes
Solution Approach 1:
The patent implements a dynamic movable rack installation structure where the tine holder can slide along the rack frame and the movable tine can rotate within the tine holder. This dynamic design allows the tines to adjust their position and angle according to the size and shape of dishes, resolving the contradiction between structural simplicity and adaptability to various dish dimensions.
Solution Approach 2:
The movable rack installation structure is divided into separate functional components: the rack frame, the sliding tine holder, and the rotating movable tine. This segmentation allows each component to perform its specific function independently while working together to provide adjustable dish storage, enabling versatility without requiring complete structural redesign.
2Adaptability or versatility
If tine receiving portion and movable tine are designed with fixed dimensions suitable for the rack frame, then manufacturing is straightforward, but compatibility with altered rack shapes is lost and manufacturing cost increases
Solution Approach 1:
The movable rack installation structure is designed as a universal system where the tine holder and movable tine can be used across different rack frame configurations. The sliding and rotating mechanisms allow the same components to adapt to various rack shapes and sizes, eliminating the need to manufacture different tine assemblies for different rack designs, thereby reducing manufacturing cost and time while maintaining compatibility.
3Ease of operation
If movable tine is received in recess of tine receiving portion, then the structure is stable, but the angle and range of movement are restricted
Solution Approach 1:
The patent replaces the fixed recess structure with a dynamic system where the movable tine rotates within the tine holder and the tine holder slides along the rack frame. This dynamic design provides a wider range of movement while maintaining stability through the controlled mechanical connections between components, allowing dishes of various sizes to be securely positioned.
Solution Approach 2:
The tine holder acts as an intermediary component between the rack frame and the movable tine. It provides a sliding connection to the rack frame and a rotating connection for the movable tine, mediating between the fixed rack structure and the need for adjustable tine positioning. This intermediary structure enables both movement and stability.

AI summary
A dishwasher rack is provided. The dishwasher rack includes a tine holder, a tine holder moving portion, and/or a movable rack moving portion. The tine holder includes a plurality of portions formed to receive a holding tine for adjusting a gap between the holding tine and a structure opposite to the holding tine, according to a received position of the holding tine. The tine holder moving portion changes a position of the tine holder with respect to the rack frame. The movable rack moving portion changes a position of the movable rack with respect to the rack frame.
