Foldable dish drying rack with removable utensil holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dish drying racks are often made from unsustainable materials that deteriorate over time, pose environmental concerns, and may scratch or stain ceramics, while lacking a practical solution for rapid utensil drying.
Innovation Solution
A foldable dish drying rack constructed from sustainable materials like bamboo, with a removable utensil tray and corrosion-resistant fasteners, designed to facilitate air drying by providing three-dimensional slots for various dish orientations and upright support for utensils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic is used for dish rack construction, then convenience is improved, but environmental sustainability deteriorates
Solution Approach 1:
The patent changes the material parameter from conventional plastic to bamboo, transforming the environmental sustainability characteristic while maintaining the functional convenience of a dish rack through thoughtful design of slots and drainage features
Solution Approach 2:
The patent employs composite construction by combining bamboo with metal fasteners and hardware, creating a hybrid structure that leverages the sustainability and non-scratching properties of bamboo while using metal for structural integrity and durability
2Duration of action of stationary object
If metal is used for dish rack construction, then durability is improved, but environmental cost and scratching/staining issues worsen
Solution Approach 1:
The patent changes the material parameter from metal to bamboo, eliminating the scratching and staining harmful factors while achieving comparable durability through bamboo's natural hardness and the structural design of the rack
Solution Approach 2:
The patent uses composite materials by combining bamboo with metal fasteners, where the metal components provide structural durability and connection strength without direct contact with dishes, thus avoiding scratching and staining while maintaining long-term durability
3Device complexity
If conventional fixed utensil holder is used, then structural simplicity is improved, but utensil drying efficiency deteriorates
Solution Approach 1:
The patent segments the utensil holder into a separate removable tray component with integrated drainage slots, allowing utensils to be positioned for optimal air circulation and water drainage, thereby improving drying efficiency while maintaining ease of use through the removable design
Solution Approach 2:
The patent adds a dimensional aspect to the utensil holder by incorporating elevated upright posts and three-dimensional slot structures that create multiple levels and angles for utensil placement, maximizing exposure to air flow and improving drying efficiency
4Stability of the object's composition
If non-foldable design is used, then structural stability is improved, but storage efficiency deteriorates
Solution Approach 1:
The patent introduces dynamic elements by incorporating pivot joints and hinged connections that allow the rack to transition between a stable unfolded configuration for use and a compact folded configuration for storage, thereby resolving the contradiction between structural stability and storage efficiency

AI summary
A foldable dish drying rack has a rack base section, a rack back section pivotally connected to the rack base section and a rack upright section pivotally connected to the rack base section rearward of the rack back section. The rack upright section supports the rack back section in an unfolded condition. A removable utensil tray has utensil tray support arms with utensil tray support arm notches that accept a top edge of base side members to support the utensil tray on either side of the rack base section when the dish drying rack is in the unfolded condition.
