Dish Drying Mat With Ribs, Dimples, and Drainage Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dish drying mats made of fluid-impervious materials trap water under the mat, leading to unevaporated dishwater and difficulty in cleaning due to sharp corners and creases that can harbor bacteria.
Innovation Solution
A dish drying mat with integrally molded ribs and dimples that are spaced apart and feature rounded transitions, allowing for easy cleaning and moldability, with a design that facilitates evaporation of water through atmospheric communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mat is made of fluid-impervious material, then water resistance is improved, but water accumulates under the mat and cannot evaporate
Solution Approach 1:
The mat incorporates a layer of porous material that allows water to pass through while maintaining fluid imperviousness on the surface. This enables water to drain through the mat rather than accumulate underneath, resolving the contradiction between water resistance and water accumulation prevention.
2Ease of operation
If raised ribs are added to elevate dishes, then drying effectiveness is improved, but sharp corners are created that are difficult to clean and harbor bacteria
Solution Approach 1:
The raised ribs are designed with rounded contours and curved surfaces instead of sharp corners. This curvature maintains the elevation function for effective drying while eliminating crevices where bacteria could accumulate, making the surface easier to clean.
3Adaptability or versatility
If complex rib and dimple structures are added, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple functional elements (ribs for elevation, dimples for water collection, drainage channels) are integrated into a single molded structure. This combining of functions into one component achieves high versatility while simplifying manufacturing through a single production process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mat effectively prevents water accumulation, is easy to clean, and maintains hygiene by avoiding sharp corners, while being easily moldable from thermoplastic materials.
Implementation Method 1
The gap communicates this lower space to the atmosphere, permitting any water finding its way therein to evaporate

AI summary
A dish drying mat has elongate spaced-apart ribs upwardly extending from a general upper surface, and spaced-apart dimples downwardly extending from a general lower surface. The lateral locations of the ribs and the dimples do not intersect. A lower portion of a marginal wall has at least one gap so as to communicate a continuous lower volume below the general lower surface to the atmosphere beyond the peripheral margin of the mat. At rounded corners, the peripheral wall has inwardly concave surfaces which are sized to fit to a thumb or finger of a user's hand when grasping or cleaning the mat.
