Knife rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knife racks are difficult to clean due to dirt and mold accumulation within their slots, and existing designs that allow for easier cleaning, such as removable columns, can cause blades to stick to knives, especially when moist, leading to water marks.
Innovation Solution
A knife rack with a box body, top cover featuring long slotted holes, and round balls within the accommodating space for supporting knives, allowing for air circulation and water evaporation, along with ventilation holes and through holes for enhanced breathability and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If columnar objects are arranged in a box as a knife rack, then cleaning becomes easier, but the columns stick to the blades when moist, causing water marks
Solution Approach 1:
The patent uses spherical balls instead of columnar objects to support the knives. The spherical shape provides point contact with the blade surface, maximizing air circulation and water evaporation around the blade while minimizing surface area for moisture adhesion. This curvature-based approach prevents the sticking problem that occurs with flat or columnar surfaces.
Solution Approach 2:
The arrangement of spherical balls creates a porous structure with numerous gaps between them. These gaps function as channels for air circulation and water evaporation, allowing moisture to escape quickly from the blade surface. The porous configuration prevents water accumulation that would lead to sticking and water marks.
2Adaptability or versatility
If slots are provided in a box for inserting knives, then basic knife storage is achieved, but the slots are difficult to clean and accumulate dirt and mold
Solution Approach 1:
The patent replaces the traditional slot structure with multiple removable spherical balls arranged in the box. This segmentation allows each ball to be individually removed and cleaned, eliminating the difficult-to-reach slot interiors. The modular arrangement maintains knife storage capability while enabling easy access for cleaning.
Solution Approach 2:
The spherical balls are designed to be movable and removable from the box, transforming the static slot structure into a dynamic configuration. Users can easily remove and reposition the balls for cleaning or to adjust storage arrangements, providing both cleaning ease and storage versatility.
3Ease of operation
If columns are used to support knives, then knife placement is enabled, but air circulation is blocked and knives are difficult to dry
Solution Approach 1:
The spherical shape of the support balls creates multiple small contact points with the knife blade rather than a continuous surface. This curvature-based contact minimizes the barrier to air flow and allows water to evaporate quickly from all surfaces of the blade, significantly improving drying speed while maintaining stable knife placement.
Solution Approach 2:
The gaps between the spherical balls create a porous support structure that permits air circulation throughout the knife storage area. This porous configuration allows moisture to escape rapidly from the blade surfaces, accelerating the drying process while the balls provide adequate mechanical support for knife placement.
Applied Scientific Principles

AI summary
A knife rack includes a box body having a bottom, a plurality of peripheral walls surrounding the bottom, an accommodating space surrounded by the peripheral walls and the bottom and an opening provided where the accommodating space communicates with the outside, a top cover covering the opening and provided with a plurality of long slotted holes, and a plurality of round balls set within the accommodating space of the box body and used as a support structure for supporting knifes. The point-like contact between the round balls and the blades of stored knives can greatly reduce the contact area between the round balls and the blades, and the gaps between the round balls are conducive to air circulation.
