Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sieve baskets face issues such as residual water accumulation, increased risk of injury due to rough surfaces, and complex manufacturing processes, which hinder efficient sterilization and disinfection of medical objects.
Innovation Solution
A procedure for producing a three-dimensional perforated plate sieve basket, where the bridges between holes are deformed to create a corrugated structure, mimicking the spatial structure of a wire mesh without the need for actual wire mesh, thereby enhancing drainage and preventing object slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat perforated sheet base is used, then manufacturing is simple and cost-effective, but residual water accumulates through capillary action causing disruptive dampness
Solution Approach 1:
The patent transforms the flat two-dimensional base into a three-dimensional corrugated structure by deforming the bridges between holes. This dimensional change creates surface topology that prevents capillary action while maintaining manufacturing simplicity through sheet metal forming processes.
Solution Approach 2:
The patent introduces curved surfaces through corrugations formed by deforming the bridges between holes. These curved surfaces disrupt the flat plane that causes capillary action, allowing water to drain more effectively while maintaining structural integrity.
2Object-generated harmful factors
If a wire mesh is used to prevent object slippage, then drainage improves, but the risk of injury increases due to broken wires and protruding objects
Solution Approach 1:
The patent creates a visual and functional copy of wire mesh structure using a perforated sheet base with deformed bridges. The corrugated pattern mimics the spatial structure of wire mesh, providing similar drainage and anti-slip properties without the actual wire components that pose injury risks.
Solution Approach 2:
The patent uses a perforated sheet metal base with optimized hole patterns and deformed bridges to create a porous structure that facilitates drainage. The porous configuration allows fluid passage while maintaining structural strength and eliminating sharp edges that could cause injury.
3Ease of manufacture
If the base surface is made flat to simplify manufacturing, then production costs are reduced, but contact area with objects increases causing dampness
Solution Approach 1:
The patent reduces the effective contact area by introducing vertical dimension through corrugations. The deformed bridges create peaks and valleys that minimize the flat surface area in contact with objects, thereby reducing capillary action and dampness while maintaining manufacturing simplicity.
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 solution enables the mass production of sieve baskets that quickly drain, are compactly loaded, and have a reduced risk of injury, while also simplifying the manufacturing process and reducing costs.
Implementation Method 1
The flat base surface creates contact between the objects held in the sieve basket and the floor, corresponding to the remaining width of the gaps between the plate holes. This contact causes residual water to collect through capillary action
