Clip-On Strainer Design for Adaptable Solid-Liquid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen devices for separating solid and liquid food products do not provide a convenient means to attach selectively to existing containers like pans, pots, or bowls, limiting their effectiveness in separating liquids from solids.
Innovation Solution
A strainer device with a strainer component and attachment component that can be securely attached to the side of a container, featuring a surface with holes for liquid passage and a biasing band for contour conformity, along with clip members for secure attachment, allowing for efficient separation of solid food products from liquids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate strainer and container are used, then separation function is provided, but convenience and versatility are reduced
Solution Approach 1:
The patent combines the strainer and container into a single integrated device, where the strainer is permanently attached to the container. This merging provides both the separation function of the strainer and the containment function of the container simultaneously, improving ease of operation while maintaining versatility through the integrated design.
Solution Approach 2:
The integrated strainer-container device serves multiple functions: it acts as both a straining device and a collection container. The container can hold the separated liquid while the strainer retains solids, providing multi-functionality that enhances both convenience and versatility in kitchen operations.
2Adaptability or versatility
If integrated strainer-container device is used, then convenience and versatility are improved, but device complexity increases
Solution Approach 1:
By merging the strainer and container into a single integrated unit, the patent reduces the number of separate components that need to be handled, assembled, and cleaned. This integration simplifies the overall system while providing versatile functionality, effectively managing device complexity.
3Reliability
If fixed attachment is used, then secure attachment is achieved, but adaptability to different container sizes is reduced
Solution Approach 1:
The patent employs a flexible biasing band instead of a rigid fixed attachment. The biasing band can dynamically adjust its shape and size to conform to different container rims while maintaining secure attachment through elastic tension. This dynamic design provides both reliable attachment and adaptability to various container sizes.
Solution Approach 2:
The biasing band changes its physical parameters (shape, size, curvature) to match different container dimensions. By allowing the attachment mechanism to change its geometric parameters, the device achieves secure attachment across multiple container sizes and shapes without requiring multiple specialized attachments.
4Adaptability or versatility
If flexible biasing band is used, then adaptability to different container sizes is improved, but attachment security may be reduced
Solution Approach 1:
The flexible biasing band uses elastic dynamics to maintain secure attachment. As the band stretches and conforms to different container sizes, the elastic tension automatically adjusts to provide consistent holding force, ensuring reliable attachment regardless of container dimensions.
Solution Approach 2:
The patent uses a flexible biasing band (a flexible element) as the attachment mechanism. This flexible component can bend and stretch to match different container shapes while maintaining sufficient tension to secure the strainer firmly in place, achieving both adaptability and attachment security.

AI summary
A kitchen utensil or device, specifically a strainer, is constructed and adapted to attach removably to the side of a pan, pot, or bowl, to provide a convenient means to allow for the separation of solid food product from liquid. The strainer includes a generally planar top surface, having a plurality of small gauge holes, slits, or openings in its surface. The holes are effective to allow a liquid to pass through the surface of the utensil while retaining the solid food product. The device is attachable by a clip to the rim of an existing pan, pot, or bowl.
