Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional straining devices in cooking appliances face challenges in rapidly and reliably draining liquids while effectively separating and retaining solids, especially in steam cooking appliances, where clogging can occur due to large solid deposits, and require a visually appealing and easy-to-clean design.
Innovation Solution
A straining device with a straining body featuring multiple passages configured as embossments, which are designed to separate and retain solids from a solid-liquid mixture by forming a channel with the bottom wall for efficient liquid discharge, reducing clogging and allowing for easy cleaning and visually appealing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional straining devices with simple hole passages are used, then liquid can be drained, but solids can clog the passages and reliability decreases
Solution Approach 1:
The passage is segmented into two distinct types: holes for solid retention and embossments for liquid discharge. This segmentation allows each component to perform its specialized function - holes act as filters to prevent clogging by larger solids, while embossments provide additional liquid flow paths that are less prone to clogging, thereby resolving the contradiction between reliability and productivity.
Solution Approach 2:
Different regions of the straining body are given different local qualities - the holes provide filtering quality for solid retention, while the embossments provide high-flow quality for rapid liquid discharge. This local differentiation allows the system to simultaneously achieve both clogging prevention and high liquid discharge speed without compromising either function.
2Productivity
If multiple passages are added to increase liquid discharge speed, then productivity improves, but device complexity increases
Solution Approach 1:
The invention merges two different passage forms (holes and embossments) into a single integrated straining body structure. This combination allows multiple liquid discharge paths to be achieved without adding separate components or complex mechanisms. The embossments are formed directly on the straining body surface, creating additional flow channels while maintaining a relatively simple monolithic structure, thus improving productivity without proportionally increasing device complexity.
3Reliability
If the straining device is designed with complex passages to prevent clogging, then reliability improves, but ease of cleaning deteriorates
Solution Approach 1:
By segmenting the passage system into holes and embossments, the design achieves clogging prevention through the filtering action of holes while the embossments maintain simpler, more open geometries that are easier to clean. The segmented approach allows each element to be optimized for its specific function - filtration for holes and high-flow/cleanability for embossments - thereby improving reliability without sacrificing ease of cleaning.
