Fryer Filter Bowl Layout for One-Handed Oil Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric fryer designs face challenges in facilitating easy and ergonomic filtration of the cooking bath, often requiring precise manipulations and using both hands, which can lead to confusion between gripping members and safety issues.
Innovation Solution
The design features an elongated gripping member for the receptacle and another elongated gripping member for the filtration element, with the latter extending below and closer to the tank, allowing for one-handed operation and improved safety, along with a filtration element forming a bowl with edges close to the tank walls for enhanced debris retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gripping member extends inside the tank close to a side wall for removing the filtration element, then the filtration element can be removed independently of the heating element, but the arrangement does not allow easy removal of the filtration element
Solution Approach 1:
The gripping member is repositioned from an internal arrangement close to the side wall to an external arrangement on the upper edge of the tank. This dimensional change allows the gripping member to extend outward, providing easy access for one-handed operation while maintaining the ability to remove the filtration element independently.
2Reliability
If two grippers are arranged close to opposite side walls with upper ends extending outside the tank for removing the filtration element, then the filtration element can be removed independently, but both hands are required and the arrangement proves insufficiently ergonomic
Solution Approach 1:
The design extracts the essential gripping function from a complex two-gripper system and consolidates it into a single elongated gripping member positioned on the upper edge of the tank. This extracted solution maintains independent removal capability while enabling one-handed operation, significantly improving ergonomics.
Solution Approach 2:
The single gripping member is designed to be universally applicable for removing both the receptacle and the filtration element independently. By positioning it on the upper edge of the tank with elongated structure, it serves multiple removal operations with one component, eliminating the need for separate grippers.
3Reliability
If gripping members are arranged close to side walls for removing filtration element, then filtration can be performed, but confusion may occur between gripping members of receptacle and filtration device
Solution Approach 1:
The gripping member is positioned at a distinct location on the upper edge of the tank, separate from any receptacle gripping features. This localized positioning creates clear spatial differentiation, allowing users to easily distinguish between the filtration element gripper and receptacle handling areas, eliminating confusion.
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
This configuration simplifies the filtration process, reduces the risk of confusion between gripping members, and enhances safety by allowing one-handed operation and effective debris retention, facilitating both cooking and filtration operations.
Implementation Method 1
immersion electric heater arranged in the tank below the receptacle and above the filtration element
Implementation Method 2
filtration element arranged in said tank under the food receptacle

AI summary
The apparatus has a vat (1) for receiving a cooking bath, and a receptacle (2) for receiving foods. The receptacle is arranged in the vat in a removable manner, and is associated to a gripping body (10) extending at the exterior of the vat. A filtering element (3) forming a bowl is arranged in the vat in a removable manner. The filtering element is associated to another gripping body (11) extending at the exterior of the vat. The latter gripping body extends outside the vat below an upper edge of the vat and remote from the former gripping body.
