Filter housing and air-circulating electric roaster including same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-circulating electric roasters face issues with fine odors being emitted to the outside and internal contamination due to oil molecules adhering to the intake passage and fan, necessitating frequent cleaning and the use of porous material members that require fixing parts, which are inconvenient to install and maintain.
Innovation Solution
A filter member housing with detachable and self-fixing components, comprising a first and second member with protrusions and grooves, allowing easy assembly and disassembly without separate fixing parts, effectively capturing oil and odor molecules within the air-circulating electric roaster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If porous material members are used to capture oil and odor molecules, then the harmful factors are reduced, but the device complexity increases due to the need for fixing parts
Solution Approach 1:
The filter member housing is designed to be self-fixing through the elastic force of the filter member itself. When the filter member is inserted, its elastic force automatically secures it in position without requiring separate fixing parts. The filter member serves both its filtration function and the fixing function simultaneously.
Solution Approach 2:
The patent combines the filter member and the fixing mechanism into a single integrated component. The filter member housing structure merges the containment function with the self-fixing function, eliminating the need for separate fixing parts while maintaining both filtration and secure positioning.
2Stability of the object's composition
If the filter member is secured with fixing parts, then the stability is improved, but the ease of operation deteriorates due to installation and maintenance inconvenience
Solution Approach 1:
The filter member automatically secures itself through its elastic force when inserted into the housing. Users simply need to insert the filter member, and its elastic properties automatically engage it in the correct position, making installation trivial. Similarly, removal is simple by overcoming the elastic force, facilitating easy maintenance.
Solution Approach 2:
The patent extracts the fixing function from separate fixing parts and integrates it into the filter member itself through its elastic force. This eliminates the need for additional components, simplifying both installation and maintenance operations while maintaining stable positioning.
3Volume of moving object
If the housing structure is made compact to fit narrow spaces, then the volume is reduced, but the ease of manufacture worsens due to assembly complexity
Solution Approach 1:
The filter member's elastic force performs the assembly function automatically. When the filter member is inserted into the compact housing, its elastic force self-secures it in position, eliminating the need for complex assembly steps or additional fastening operations. This simplifies manufacturing despite the compact design.
Solution Approach 2:
The patent removes the need for separate assembly operations by integrating the fixing function into the filter member itself. The elastic force of the filter member replaces complex assembly mechanisms, allowing simple insertion and automatic securing in the compact housing structure.
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 filter member housing stabilizes the filter in a narrow space, minimizing contamination of the air intake passage and fan while maintaining smooth air circulation, and efficiently attenuates oil and odor without the need for additional fixing mechanisms.
Implementation Method 1
the protrusion is positioned at a first end of the groove by an elastic force of the filter member
Implementation Method 2
when the pressure is released, the protrusion returns to the first end of the groove by elastic recovery of the filter member

AI summary
A filter member housing includes a first member having a first opening at a first side along a first direction and a first space for accommodating a first side of a filter member, and a second member having a second opening at the first side for receiving the first side of the first member and a second space for accommodating a second side of the filter member and the first side of the first member. A portion of the first side of the first member is inserted into the first side of the second member, so that the filter member is received within a space defined by the first and second spaces. When a protrusion on the first member engages a groove on the second member, the protrusion is positioned at a first end of the groove by the elastic force of the filter member.
