Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air cleaners for internal combustion engines require complex processes for mounting adsorption filters, involving hooks and fusions, which complicates the mounting procedure.
Innovation Solution
An air cleaner design featuring a first and second housing with a guide groove and restriction portion system allows the adsorption filter to be easily inserted and securely mounted within the second housing, using elastic deformation to guide and retain the filter in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adsorption filter is fixed to the cap by hooking mounting holes to pins and fusing the pins, then the adsorption filter is securely retained, but the mounting process becomes complicated
Solution Approach 1:
The patent extracts the complex hooking and fusing operations from the mounting process. Instead of using pins that require hooking and fusing, the invention uses a simplified elastic deformation mechanism where the cap itself deforms to retain the adsorption filter, eliminating the need for separate fastening components and operations.
Solution Approach 2:
The cap performs the dual function of both guiding and retaining the adsorption filter through its own elastic deformation. The cap's wall elastically deforms during mounting to allow insertion, then automatically retains the filter without requiring external fastening mechanisms, making the system self-sufficient.
2Ease of operation
If the adsorption filter is mounted by inserting it into the second housing, then the mounting process is simplified, but the filter may fall off from the mounting position
Solution Approach 1:
The patent applies dynamics by using elastic deformation of the cap wall. The cap transitions from a rigid state during normal operation to a dynamic elastic state during mounting, allowing the filter to be inserted and then automatically retained when the elastic material returns to its original shape, providing both ease of mounting and secure retention.
Solution Approach 2:
The patent changes the physical parameter of the cap wall from rigid to elastically deformable during the mounting process. By controlling the elastic deformation parameter, the system allows easy insertion of the adsorption filter while maintaining secure retention through the restored elastic state, resolving the contradiction between mounting ease and retention reliability.
3Manufacturing precision
If guide portions are formed on inner faces of the second housing, then the adsorption filter is accurately guided to the mounting position, but the structure of the housing becomes more complex
Solution Approach 1:
The patent makes the cap wall serve multiple functions: it provides the housing structure, acts as the guide for the adsorption filter through its inner face, and simultaneously provides the elastic retention mechanism. This multi-functionality eliminates the need for separate guide components, maintaining mounting precision without increasing overall structural complexity.
Solution Approach 2:
The patent merges the guide function and retention function into the cap wall itself. The guide portions and elastic retention features are integrated into a single structural element, reducing the number of separate components and simplifying the housing structure while maintaining accurate guidance and secure retention of the adsorption filter.

Function Achieved in This Case
Facilitates accurate and easy mounting of the adsorption filter, ensuring stable retention and efficient fuel vapor absorption while minimizing interference with airflow and detection accuracy.
Implementation Method 1
a sheet-shaped adsorption filter that is arranged inside the second housing... The adsorption filter adsorbs fuel vapor that flows into the interior of the second housing through the outlet
Implementation Method 2
While movement of the adsorption filter to the mounting position is allowed by elastic deformation, the adsorption filter is restricted from falling off from the mounting position

AI summary
An adsorption filter for an air cleaner for an internal combustion engine is mounted by being inserted inside a second housing along a face of the adsorption filter. In an inner face of the second housing, the adsorption filter is guided to a mounting position in an inserting direction of the adsorption filter. While the movement of the adsorption filter to the mounting position is allowed by elastic deformation, the adsorption filter is restricted from falling off from the mounting position.
