Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil filter removal tools face difficulties in gripping and removing filters in tight locations and fail to effectively manage spilled oil during the process.
Innovation Solution
An oil filter removal tool with a cavity, reverse threads for secure grip, and a lip to capture spilled oil, along with a wrench connection for easy use with a socket wrench, allowing for efficient removal and containment of oil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional oil filter removal wrenches are used, then the filter can be removed, but they cannot fit or be easily used in tight locations
Solution Approach 1:
The oil filter removal tool features a cavity that receives and contains the oil filter during removal. The filter nests within the cavity, allowing the tool to accommodate the filter in a compact configuration that enables access to tight locations while maintaining the removal function.
Solution Approach 2:
The tool transitions from a traditional linear wrench design to a three-dimensional cavity structure that envelops the filter. This dimensional change allows the tool to fit in tight spaces by utilizing vertical and radial space rather than requiring extensive linear access.
2Object-affected harmful factors
If traditional oil filter removal tools are used, then the filter can be loosened, but spilt oil is not captured
Solution Approach 1:
The cavity that receives the oil filter also serves to capture and contain spilled oil. The harmful effect of oil spillage is converted into a contained substance within the cavity, preventing it from contaminating the surrounding area while the filter is being removed.
Solution Approach 2:
The tool merges multiple functions into a single structure: the cavity both receives the filter for removal and simultaneously captures spilled oil. This consolidation eliminates the need for separate containment devices while maintaining both functions.
3Reliability
If reverse threads are used to grip the filter base, then secure grip is achieved, but the threading mechanism becomes more complex
Solution Approach 1:
The tool employs reverse (left-handed) threads instead of conventional right-handed threads to engage the filter base. This inversion of the standard threading direction provides enhanced grip security and prevents the filter from loosening during removal, while the threading mechanism itself remains a standard mechanical feature.
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
Enables secure grip and easy removal of oil filters in tight spaces while capturing spilled oil, accommodating various filter sizes and materials without the need for multiple tools, enhancing user convenience and cleanliness.
Implementation Method 1
The reverse threads grip the base of the oil filter when being turned to the left, and as they tighten onto the filter, they grip tighter and tighter
Implementation Method 2
a tapered base portion with reverse (e.g. left handed) threads for gripping the base of the oil filter
Implementation Method 3
As the filter comes loose, any spilt oil will be captured within the cavity of the removal tool
Data Source
AI summary
An oil filter removal tool with a cavity for receiving the oil filter, a tapered base portion with reverse (e.g. left handed) threads for gripping the base of the oil filter, and a lip for capturing spilled oil. A wrench connection below the base portion of the tool fits a typical socket wrench head to allow for easy removal of the oil filter using a common tool. The reverse threads grip the base of the oil filter when being turned to the left, and as they tighten onto the filter, they grip tighter and tighter and then begin to loosen the filter. As the filter comes loose, any spilt oil will be captured within the cavity of the removal tool.
