Oil Filter Tool With Interchangeable Collars for Multiple Sizes

Solution Overview

Problem

The need for multiple tools in different sizes to accommodate various oil filter sizes is costly and space-consuming, as described in Taiwanese Patent No. 294200.

Innovation Solution

An oil filter apparatus comprising a cover with an annular wall and multiple collars in different sizes, allowing a single tool to engage with and rotate oil filters of varying dimensions, including features like non-circular bosses and recesses for secure attachment and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tools in different sizes are prepared for oil filters of different sizes, then each oil filter size can be accommodated, but the cost and space requirements increase significantly

Engineering Contradiction:

Improvecompatibility with different oil filter sizesVSAvoidnumber of tools required

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The tool body is designed with a universal structure that can accommodate multiple oil filter sizes through the use of interchangeable collars. Instead of having separate tools for each filter size, a single tool body can perform multiple functions by accepting different collars that match different filter dimensions, thereby reducing the total number of tools needed while maintaining compatibility across all oil filter sizes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The tool is divided into modular components: a universal tool body and multiple detachable collars of different sizes. This segmentation allows the collars to be exchanged based on the specific oil filter size required, enabling one tool body to serve multiple purposes without requiring multiple complete tools, thus reducing both quantity and space requirements.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If a single tool is designed to accommodate multiple oil filter sizes, then the number of tools and space requirements are reduced, but the structural complexity increases

Engineering Contradiction:

Improvenumber of tools requiredVSAvoidstructural complexity of the tool

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The tool is divided into modular components: a universal tool body and multiple detachable collars of different sizes. This segmentation allows the collars to be exchanged based on the specific oil filter size required, enabling one tool body to serve multiple purposes without requiring multiple complete tools, thus reducing both quantity and space requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The collars act as intermediary components between the universal tool body and the various oil filter sizes. Each collar is designed with specific dimensional characteristics that match particular filter sizes, serving as a mediator that adapts the fixed tool body to different filter dimensions without requiring the tool body itself to be complex or variable.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multiple tools are used for different oil filter sizes, then each tool can be optimized for its specific size, but the cost increases significantly

Engineering Contradiction:

Improveperformance optimization for specific sizeVSAvoidnumber of tools required

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The tool body is designed with a universal structure that can accommodate multiple oil filter sizes through the use of interchangeable collars. Instead of having separate tools for each filter size, a single tool body can perform multiple functions by accepting different collars that match different filter dimensions, thereby reducing the total number of tools needed while maintaining compatibility across all oil filter sizes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

While the tool body maintains a universal design, the collars are customized with specific local qualities (dimensions, shapes, and features) that are optimized for particular oil filter sizes. This allows each collar to be precisely tailored to its intended filter size, ensuring reliable performance for that specific application while sharing the common, cost-effective tool body structure.

Inventive Principle:

Principle #3Local quality
