Oil Filter Mounting Adapter Camrod Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil filter mounting adapters do not simplify the installation and removal of engine oil filters, often requiring significant torque and tools, and can damage filters during removal due to space constraints.
Innovation Solution
An oil filter mounting adapter with a camrod mechanism that allows for easy attachment and detachment of the oil filter by hand, using low torque, and includes a nipple and camrod system that translates to draw the filter toward the adapter face, eliminating the need for a filter wrench.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional filter wrenches are used to remove oil filters, then the seal can be broken and filter removed, but considerable torque is required and space constraints make accessing the filter difficult
Solution Approach 1:
The clamp mechanism transitions from a static clamped state during filtering to a dynamic release state during removal. The release tool engages with the clamp to dynamically alter its gripping force, allowing easy filter removal without excessive torque by converting the static clamp into a controllable dynamic element.
Solution Approach 2:
The release tool acts as an intermediary between the user and the clamp mechanism. Instead of directly applying torque to the filter, the user operates the release tool which then mediates the clamp's action, reducing the force requirement by an order of magnitude through this intermediate mechanism.
2Ease of operation
If traditional filter wrenches are used to remove oil filters, then the filter can be removed, but the oil filter may be damaged during an attempted removal
Solution Approach 1:
The clamp's dynamic release mechanism allows controlled reduction of gripping force. As the release tool is operated, the clamp gradually releases its grip on the filter, preventing sudden movements or excessive forces that could damage the filter, while still maintaining secure holding during normal operation.
Solution Approach 2:
The clamp mechanism is designed with inherent cushioning characteristics that prevent abrupt release. The mechanical design provides a gradual release path that cushions the filter against sudden force changes, protecting it from damage during the removal process while maintaining strong attachment during use.
3Adaptability or versatility
If sandwich adapters or offset-type adapters are used, then connection with sensors or cooling kits is enabled, but they do not address the difficulties with filter installation and removal
Solution Approach 1:
The adapter merges two previously separate functions: the connection interface for sensors/cooling kits and the filter mounting interface with improved removal capability. By combining the clamp mechanism with the adapter body, it enables both versatility in connections and ease of filter operation simultaneously, resolving the contradiction between adaptability and ease of operation.

Function Achieved in This Case
Facilitates single-handed, tool-free installation and removal of oil filters with reduced torque requirements, enhancing accessibility and reducing the risk of filter damage.
Implementation Method 1
A camrod is engaged with the nipple, and rotation of the camrod creates a translation of the nipple which draws the oil filter toward a face of the adapter

AI summary
An oil filter mounting adapter includes a nipple for connecting an oil filter and a camrod engaged with the nipple. Rotation of the camrod produces a translation of the nipple which draws the oil filter toward a face of the adapter and seals the filter against the adapter. Rotation of the camrod requires only low torque, which simplifies removal and replacement of the oil filter. In embodiments, the camrod is positionable in a location which is easily accessible to the user. Embodiments include a detent which restricts motion of the camrod, and which may be released by hand.
