Magnetic Drain Pan for Vehicle Hub Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain pans for vehicle axles are difficult to position securely on the circular margin of a hub and are prone to movement or falling, making it cumbersome to collect lubricant oil during maintenance, especially due to the complexity of using multiple positioning bolts.
Innovation Solution
A drain pan design featuring a front wall, rear wall, bottom, cambered walls, and magnetic members that contact the circular margin of the hub for secure adhesion and positioning, allowing easy placement and removal without the need for additional positioning elements, and accommodating various hub sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drain pan with positioning holes and bolts is used to prevent movement, then the drain pan is secured to the hub, but the positioning process becomes complicated and time-consuming
Solution Approach 1:
The patent replaces the mechanical bolt-positioning-hole system with a magnetic field-based positioning system. The magnetic member embedded in the drain pan interacts with the ferromagnetic hub to provide secure positioning without requiring any mechanical fasteners, thereby eliminating the complexity of inserting and removing multiple bolts while maintaining reliable attachment.
Solution Approach 2:
The invention extracts and removes the positioning holes and bolts from the drain pan design. By eliminating these mechanical positioning elements, the patent simplifies the overall structure while maintaining secure positioning through the magnetic member alone, reducing both device complexity and the time required for positioning operations.
2Reliability
If multiple bolts are used for positioning the drain pan, then the drain pan is securely fixed, but the time required for positioning and removal increases
Solution Approach 1:
The magnetic positioning system replaces the time-consuming mechanical bolt insertion and removal process with a simple magnetic attachment and detachment operation. The magnetic member provides immediate secure fixing when the drain pan is placed on the hub, and allows equally quick removal by simply lifting the pan away, dramatically reducing the time required for both positioning and removal operations.
Solution Approach 2:
The magnetic member provides self-aligning and self-securing functionality. When the drain pan is brought near the hub, the magnetic force automatically guides and secures the pan in the correct position without requiring manual alignment or insertion operations, thereby reducing positioning time while maintaining reliable fixation.
3Ease of operation
If a simple drain pan without positioning mechanism is used, then the drain pan is easy to place and remove, but the drain pan may move or fall from the hub
Solution Approach 1:
The magnetic member provides secure positioning while maintaining ease of operation. The magnetic force automatically secures the drain pan to the hub when placed nearby, eliminating the need for complex mechanical positioning mechanisms. The pan can be easily removed by simply lifting it away, combining the ease of simple placement with the reliability of secure fixation.
4Reliability
If positioning bolts are used to secure the drain pan, then the drain pan is prevented from overturning, but the cleaning of leaking lubricant oil becomes troublesome
Solution Approach 1:
By removing the positioning holes and bolts from the design, the patent eliminates the sources of lubricant oil leakage and contamination. Without holes and bolt interfaces, there are fewer places for oil to leak and less debris to clean, making the maintenance process easier while the magnetic member continues to provide reliable overturning prevention.
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 drain pan is easily positioned and secured to the hub using magnetic force, preventing overturning and leakage, simplifying the lubricant oil collection process while eliminating the need for complex bolt positioning and removal.
Implementation Method 1
The magnetic member is disposed on a face of one of the cambered walls opposite to the receiving room and has a predetermined area. When the drain pan is to be positioned to the circular margin of the hub, each cambered wall and the magnetic member contact the circular margin of the hub for adhesion.

AI summary
A drain pan for vehicle axle is adapted for being positioned to a circular margin of a hub. The drain pan includes a front wall, a rear wall, a bottom connecting the front wall and the rear wall therebetween, two lateral walls connecting the front wall and the rear wall therebetween, two cambered walls connecting the bottom and the lateral walls therebetween, and at least one magnetic member. The magnetic member is disposed on an outer surface of the one of the cambered walls. Each cambered wall and the magnetic member contact the circular margin of the hub for positioning the drain pan onto the circular margin by magnetic force. Thereby, the drain pan can be positioned quickly, and the drain pan is able to be utilized on hubs in various sizes.
