Anode Mount Assembly With Protrusion Recess Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sacrificial anodes require multiple assembly steps for installation and replacement, leading to significant time and cost in maintaining outboard motors and other devices in corrosive environments.
Innovation Solution
An anode mount assembly comprising a mount component made from non-corroding materials like stainless steel or aluminum, and an anode component with a more anodic material such as zinc or magnesium, featuring a cooperating protrusion and recess pair and a single fastening mechanism for quick and secure mounting/dismounting, reducing the number of fasteners needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sacrificial anodes are installed using multiple assembly steps and multiple fasteners, then the anode is securely mounted, but the installation and replacement time becomes excessively long (20-25 minutes per anode)
Solution Approach 1:
The anode assembly is divided into two separate components: a mount component that remains permanently attached to the device, and an anode component that can be quickly removed and replaced. This segmentation allows the permanent mounting structure to provide secure attachment while the replaceable anode portion enables rapid maintenance without requiring multiple fasteners to be removed.
Solution Approach 2:
The fastening mechanism is extracted from the anode component itself and placed in the mount component. The anode component includes a protrusion that engages with a recess in the mount, while the fastener is retained by the mount component. This extraction allows the anode to be removed by simply releasing the fastener from the mount, significantly reducing replacement time.
2Strength
If traditional sacrificial anodes use multiple fasteners for secure attachment, then the mounting is robust, but the number of assembly steps and fastening operations increases
Solution Approach 1:
The mounting system is segmented into a permanent mount component with integrated fastening features and a separate anode component with engagement features. This segmentation allows the mount to provide robust attachment through its recess and fastener while the anode simply needs to engage with these features, reducing the overall complexity of the assembly process.
Solution Approach 2:
The mount component acts as an intermediary between the device structure and the anode. It provides the recess that receives the anode protrusion and retains the fastener, thereby mediating the connection between the anode and the device. This intermediary structure simplifies the interface requirements for the anode while maintaining robust mounting.
3Reliability
If traditional anode installation requires multiple fasteners and assembly steps, then thorough attachment is achieved, but maintenance cost increases
Solution Approach 1:
By segmenting the anode system into a permanent mount and a replaceable anode component, the invention reduces maintenance costs. The mount component can be manufactured once and reused, while only the simpler anode component needs to be replaced during maintenance, reducing both labor and material costs compared to replacing entire complex assemblies.
Solution Approach 2:
The anode component is designed as a disposable or easily replaceable element that sacrificially protects the more valuable mount and device. Since the anode is consumed over time, designing it as a simple, low-cost component that can be quickly replaced is more economical than designing the entire assembly as a permanent, complex unit.

Function Achieved in This Case
This configuration allows for rapid and secure replacement of anode components, significantly reducing the time required for maintenance from approximately 40-45 minutes to under 10 minutes, thereby decreasing costs and complexity.
Implementation Method 1
Galvanic corrosion occurs when dissimilar materials are in contact with each other, and an electrical circuit is completed. Often, electrolytic solutions complete the electrical connection which causes galvanic corrosion. When dissimilar metals are in contact with each other in a 'galvanic series,' the more anodic material (i.e. the material with a higher tendency to sacrifice electrons in a galvanic series) will preferentially sacrifice electrons for the less anodic (or more cathodic) material.
Implementation Method 2
Electrolytic solutions, which provide mobile charge carriers for the conduction of electrical current, are often provided by water, such as salt water, pond water, or other such solutions.

AI summary
An anode mount assembly is provided for facilitating rapid replacement of an anode component. The adapter mount assembly can comprise a mount component comprising a component body having at least one mounting aperture disposed therein and at least one protrusion or recess that can engage a recess or protrusion of the anode component for restricting movement of the anode component with respect to the mount component in at least one of a rotational and a translational direction of movement. Further, the anode component can comprise an engagement aperture, and the mounting aperture and the engagement aperture can be configured to receive a fastener for securing the anode component to the mount component and for restricting at least one additional degree of movement of the anode component with respect to the mount component to thereby secure the anode component to the mount component.
