Outboard Motor Support Reinforcement for Lateral Load Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outboard motors require increased size or weight of the support member to enhance mechanical strength against lateral loads, which is inefficient and undesirable.
Innovation Solution
The outboard motor design incorporates left and right reinforcement members that connect to the support member, allowing for efficient distribution of lateral loads from the propulsion unit to the hull, thereby increasing mechanical strength without increasing the size or weight of the support.

Engineering Contradiction Analysis
1Strength
If the size or weight of the support member is increased to enhance mechanical strength against lateral loads, then the mechanical strength is improved, but the device complexity and weight increase
Solution Approach 1:
The support member is divided into multiple components: the main support body, left reinforcement member, and right reinforcement member. These segmented components work together to distribute and resist lateral loads, achieving enhanced mechanical strength without requiring a single oversized support structure.
Solution Approach 2:
The reinforcement members extend laterally beyond the left and right sides of the support member, utilizing the horizontal dimension to create a wider load distribution structure. This dimensional extension allows lateral loads to be dispersed over a broader area, improving strength without increasing vertical height or overall compactness.
2Strength
If the size of the support member is increased to enhance mechanical strength against lateral loads, then the mechanical strength is improved, but the device occupies more space
Solution Approach 1:
The support structure is segmented into a compact main support body and extended reinforcement members. This segmentation allows the load-bearing function to be distributed across multiple components, achieving high mechanical strength while maintaining a compact overall footprint.
Solution Approach 2:
The reinforcement members utilize the lateral horizontal dimension efficiently by extending just beyond the support's left and right sides. This strategic dimensional extension provides enhanced load distribution while minimizing the overall area occupied, avoiding excessive spatial consumption.
3Strength
If reinforcement members are added to distribute lateral loads, then the mechanical strength is improved, but the device complexity increases
Solution Approach 1:
The support system is segmented into distinct functional components (main support, left reinforcement, right reinforcement), each with a specific role in load distribution. This segmentation simplifies the design and analysis of each component while achieving complex load-bearing performance through their coordinated arrangement.
Solution Approach 2:
The left and right reinforcement members are positioned asymmetrically relative to the main support body, extending beyond the left and right sides respectively. This asymmetric arrangement optimizes the distribution of lateral loads from the propulsion unit, providing enhanced mechanical strength with a relatively simple structural configuration.

AI summary
An outboard motor includes an attachment attached to a hull, and a support vertically rotatably connected to the attachment and horizontally rotatably supporting an outboard motor main unit. The support includes an upper support and a lower support. The outboard motor includes a left reinforcement that includes a left upper connector connected to the upper support and a left lower connector connected to the lower support, and a right reinforcement that includes a right upper connector connected to the upper support and a right lower connector connected to the lower support. The left upper connector is located leftward of a left side of the upper support. The right upper connector is located rightward of a right side of the upper support.
