Rotating Fender Mounting Assembly for Boat Dock Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushioning devices, such as air-filled bolsters, are not effective in providing adequate cushioning and protection between objects, particularly in boat docking systems, where they fail to absorb impact forces and prevent contact between boats and docks effectively.
Innovation Solution
A fender mounting assembly is designed to attach fenders to slip walls, featuring a backing plate and a branch with multiple sections that extend to hold the fender at a predetermined distance, allowing it to rotate freely and absorb impact forces, thereby preventing contact between boats and docks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air-filled bolsters are used as cushioning devices, then the structure is simple and easy to manufacture, but they fail to provide adequate cushioning and protection, unable to absorb impact forces effectively
Solution Approach 1:
The mounting assembly is divided into distinct functional segments: a backing plate for wall attachment, a branch structure with multiple sections for positioning, and a fender component for cushioning. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The branch structure incorporates rotational freedom, allowing the fender to rotate and absorb impact forces dynamically. This dynamic capability enables the simple fender design to achieve reliable cushioning performance by adapting to impact directions.
2Reliability
If a rigid mounting structure is used to securely attach fenders, then the fenders are firmly fixed to slip walls, but they cannot rotate freely to absorb impact forces
Solution Approach 1:
The mounting assembly transitions from a static rigid structure to a dynamic system where the branch can rotate relative to the backing plate. This rotational freedom allows the structure to absorb impact forces while maintaining secure attachment to the slip wall.
Solution Approach 2:
The system changes its structural parameters during operation - remaining rigid during normal conditions but allowing rotational movement during impact events. This parameter change enables both secure mounting and effective cushioning.
3Reliability
If the fender is positioned close to the slip wall, then the mounting structure is compact, but it cannot effectively prevent contact between boats and docks
Solution Approach 1:
The branch structure provides localized extension at the critical position where the fender needs to be positioned. Rather than extending the entire mounting structure uniformly, only the necessary section is extended to achieve the predetermined distance for effective contact prevention.
4Adaptability or versatility
If a simple single-section branch is used to hold the fender, then the mounting assembly is simple to manufacture, but it cannot provide both upward and downward fender support configurations
Solution Approach 1:
The branch is segmented into multiple sections that can be configured in different orientations. This segmentation allows the same basic structure to accommodate both upward and downward fender support configurations without requiring completely different designs.
Solution Approach 2:
The multi-section branch structure serves multiple functions: it provides structural support, enables rotational movement, and can be configured for different mounting orientations (upward and downward). This multi-functionality achieves versatility without proportionally increasing complexity.

AI summary
A fender mounting assembly includes a backing plate and a branch. The backing plate is configured to attach to a slip wall to mount the fender mounting assembly to the slip wall. The branch is configured to hold a fender a predetermined distance away from the slip wall. The branch extends from the backing plate and includes a first section and a second section. The first section has a first end and a second end. The first end is attached to the backing plate. The second section has a third end and a fourth end. The third end is attached to the second end of the first section. When the fender mounting assembly is attached to the slip wall in an upright position via the backing plate, the second section of the branch extends downwardly from the first section of the branch.
