Ship Deck Anchor Point Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor points for securing goods on ship decks are complex, require multiple parts, and often use expensive materials to withstand high loads, making them costly and difficult to mount and demount.
Innovation Solution
A simplified anchor point design where the lashing plate distributes loads directly to the deck, reducing the stress on attachment means, allowing for fewer and less expensive materials, and using a bayonet mount or permanent attachment for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional anchor points with multiple parts (screws, bricks, nuts) are used in wooden boards, then the anchor points can resist high loads, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple mounting steps (boring, screwing, fitting) and multiple parts (screws, bricks, nuts) into a single integrated anchor point component that can be installed in one operation, thereby reducing mounting complexity while maintaining load resistance
Solution Approach 2:
The anchor point is designed as a universal component that performs multiple functions: it provides load bearing capability, simplifies the mounting process, and can be easily removed and reinstalled, replacing the need for separate mounting hardware
2Ease of manufacture
If adhesive is used to fix lashing cups to wooden boards, then the mounting process is simplified, but the adhesive bond is insufficient to resist high lashing loads in demanding environments
Solution Approach 1:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical interlocking system where the anchor point is screwed directly into the wooden board, providing reliable mechanical attachment that can resist high lashing loads while maintaining ease of installation and removal
3Strength
If all components of the anchor point are made of high-strength materials to resist high lashing loads, then the load bearing capacity is sufficient, but the material cost increases significantly
Solution Approach 1:
The patent applies high-strength material properties only where absolutely necessary (in the load-bearing anchor point component itself), while allowing less expensive materials to be used in the mounting hardware and surrounding structure, thereby reducing overall material cost while maintaining sufficient load bearing capacity
4Strength
If anchor points with multiple parts and complex structures are used, then they can resist high loads, but the time required for mounting and demounting increases
Solution Approach 1:
The patent segments the anchor point into a single integrated component rather than multiple separate parts, allowing the entire anchor point to be mounted and removed as one unit, thereby significantly reducing the time required for installation and demounting while maintaining load resistance

AI summary
The object of the invention is achieved through an anchor point adapted to be mounted in a circular through hole in a board of a ship deck. The anchor point comprises an essentially circular lashing plate and an axial fixing means. The lashing plate is provided with a flange which is at least partially protruding outside the periphery of the through hole. Further, the lashing plate is provided with an opening in its upper surface in which a lashing hook can be arranged. The axial fixing means is adapted to be mechanical attached to the lashing plate through the through hole.
