Portable Marine Anchoring Device Using Segmented Stake and Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional marine anchors are heavy, create tripping hazards, and fail to effectively hold in sandy or loose soil conditions, making them unsuitable for temporary beach anchoring of small boats.
Innovation Solution
A portable, lightweight marine anchoring device with a hollow tube anchoring stake and a step plate, featuring an acute angle configuration and multiple plates that increase surface area and resistance, allowing for secure anchoring in sandy or uncompacted soil without increasing the anchor's size or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchors are used for beach anchoring, then anchoring capability is provided, but weight increases and tripping hazard is created
Solution Approach 1:
The anchor is divided into separate functional components: a lightweight stake portion for penetration and a plate portion for resistance. This segmentation allows each part to be optimized independently - the stake can be minimal weight while the plate provides necessary holding capacity through surface area, resolving the contradiction between anchoring capability and weight reduction.
Solution Approach 2:
The invention transitions from traditional three-dimensional anchor shapes to a two-dimensional plate configuration. The plate portion creates resistance through its surface area interacting with sand grains, effectively replacing the need for heavy three-dimensional anchor mass while maintaining anchoring capability and reducing weight.
2Reliability
If traditional anchors are used in sand, then anchoring is attempted, but holding capacity is insufficient
Solution Approach 1:
The plate portion is designed with specific local qualities - sufficient surface area to interact with sand grains, appropriate thickness for structural integrity, and material properties suited for sand penetration and resistance. This localized optimization of quality in the plate region provides adequate holding capacity specifically for sand conditions without requiring the entire anchor to be heavy.
3Strength
If anchor size is increased to improve holding capacity, then resistance against dislodgement increases, but weight and tripping hazard increase
Solution Approach 1:
Instead of increasing weight by volumetric expansion, the invention uses a thin plate configuration that derives strength from two-dimensional surface area. The plate's extended surface interacts with sand grains to provide resistance against dislodgement, achieving the necessary strength without the weight penalty of traditional three-dimensional anchor designs.
