Water-Filled Bladder Anchor for Rocky Shoreline Mooring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems that drive stakes into rocky shorelines to secure boats are damaging and illegal, and heavy anchors are ineffective in certain water bodies with steep canyon walls and rocky structures.
Innovation Solution
A bladder anchor system comprising an outer bladder and an inner bladder, filled with water to weigh down a bridle on the shoreline, securing the boat without damaging the shoreline, using a bridle harness, outer and inner bladder reinforcement connectors, and a water inlet system to fill and drain the bladders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stakes are driven or drilled into rocky shorelines to secure boats, then anchoring effectiveness is improved, but shoreline damage occurs and environmental regulations are violated
Solution Approach 1:
The patent introduces a bladder as an intermediary device between the boat and the shoreline. The bladder is filled with water to create weight and friction, allowing the boat to be secured without direct penetration of the shoreline. This mediator approach resolves the contradiction by providing anchoring effectiveness through water weight while avoiding shoreline damage entirely.
Solution Approach 2:
The patent utilizes hydraulics by filling the bladder with water from the body of water itself. The water-filled bladder creates sufficient weight and friction against the shoreline surface to secure the boat effectively, while the liquid nature of water allows the system to adapt to various shoreline surfaces without causing mechanical damage through drilling or driving stakes.
2Reliability
If heavy anchors with mass are used to secure boats, then anchoring holding power is improved, but the anchor cannot rest on the bottom in steep canyon walls and rocky structures
Solution Approach 1:
The patent changes the parameter of anchoring from relying on fixed mass (heavy anchors) to relying on adjustable water weight. The bladder can be filled with varying amounts of water depending on the specific conditions of the water body and shoreline, allowing the same device to adapt to different environments including steep canyon walls and rocky structures where traditional heavy anchors would fail.
Solution Approach 2:
The bladder anchor system serves multiple functions: it can be used on various shoreline types (rocky, sandy, steep), in different water bodies (lakes, reservoirs, rivers), and can be deployed from different positions. This universal applicability resolves the contradiction by making the anchoring system versatile across different environments while maintaining effective holding power through water weight.

AI summary
An anchor system with a bridle substrate and harness configured to attach to an anchor line. An outer bladder surrounds an inner bladder for coupling on top of the bridle substrate. Water enters the anchor system through a water inlet that feeds directly to the inner bladder and fills that first. Water then overflows from the inner bladder to the outer bladder to fill that second. The inner bladder provides stability and is positioned with a majority of its volume closer to an uphill end of the anchor bladder while the outer bladder is positioned with a majority of its volume closer to a downhill end of the anchor bladder. Reinforcement connectors for each bladder resist deformation of the bladders to resist movement of the anchor bladder while filling.
