Multi-Functional Dive Spike for River Current Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scuba divers, particularly those in rivers, face challenges with anchoring or stabilizing themselves in strong currents, and existing tools lack versatility for multiple underwater applications.
Innovation Solution
A handheld metal spike with a stainless steel rod and brass handle, secured by a locking pin, designed to serve as a personal anchor, camera stand, light anchor, search line pivot, and animal deterrent, featuring a textured grip, chamfered edges, and attachment points for accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional scuba diving tool is used, then the diver can perform basic diving functions, but the diver cannot effectively anchor or stabilize themselves in strong river currents
Solution Approach 1:
The dive spike is designed as a multi-functional tool that serves as both a personal anchor/stabilizer for river divers and a versatile accessory for various underwater tasks. The single tool integrates anchoring capability with multiple attachment points for cameras, lights, and other diving equipment, eliminating the need for separate specialized tools.
2Reliability
If a lightweight tool is used, then the diver can easily carry it, but the tool lacks sufficient weight to anchor effectively in strong currents
Solution Approach 1:
The spike portion of the tool is designed with adjustable exposure length (8-24 inches) and diameter (1/4 to 1/4 inches) to optimize the weight-to-length ratio. The stainless steel construction provides sufficient weight for anchoring while maintaining a manageable size for carrying. The handle length (5-8 inches) and diameter (% to 11⁄4 inches) are optimized for grip comfort versus structural strength.
3Adaptability or versatility
If a simple spike design is used, then the tool is easy to manufacture, but it lacks the versatility needed for multiple underwater applications
Solution Approach 1:
The dive spike is segmented into distinct functional components: a stainless steel rod/spike for anchoring, a brass handle for gripping, a locking pin for securing the assembly, and threaded holes for accessory attachment. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity and ease of manufacture.
4Reliability
If a heavy-duty anchor is used, then the diver can stabilize in strong currents, but the tool becomes too cumbersome for general diving use
Solution Approach 1:
The dive spike provides dynamic stabilization by allowing the diver to push the spiked end into the river bed and adjust positioning as needed. The tool transitions from a static heavy anchor to a dynamic, manually-positionable stabilizer that adapts to varying current conditions and diver needs, maintaining effectiveness while remaining manageable.

AI summary
The present invention is a multi-functional dive tool designed for use by underwater or scuba divers, in particular divers that do so in rivers. The tool is a handheld metal spike designed to be utilized as a personal anchor or stabilizer when diving in water subject to strong currents. The tool has a pointed end to assist in pushing the spike into the river, ocean or lake bed. Unlike the prior art, the dive spike is constructed of materials with sufficient strength and weight that it can anchor the diver. The tool may also be used for a stand for cameras or lights, an anchor or pivot point for search lines, or an animal deterrent among other uses.
