Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deterrent devices for marine-dwelling animals, such as seals, often cause harm, require complex installation, consume energy, and create environmental hazards, while also occupying valuable space and being difficult to store and maintain.
Innovation Solution
A modular, easy-to-install deterrent device with rotating elements that irritate animals without causing harm, designed to be stackable and energy-efficient, allowing for minimal space usage and easy removal, using temporary attachment methods to avoid damage to structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art deterrent devices such as pyrotechnics, slingshots, electric fencing, or acoustic devices are used, then marine animals are deterred from occupying structures, but these devices can harm animals, require complex installation, consume energy, create environmental hazards, occupy valuable space, and be difficult to store and maintain
Solution Approach 1:
The patent employs inexpensive, simple objects like plastic bottles, pool noodles, foam pieces, or painted rocks as deterrents. These objects are deliberately designed to be temporary and easily replaceable rather than permanent fixtures. They provide deterrence through their presence and appearance without causing harm to animals or requiring complex installation infrastructure.
Solution Approach 2:
The patent extracts the essential deterrent function from complex systems and isolates it into simple, standalone objects. Rather than using integrated systems with power supplies, control circuits, and mounting structures, the invention uses individual discrete objects that can be independently deployed and removed without affecting other components.
2Reliability
If prior art deterrent devices are installed on marine structures, then animals are deterred, but installation is complex and may cause damage to the structure
Solution Approach 1:
The deterrent system is divided into numerous small, independent objects rather than a single integrated installation. Each object (bottle, foam piece, painted rock) is a separate unit that can be individually placed on the structure. This segmentation allows flexible deployment without requiring complex mounting procedures or structural modifications.
Solution Approach 2:
Objects are prepared in advance for deployment by simply placing them on the structure during low tide or when the area is accessible. Some objects like bottles may be pre-filled with water or weighted, but the installation itself requires no complex assembly on-site. The deterrents are ready-to-use objects that need only be positioned, not assembled or activated.
3Reliability
If traditional deterrent devices are deployed, then animal deterrence is achieved, but valuable space on the structure is occupied and normal use is precluded
Solution Approach 1:
Instead of covering the entire structure with continuous deterrent barriers, the patent uses scattered, discrete objects placed at strategic locations. This partial action approach provides sufficient deterrence through the presence of multiple small deterrent points without blocking movement or occupying large continuous areas. Animals are deterred by encountering these objects rather than by complete coverage.
Solution Approach 2:
The deterrent effect is concentrated at specific local points where individual objects are placed rather than distributed uniformly across the entire structure. Each object creates a localized deterrent zone, allowing areas between objects to remain fully accessible for normal human use. The structure maintains its full functionality while providing targeted deterrence at key locations.
4Reliability
If prior art deterrent devices are used, then animals are deterred, but the devices require energy to operate and consume resources
Solution Approach 1:
The deterrent objects are completely passive and self-sufficient, requiring no external energy input or resource consumption. Plastic bottles, foam pieces, and painted rocks derive their deterrent effect purely from their physical presence, appearance, and placement on the structure. They maintain their deterrent function indefinitely without batteries, power sources, or consumable materials.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively discourages marine animals from occupying structures while minimizing environmental impact and energy consumption, allowing for easy installation, removal, and storage without precluding normal use of the area.
Implementation Method 1
a rotating element rotatably attached to the other end of the stand-off block member

AI summary
Apparatus and methods are disclosed for deterring marine animals such as seals and other marine-dwelling animals from mounting or hauling out onto a marine vessel or structure. In one embodiment, the device comprises a base support member for attachment of the device to a structure to be protected. The base support member includes a stand-off block member and associated irritating, non-fixed/rotating element attached thereto. When large animals such as seals mount on a structure where the deterrent device is installed, the preferably blunted corners of the rotating element cause discomfort to the animal by creating pressure points on the skin or blubber of the animal as they brush by or step on the device. The non-fixed/rotating element preferably can turn or otherwise release the animal as it moves away from the discomfort. Thus, the invention preferably irritates these nuisance animals sufficiently to make them move from that area, while minimizing or eliminating the risk of harm to the animal. Methods are disclosed for deterring animals from getting into and/or staying in selected/protected areas, as well as other methods such as ways of attaching the device to surface to be protected in order to deter animals from getting onto that surface.
