Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing animal repellent devices are cumbersome, unsightly, and unsafe for use on boat decks, and lack a compact, portable, and integrable system to effectively deter birds without a land-based water source.

Innovation Solution

A motion-activated spray device with a nozzle, water pump, and power source, integrated into or mounted on a boat, capable of adjusting spray direction and force, using a water reservoir as the water source, and equipped with a mounting system for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a motion-activated spray device is used to repel birds from boat decks, then bird deterrence effectiveness is improved, but device portability and stowability deteriorate due to the need for mounting systems and integration components

Engineering Contradiction:

Improvebird deterrence effectivenessVSAvoiddevice portability and stowability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into separate functional modules: a motion detector unit, a spray mechanism unit, and a mounting unit. This segmentation allows the core spray function to be compact and portable while the mounting system can be adapted to different boat configurations without requiring the entire device to be permanently installed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting system is designed with universal adaptability to accommodate different boat deck surfaces and configurations. The device can be mounted using various methods (screws, adhesives, clamps) and can be easily installed or removed, providing both secure mounting for effectiveness and portability when needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a compact spray device is used without land-based water sources, then device portability is improved, but water supply reliability deteriorates

Engineering Contradiction:

Improvedevice portabilityVSAvoidwater supply reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A water reservoir serves as an intermediary between the device and natural water sources. The reservoir stores a sufficient supply of water onboard the boat, decoupling the device from land-based water infrastructure while maintaining reliable water supply for the spray function.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device is designed to be self-sufficient with an integrated water reservoir that can be filled and stored onboard. The system includes its own water storage and delivery mechanism, eliminating dependence on external land-based water sources while maintaining operational reliability.

Inventive Principle:

Principle #25Self-service

3Reliability

If existing animal repellent devices are used on boat decks, then bird deterrence is achieved, but device safety and aesthetic appearance deteriorate due to cumbersome and unsightly designs

Engineering Contradiction:

Improvebird deterrenceVSAvoiddevice safety and aesthetic appearance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The spray nozzle is designed with adjustable and movable characteristics, allowing the spray direction and coverage area to be optimized for bird deterrence while positioning the main device body in less obtrusive locations on the boat deck, reducing both safety hazards and aesthetic impact.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device housing and mounting components utilize sleek, modern designs with smooth surfaces and compact profiles that blend better with boat aesthetics. The spray mechanism is enclosed in a protective yet aesthetically pleasing housing that reduces visual clutter and potential safety hazards compared to traditional exposed mechanical designs.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A system for repelling animals that includes a spraying device, a water pump, a motion detector, and a power source. The system will cause the spraying device to spray water when the motion detector detects motion. The inclusion of the water pump allows the system to be used on boats that are at sea or in other situations where a pressurized water source is not readily available. The system may include means for changing a direction of the spray of the water, including the directions of both vertical and lateral motion. As such, a specific area to be sprayed may be programmed into the system so that the system will only spray in that area.
