Perimeter Repellent Dispenser Using Blowers for Wide-Area Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pest control systems for mosquitoes and insects are limited to small, localized areas, inefficient, and dissipate repellent chemicals due to heat, lacking an automated system for continuous and effective coverage.
Innovation Solution
A mosquito and insect repellant dispenser using a blower or compressor to disperse repellents through tubing and vented tubes, powered by batteries or AC, with a central controller for automated operation and remote control options, capable of covering larger areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional localized pest control methods are used, then the device complexity is low, but the area of coverage is limited to small localized areas
Solution Approach 1:
The system is divided into multiple independent components: a central controller unit, multiple blowers distributed throughout the area, and a network of tubing with vents. Each blower operates independently to cover specific zones, allowing the system to scale coverage area by adding more segments rather than expanding a single unit.
Solution Approach 2:
A central controller acts as an intermediary that coordinates multiple blowers and manages the dispensing schedule. The controller receives inputs (timer, motion detection, remote commands) and distributes control signals to appropriate blowers, enabling automated operation across large areas without requiring complex direct control wiring to each device.
2Productivity
If manual pest control operation is used, then the device complexity is low, but the productivity is reduced due to considerable labor requirements
Solution Approach 1:
The system incorporates automatic operation through a central controller that manages blowers based on predetermined schedules, timer inputs, or motion detection triggers. The motion-activated mode automatically activates blowers when movement is detected, eliminating the need for manual monitoring and operation while maintaining effective pest control.
Solution Approach 2:
The system operates in periodic cycles through timer-based control, where blowers are activated for specific durations at scheduled intervals. This periodic operation pattern maintains effective repellent distribution while reducing energy consumption and allowing automated adjustment of operational frequency and duration.
3Loss of time
If repellent chemicals are dispensed without automation, then the device complexity is low, but the loss of time occurs due to manual intervention requirements
Solution Approach 1:
The system is pre-configured with programmed schedules and operational parameters stored in the central controller. Blow ers are pre-positioned throughout the area with tubing connected, and the controller is pre-programmed with timing sequences. When activated, the system immediately executes the predetermined dispensing schedule without requiring manual setup or intervention for each operation cycle.
4Loss of substance
If heat-based repellent dispersion is used, then the device complexity is low, but the loss of substance occurs due to significant dissipation of repellent chemicals
Solution Approach 1:
The system uses pneumatic pressure from electric blowers to force repellent chemicals through tubing and out through vents as a controlled mist or vapor. This pneumatic delivery method provides precise control over dispensing rate and distribution pattern, ensuring repellent is released gradually and evenly across the coverage area rather than dissipating rapidly through uncontrolled heat-based evaporation.

AI summary
The present disclosure relates to a repellent dispenser for bugs and mosquitoes. The dispenser contains a body housing one or more repellent reservoirs, and a blower or compressor connected to the one or more repellent reservoirs. The blower or compressor is further connected to one or more dispensing horns or tubes. A dispensing horn or an end cap exhaust may also be connected to the end of a tube. The repellent reservoirs may include sensors that are able to detect a liquid level in each of the one or more repellent reservoirs and send a signal when the liquid level is below a threshold. The blower or compressor can be set to operate for a preset duration, at specific intervals, at a designated time, or at a designated power level. The dispenser may also have a tab that enables the dispenser to be mounted on a parapet or handrail.
