Dipterous Insect Attractant Device with Pressure-Balancing Wick Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect attracting devices fail to maintain effective diffusion of attractant compositions under varying temperature and pressure conditions, leading to incomplete or halted diffusion, and lack a mechanism to control the diffusion process.
Innovation Solution
A container system with a cap and cover that balances internal pressure with atmospheric pressure, ensuring continuous and controlled diffusion of the attractant through a wick, using impermeable materials and a tipping mechanism to activate or deactivate diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a wick is used to diffuse attractant composition continuously, then the attractant is released until completely consumed, but the diffusion cannot be deactivated and may be hindered by temperature and pressure changes
Solution Approach 1:
The device incorporates a tipping mechanism that allows it to be switched between an inverted position (diffusion active) and an upright position (diffusion inactive). This dynamic repositioning enables the user to control whether the attractant diffuses or remains contained, resolving the contradiction between continuous diffusion duration and reliability under varying conditions.
Solution Approach 2:
The device utilizes changes in the physical state of the attractant composition through temperature and pressure variations. The container is designed to maintain the attractant in a liquid state under normal conditions, but the system can respond to environmental changes by adjusting the diffusion rate or completely stopping diffusion through the tipping mechanism, thereby maintaining reliability.
2Reliability
If the container is made impermeable to contain the attractant, then the attractant is prevented from leaking, but the diffusion through the wick may be affected by pressure changes inside the receptacle
Solution Approach 1:
The container is designed with different permeability characteristics in different locations: the main body is impermeable to contain the attractant, while the wick provides a controlled pathway for diffusion. This local differentiation of permeability resolves the contradiction between containment and diffusion.
Solution Approach 2:
The wick acts as an intermediary element between the impermeable container and the external environment. It mediates the diffusion process by providing a controlled pathway that is not affected by pressure changes inside the receptacle, ensuring consistent attractant release while maintaining containment.
3Productivity
If the device is designed to diffuse attractant through a wick, then the attractant can be dispersed into the environment, but part of the composition may evaporate without being diffused
Solution Approach 1:
The device maintains continuous diffusion of the attractant composition through the wick by keeping the container in the inverted position. This continuous action prevents evaporation losses by ensuring the attractant is constantly being diffused rather than sitting exposed, thereby resolving the contradiction between diffusion rate and substance loss.
