Solution Overview
Problem
Conventional insect catching devices with radiation sources are often bulky, increasing the risk of collisions and material costs, and can contaminate environments due to debris from decomposed insects, while the proximity of radiation sources to adhesive materials can impair their performance by generating heat.
Innovation Solution
A slimmer insect catching device design with a housing that includes a radiation source and an adhesive catching member, featuring a vent for airflow to dissipate heat and a shield to reduce direct radiation exposure, allowing for efficient insect capture while minimizing adhesive material degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the radiation source is placed closer to the adhesive material to reduce device depth, then the device becomes slimmer and more space-efficient, but the adhesive material absorbs more heat which impairs its performance and working lifetime
Solution Approach 1:
The housing is divided into front and rear portions with a specific aperture configuration that segments the light path and allows the radiation source to be positioned closer to the adhesive material while maintaining performance through controlled radiation exposure
Solution Approach 2:
A reflective surface is introduced as an intermediary between the radiation source and the adhesive material. This reflective surface directs radiation toward the aperture while shielding the adhesive material from direct heat exposure, enabling closer positioning without performance degradation
2Length of stationary object
If the device depth is reduced to minimize collision risk and material costs, then the device becomes more compact and safer, but the ability to accommodate components and manage heat is compromised
Solution Approach 1:
The housing utilizes a three-dimensional configuration with front and rear portions connected at angles, creating volumetric efficiency. This dimensional arrangement allows adequate component spacing and heat management within a reduced depth footprint
Solution Approach 2:
The reflective surface acts as a heat management intermediary, directing radiation away from the adhesive material while maintaining the compact housing design, thus controlling heat generation in the reduced-depth configuration
3Productivity
If the radiation source emits more intense radiation to improve insect attraction, then the device becomes more effective at capturing insects, but the heat generated impairs the adhesive material faster
Solution Approach 1:
The housing structure provides localized protection to the adhesive material through its geometric configuration and positioning, allowing the radiation source to emit intense radiation for high productivity while the local housing structure shields the adhesive from excessive heat
Solution Approach 2:
The reflective surface serves as a mediator that separates the radiation function from the heat transfer function, allowing intense radiation emission for improved insect attraction while preventing corresponding heat transfer to the adhesive material
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
The device effectively captures insects with reduced bulk, minimizing debris contamination and extending the adhesive material's lifespan by managing heat and radiation exposure, thus maintaining efficiency and reducing material costs.
Implementation Method 1
the housing defines a vent located in a bottom side of the housing and separately from the aperture to create an airflow to draw cool air from below the housing into the housing by convection resulting from the heat generated by the radiation source during use of the device
