Collapsible UV Insect Extermination Device with Protective Shroud
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV lighting devices for insect extermination are unsightly and unsanitary when transported near food, and the light can be too bright for indoor use, lacking versatility.
Innovation Solution
A collapsible flashlight/insect extermination device with an extendable design that houses the UV light and electrical grid within a protective shroud, allowing for both open and closed configurations, featuring a dual LED light source with pulse-width modulation for adjustable brightness and a power bank for external device charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UV light and extermination grid are always exposed, then insect extermination function is available, but the device becomes unsightly and unsanitary when transported near food
Solution Approach 1:
The patent implements a dynamic configuration system where the protective shroud can be extended to cover or retracted to expose the UV light and electrical grid. This allows the device to adapt between two states: a closed configuration for sanitary transport and an open configuration for active insect extermination, resolving the contradiction between always being functional and being suitable for food-adjacent environments.
2Reliability
If the UV light is always exposed, then insect attraction is maximized, but the light becomes too bright for indoor use
Solution Approach 1:
The protective shroud serves as a dynamic control mechanism that regulates light exposure. When extended, it blocks or diffuses the UV light, reducing brightness to indoor-appropriate levels while still allowing the device to function. When retracted, it maximizes light exposure for optimal insect attraction, thus resolving the contradiction between constant functionality and indoor suitability.
3Volume of moving object
If the device is designed for compact storage, then portability is improved, but the extendable mechanism increases device complexity
Solution Approach 1:
The protective shroud is designed to nest within or alongside the main device body when in the closed configuration. This nesting approach allows the extendable mechanism to provide both compact storage and functional extension without proportionally increasing overall device complexity, as the shroud integrates with existing structural elements rather than adding completely separate components.
Data Source
AI summary
A handheld lighting apparatus is disclosed having a top housing coupled to a first light source and an electrical grid configured to distribute a quantity of electricity to an object that contacts adjacent portions of the grid. The top housing is slidably mounted to a bottom housing having a cavity therein, the cavity being configured to receive the electrical grid assembly therein. The first light source emits light ranging from about 400 nm to about 720 nm in a first mode and light ranging from about 315 nm to about 400 nm in a second mode. A second light source is disposed about the bottom housing configured to propagate light in a direction that is parallel to a longitudinal direction of the lighting apparatus.
