Flashlight with Thermally Conductive Heating Plate for Volatile Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mosquito repellent devices lack versatility, as they either do not provide adequate lighting or require an open flame for both illumination and substance dispersion, and users cannot control the light source independently from the repellent dispensing.
Innovation Solution
A handheld flashlight with a thermally conductive heating plate for dispensing volatile substances, powered by a portable battery, allowing independent control of light and repellent dispensing, with adjustable LED light intensity and no open flame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a candle or flame is used to heat the mat for volatilizing insect repellent, then the device provides both light and heat, but the light intensity cannot be controlled and the flame is not very luminous
Solution Approach 1:
The device is divided into two independent systems: a flame-based heating system for volatilizing insect repellent and a separate LED-based lighting system. This segmentation allows each system to be controlled independently, resolving the contradiction between providing light and controlling light intensity separately from repellent dispensing.
Solution Approach 2:
The device combines multiple functions into a single unit: insect repellent dispensing through flame heating and adjustable LED lighting. This multi-functionality allows the device to provide both light and heat while maintaining independent control over each function, enhancing versatility.
2Use of energy by moving object
If the light source is turned off to save energy, then energy consumption is reduced, but the insect repellent dispersal also stops
Solution Approach 1:
The device separates the lighting function from the repellent dispensing function, allowing users to control each independently. Users can turn off the LED light to save energy while maintaining flame-based repellent dispersal, or use the LED light without the flame, providing flexible energy management.
3Device complexity
If an open flame is used for heating, then the device is simple in structure, but it requires matches or lighters to operate and poses safety risks
Solution Approach 1:
The device incorporates a piezoelectric ignition system that generates sparks automatically when a button is pressed, eliminating the need for external matches or lighters. This self-service ignition mechanism maintains structural simplicity while significantly improving ease of operation and safety.
4Illumination intensity
If a focused flashlight light is used for illumination, then lighting needs are better met, but existing devices do not provide adequate lighting with their flame-based systems
Solution Approach 1:
The device combines a flame-based heating system for repellent dispensing with a separate LED flashlight system for illumination. This multi-functionality provides both focused flashlight light for better visibility and the traditional flame-based repellent system, giving users multiple lighting and repellent options.
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
Provides a versatile, portable, and effective mosquito repellent system with adjustable lighting, allowing users to control both light and repellent dispensing independently, suitable for various outdoor situations.
Implementation Method 1
a butane cartridge supplies fuel to uniformly heat a thermally conductive plate upon which a mat containing volatile insect repellent is positioned. When the plate is sufficiently heated, the insect repellent is volatilized and thereby dispensed.
Implementation Method 2
a butane cartridge supplies fuel to uniformly heat a thermally conductive plate
Implementation Method 3
a piezoelectric device is provided which, when actuated, generates an electrical spark across a spark gap
Implementation Method 4
a device that combines a flashlight and a dispensing system that uses fossil or hydrocarbon fuels to heat volatile substances
Data Source
AI summary
A combination flashlight and insect repellent dispensing apparatus. Light is produced by light bulbs or LEDs whereas insect repellent is dispensed by heating a volatilizable insecticide. The insecticide and portable light may be used either concurrently or independently of each other.
