Modular Transfer Function for Material Emitter Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for emanating materials into the environment, such as insect repellents or perfumes, are limited to a single constant emission mode, failing to accommodate varying application requirements and environmental conditions.
Innovation Solution
A device with a modular electronic circuit that adjusts its operation mode by controlling the power delivered to the emitter using a customizable transfer function, allowing for linear or nonlinear adjustments in emission rate or temperature, and enabling remote updates or changes without altering the entire circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single constant emission mode is used, then the device structure is simple, but the adaptability to different applications is poor
Solution Approach 1:
The patent implements multiple operation modes (first operation mode with first power, second operation mode with second power) that allow the emitter to dynamically adjust its emission characteristics. This enables the device to adapt to different applications such as insect repellent versus perfume emission, different environmental conditions, or user preferences, while maintaining a relatively simple overall structure through mode switching rather than multiple physical components
Solution Approach 2:
The device is designed to perform multiple functions through a single unified structure. The same emitter and housing can operate in different modes (first operation mode and second operation mode) to serve different purposes - whether emitting insect repellent, perfume, or other materials at different rates or temperatures. This multi-functionality approach avoids the need for separate devices for each application
2Adaptability or versatility
If the transfer function is fixed, then the manufacturing process is simple, but the flexibility to update emission characteristics is limited
Solution Approach 1:
The transfer function is pre-determined and stored in the device's control system during manufacturing. This preliminary configuration allows the device to be produced with standard components and processes, while still enabling flexible operation. The pre-stored transfer function can be selected or updated through software/firmware without requiring physical hardware modifications, thus maintaining manufacturing simplicity while providing operational flexibility

Function Achieved in This Case
Enables flexible operation modes tailored to different conditions, such as varying mosquito activity or geographical temperature changes, without requiring hardware modifications, thus enhancing adaptability and reducing production complexity.
Implementation Method 1
The transfer function is configured to gradually and preferably linearly adjust the emission rate of the wick or the temperature of the heater
Implementation Method 2
The PTC increases its resistance with increasing temperature, thus self-regulating when connected to a power source
Implementation Method 3
a wick for transporting the materials from the bottle to the wick

AI summary
A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.
