Portable Dual-Tank Insect Control Device with Programmable Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices for insect control can only nebulize either biocide or repellent substances, requiring multiple devices or laborious changes, leading to frequent treatments with potential side effects on plants and children's safety, and limited coverage in partially open areas.
Innovation Solution
A portable device with two separate tanks for biocide and repellent substances, a programmable control unit, and a photovoltaic panel for extended operation, allowing simultaneous spraying of both substances and adjustable nozzles for comprehensive area coverage without frequent device repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single tank containing only biocide or only repellent is used, then the device structure is simple, but multiple devices or frequent tank changes are required to achieve comprehensive insect control
Solution Approach 1:
The patent combines two separate tanks (one for biocide, one for repellent) into a single integrated device structure. The tanks are positioned side-by-side within the device housing, with each tank connected to its own spray nozzle assembly. This merging approach allows the device to perform both biocide and repellent functions simultaneously without requiring multiple separate devices or frequent tank changes, while maintaining relatively simple internal architecture.
Solution Approach 2:
The device is designed with multi-functionality by incorporating both biocide and repellent tanks within a single unit. The control unit can independently operate either tank or both simultaneously based on programming, making the device universally applicable for different insect control needs and scenarios without requiring separate specialized devices.
2Reliability
If biocide is sprayed frequently to maintain effectiveness, then insect control is improved, but side effects on plants and children's safety increase
Solution Approach 1:
The repellent substance acts as an intermediary that prevents insects from approaching the area in the first place, eliminating the need for frequent biocide applications. The repellent creates a protective barrier that insects avoid, while the biocide remains as a backup for insects that manage to penetrate the repellent zone. This intermediary approach reduces biocide frequency and associated harmful effects.
Solution Approach 2:
The device implements periodic spraying cycles where repellent is applied continuously or at frequent intervals to maintain the protective barrier, while biocide is applied less frequently only when needed. The control unit programs different spray intervals for the two substances, optimizing effectiveness while minimizing harmful exposure from biocide applications.
3Device complexity
If spray nozzles have fixed orientation, then the device structure is simple, but area coverage is limited and requires frequent repositioning
Solution Approach 1:
The spray nozzles are designed with adjustable orientation capabilities, allowing them to be dynamically repositioned to different angles and directions. The nozzle assemblies can be manually or automatically adjusted to target specific areas or follow insect movement patterns. This dynamic adjustment capability expands the effective coverage area without requiring the entire device to be repositioned frequently.
4Duration of action of moving object
If the device operates for extended periods without charging, then operational autonomy is improved, but energy consumption increases and requires larger battery capacity
Solution Approach 1:
The device employs periodic operation cycles where the pumps and spray systems are activated in intervals rather than continuously. The control unit programs spray cycles that alternate between active spraying and idle periods, reducing overall energy consumption while maintaining effective insect control through the residual effects of previously applied substances. This periodic action extends operational autonomy on existing battery capacity.
