Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect protection methods, such as insect screens and electronic deterrents, are cumbersome, ineffective, or associated with health risks, while existing electric field systems for mosquito deterrence in venetian blinds are prone to malfunctions and safety hazards.
Innovation Solution
A shading device with movably mounted louvers that generate an electric field between adjacent louvers by applying alternating voltage potentials to insulated conductors, ensuring the field deters insects without causing harm, and is designed to be safe and effective in various weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If voltage-carrying conductors are installed in slats to create electric fields for insect protection, then insect repellency is improved, but electrical safety deteriorates due to exposed conductors
Solution Approach 1:
The patent applies insulation coating (a thin film layer) over the voltage-carrying conductors in the slats. This insulation layer acts as a protective barrier that prevents direct contact with users while allowing the electric field to function for insect repellency. The coating transforms the exposed conductor into a safe, enclosed structure that maintains both electrical functionality and safety.
2Adaptability or versatility
If conductors are exposed in slats for electric field generation, then electrical functionality is improved, but manufacturing complexity increases due to insulation requirements
Solution Approach 1:
The patent merges the conductor and insulation into a single integrated component structure. The insulation coating is applied directly to the conductors during manufacturing, creating a pre-assembled insulated conductor unit that is then installed in the slats. This merging approach reduces the number of separate manufacturing steps and simplifies the overall production process.

Function Achieved in This Case
The system effectively deters insects without killing them, is safe from short circuits and electric shocks, and can be retrofitted to existing shading devices, providing effective insect protection with minimal aesthetic impact.
Implementation Method 1
