Solution Overview
Problem
Conventional air cleaners have limited dust collection capability due to their dependence on propeller speed and movement path, and their design often complicates control and maintenance, especially when featuring electrically charged dust collectors that require high voltage and affect propulsion mechanisms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dust collector is structured with intake port and exhaust port having different electric charges, then dust collection capability is improved, but the device size increases and center of gravity becomes unstable
Solution Approach 1:
The exhaust port function is extracted and integrated into the propeller structure itself. The propeller serves dual purposes: propulsion and exhaust, eliminating the need for a separate exhaust port structure. This reduces device size and maintains stable center of gravity while preserving dust collection capability through the charged dust collection electrode.
2Productivity
If high voltage is applied to electrically charge dust particles, then dust collection efficiency is improved, but insulation requirements increase electrode spacing
Solution Approach 1:
The dust collection electrode is nested within the propeller structure, with the charged electrode positioned centrally and the propeller blades surrounding it. This nested arrangement allows high voltage application for efficient dust collection while maintaining compact electrode spacing through proper insulation design, eliminating the need for large spacing between electrodes.
3Use of energy by moving object
If the flying body moves slowly or does not move around easily, then energy consumption is reduced, but dust collection rate decreases
Solution Approach 1:
The dust collection system operates autonomously without requiring flight movement. The charged dust collection electrode actively attracts and collects dust particles from the surrounding air while the drone remains stationary, eliminating the need to trade off between energy consumption and dust collection rate through movement.
