Solution Overview
Problem
Conventional nebulizers for disease prevention and disinfection have limitations in uniformly spraying chemical solutions over large areas and tend to leave residues on surfaces due to larger particle sizes, and they require frequent recharging, disrupting continuous operation.
Innovation Solution
A portable sterilizer with a conical nozzle, blower, and detachable battery, featuring a chemical feed pipe and mist nozzles that produce ultra-fine particles for extended air presence and efficient disinfection, along with a chemical recovery system to prevent residue and allow continuous operation by battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional sprayers use larger particles (30 μm to 50 μm) for spraying, then the chemical solution can be distributed over a large area, but the particles leave traces on furniture and electronic products after falling
Solution Approach 1:
The patent changes the particle size parameter from conventional 30-50 μm to ultra-fine particles of 1-30 μm through a specialized nozzle structure. This parameter change allows the particles to remain suspended in air longer and settle more evenly, reducing residue on surfaces while maintaining wide coverage area
Solution Approach 2:
The patent introduces an additional dimension by using a conical nozzle with specific angle geometry to control particle trajectory and distribution. The conical shape at 15-45 degrees creates a three-dimensional spray pattern that enhances coverage while minimizing direct contact with surfaces
2Manufacturing precision
If conventional nebulizers pulverize chemical solution to spray uniformly over large area, then disease prevention effects are improved, but they cannot spray far away
Solution Approach 1:
The patent changes the particle size parameter to ultra-fine 1-30 μm range, which extends the floating time and travel distance of particles in air. This allows uniform distribution over both large areas and long distances simultaneously
Solution Approach 2:
The patent segments the spray function into two components: a conical nozzle for pulverization and uniform distribution, and a blower for providing airflow to extend spray distance. This segmentation allows each component to optimize its function independently
3Adaptability or versatility
If conventional sprayers use built-in batteries, then the device is self-contained, but working time is limited and recharging causes inconvenience and increases total working time
Solution Approach 1:
The patent extracts the battery from the main housing and provides it as a separate, removable component. This allows the battery to be easily replaced when depleted, eliminating recharging wait time and enabling continuous operation while maintaining portability
Solution Approach 2:
The patent implements a battery replacement system where depleted batteries are discarded and fresh batteries are inserted. This approach allows continuous operation without recharging, as used batteries can be recovered and recharged separately
