Solution Overview

Problem

Existing public transportation vehicles, such as buses, face challenges in effectively preventing the spread of diseases due to limitations in current epidemic prevention methods, as the door design interferes with the application of general disinfection tunnels and passenger disinfection is not comprehensive.

Innovation Solution

A vehicle door epidemic prevention device is installed on public transportation vehicles, featuring a movable disinfection unit with spray nozzles and ultraviolet lamps on the door panel that activates when the door opens, ensuring disinfection of passengers without interference from the door's actuating mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed disinfection device is installed in the doorway, then disinfection function is provided, but the door actuating mechanism interferes with the disinfection unit's operation and positioning

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidinterference with door mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The disinfection unit is made movable and is disposed on the door panel to be moved along with the door panel. When the door panel is in the open position, the disinfection unit faces the doorway to perform disinfection. This dynamic positioning resolves the contradiction by allowing the disinfection unit to automatically adjust its position relative to the door mechanism, avoiding interference while maintaining disinfection effectiveness.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If passengers wear masks for epidemic prevention, then some protection is provided, but the epidemic prevention effect is limited

Engineering Contradiction:
Improveepidemic prevention effectVSAvoiddisinfection system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs a disinfection unit that can include a spray nozzle for spraying disinfectant and/or an ultraviolet lamp for UV irradiation. These strong disinfection methods go beyond simple mask-wearing by using chemical oxidants and UV radiation to effectively kill pathogens, providing enhanced epidemic prevention效果 while accepting the added complexity of the disinfection system.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

3Reliability

If general disinfection tunnels are applied to buses, then comprehensive disinfection is achieved, but the door design with opening/closing mechanisms makes direct application impossible

Engineering Contradiction:
Improvedisinfection coverageVSAvoidcompatibility with door design
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

Instead of applying a complete disinfection tunnel system to the bus, the invention segments the disinfection function into a compact unit that can be integrated into the door panel. This segmented approach allows the disinfection capability to be adapted to the specific door design while maintaining effective disinfection coverage for passengers entering or exiting the bus.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device effectively disinfects passengers as they enter or exit the vehicle, enhancing epidemic prevention by using a combination of disinfectants and UV light, even in the presence of the door's mechanical components, thereby improving public health safety.

Implementation Method 1

The disinfection unit can choose a spray nozzle with the function of spraying disinfectant

Methodology Applied
Scientific EffectSpray: Spray

Implementation Method 2

or an ultraviolet lamp, or both the spray nozzle and the ultraviolet lamp

Methodology Applied
Scientific EffectUltraviolet radiation: Light
