Solution Overview

Problem

Public transport vehicle support columns are frequently contaminated with germs, leading to hygiene concerns, and existing cleaning methods are time-consuming, costly, and pose risks to staff and the environment.

Innovation Solution

A sanitizing system using a UV-C electromagnetic radiation source that automatically slides along the columns, powered by a magnetic operating system, allowing for rapid and chemical-free disinfection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical cleaning products are used on support columns, then hygiene level is improved, but staff safety and environmental friendliness deteriorate

Engineering Contradiction:
Improvehygiene levelVSAvoidstaff safety and environmental impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical cleaning methods with a UV-C radiation system. The electromagnetic radiation source emits UV-C light that sterilizes the support column surface without requiring chemical products, thereby maintaining hygiene improvement while eliminating harmful effects on staff and the environment

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the cleaning mechanism from chemical to physical (electromagnetic radiation). By using UV-C radiation with specific wavelength parameters, the system achieves sterilization through physical means rather than chemical reactions, resolving the contradiction between effectiveness and safety

Inventive Principle:
Principle #35Parameter changes

2Reliability

If manual cleaning of columns is performed, then hygiene is improved, but time consumption and operational downtime increase

Engineering Contradiction:
Improvehygiene levelVSAvoidcleaning time and vehicle downtime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables automated cleaning of support columns without requiring manual intervention. The electromagnetic radiation source is automatically deployed and retracted, performing sanitization independently and significantly reducing the time and labor required compared to manual cleaning methods

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical cleaning with an automated UV-C radiation system. The electromagnetic source is mounted on a deployable structure that automatically positions itself along the column, eliminating the need for staff to manually clean each column and thereby reducing operational downtime

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If frequent cleaning of columns is performed, then hygiene level is improved, but operational costs and service disruption increase

Engineering Contradiction:
Improvehygiene levelVSAvoidoperational efficiency and cost-effectiveness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The automated system allows frequent sanitization cycles without proportionally increasing operational costs. Once installed, the system operates independently with minimal staff intervention, enabling multiple cleaning cycles per day without the recurring labor costs associated with manual cleaning

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

By replacing manual cleaning with an automated UV-C system, the patent eliminates the direct correlation between cleaning frequency and labor costs. The system can be operated frequently with only electrical power consumption as a recurring cost, significantly improving cost-effectiveness compared to manual methods

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
