Solution Overview

Problem

Existing de-icing and snow removal solutions are inefficient as they only activate after ice or snow has formed and are not correlated with real-time weather warnings, leading to suboptimal road surface maintenance during severe weather events.

Innovation Solution

An automated road surface maintenance installation that uses real-time meteorological data from weather stations to prevent ice and snow formation by distributing de-icing fluids and compressed air through a network of underground nozzles, controlled remotely via a GSM module, allowing for proactive maintenance before severe weather conditions occur.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If de-icing installations are activated only after ice or snow has formed, then the system responds to actual conditions, but road surface maintenance becomes reactive rather than preventive, leading to suboptimal maintenance during severe weather events

Engineering Contradiction:
Improveroad surface maintenance effectivenessVSAvoidresponse time to weather events
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system activates de-icing installations before ice or snow formation by receiving weather warnings from an infra weather system. The control unit triggers the spraying subsystem in advance based on predicted weather conditions, transforming the system from reactive to preventive maintenance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates sensors that continuously monitor road surface temperature, atmospheric temperature, humidity, and precipitation. This real-time feedback allows the control unit to adjust operations dynamically, ensuring maintenance actions are taken at the optimal moment based on actual environmental conditions.

Inventive Principle:
Principle #23Feedback

2Device complexity

If de-icing installations are mounted on the side of the road or on bridge rails, then the installation structure is simple, but the system cannot provide comprehensive coverage and real-time correlation with weather warnings in the respective microclimate

Engineering Contradiction:
Improveinstallation structureVSAvoidroad surface coverage area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The system divides the road into multiple segments, each equipped with its own weather station and control unit. This segmentation allows each section to be independently monitored and treated, providing comprehensive coverage while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an infra weather system as an intermediary that provides real-time weather warnings and microclimate data. This intermediary layer enables the control units to receive accurate local weather information and trigger appropriate maintenance actions without requiring complex direct sensing infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If manual application of solid anti-skid mixtures is used, then the system is simple to implement, but it requires human intervention and cannot provide continuous or preventive maintenance

Engineering Contradiction:
Improvesystem implementation simplicityVSAvoidmaintenance operation automation
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The system is designed to operate autonomously by receiving weather warnings from the infra weather system and automatically triggering the spraying subsystem through the control unit. The sensors continuously monitor conditions and adjust operations without human intervention, enabling continuous preventive maintenance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical application of anti-skid mixtures with an automated spraying subsystem that delivers liquid de-icing agents through pumps and nozzles. This substitution maintains implementation simplicity while achieving full automation and continuous operation capability.

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

4Reliability

If existing installations wait for sensor detection of ice or snow formations, then the system operates based on actual conditions, but it is inefficient during traffic and cannot prevent phenomena formation

Engineering Contradiction:
Improveroad surface conditionVSAvoidmaintenance efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By receiving weather warnings in advance from the infra weather system, the control unit activates the spraying subsystem before ice or snow forms. This preliminary action prevents phenomena formation rather than responding to them, improving both road surface condition and maintenance efficiency during traffic conditions.

Inventive Principle:
Principle #10Preliminary action
