Solution Overview

Problem

Existing sanitizing doormats face issues with uncontrolled dispensing of sanitizing substances, excessive wetting of soles, quick wear of sponge or porous layers, and complexity in automated systems, making them unsuitable for domestic use.

Innovation Solution

A treadable mat with sanitizing portions featuring a metal support grid, pressurized tanks with dispensing nozzles and electromechanical actuators for controlled sanitizing substance dispensing, and optional vaporization or nebulization means, allowing adjustable and automatic sanitizing treatment without mechanical moving parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a spongy or porous layer is used to dispense sanitising substance, then the substance is released due to user weight, but the amount dispensed is uncontrolled and excessive wetting occurs

Engineering Contradiction:
Improveamount of sanitising substance dispensedVSAvoidcontrol of dispensing amount
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent replaces the passive mechanical absorption system (spongy/porous layer relying on user weight) with an active electromechanical dispensing system. A pump mechanism controlled by a microprocessor reads weight sensor data and activates the pump to dispense a precise, pre-determined amount of sanitising substance, eliminating uncontrolled release and excessive wetting.

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

Solution Approach 2:

The system incorporates weight sensors that detect user weight and feed this information to a microprocessor. The microprocessor then adjusts the pump operation to dispense the appropriate amount of sanitising substance based on the detected weight, creating a closed-loop feedback system that prevents both under-dosing and over-dosing.

Inventive Principle:
Principle #23Feedback

2Reliability

If a spongy or porous layer is used for sanitising, then the layer soaks with sanitising substance, but the layer wears quickly

Engineering Contradiction:
Improvesanitising functionVSAvoidlifespan of porous layer
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent extracts the sanitising substance from the porous layer itself and places it in a separate, replaceable reservoir or tank. The porous layer is replaced with a rigid support structure that does not degrade. This separation allows the sanitising function to be maintained while eliminating the wear problem of the original porous layer.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the physical state and delivery mechanism of the sanitising substance from absorption into a porous matrix to controlled dispensing via a pump system. This parameter change allows precise control over substance release and eliminates the degradation issues inherent in saturated porous materials.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If automated systems with rotating rollers are used for sanitising, then cleaning and sanitising is achieved, but the system becomes complex and suitable only for professional applications

Engineering Contradiction:
Improvecleaning and sanitising effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex rotating roller mechanism from the system. Instead, it uses a simple flat mat surface with an integrated pump-based dispensing system that applies sanitising substance directly to the user's feet or shoes, achieving effective sanitising without the mechanical complexity of rollers.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses weight sensors and a microprocessor to automatically control the dispensing process without user intervention. When a user steps on the mat, the system automatically detects their presence, calculates the appropriate dose based on weight, and dispenses the sanitising substance, eliminating the need for manual operation or complex mechanical cleaning mechanisms.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If pressurised tanks with electromechanical actuators are used, then controlled dispensing is achieved, but the device complexity increases

Engineering Contradiction:
Improveadjustable and controllable dispensingVSAvoidelectromechanical system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into a single unified system: the weight sensors serve both as presence detectors and as dosing calculators; the microprocessor controls both the timing and quantity of dispensing; the pump system handles both substance delivery and dosage control. This multi-functionality reduces the need for separate components and simplifies the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)
