Solution Overview

Problem

Customer service devices with touch man-machine interfaces face hygiene and security issues due to shared use without sanitization and potential for cloning or abuse, necessitating a secure and healthy access method.

Innovation Solution

A method allowing users to remotely access services via a mirroring application on their terminal, verifying authorized service providers and establishing a pairing without direct contact, using QR codes or Bluetooth/WiFi connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If customers use the touch man-machine interface directly, then service accessibility is improved, but hygiene safety deteriorates due to lack of sanitization

Engineering Contradiction:
Improveservice accessibilityVSAvoidhygiene safety
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent creates a virtual copy of the touch man-machine interface on the customer's terminal device. The interface is mirrored and replicated remotely, allowing customers to interact with services through their own devices rather than physically touching the public interface. This copying approach maintains service accessibility while eliminating direct contact with potentially contaminated surfaces.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a communication network as an intermediary between the customer and the customer service device. The network enables remote interaction through data transmission, allowing the customer's terminal to communicate with the service device without physical contact. This intermediary layer preserves ease of operation while ensuring hygiene safety by eliminating direct touch.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If customers use the touch man-machine interface directly, then service accessibility is improved, but security deteriorates due to potential cloning or abuse

Engineering Contradiction:
Improveservice accessibilityVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a virtual replica of the interface on the customer's terminal, allowing service access without physical interaction. This copying mechanism maintains accessibility while improving security by eliminating the physical interface that could be cloned or tampered with. The virtual interface is bound to authenticated customer devices, preventing unauthorized access.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The communication network serves as a secure intermediary that authenticates and manages connections between customer terminals and the service device. This intermediary layer implements security protocols, verifies device identities, and controls access permissions, thereby maintaining service accessibility while preventing cloning and abuse through technical security measures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If hand gel dispensers are installed for sanitization, then hygiene safety is improved, but device complexity and maintenance requirements worsen

Engineering Contradiction:
Improvehygiene safetyVSAvoidmaintenance requirements
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts the sanitization function from the physical environment by enabling remote access through terminal devices. Instead of adding hand gel dispensers to the customer service device, the solution removes the need for physical contact entirely. Customers can access services remotely without needing on-site sanitization equipment, thereby improving hygiene safety while reducing device complexity and maintenance burden.

Inventive Principle:
Principle #2Taking out (Extraction)
