Solution Overview

Problem

Retailers are reluctant to accept cryptocurrencies due to price fluctuations, and consumers bear the risks of valuation changes, while existing cryptocurrency terminals are expensive and occupy valuable retail space.

Innovation Solution

Integrate a digital currency transaction manager into existing POS terminals to facilitate cryptocurrency transactions, allowing interaction with cryptocurrency exchanges and providing an interface for both cryptocurrency and government-backed currency transactions, reducing the need for specialized terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If specialized cryptocurrency terminals are deployed, then cryptocurrency transaction capability is provided, but retail space is occupied and high cost is incurred

Engineering Contradiction:

Improvecryptocurrency transaction capabilityVSAvoidretail space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent integrates cryptocurrency transaction functionality into existing multi-functional POS terminals. The terminal can process both traditional payments (credit cards, cash) and cryptocurrency transactions through a unified interface, eliminating the need for separate dedicated cryptocurrency terminals and thereby conserving valuable retail space.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines cryptocurrency exchange functionality with the existing POS terminal system. By merging these functions into a single integrated platform, the system provides both traditional and cryptocurrency payment processing without requiring separate physical terminals, thus reducing space occupation.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If specialized cryptocurrency terminals are deployed, then cryptocurrency transaction capability is provided, but high acquisition and maintenance cost is incurred

Engineering Contradiction:

Improvecryptocurrency transaction capabilityVSAvoidterminal acquisition and maintenance cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent enables existing POS terminals to perform both traditional and cryptocurrency transactions through software integration. This multi-functionality eliminates the need for expensive dedicated cryptocurrency terminals, reducing both acquisition costs and ongoing maintenance expenses while preserving cryptocurrency transaction capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements cryptocurrency transaction functionality through software modules that replicate exchange capabilities within the existing POS terminal environment. This virtual implementation avoids the need for expensive physical specialized hardware, thereby reducing manufacturing and deployment costs.

Inventive Principle:

Principle #26Copying

3Reliability

If cryptocurrency valuation risks are borne by consumers, then retailers are protected from price fluctuations, but consumer risk exposure increases

Engineering Contradiction:

Improveretailer protection from price fluctuationsVSAvoidconsumer price valuation risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism where the POS terminal system facilitates cryptocurrency transactions while maintaining retailer protection. The system allows consumers to execute transactions directly through integrated exchange functionality, with the terminal acting as a neutral platform that processes transactions without exposing retailers to price valuation risks.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If transaction processing time varies from seconds to hours, then flexibility in transaction speed is provided, but uncertainty in completion time increases

Engineering Contradiction:

Improvetransaction processing speed flexibilityVSAvoidtransaction completion time uncertainty

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements a dynamic transaction processing system that adapts to different cryptocurrency types and transaction amounts. The interface allows consumers to select from various transaction options with different processing times, providing flexibility while managing expectations through transparent time estimates for each transaction type.

Inventive Principle:

Principle #15Dynamics
