Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic token transaction systems restrict offline transactions for users without an ID, excluding merchants and leading to blocked transactions exceeding token limits, hindering the flow of monetary values.

Innovation Solution

A secure token transaction unit with an offline token receiving and storage unit that allows for restricted spendability of received offline tokens, enabling both users and merchants to use offline transactions without blocking, and includes a collector mode with a higher token limit compared to normal mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If offline token limits are imposed for risk management, then security is improved, but transaction flow is hindered due to blocking of exceeding transactions

Engineering Contradiction:

Improverisk managementVSAvoidtransaction flow

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments the token transaction system into two distinct modes: normal mode with standard token limits for risk management, and collector mode with elevated token limits for high-volume transactions. This segmentation allows the system to maintain security through limit enforcement while enabling uninterrupted transaction flow when operating in collector mode, thereby resolving the contradiction between risk management and transaction productivity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic switching between normal mode and collector mode based on transaction requirements. The token limit is not fixed but dynamically adjusted: in normal mode, standard limits apply for risk control; in collector mode, higher limits are imposed to accommodate large transaction volumes without blocking. This dynamic adaptation resolves the contradiction by allowing the system to optimize for either security or productivity depending on operational context

Inventive Principle:

Principle #15Dynamics

2Reliability

If offline transactions are restricted to users with ID, then security is improved, but versatility is reduced by excluding merchants and companies

Engineering Contradiction:

ImprovesecurityVSAvoidparticipant eligibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal offline transaction mechanism that functions for all participant types (users, merchants, companies) regardless of ID status. The collector mode with elevated token limits enables merchants and companies to engage in offline transactions without requiring traditional ID verification, while the system maintains security through alternative risk management approaches. This universality resolves the contradiction by making the system adaptable to diverse participant needs while preserving security through modified operational modes

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A secure token transaction unit (STU) comprising: an offline token receiving unit (101) configured for receiving at least one offline token of an electronic token transaction system (TS) from at least one other secure token transaction unit (ASTU) of the electronic token transaction system (TS); an offline token storage unit (102) configured for storing the received at least one offline token of the electronic token transaction system (TS); wherein in a collector mode of the secure token transaction unit (STU), the received offline token is stored such that its spendability is restricted.
