Solution Overview

Problem

Low-powered or remotely-located devices struggle to maintain synchronization with a blockchain due to energy and connectivity constraints, limiting the applicability of blockchain technology for these devices.

Innovation Solution

Broadcasting blockchain updates using radiofrequency signals, allowing devices to passively receive and store synchronization information, and authenticate data for uploading when internet connectivity is restored.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a device maintains an active internet connection to synchronize with the blockchain, then synchronization reliability is improved, but energy consumption increases

Engineering Contradiction:

Improvesynchronization reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic broadcast signals transmitted at regular intervals (e.g., every few seconds) to update device states. Devices can enter low-power modes between broadcasts and wake to receive updates, achieving synchronization without maintaining continuous active connections, thus reducing energy consumption while maintaining reliability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

A broadcast intermediary system transmits blockchain state updates via RF signals to multiple devices simultaneously. This intermediary handles the complex task of maintaining blockchain state information and distributing it periodically, allowing individual devices to conserve energy while staying synchronized through passive reception

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If a device downloads a large amount of information from the internet to synchronize with the blockchain, then synchronization completeness is improved, but data transmission time increases

Engineering Contradiction:

Improvesynchronization completenessVSAvoiddata transmission time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system creates simplified copies of blockchain state information that can be transmitted efficiently via broadcast signals. Instead of downloading complete blockchain data, devices receive essential state updates (block headers, transaction summaries) that are sufficient for synchronization, reducing transmission time while maintaining completeness

Inventive Principle:

Principle #26Copying

Solution Approach 2:

Blockchain state information is prepared and staged in advance for broadcast. The system pre-processes and formats synchronization data before transmission, so when broadcast signals are transmitted, devices can quickly receive and process the information without delays associated with real-time data preparation and compression

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a device maintains an active internet connection to synchronize with the blockchain, then synchronization reliability is improved, but device complexity increases

Engineering Contradiction:

Improvesynchronization reliabilityVSAvoidconnection management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The broadcast system automatically manages synchronization by periodically transmitting state updates without requiring devices to actively manage connections. Devices simply listen for broadcasts and update their local state, eliminating complex connection management, handshaking, and error recovery protocols while maintaining reliable synchronization

Inventive Principle:

Principle #25Self-service

4Productivity

If low-powered devices use signal transmission to communicate with the blockchain, then data writing capability is improved, but power consumption increases

Engineering Contradiction:

Improvedata writing capabilityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

Instead of devices actively transmitting data to the blockchain, the system inverts the communication direction: blockchain state information is broadcast to devices via RF signals. This allows devices to receive synchronization data passively with minimal power consumption, while still enabling them to write data when connectivity is available

Inventive Principle:

Principle #13The other way round (Inversion)
