Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional networking protocols and infrastructure are used for one-way streaming, then reliable data communication is achieved, but system complexity and latency increase

Engineering Contradiction:

Improvedata communication reliabilityVSAvoidnetworking infrastructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the need for complex networking infrastructure (routers, switches, private LANs) by using direct RF broadcast communication. The system takes out the intermediate networking layers and protocols, allowing transmitting devices to communicate directly with receiving devices through RF channels, thereby reducing system complexity while maintaining communication reliability through the use of standardized RF communication protocols

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using traditional client-server or peer-to-peer networking models that require complex protocol stacks and infrastructure, the patent inverts the approach by using broadcast-style RF communication where one device can transmit to multiple devices simultaneously. This inversion simplifies the communication model by eliminating the need for handshaking, connection management, and complex routing protocols

Inventive Principle:

Principle #13The other way round (Inversion)

2Quantity of substance

If traditional networking protocols are used for one-way streaming, then data can be transmitted to multiple devices, but latency increases

Engineering Contradiction:

Improvenumber of receiving devicesVSAvoidcommunication latency

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent merges the transmission to multiple devices into a single RF broadcast signal. Instead of establishing separate communication channels to each receiving device (which would increase latency), the system combines all transmissions into one broadcast that reaches multiple devices simultaneously, thereby reducing latency while maintaining the ability to communicate with multiple devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary configuration by assigning unique addresses to receiving devices in advance. This preliminary addressing allows the broadcast system to efficiently route and deliver messages to specific devices or groups without requiring real-time negotiation or protocol handshaking, thereby reducing communication latency

Inventive Principle:

Principle #10Preliminary action

3Reliability

If private local area networks are used for direct communication, then reliable data transmission is achieved, but system complexity and infrastructure requirements increase

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidsystem deployment simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts and removes the requirement for private LAN infrastructure (routers, switches, cabling) by using direct RF broadcast communication. The system achieves reliable data transmission without needing to deploy complex networking infrastructure, thereby simplifying system deployment and manufacturing while maintaining transmission reliability through error correction and acknowledgment protocols

Inventive Principle:

Principle #2Taking out (Extraction)
