Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional control instruction transmission methods are used between devices over long distances, then the transmission can be established, but the transmission delay becomes excessively long

Engineering Contradiction:

Improvetransmission delayVSAvoiduser experience quality

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent replaces traditional TCP-based control instruction transmission with UDP packet transmission. UDP is a lighter-weight protocol that does not perform complex error checking and retransmission, thereby reducing transmission delay while maintaining sufficient reliability for control instructions. This substitution of transmission protocol directly addresses the contradiction by prioritizing speed over comprehensive error handling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the transmission parameter from TCP protocol to UDP protocol. This parameter change fundamentally alters the transmission characteristics, reducing overhead and processing time while accepting a trade-off in error handling complexity. The parameter change enables ultra-low latency transmission suitable for remote control scenarios.

Inventive Principle:

Principle #35Parameter changes

2Speed

If UDP protocol is used for control instruction transmission, then transmission latency is reduced, but error handling capability may be compromised

Engineering Contradiction:

Improvetransmission speedVSAvoiderror handling capability

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent introduces an intermediary mechanism where the transmitting device encapsulates control instructions in UDP packets with appropriate protocol headers, and the receiving device decapsulates and processes them. This intermediary UDP protocol layer provides a balance between speed and reliability, offering faster transmission than TCP while including basic error handling capabilities through its protocol structure.

AI summary

Disclosed is a transmitting method for a control instruction in long-distance transmission. The transmitting method includes the follows. A transmitting device obtains a first control instruction. The transmitting device encapsulates the first control instruction through a user datagram protocol (UDP) protocol to obtain a UDP packet. The transmitting device transmits the UDP packet to a first communication module via an input interface of the first communication module. With this disclosure, ultra-low latency transmission of the control instruction between devices in long-distance transmission can be achieved.
