Solution Overview

Problem

Standard communication protocols impose limitations on the number of addressable devices due to limited address spaces, which restricts the scalability of distributed data acquisition systems in various environments.

Innovation Solution

A method of addressing frames to target devices by splitting the device address into two parts, where the first part is allocated in the address part of the frame and the second part is allocated in the payload data part, thereby expanding the addressable device range beyond the limitations of the standard protocol.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard communication protocols with dedicated address fields are used, then implementation simplicity and reliability are improved, but the number of addressable devices is limited due to restricted address space

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidnumber of addressable devices

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device address is segmented into two distinct parts: a first part allocated in the dedicated address field of the frame, and a second part allocated in the payload data field. This segmentation allows the address space to be extended beyond the limitations of the standard protocol's address field while maintaining compatibility with existing communication frameworks

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solution transitions from a single-dimensional address field to a two-dimensional addressing scheme by utilizing both the address field and the payload data field. This dimensional expansion effectively multiplies the addressable device capacity without requiring protocol modification

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the address space is expanded to accommodate more devices, then the number of addressable devices is improved, but the protocol complexity increases

Engineering Contradiction:

Improvenumber of addressable devicesVSAvoidprotocol complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system maintains self-service compatibility with standard protocols by using existing frame structures (address field and payload field) without requiring external protocol modifications. The extended addressing mechanism serves itself by utilizing unused or existing payload space, avoiding the need for complex protocol extensions

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If standard hardware modules are used for communication, then cost and power consumption are reduced, but the address space limitation is imposed

Engineering Contradiction:

Improvemanufacturing costVSAvoidaddress space

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The standard communication hardware modules perform multiple functions: they handle both traditional addressing in the address field and extended addressing through the payload field. This multi-functionality allows existing cost-effective hardware to support expanded address spaces without requiring specialized or expensive custom hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Addressing a frame to a target device, the frame being one of a protocol that defines the frame with at least an address part and a payload data part, including obtaining an address of the target device, splitting the address into a first part and a second part, allocating the first part in the address part of the frame, and allocating the second part in the payload data part of the frame.
