Solution Overview

Problem

Existing data provision systems face challenges in combining position data and additional data, such as vibration or temperature data, from different sensors with different measurement principles and sampling frequencies, leading to unclear relationships between the data sets, which complicates their use in motor control or regulation systems.

Innovation Solution

A data provision device with a signal processing unit that receives and combines position data and additional data, bringing them into a defined temporal or position-based relationship before transmission to a higher-level unit, ensuring synchronized and accurate data usage for control or regulation purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If position data and additional data are acquired independently with different sampling frequencies, then data acquisition flexibility is improved, but data synchronization and temporal relationship definition deteriorate

Engineering Contradiction:
Improvedata acquisition flexibilityVSAvoiddata synchronization
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by introducing a trigger signal mechanism that pre-establishes the temporal relationship between position data and additional data acquisition. The trigger signal is generated based on position data and precedes the acquisition of additional data, ensuring that both data types are synchronized to the same reference point before being combined for transmission. This resolves the synchronization issue while preserving independent acquisition flexibility.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If data from multiple acquisition devices are combined for joint transmission, then connection complexity at the higher-level unit is reduced, but data relationship clarity deteriorates

Engineering Contradiction:
Improveconnection complexityVSAvoiddata relationship clarity
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary data processing unit that receives both position data and additional data, establishes their temporal relationships using trigger signals, and combines them into a synchronized data package. This intermediary component maintains data relationship clarity while enabling joint transmission, thereby reducing connection complexity at the higher-level unit without losing information about data relationships.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If additional data are transmitted with time delay or in bulk, then transmission efficiency is improved, but real-time data accuracy deteriorates

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidreal-time data accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements periodic action through a structured trigger signal mechanism that periodically synchronizes data acquisition and transmission. Rather than continuous transmission or delayed bulk transmission, the system uses periodic trigger signals based on position data to initiate additional data acquisition and transmission, achieving both transmission efficiency and real-time accuracy by transmitting data in synchronized periodic cycles.

Inventive Principle:
Principle #19Periodic action

AI summary

A data provision device for providing position data and additional data to a higher-level unit comprises a signal processing unit configured to receive position data and additional data, combine the position data and the additional data for joint data transmission, and then output them together. The data provision device further comprises a signal processing unit configured to receive position data from a position acquisition device and additional data from an additional data acquisition device, to establish a defined, preferably temporal, relationship to the position data, and then output at least the additional data to the signal processing unit.
