Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate high-speed counter units and analogue units are used for processing pulse and analogue signals, then signal processing capability is improved, but cost and space requirements increase

Engineering Contradiction:
Improvesignal processing capabilityVSAvoidnumber of separate devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the high-speed counter unit and analogue unit into a single integrated device. The counter unit and analogue unit share common resources including the CPU, memory, communication interface, and housing, allowing both pulse signal counting and analogue signal processing to be performed by one device rather than requiring separate units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device is designed to perform multiple functions: it can count pulse signals from encoders or other pulse sources, process analogue signals from various sensors, and provide communication interfaces. This multi-functional design eliminates the need for separate dedicated counter and analogue devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Speed

If separate counter and analogue units are prepared, then processing speed for pulse signals is maintained, but installation space increases

Engineering Contradiction:
Improvepulse signal processing speedVSAvoidinstallation space
Core Design Contradiction:
SpeedVSArea of stationary object

Solution Approach 1:

The counter unit and analogue unit are merged into a single physical device with shared internal resources. The high-speed counting function is maintained through dedicated counting circuits within the integrated device, while the overall footprint is reduced by eliminating the need for two separate device installations.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If separate counter and analogue units are used, then functional reliability is improved, but system cost increases

Engineering Contradiction:
Improvesignal processing reliabilityVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple signal processing functions into one device while maintaining reliability through proper internal architecture. The counter unit and analogue unit operate with dedicated processing paths within the integrated device, and shared resources like the CPU and communication interface are managed efficiently to ensure reliable operation of both functions simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

In order to save on costs and space when processing analogue signals and pulse signals, a signal measurement unit (2) comprises: an input unit (21) which inputs an electrical signal from a device and selects whether to transmit the signal to an analogue measurement unit (22) or a counting measurement unit (23); the analogue measurement unit which measures voltage as an analogue value; and the counting measurement unit which counts the number of times that the voltage value has equaled or exceeded a first threshold value or the number of times that the voltage value has equaled or fallen below a second threshold value.
