Solution Overview

Problem

Existing temperature measurement systems for road construction machines struggle to adapt to varying temperature measurement specifications across different countries and states, requiring manual operator intervention to select the correct specifications, which is inefficient and prone to errors.

Innovation Solution

A control unit with a data selector and analyzer that uses position information, such as GPS, to automatically select the correct temperature measurement specification from a database, ensuring compliance with local requirements and generating reports based on national or state-specific standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual operator intervention is used to select temperature measurement specifications, then the system can handle different local requirements, but the process becomes inefficient and prone to errors

Engineering Contradiction:

Improveability to handle different local requirementsVSAvoidefficiency of specification selection

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The control unit automatically selects the appropriate temperature measurement specification by accessing position information from the position sensor and matching it with stored specification data sets, eliminating the need for manual operator intervention and enabling the system to serve itself in adapting to local requirements

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses position information as feedback to automatically determine which local region the road construction machine is in, then selects the corresponding temperature measurement specification from the database, creating a closed-loop adaptive system that responds to changing locations

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If manual operator intervention is used to select temperature measurement specifications, then the system can handle different local requirements, but operator errors increase

Engineering Contradiction:

Improveability to handle different local requirementsVSAvoidaccuracy of specification selection

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The control unit autonomously performs the specification selection task by comparing position information with stored specification data sets, removing human operators from the decision-making process and eliminating the possibility of manual selection errors

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of operator selection is replaced with an automated electronic system that uses position sensors, databases, and control logic to reliably select the correct temperature measurement specification based on the machine's location

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple temperature measurement specifications are stored for different regions, then the system can comply with local regulations, but the device complexity increases

Engineering Contradiction:

Improvecompliance with different local regulationsVSAvoidcomplexity of specification management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit is designed with multi-functionality, serving both as the position information processor and the specification selector, while the database stores multiple specification data sets that can serve any local region, making the system universally applicable across different jurisdictions without requiring region-specific hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple temperature measurement specifications are pre-stored in the database as specification data sets before the road construction machine operates, allowing the control unit to simply retrieve and select the appropriate pre-prepared specification based on current position information, rather than managing complex real-time specification creation

Inventive Principle:

Principle #10Preliminary action

AI summary

A control unit of a temperature measurement system for a road construction machine, wherein the control unit has access to a database, a plurality of specification data sets stored on said database, wherein each of the plurality of specification data sets is assigned to a local region and comprises a temperature measurement specification and/or a temperature measurement report specification, the control unit comprises a data set selector and a data analyzer. The data set selector is configured to select a respective specification data set out of the plurality based on a position information for the road construction machine, the position information pointing to the respective local region. The data analyzer is connected to a temperature sensor and configured to analyze raw data received from the temperature sensor taking into account the selected temperature measurement specification and/or to output a local specific temperature report based on the analyzed raw data taking into account the selected temperature measurement report specification.
