Solution Overview

Problem

Existing test systems for simulating environmental temperature influences on mechanical components deteriorate over time, leading to instability and lack of reproducibility in test scenarios.

Innovation Solution

A test system with a platform and heating/cooling fluid providing means, where the fluid providing means are reproducibly fixed to the test piece using position means with markings and gratings for precise alignment, allowing adjustable fluid flow angles and nozzle positioning for controlled thermal conditioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If flexible plastic tubes are used to direct heating/cooling fluids towards the test piece, then the test system can be simple and easy to install, but the test scenario deteriorates over time with respect to initially set parameters

Engineering Contradiction:
Improveease of installationVSAvoidtest scenario stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system transitions from static flexible tubes to a dynamic positioning system with adjustable fluid providing means that can be precisely positioned and fixed at different locations around the test piece, allowing the test scenario to be maintained stably over time while remaining easy to install and reconfigure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms through position means with markings and gratings that allow monitoring and adjustment of the fluid providing means position, ensuring the test scenario parameters remain stable and reproducible over time

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the fluid providing means are freely positioned, then the system is flexible and easy to operate, but the relative position cannot be reproducibly fixed

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidposition reproducibility
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The positioning system is segmented into discrete position means with specific markings and gratings that can be independently adjusted and fixed, allowing flexible operation while enabling precise reproduction of relative positions through standardized positioning elements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary positioning actions by establishing predefined position references through markings and gratings before the actual testing, ensuring that the fluid providing means can be reproducibly fixed at desired locations while maintaining operational flexibility

Inventive Principle:
Principle #10Preliminary action
