Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If temperature sensors are integrated directly into injection-molded hose couplings, then the sensors can be firmly integrated into the media-carrying hose line, but the injection-molded parts must be individually designed for each sensor type, significantly increasing part variety and manufacturing complexity

Engineering Contradiction:
Improvefirm integration of temperature sensorVSAvoidpart variety and manufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The temperature sensor is divided into separate components: a sensor element and a mounting adapter. The adapter is designed as a universal component that can accommodate different sensor types, while the sensor element remains interchangeable. This segmentation allows the sensor to be firmly integrated without requiring individual customization of the entire assembly for each sensor type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting adapter is designed as a universal component that can accommodate multiple types of temperature sensors (e.g., NTC thermistors, Pt100, Pt1000). The adapter provides a standardized interface with the injection-molded hose coupling, allowing the same adapter design to work with various sensor types, thereby reducing part variety and manufacturing complexity.

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

2Strength

If glass fiber reinforced plastic is used to increase the strength of hose couplings, then the coupling strength is improved, but the thermal conductivity of the material is reduced, impairing the response time and accuracy of the temperature sensor

Engineering Contradiction:
Improvehose coupling strengthVSAvoidtemperature sensor accuracy and response time
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

A thermally conductive intermediary material (such as thermal paste or a metal transition piece) is introduced between the temperature sensor and the glass fiber reinforced plastic housing. This intermediary compensates for the poor thermal conductivity of the composite material, ensuring efficient heat transfer from the medium to the sensor while allowing the housing to maintain its structural strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The housing is made from glass fiber reinforced plastic to provide mechanical strength, while a thermally conductive material is used for the sensor mounting interface or transition piece. This composite approach allows the structure to maintain strength while the sensor interface optimizes thermal conductivity for accurate temperature measurement.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If temperature sensors are integrated into injection-molded parts, then the sensors can be mounted within the media-carrying hose line, but new materials such as PA66 with glass fiber reinforcement cannot be effectively used due to reduced thermal conductivity

Engineering Contradiction:
Improvematerial selection flexibilityVSAvoidtemperature sensor performance
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The temperature measurement system is segmented into a structural component (housing made from glass fiber reinforced PA66 for versatility and strength) and a thermal interface component (thermally conductive material or metal transition piece). This segmentation allows the use of high-performance engineering plastics while maintaining effective thermal coupling for accurate temperature sensing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A thermally conductive intermediary is introduced at the sensor interface to bridge the thermal gap created by using glass fiber reinforced plastics. This allows the system to benefit from both the material versatility and mechanical properties of reinforced plastics and the thermal conductivity needed for accurate temperature measurement.

Inventive Principle:
Principle #24Intermediary (Mediator)
