Solution Overview

Problem

Existing measuring probes for metal or slag melts face challenges in simple and cost-effective assembly, particularly due to complex sensor mounting and handling of long signal lines.

Innovation Solution

The measuring probe features lateral recesses and channels on the rear end for sensor mounting, allowing for assembly from one side without rotation, with signal lines guided through these channels and connected to contact pieces for simplified handling and fixation using refractory cement, enabling modular construction and reduced assembly costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If sensors are mounted on the immersion end of the measuring head using conventional methods, then the sensors can be fixed securely, but the assembly process becomes complex and time-consuming requiring rotation of the measuring head and handling of long signal lines

Engineering Contradiction:

Improveassembly processVSAvoidmounting procedure

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent inverts the conventional mounting approach by providing recesses in the rear end of the measuring head (opposite the immersion end) where sensor connections are made. This allows assembly to start from the rear end rather than the immersion end, eliminating the need to rotate the measuring head during assembly and simplifying the mounting procedure.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent segments the measuring head structure by providing separate recesses for each sensor connection on the rear end. Each recess can accommodate individual sensor connections independently, allowing for modular assembly where sensors and their connections are made separately and then integrated into the measuring head without complex rotation operations.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple sensors are arranged on the immersion end, then comprehensive measurements can be performed, but the signal lines become long and difficult to handle during assembly

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidsignal line handling

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent inverts the signal line routing approach by connecting sensors to the rear end of the measuring head rather than directly to the immersion end. This shortens the effective signal line length within the measuring head and makes assembly easier, as connections are made at the accessible rear end rather than requiring manipulation at the immersion end.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces an intermediary structure in the form of recesses on the rear end that serve as connection points between sensors and the measuring head. These recesses act as intermediaries that simplify the connection process, allowing signal lines to be routed more efficiently and reducing the complexity of handling long signal lines during assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If the measuring head is rotated during assembly to mount sensors, then all sides can be accessed, but the assembly time increases and the process becomes more error-prone

Engineering Contradiction:

Improvesensor mountingVSAvoidassembly time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent eliminates the need for rotation during assembly by inverting the mounting approach: instead of accessing the immersion end to mount sensors, all sensor connections are made through recesses on the rear end. This single-sided access approach prevents time loss from rotation operations and reduces assembly errors.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent incorporates connection recesses directly into the rear end structure during manufacturing, preparing the mounting locations in advance. This preliminary action eliminates the need for rotation during assembly, as all necessary connection points are already positioned and accessible on the rear end before the assembly process begins.

Inventive Principle:

Principle #10Preliminary action
