Solution Overview

Problem

Conventional temperature monitoring and/or control elements in heating systems experience slow response times due to improper fixation methods, such as screw mounting, leading to inefficient heat transfer and delayed safety responses.

Innovation Solution

The temperature monitoring and/or control elements are directly fixed onto the heating unit using laser welding, with a beveled edge of less than 90°, enhancing thermal contact and reducing the need for additional mounting elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If temperature monitoring and/or control elements are fixed using conventional screw mounting to a mounting plate, then the mounting structure is simple to assemble, but the response time of the temperature elements becomes unacceptably slow

Engineering Contradiction:
Improveresponse timeVSAvoidmounting structure complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The temperature monitoring and/or control element is merged directly with the heating unit by laser welding, eliminating the separate mounting plate and screw fixation structure. This direct integration creates optimal thermal contact and dramatically reduces response time while simplifying the overall mounting structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mechanical screw mounting system is replaced with laser welding technology. This substitution eliminates the thermal resistance introduced by mechanical fasteners and mounting plates, providing direct thermal coupling between the temperature element and heating unit for faster response.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the mounting plate is soldered to the heating unit, then the temperature element can be mounted, but the mounting plate curves and the temperature element is lifted away from the hot location

Engineering Contradiction:
Improvetemperature monitoring reliabilityVSAvoidmounting plate flatness
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The mounting plate is completely removed from the system. The temperature monitoring and/or control element is fixed directly onto the heating unit without any intermediate mounting plate, eliminating the curvature problem and ensuring consistent thermal contact.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The temperature element and heating unit are merged into a single integrated assembly through direct laser welding, eliminating the mounting plate that caused deformation and lifting issues.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If fixing screws are used to mount the temperature element, then the mounting is secure, but the temperature element remains in the air above the hot location and cannot receive heat directly

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoidmounting ease
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

Mechanical screw fixation is replaced with laser welding, enabling direct thermal contact between the temperature element and heating unit. This eliminates the air gap that prevented efficient heat transfer while maintaining secure attachment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The laser weld seam acts as an intermediary that provides both mechanical fixation and optimal thermal contact, eliminating the need for separate fixing screws that created air gaps and thermal resistance.

Inventive Principle:
Principle #24Intermediary (Mediator)
