Solution Overview

Problem

Existing temperature control systems for devices, such as filling level measuring devices, require complex and costly adaptations due to their irregular surface structures, which complicates effective cooling or heating processes.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional temperature control system is used with irregular surface structures, then thermal contact is poor, but the device complexity and cost increase due to complex adaptations

Engineering Contradiction:
Improvethermal contact qualityVSAvoidsystem complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The heat sink is made deformable rather than rigid, allowing it to dynamically adapt its shape to match irregular surface contours. This dynamic adaptation enables the heat sink to conform to complex geometries without requiring complex rigid structural adaptations, thereby improving thermal contact while maintaining system simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the physical state of the heat sink from rigid to deformable, fundamentally altering its mechanical properties. This parameter change allows the heat sink to passively adapt to surface irregularities through material deformation rather than requiring complex mechanical adjustments or custom-fitted rigid structures

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If the heat sink is made rigid for structural stability, then manufacturing is easier, but thermal contact with irregular surfaces deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidthermal conductivity
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The heat sink material properties are changed from rigid to deformable, allowing it to naturally conform to surface irregularities. This single parameter change simultaneously improves thermal contact quality while maintaining manufacturing simplicity, as the deformable material can be produced using standard fabrication processes without complex assembly requirements

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The heat sink is designed as a deformable structure that can flex and conform to irregular surfaces. This flexible design approach maintains ease of manufacture through simple geometric forms while dramatically improving thermal contact area and quality on complex surface geometries

Inventive Principle:
Principle #30Flexible shells and thin films

3Temperature

If cooling fluid pressure is increased to improve thermal contact, then heat transfer efficiency improves, but the risk of damaging the detector increases

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoiddetector damage risk
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The deformable heat sink provides a compliant interface that dynamically adapts to the detector surface, distributing cooling fluid pressure evenly across the contact area. This dynamic adaptation prevents localized pressure concentration that could damage the detector, while still achieving high heat transfer efficiency through improved contact area

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The deformable heat sink material acts as a cushioning element between the high-pressure cooling fluid and the detector surface. This cushioning effect absorbs and distributes the mechanical stress from pressurized cooling fluid, protecting the detector from damage while maintaining effective thermal contact

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The compress (200) has a cooling body made of a deformable material and attached to a detector of a level measuring device. The cooling body is configured for through-flow of a cooling fluid (205). A region of an inner wall (204) of the cooling body moves toward a corresponding region of an outer surface of the detector to form a thermal contact with the corresponding region, when the compress is attached to the detector and when the fluid flows through the cooling body. A fastening device e.g. strap, holds the cooling compress on a detector housing (201). Independent claims are also included for the following: (1) a level measuring device (2) a method for controlling temperature of a detector using a cooling compress.
