Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature measuring devices for roller surfaces face challenges in achieving accurate and reliable temperature measurements across the entire length of the roller surface, particularly due to uneven recesses and vibrations, which can lead to unreliable mechanical and thermal contact.
Innovation Solution
A measuring device with a mounting rod featuring spaced temperature sensors and springy supporting elements, along with a protective sleeve containing a wireless communication, energy supply, and processing unit, ensures a defined contact force and improved mechanical and thermal coupling, allowing for precise temperature measurement and stability during roller operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are placed on a circuit board inserted into a recess, then temperature values can be recorded across the roller surface, but reliable mechanical contact and thermal coupling cannot be ensured due to recess unevenness and vibrations
Solution Approach 1:
The mounting rod is designed to be springy between supporting elements, allowing it to dynamically adapt to recess unevenness and maintain reliable contact despite vibrations. This dynamic flexibility enables the temperature sensor to remain in stable thermal coupling with the roller surface throughout operation.
Solution Approach 2:
The springy mounting rod changes its physical state between insertion (rigid for positioning) and operation (flexible for contact). This parameter change allows the same component to provide both precise positioning during installation and reliable thermal coupling during operation, resolving the contradiction between measurement precision and contact reliability.
2Stability of the object's composition
If the measuring device is firmly fixed in the recess, then position stability is improved, but the device cannot compensate for recess unevenness
Solution Approach 1:
The mounting rod is segmented into different functional zones: rigid end sections for stable positioning and a springy intermediate section for compensating recess unevenness. This segmentation allows the device to simultaneously achieve position stability and adaptability to manufacturing variations.
Solution Approach 2:
The springy portion of the mounting rod acts as an intermediary element between the rigid supporting elements and the temperature sensor. This intermediary provides both mechanical support for stability and flexibility for compensating recess unevenness, resolving the contradiction between position stability and manufacturing precision tolerance.
3Area of stationary object
If multiple temperature sensors are spaced along the roller length, then temperature measurement across the entire surface is achieved, but device complexity increases
Solution Approach 1:
The mounting rod serves multiple functions simultaneously: it provides mechanical support for multiple sensors, enables thermal coupling for each sensor, compensates for recess unevenness, and maintains position stability. This multi-functionality reduces overall device complexity compared to using separate components for each function.
Solution Approach 2:
The mounting rod combines positioning, support, and thermal coupling functions into a single integrated component. By merging these functions rather than using separate components, the device achieves comprehensive temperature measurement coverage while minimizing structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables reliable temperature measurement across the roller surface, compensates for recess unevenness, maintains stability under vibrations, and extends the device's service life by ensuring secure mechanical and thermal contact, while protecting electronic components from environmental factors.
Implementation Method 1
Between the supporting elements, the mounting rod is designed to be springy in such a way that each of the temperature sensors can be pressed onto an inner wall of the recess with a defined contact force
Implementation Method 2
a reliable mechanical contact is equivalent to a reliable thermal coupling between the inner wall of the recess, which has approximately the temperature of the roller surface, and the respective temperature sensor
