Detachable Thermopile Support for Heating Roller Temperature Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying devices for inkjet recording apparatuses face challenges in accurately detecting and controlling the surface temperature of heating rollers, leading to inconsistent drying processes and reduced durability of ink fixation.
Innovation Solution
A supporting structure for a temperature sensor is introduced, featuring a first supporting member with detachable second members that securely position a thermopile unit between the front and rear panels of the drying device, allowing precise temperature detection and easy maintenance, while also optimizing the flow of cooling air for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed supporting structure is used for the temperature sensor, then the temperature detection position is stable, but the maintenance and replacement of the sensor becomes difficult
Solution Approach 1:
The supporting structure is divided into a first supporting member that is fixed to the housing and a second supporting member that can be detached from the first. The temperature sensor is mounted on the detachable second supporting member, allowing the sensor to be easily removed and replaced while maintaining a stable detection position when installed.
Solution Approach 2:
The supporting structure transitions from a completely fixed design to a dynamic system where the second supporting member can be detached. This allows the structure to adapt between providing stable support during operation and enabling easy access for maintenance, resolving the contradiction between stability and serviceability.
2Device complexity
If the temperature sensor is directly fixed to the housing, then the structure is simple, but the sensor cannot be easily removed for maintenance
Solution Approach 1:
The supporting structure is segmented into two distinct members: a first supporting member fixed to the housing and a second supporting member that can be detached. This segmentation adds minimal complexity while dramatically improving maintenance accessibility, as the sensor can be accessed by removing only the second member rather than disassembling the entire structure.
3Device complexity
If the temperature sensor position is not precisely controlled, then the structure is simpler, but the temperature detection accuracy decreases
Solution Approach 1:
The second supporting member acts as an intermediary between the fixed first supporting member and the temperature sensor. It includes a positioning portion that precisely positions the sensor while allowing the sensor to be easily attached and detached. This intermediary structure provides precise positioning without requiring complex adjustment mechanisms.

AI summary
A supporting structure for a temperature sensor, and a drying device provided with the supporting structure. The supporting structure includes a front panel, a rear panel, a first supporting member having both ends in a longer-side direction of the first supporting member, and a second supporting member attachable to and detachable from the first supporting member. In the supporting structure, both ends of the first supporting member are removably supported by the front panel and the rear panel. In the supporting structure, the temperature sensor is disposed on the second supporting member, and the temperature sensor detects a surface temperature of a heating roller disposed between the front panel and the rear panel.
