Honeycomb Heater with Integrated Performance Data Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric-heating-type heaters for catalyst converters lack integrated management of heater performance information, leading to laborious record-keeping and potential misidentification or loss of data, which complicates failure detection and energization control.
Innovation Solution
An information-display-equipped electric-heating-type heater with a circumferential coating layer on the honeycomb structure displays performance metrics like resistance value, NTC characteristics, and heat generation speed, allowing direct reading and utilization of this information for failure detection, deterioration monitoring, and energization control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If heater performance information is recorded externally on paper or separate media, then the information can be stored, but misidentification and loss of information occur and management becomes laborious
Solution Approach 1:
The patent merges the heater performance information directly with the heater device by forming a coating layer on the heater surface that contains the information. This integration ensures the information cannot be lost or misidentified separately from the heater it describes, eliminating the problems of external record-keeping while maintaining easy access to the data.
2Ease of operation
If a coating layer is formed on the honeycomb structure to display information, then information management is simplified, but the coating layer may interfere with electrode function if too close
Solution Approach 1:
The patent applies local quality by positioning the coating layer containing information at a specific distance (0.1 mm or more) from the electrodes. This localized placement ensures the coating does not interfere with electrode electrical function while still being visible for information display, thus maintaining both reliability of electrode operation and ease of information management.
