Measurement Sensor With Deposit Basin For Coating Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure and temperature sensors face challenges in protecting sensitive components from external attacks, such as acid condensates, due to the risk of coating materials like thermosetting resin covering measurement components during the coating process, which is difficult to control and results in complex and expensive manufacturing processes.
Innovation Solution
A measurement sensor design featuring a deposit basin with a volume to receive all coating material before it flows into the cavity, along with separate purge orifices to evacuate air and prevent resin from covering the measurement components, ensuring the components remain exposed and functional.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If coating material is injected into the cavity to protect sensitive components, then protection of sensitive components is improved, but measurement component may be covered and functionality is lost
Solution Approach 1:
The cavity is segmented into two distinct zones: a deposit basin zone for receiving and containing the coating material, and a measurement zone for housing the measurement component. This spatial segmentation ensures that the coating material remains confined to the deposit basin and cannot cover the measurement component, thus protecting sensitive components while maintaining measurement functionality.
Solution Approach 2:
The deposit basin acts as an intermediary structure between the coating material injection system and the measurement component. It serves as a buffer zone that receives the coating material and prevents it from reaching the measurement component, thereby mediating the conflict between protection and functionality.
2Reliability
If injection pressure and viscosity are controlled to prevent coating material from covering measurement component, then measurement component functionality is maintained, but manufacturing process becomes complex and expensive
Solution Approach 1:
The deposit basin is pre-configured in the cavity structure before the coating material is injected. This preliminary arrangement of the cavity structure ensures that the coating material has a designated receptacle from the outset, eliminating the need for complex real-time control of injection parameters to prevent overspill onto the measurement component.
Solution Approach 2:
The potential problem of coating material overspill is extracted and isolated into a separate deposit basin structure. By removing the risk of measurement component coverage from the main injection process, the manufacturing process becomes simpler and less expensive, as complex parameter control is no longer required.
3Manufacturing precision
If air evacuation zone is provided to remove air during coating material flow, then coating quality is improved, but device structure becomes more complex
Solution Approach 1:
The deposit basin serves multiple functions: it receives the coating material, contains it to prevent overspill, and acts as an air evacuation zone. By combining these functions into a single structure, the device complexity is minimized while still achieving improved coating quality through effective air removal during the filling process.
