Integrated Pressure Sensor Assembly Without Wire Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure sensors have a large size and poor reliability due to the separation of pressure sensitive components and control circuits, requiring wire connections and separate housings, which complicates assembly and increases volume.
Innovation Solution
Integration of pressure sensitive elements and signal generators on a common substrate, with integrated seals and a compact housing design that eliminates wire connections and includes multiple seals to isolate the components from the ambient environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure sensitive component and control circuit are separated and connected through wire connection, then reliability is improved through isolation, but device volume and overall size increase significantly
Solution Approach 1:
The patent integrates the pressure sensitive component and control circuit onto a single substrate, eliminating the need for wire connections and separate housings. This merging of previously separated components directly reduces device volume while maintaining functional isolation through the substrate structure, resolving the contradiction between reliability through isolation and compact size.
2Reliability
If pressure sensitive component and control circuit are separated into different housings, then reliability is improved through isolation, but device complexity and assembly difficulty increase
Solution Approach 1:
By combining both components on a single substrate with integrated sealing structures, the patent eliminates the need for separate housings and complex wire connections. This integration simplifies the overall device structure and assembly process while maintaining the reliability benefits of isolated component operation through the substrate's inherent separation capabilities.
3Reliability
If wire connections are used to connect pressure sensitive component and control circuit, then reliability is improved through electrical connection, but manufacturing complexity and assembly time increase
Solution Approach 1:
The patent replaces the mechanical wire connection system with a direct substrate-based electrical connection. The substrate serves as both the mechanical support and electrical pathway, eliminating the need for separate wire connections and associated assembly steps. This substitution maintains reliable electrical connectivity while significantly improving manufacturing efficiency and assembly speed.
