Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure sensors in vehicle braking systems are not cost-effective and lack miniaturization, requiring larger installation spaces and not being robust enough for long service life.
Innovation Solution
A compact pressure sensor design with a pressure measuring cell having a contact surface angled relative to its center axis, combined with a circuit mount at the same angle, and using bonding contacts for reliable electrical connections, along with a protective sleeve and MID component technology, allows for further miniaturization and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pressure sensors are designed with conventional centralized layouts, then structural simplicity is maintained, but installation space requirements increase and miniaturization is limited
Solution Approach 1:
The contact surface of the pressure measuring cell is arranged at an angle relative to the center axis of the pressure sensor, transitioning from a conventional axial arrangement to an inclined spatial configuration. This dimensional change enables more efficient space utilization and reduces the overall installation footprint while maintaining functional integrity
Solution Approach 2:
The circuit mount is integrated directly with the pressure measuring cell structure, with contact areas formed on the same component that provides both mechanical support and electrical connection functions. This merging of structural and electrical functions eliminates the need for separate supporting elements and reduces overall device volume
2Volume of moving object
If pressure sensors are miniaturized to reduce installation space, then space efficiency improves, but mechanical strength and reliability may deteriorate
Solution Approach 1:
The pressure sensor employs a composite structure combining a diaphragm made of elastomeric material with a circuit mount providing mechanical support. This composite design enables the small pressure measuring cell to maintain high mechanical strength while achieving miniaturization, as the elastomeric diaphragm provides flexibility and strength where needed without requiring large supporting structures
3Volume of moving object
If pressure sensors are miniaturized for compact installation, then installation space is reduced, but electrical connection reliability may worsen
Solution Approach 1:
The circuit mount is designed with contact areas that are integrated into the same component structure that provides mechanical support for the pressure measuring cell. This merging of structural and electrical functions ensures that electrical connections are maintained through robust mechanical bonding rather than separate connection elements, thereby ensuring reliability in the miniaturized design
Solution Approach 2:
The circuit mount features contact areas with specific local properties optimized for electrical connection, arranged at angles matching the contact surface orientation. This localized optimization of contact area geometry and positioning ensures reliable electrical connections are achieved within the constrained space of the miniaturized sensor

AI summary
A pressure sensor for detecting a pressure of a medium, in particular for a braking apparatus, includes a connecting flange having a fluid channel for connection to the medium which is to be measured, a pressure measuring cell which is arranged at the end of the fluid channel, and a circuit mount, with the pressure measuring cell having a contact surface for making contact. The contact surface is arranged at an angle relative to a center axis of the pressure sensor.
