Solenoid Valve Controller Elastomer Mounting for ABS Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solenoid valve controllers for hydraulic brake systems in vehicles face challenges in simple assembly, exact positioning of magnet coil yokes, and thermal stability, with previous methods being time-consuming, costly, and prone to temperature-related losses in resilience.
Innovation Solution
The use of elastomer elements to provide a resilient force for magnet coil yokes, which are directly connected to an intermediate base and form a connected web with the seal, ensuring play-free mounting and increased thermal stability up to 180°C, eliminating the need for separate resilient elements and complex casting processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnet coil yokes are cast with thermoplastic elastomer to provide resilient force and sealing, then sealing function is achieved, but the manufacturing process becomes time-consuming and complex
Solution Approach 1:
The patent separates the sealing function from the resilient mounting function by using distinct components: a seal element for sealing and a resilient element (spring) for mounting pressure. This segmentation allows each component to be manufactured independently using simpler processes, eliminating the need for complex casting operations while maintaining both sealing reliability and resilient mounting.
2Ease of operation
If separate plastic resilient elements are used to provide resilient force to magnet coil yokes, then assembly flexibility is improved, but the elements can break and reduce maximum operating temperature
Solution Approach 1:
The patent changes the material parameter from plastic to metal for the resilient element (spring). This parameter change enables the resilient element to withstand higher temperatures (improving thermal stability) while maintaining its elastic properties. The metal spring provides reliable resilient force without the temperature limitations of plastic materials, and its simple structure prevents breaking issues.
3Stability of the object's composition
If complex casting processes are used to integrate magnet coil yokes with resilient mounting, then structural integration is achieved, but production costs increase
Solution Approach 1:
The patent merges the seal element and resilient element into a single integrated sealing component that performs both sealing and resilient mounting functions. This merging eliminates the need for complex casting processes to achieve structural integration, as the combined component can be manufactured using simpler processes like injection molding or stamping, thereby reducing production costs while maintaining structural integrity.

AI summary
A solenoid valve controller (100) for an ABS/ESP of a motor vehicle is rigidly connected to a hydraulic device (200) by an elastomer element arranged on a base (112) of a control housing (110) of the solenoid valve controller (100). A magnet coil yoke (130) is provided on the elastomer element (120) so that the magnet coil yoke (130) is pushed directly onto an outer side of the hydraulic device (200) by the elastomer element (120) with the control housing (110) and in so doing receives a solenoid valve unit (230) of the hydraulic device (200) . The elastomer element (120) serves as a bearing and an outer side of the hydraulic device (200) serves as an abutment for the magnet coil yoke (130) . As a result, the magnet coil yoke (130) can be fixed without play in the control housing.
