Brake Pulsation Dampener Assembly With Single-Cap Support Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic hydraulic brake apparatuses for vehicles face increased production costs and extended assembly times due to the requirement of damper caps on both sides of the pulsation dampener, which complicates the assembly process.
Innovation Solution
The braking apparatus incorporates a pulsation dampener with a support ring instead of a damper cap, simplifying the assembly process and reducing production costs by interconnecting the first and second flow paths to mitigate hydraulic pressure differences and pulsation phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If damper caps are installed on both sides of the pulsation dampener, then the pulsation dampener can effectively mitigate hydraulic pressure pulsation, but the production cost increases and assembly time extends
Solution Approach 1:
The patent removes one damper cap from the pulsation dampener structure, extracting the unnecessary component while maintaining the essential pulsation mitigation function through the modified single-cap design and support ring configuration
Solution Approach 2:
The patent combines the functions of the removed damper cap with the support ring structure, integrating the support and pulsation mitigation functions into existing components rather than requiring separate dedicated parts
2Reliability
If damper caps are installed on both sides of the pulsation dampener, then the pulsation dampener can effectively mitigate hydraulic pressure pulsation, but the production cost increases
Solution Approach 1:
The patent removes one damper cap from the pulsation dampener structure, extracting the unnecessary component while maintaining the essential pulsation mitigation function through the modified single-cap design and support ring configuration
Solution Approach 2:
The patent discards the redundant damper cap component, eliminating material costs and manufacturing expenses associated with producing and installing unnecessary parts while recovering resources through simplified production processes
3Reliability

Solution Approach 1:
The patent removes one damper cap from the pulsation dampener structure, extracting the unnecessary component while maintaining the essential pulsation mitigation function through the modified single-cap design and support ring configuration
Solution Approach 2:
The patent skips the assembly step of installing a second damper cap, reducing the number of assembly operations required while still achieving the necessary pulsation mitigation performance through the optimized single-cap configuration
