Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brake bleeding process in vehicle manufacturing is time-consuming and space-intensive, as it requires filling and bleeding brake apply modules with brake fluid during assembly, which slows down the manufacturing process.
Innovation Solution
A brake bleeding system that includes a brake apply module with a reservoir, a caliper, a pump, and a bleed screw, where a brake bleed module automatically pumps brake fluid and bleeds air from the module upon user input, minimizing the need for manual intervention and optimizing space in manufacturing plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brake apply modules are filled and bled with brake fluid during assembly, then the brakes are ready for use, but the manufacturing process becomes time-consuming and space-intensive
Solution Approach 1:
The brake apply modules are pre-filled with brake fluid before installation in the vehicle. This preliminary action allows the modules to be prepared in advance, eliminating the need for time-consuming filling and bleeding operations during the vehicle assembly process, thus reducing manufacturing time while ensuring brake readiness
2Reliability
If manual bleeding of brake apply modules is performed, then air is removed from the system, but the process requires significant space and manual intervention in manufacturing plants
Solution Approach 1:
The brake apply module includes an integrated pump that automatically pumps brake fluid through the system to bleed air from the calipers. This self-service capability eliminates the need for external manual bleeding equipment and operations, simplifying the manufacturing process while ensuring complete air removal from the brake system
3Productivity
If brake apply modules are pre-filled with brake fluid, then manufacturing throughput increases, but automated bleeding capability is required to maintain efficiency
Solution Approach 1:
The brake apply module is equipped with an integrated pump that automatically performs the bleeding function. This self-service automation enables high-speed pre-filling and bleeding operations without requiring external automated bleeding equipment, thereby maintaining high manufacturing throughput while incorporating necessary automation
