Emergency Brake Fluid Backup for Ruptured Brake Pipes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile braking systems are vulnerable to safety-related accidents when the brake pipe ruptures, as they cannot apply a braking force without hydraulic or pneumatic pressure.
Innovation Solution
An emergency braking device is introduced, featuring an emergency pipe filled with emergency brake fluid, a pressing part to press the emergency brake fluid, and a valve unit that blocks the main brake fluid and allows emergency brake fluid to flow when the brake pipe is ruptured, ensuring emergency braking can occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic or pneumatic braking system is used, then normal braking performance is achieved, but the system becomes vulnerable to safety accidents when the brake pipe ruptures
Solution Approach 1:
The emergency brake fluid is pre-filled in the emergency pipe and the pressing part is pre-configured with a piston and pressure source. When normal braking fluid leaks, the system immediately switches to emergency braking without requiring any additional preparation or assembly, enabling rapid response to the hazardous condition
Solution Approach 2:
The emergency braking system acts as a pre-prepared safety cushion against the harmful effect of brake pipe rupture. By having an independent emergency brake fluid system ready in advance, the patent cushions the vehicle against the catastrophic failure mode of hydraulic/pneumatic system rupture, preventing safety accidents
2Reliability
If an emergency braking system with separate emergency pipe and pressing part is added, then safety is improved during pipe rupture, but device complexity increases
Solution Approach 1:
The emergency braking system merges the emergency pipe, pressing part, valve unit, and alarm into a relatively integrated emergency braking assembly. While still adding components to the existing brake system, the merging approach reduces the overall complexity compared to having completely separate systems, and enables coordinated operation of all emergency components
Solution Approach 2:
The valve unit serves as an intermediary component that selectively connects or disconnects the emergency pipe from the brake pipe based on system conditions. This intermediary mechanism simplifies the overall system architecture by providing a controlled interface between the normal and emergency braking systems, rather than requiring complex switching mechanisms
3Reliability
If the valve unit blocks main brake fluid and allows emergency brake fluid flow during rupture, then emergency braking is enabled, but normal braking function is interrupted
Solution Approach 1:
The alarm provides self-service by automatically alerting the driver when the emergency braking system is activated due to brake fluid leakage. This self-announcement function eliminates the need for complex manual switching mechanisms or additional sensors to detect system mode changes, as the alarm itself serves as the indicator that guides driver operation
Solution Approach 2:
The valve unit dynamically switches between blocking and allowing brake fluid flow based on real-time system conditions. When emergency brake fluid is detected in the brake pipe (indicating rupture and activation of emergency system), the valve unit automatically adjusts its state to block main brake fluid and permit emergency brake fluid flow, enabling adaptive operation without fixed manual configuration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The emergency braking device enables safe braking even when the brake pipe is ruptured by using emergency brake fluid to apply a braking force, preventing safety-related accidents and allowing normal braking to resume when the pipe is intact.
Implementation Method 1
a pressure source connected to the distal end of the piston, and configured to supply high-pressure gas to the piston so that the piston is pressed
Implementation Method 2
an elastic body provided in the valve housing, and configured to return the valve body to its original position
Implementation Method 3
a brake pad (or a brake shoe) configured to be brought into contact with a disk (or a drum) by the pushed piston and generate a braking force
