Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake systems face issues with abnormal release of parking states, leading to vehicle maintenance and towing costs due to sticky forces between brake components, which are difficult to predict and manage.
Innovation Solution
A brake monitoring apparatus and apparatus that includes a controller, monitoring valve, and sensor unit to detect normal or abnormal release of parking states by sensing forces and torques, using compressed air to manage brake operation and generate warnings for abnormal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a brake apparatus continuously provides braking force to prevent vehicle movement in parking state, then vehicle stability is improved, but abnormal release problems occur due to sticky forces between brake components
Solution Approach 1:
The monitoring valve performs preliminary action by detecting potential sticky force conditions before they cause abnormal release. The system monitors brake component states and predicts abnormal release risks, enabling preventive maintenance before actual failures occur.
Solution Approach 2:
The system implements feedback through the monitoring valve that continuously detects brake component states and provides information to the controller. This feedback loop enables real-time monitoring and prediction of abnormal release conditions, allowing the system to respond appropriately based on detected parameters.
2Reliability
If monitoring systems are added to detect abnormal release conditions, then brake system reliability is improved, but device complexity increases
Solution Approach 1:
The monitoring valve serves multiple functions: it monitors brake component states, detects abnormal conditions, and provides predictive information. This multi-functionality reduces the need for separate dedicated sensors and systems, thereby limiting the increase in overall device complexity while maintaining improved reliability.
3Stability of the object's composition
If the parking state is maintained for long periods, then vehicle stability is improved, but sticky forces cause abnormal release and increase maintenance costs
Solution Approach 1:
The system performs preliminary detection of sticky force conditions before they lead to abnormal release during extended parking. By monitoring brake component states in advance, the system enables early intervention and maintenance scheduling, preventing complete brake failure and reducing unexpected maintenance time losses.
Solution Approach 2:
The monitoring system provides continuous feedback on brake component conditions during parking periods, allowing real-time assessment of sticky force development. This feedback enables proactive maintenance decisions based on actual brake state rather than fixed schedules, optimizing maintenance timing and reducing overall maintenance time loss.
