Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake apparatuses face difficulties in maintaining pressure and improving braking efficiency when foreign objects are present, leading to increased maintenance costs, driver anxiety, and potential power waste, while also risking traffic accidents.
Innovation Solution
A pressure control apparatus that includes an input unit for detecting current pressure values, a determination unit to assess if the pressure is at a standard level, and a control unit to adjust the brake system by iterating on/off operations to reach the standard pressure, incorporating components like motors, hydraulic valves, and communication units to manage pressure and communicate with maintenance services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional brake apparatuses operate normally, then braking function is provided, but foreign objects cause difficulty in normal operation and pressure maintenance
Solution Approach 1:
The system performs preliminary diagnosis by detecting pressure values before braking operations to identify foreign objects in advance. The control unit compares detected pressure with standard values and iteratively adjusts pressure to eliminate foreign objects before they interfere with normal braking operations.
Solution Approach 2:
The system continuously monitors pressure values during braking operations and provides feedback to the control unit. When foreign objects are detected through pressure anomalies, the system iteratively adjusts pressure and continues monitoring until the foreign object is eliminated and normal operation is restored.
2Productivity
If foreign objects are removed through iterative on/off operations, then braking efficiency is improved, but additional time and operations are required
Solution Approach 1:
The system performs preliminary pressure adjustment operations during vehicle operation to remove foreign objects before they significantly degrade braking performance. By addressing issues early through iterative on/off operations, the system prevents major efficiency losses that would require more extensive repairs later.
Solution Approach 2:
The brake system performs self-diagnosis and self-correction by automatically detecting pressure anomalies caused by foreign objects and executing iterative on/off operations to remove them. This autonomous maintenance capability eliminates the need for manual intervention and reduces overall system downtime.
3Reliability
If pressure is maintained at standard levels through iterative operations, then braking efficiency improves, but energy consumption increases
Solution Approach 1:
Instead of continuous pressure adjustment, the system employs periodic on/off operations to remove foreign objects and restore pressure to standard levels. The control unit monitors pressure values and triggers iterative operations only when anomalies are detected, rather than continuously adjusting pressure, thereby reducing overall energy consumption.
Solution Approach 2:
The system uses feedback from pressure sensors to determine when iterative operations are necessary. By comparing detected pressure values with standard values and only initiating energy-consuming operations when deviations are detected, the system maintains pressure reliability while minimizing unnecessary energy expenditure.
4Reliability
If diagnostic and control operations are performed continuously, then foreign objects are detected early preventing accidents, but system complexity and maintenance cost increase
Solution Approach 1:
The system uses simple feedback mechanisms where the control unit compares pressure sensor readings with predetermined standard values. When deviations indicate foreign objects, the system triggers iterative on/off operations. This feedback-based approach enables early accident prevention through continuous monitoring without requiring complex diagnostic algorithms or additional hardware.
Solution Approach 2:
The control unit autonomously performs diagnostic functions by monitoring pressure values and automatically initiating iterative operations when foreign objects are detected. This self-service capability eliminates the need for complex external diagnostic systems while maintaining early detection and accident prevention capabilities.
