Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current brake control systems lack efficient diagnostic tools for maintenance issues, particularly in accessing and adjusting wheel braking force in response to driving conditions, which can lead to suboptimal braking performance and safety concerns.
Innovation Solution
An ABS diagnostic tool that electrically connects to the anti-skid braking system, providing access through a breakout circuit with terminal sets for tools like multi-meters to diagnose maintenance issues, allowing for real-time adjustments of hydraulic fluid pressure based on wheel speed feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brake control systems are used without specialized diagnostic tools, then the system structure remains simple, but diagnostic capability and maintenance efficiency are insufficient
Solution Approach 1:
The patent introduces a diagnostic tool as an intermediary device that connects to the brake control system through existing electrical connections. This mediator provides comprehensive diagnostic capabilities including voltage measurement, resistance measurement, and circuit testing without requiring modifications to the brake control system itself, thus resolving the contradiction between enhanced diagnostic capability and system structure simplicity
Solution Approach 2:
The diagnostic tool integrates multiple diagnostic functions (voltage measurement, resistance measurement, circuit continuity testing, component testing) into a single universal device. This multi-functional approach enables comprehensive system diagnostics through one tool rather than requiring multiple separate instruments, improving reliability while maintaining reasonable system complexity
2Ease of operation
If electrical connections are made directly to ABS components, then diagnostic access is achieved, but safety risks and potential damage to sensitive electronics increase
Solution Approach 1:
The diagnostic tool serves as a safe intermediary that interfaces with the ABS system through predetermined electrical connection points. It provides galvanic isolation and controlled signal injection, allowing diagnostic measurements and adjustments without direct exposure of sensitive ABS electronics to external diagnostic equipment, thus enabling easy access while minimizing safety risks
Solution Approach 2:
The system incorporates protective measures beforehand by designing the diagnostic interface with built-in protection circuits that prevent voltage spikes, current overloads, and static discharge from damaging ABS components. This prior cushioning approach allows straightforward diagnostic access while pre-emptively guarding against harmful effects
