Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for filling and bleeding brake fluid in vehicle brake systems are labor-intensive, time-consuming, and prone to human error, leading to inefficiencies and safety hazards due to the need for multiple operators to manually press the brake pedal and tighten/loosen bleed screws, which can result in incomplete air evacuation and increased braking response times.
Innovation Solution
An automated system using a hydraulic pump, command sending unit, and wireless transmitter to control the brake fluid pumping and bleed screw operation, integrating the supply of brake fluid, pumping, and screw tightening/loosening through electronic commands and wireless control signals, eliminating the need for manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation method is used for filling and bleeding brake fluid, then multiple operators can perform the task, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical operations with an automated control system. The control unit automatically controls the brake pedal actuator to press the brake pedal and the bleed screw actuator to tighten and loosen the bleed screw, eliminating the need for multiple operators to manually perform these actions. This substitution of mechanical manual operations with automated actuators resolves the contradiction by improving productivity while maintaining ease of operation through centralized control.
Solution Approach 2:
The automated system enables the brake fluid filling and bleeding process to be performed autonomously without requiring multiple operators. The control unit coordinates the actuators to self-manage the entire process, from pressing the brake pedal to tightening and loosening the bleed screw, allowing the system to serve itself and eliminating labor-intensive manual operations.
2Reliability
If manual operation is used to tighten and loosen bleed screw, then human error may occur, but automation increases device complexity
Solution Approach 1:
The patent replaces manual mechanical operations with an automated control system. The control unit automatically controls the brake pedal actuator to press the brake pedal and the bleed screw actuator to tighten and loosen the bleed screw, eliminating the need for multiple operators to manually perform these actions. This substitution of mechanical manual operations with automated actuators resolves the contradiction by improving productivity while maintaining ease of operation through centralized control.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors the bleeding process and adjusts the actuator operations accordingly. This feedback control ensures that the bleed screw is tightened and loosened at the correct times and with the correct forces, eliminating human error while managing device complexity through intelligent control algorithms.
3Ease of operation
If automated control system is implemented, then labor cost is reduced, but the system complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the brake pedal actuator, the bleed screw actuator, and coordinates the entire filling and bleeding process. This multi-functionality allows a single centralized control system to manage all operations, reducing the need for multiple separate systems and operators, thereby improving ease of operation while managing overall system complexity through functional integration.
