Solution Overview
Problem
Existing wheel braking controllers for vehicles have a high number of parts and complex mounting requirements, leading to increased weight, complexity, and mounting time, as well as inefficiencies in air release and maintenance.
Innovation Solution
The integration of a channel switching unit and hydraulic pressure generator on a single body with shared mounting members, housing the actuator within the channel switching unit, and orienting electromagnetic valves for improved air release and maintainability, while concentrating channels on one surface for easier processing and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the channel switching unit and hydraulic pressure generator are mounted separately on the vehicle body, then each unit can be independently maintained and replaced, but the number of mounting members increases and the mounting process becomes more complex
Solution Approach 1:
The patent combines the channel switching unit and hydraulic pressure generator into a single integrated mounting structure. The channel switching unit is mounted on the hydraulic pressure generator using mounting members, eliminating the need for separate mounting brackets and fasteners for each unit. This integration reduces the total number of mounting members while maintaining the functional independence of both units for maintenance purposes.
2Reliability
If multiple separate mounting members are used for the channel switching unit and hydraulic pressure generator, then each unit can be securely fixed, but the weight of the vehicle increases
Solution Approach 1:
The patent reduces vehicle weight by integrating the mounting structure. Instead of using separate mounting members for both units, the channel switching unit is mounted directly on the hydraulic pressure generator, which itself is mounted on the vehicle body. This shared mounting approach reduces the number of mounting members and consequently reduces the overall weight while maintaining secure fixation of both units.
3Ease of manufacture
If the channel switching unit and hydraulic pressure generator are mounted separately, then installation is straightforward, but the mounting man-hours increase
Solution Approach 1:
The patent reduces mounting man-hours by combining the mounting operations. The hydraulic pressure generator is first mounted on the vehicle body using mounting members, and then the channel switching unit is mounted on the already-installed hydraulic pressure generator. This sequential mounting approach reduces the total number of mounting operations and fastening steps compared to mounting both units separately on the vehicle body, thereby reducing installation time and labor requirements.
4Adaptability or versatility
If connecting members such as hoses are used to connect the channel switching unit and hydraulic pressure generator, then flexible installation is possible, but the system complexity and part count increase
Solution Approach 1:
The patent eliminates the need for connecting hoses between the channel switching unit and hydraulic pressure generator by integrating them into a single mounting assembly. The brake fluid channels are formed within the integrated structure, with the channel switching unit's channels connecting directly to the hydraulic pressure generator's internal passages. This integration removes the external hose connections while maintaining fluid communication, thereby reducing system complexity and part count while preserving installation flexibility through the modular mounting design.

AI summary
A wheel braking controller of a vehicle includes a brake lever operated by a rider, a master cylinder generating a hydraulic pressure according to an operation force of the brake lever, and a brake caliper braking a front wheel based on operation of the brake lever, a channel switching unit provided between the master cylinder and the brake caliper and switching channels of a brake fluid. A hydraulic pressure generator generates a hydraulic pressure based on operation of the brake lever and the driving state of the vehicle and controlling braking of the front wheel using the brake caliper by the hydraulic pressure. A braking controller including the channel switching unit and the hydraulic pressure generator is integrally provided on one body. The wheel braking controller so configured reduces the number of parts, and provides for easy mounting of the controller on the vehicle body.
