Motorcycle Brake Pressure Control Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake hydraulic pressure control devices for motorcycles are costly and difficult to manufacture due to space constraints and complex pipe layouts in the trunk portion, affecting design flexibility and performance.
Innovation Solution
A brake hydraulic pressure control device with a base body fixed below the spring at the connecting portion between the trunk and wheel, reducing the need for layout changes and complex pipe arrangements, and enhancing cost and manufacturing performance by positioning the base body outside the trunk portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base body is mounted on the trunk portion, then the brake hydraulic pressure control device can be integrated into the brake system, but the layout of trunk portion parts must be changed and complex pipe arrangements are required
Solution Approach 1:
The base body is extracted from the trunk portion and relocated to the connecting portion between the trunk and wheel. This extraction eliminates the need for complex pipe arrangements within the trunk and avoids layout changes, while still achieving functional integration of the brake hydraulic pressure control device into the overall brake system.
2Adaptability or versatility
If the base body is mounted on the trunk portion, then the brake system can be integrated, but cost performance and manufacturing performance decrease
Solution Approach 1:
The base body is extracted from the trunk portion assembly and repositioned to the connecting portion. This simplifies the manufacturing process by eliminating the need for complex integration work in the trunk area, reduces assembly complexity, and improves cost performance while maintaining brake system functionality.
Solution Approach 2:
Instead of integrating the base body into the trunk portion as conventionally done, the invention inverts the mounting approach by placing it at the connecting portion. This reverse mounting strategy simplifies both manufacturing and assembly processes, improving ease of manufacture and cost performance.
3Adaptability or versatility
If the base body is mounted on other portions, then design flexibility may be maintained, but design performance may be lowered
Solution Approach 1:
The connecting portion serves as an intermediary location between the trunk portion and the wheel. By mounting the base body at this intermediate position, the invention maintains design flexibility while avoiding the pitfalls of both trunk portion mounting (complex pipes) and arbitrary location mounting (potential performance issues). The connecting portion acts as an optimal mediator that satisfies both design flexibility and performance requirements.

AI summary
A brake hydraulic pressure control device (2) controls a fluid pressure of a brake fluid supplied to wheel cylinders mounted on brake calipers (107, 114) of a motorcycle (100). The brake hydraulic pressure control device (2) includes: a base body in which flow passages are formed; and valves which open or close the flow passages. The base body is fixed below a spring in connecting portions (130A, 130B) which connect a trunk portion (101) of the motorcycle (100) and a wheels (front wheel (106), rear wheel (113)) to each other.
