Motorcycle Brake Hydraulic Pressure Control Unit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brake hydraulic pressure control units for motorcycles face challenges in mountability due to strict space restrictions, requiring a large mounting space and complicating the attachment of components, which limits the downsizing of the brake system and increases manufacturing costs.
Innovation Solution
The solution involves separating the inlet valve, outlet valve, and pump in the primary base body and the first and second valves in the secondary base body, allowing for independent downsizing of each base body and reducing the need for extensive channel routing and outer space, thereby improving mountability and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all valves and pump are provided in a single base body, then the brake hydraulic pressure control unit can be integrated, but the mounting space required increases and mountability deteriorates
Solution Approach 1:
The base body is divided into a first base body and a second base body. The first base body accommodates the inlet valve, outlet valve, and pump, while the second base body accommodates the first valve and second valve. This segmentation allows each base body to be optimized independently, reducing the overall mounting space required while maintaining functional integration through hydraulic fluid communication between the two base bodies.
2Ease of manufacture
If a large base body is used to accommodate all components, then all valves and pump can be mounted, but the outer area required increases and attachment becomes more complex
Solution Approach 1:
The components are divided between two separate base bodies based on their functional relationships. The first base body contains the pump and associated valves (inlet valve, outlet valve), while the second base body contains the circuit control valves (first valve, second valve). This segmentation reduces the outer area of each individual base body and simplifies attachment, as each base body can be manufactured and assembled independently before being connected together.
3Area of stationary object
If components are separated into multiple base bodies, then mounting space is reduced and mountability improves, but the number of connections between base bodies increases
Solution Approach 1:
The two base bodies are connected through hydraulic fluid channels that allow brake fluid to flow between them. The inlet valve, outlet valve, and pump in the first base body are hydraulically connected to the first valve and second valve in the second base body through the brake fluid passage system. This hydraulic connection method minimizes the number of physical connections required while maintaining full functional integration between the two base bodies.
