Brake Fluid Reservoir Valve Layout for Contamination-Free Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake fluid reservoirs for racing motorcycles are prone to contamination during bleeding and topping up operations, leading to potential braking system failures due to the introduction of impurities and difficulty in air escape, with filters complicating these operations and requiring frequent maintenance.
Innovation Solution
A brake fluid reservoir design featuring an auxiliary opening with a valve to regulate fluid flow, allowing controlled filling and bleeding without exposing the fluid to external contaminants, and incorporating a filter in a delivery conduit to minimize contamination while facilitating operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is positioned inside the brake fluid receptacle to prevent impurities from circulating, then the braking system is protected from impurities, but bleeding operations become difficult and air escape is hindered
Solution Approach 1:
The filter is segmented from the receptacle and placed in the delivery conduit instead. This separation allows the filter to protect the system from impurities while not interfering with bleeding operations in the receptacle, as the filter is positioned downstream in the fluid delivery path.
Solution Approach 2:
The delivery conduit acts as an intermediary element that carries the filter between the receptacle and the braking system. This intermediary positioning allows the filter to perform its protective function without being directly in the receptacle where it would obstruct bleeding operations.
2Ease of operation
If the brake fluid reservoir is opened for bleeding and topping up during test sessions, then the braking system can be maintained, but impurities and dirt enter the brake fluid
Solution Approach 1:
The filter is pre-positioned in the delivery conduit to establish a protective barrier before any maintenance operations begin. This preliminary protective measure ensures that even when the receptacle is opened for bleeding or topping up, impurities cannot enter the brake fluid through the open receptacle opening.
Solution Approach 2:
The filter in the delivery conduit serves as an intermediary protective element that mediates between the external environment and the brake fluid. It allows maintenance operations to proceed while blocking impurities from entering the fluid path.
3Reliability
If a filter is installed in the brake fluid receptacle, then impurities are filtered from the brake fluid, but the filter progressively clogs requiring periodic inspection or replacement
Solution Approach 1:
The filter is extracted from the receptacle and repositioned in the delivery conduit. This extraction removes the filter from the confined space of the receptacle, making it more accessible for maintenance while still maintaining its filtration function in the fluid delivery path.
Solution Approach 2:
By positioning the filter in the delivery conduit as an intermediary element, it becomes more accessible for inspection and replacement while continuing to perform its filtration function. The intermediary location allows easier maintenance compared to being embedded in the receptacle.
