Master Cylinder Mounting Fixture for Crowded Engine Bay Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The crowded engine compartment of vehicles makes it difficult to position and secure the master cylinder assembly for connection to the brake pedal, as existing methods require manual positioning and securing, which can be challenging due to the tight space and risk of movement during attachment.
Innovation Solution
A mounting fixture with a base and anchor portion secured to the wheel well, featuring a cylinder assembly engagement member that contacts the master cylinder assembly to hold it firmly against a firewall, allowing for secure positioning and connection to the brake pedal without manual adjustment during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual positioning and securing methods are used to hold the master cylinder assembly, then the assembly can be connected to the brake pedal, but the crowded engine compartment makes it difficult to position and secure the assembly without movement during attachment
Solution Approach 1:
The mounting fixture is pre-configured with an anchor portion that engages with the wheel well structure before the master cylinder assembly is positioned. The base is designed to contact the firewall and the engagement member is positioned to contact the master cylinder assembly, all in advance, so that when the assembly is placed, it is immediately secured in the correct position without requiring manual adjustment or holding during attachment
Solution Approach 2:
The mounting fixture serves as an intermediary device between the wheel well structure and the master cylinder assembly. It includes an anchor portion that secures to the wheel well, a base that provides a mounting surface, and an engagement member that contacts the master cylinder assembly. This intermediary fixture transfers and maintains the positional relationship between the wheel well and the master cylinder assembly, enabling reliable connection to the brake pedal
2Ease of manufacture
If the engine compartment is accessed for master cylinder assembly connection, then the brake pedal can be connected to the cylinder assembly, but the crowded space with other vehicle components creates difficulty in positioning and applying securing mechanisms
Solution Approach 1:
The mounting fixture is divided into distinct functional segments: an anchor portion for securing to the wheel well, a base for providing a stable mounting surface against the firewall, and an engagement member for contacting and positioning the master cylinder assembly. This segmentation allows each component to be optimized for its specific function and enables the fixture to be installed in the limited space of the engine compartment without requiring complex integrated mechanisms
Solution Approach 2:
The mounting fixture acts as an intermediary tool that bridges the gap between the fixed wheel well structure and the master cylinder assembly that needs to be positioned. By securing the anchor portion to the wheel well first, the fixture creates a stable reference point that allows the engagement member to accurately position the master cylinder assembly against the firewall, making the assembly operation feasible in the crowded engine compartment

AI summary
A mounting fixture for holding a braking system master cylinder against a mounting element in a vehicle engine compartment includes a base and an anchor portion secured to the base and structured to secure a portion of the mounting fixture to a wheel well in the engine compartment. A cylinder assembly engagement member is secured to the base opposite the anchor portion. In some arrangements, the mounting element may be a firewall of the engine compartment. Use of the fixture to hold the cylinder in position with respect to the mounting element enables a user to operatively connect a brake pedal to the cylinder without the need to manually secure the cylinder in position during connection.
