Pressure Medium Assembly Housing Flange Radial Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pressure medium assemblies for braking systems have limited printed circuit board space due to the dimensions of the flanges, leading to increased production costs and complexity in assembly, as well as potential mechanical tensions and safety issues.
Innovation Solution
The pressure medium assembly features a housing flange that projects radially outward from the housing block, allowing the control unit to be fastened from the drive motor side, enabling larger printed circuit boards and reducing the need for recesses, with self-tapping fasteners and modular attachment options for flexible integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flanges are made large enough to allow machine assembly and sealing, then reliability of connection is improved, but printed circuit board area is reduced
Solution Approach 1:
The patent moves the fastening operation from the traditional flange region (circumferential side) to the end face region of the housing block. This dimensional shift allows the printed circuit board to occupy the entire circumferential surface without recesses, while fastening elements are introduced through threaded holes in the end face, resolving the area conflict between connection reliability and board space.
Solution Approach 2:
The patent separates the fastening function from the flange structure by providing threaded holes directly in the housing block end face. This segmentation allows the printed circuit board to be a simple rectangular shape without cutouts, while connection reliability is maintained through dedicated threaded fastening points independent of the board layout.
2Ease of operation
If recesses are added to the printed circuit board for flange access, then connection accessibility is improved, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of modifying the printed circuit board to accommodate fastening operations (adding recesses), the patent inverts the approach by providing threaded holes directly in the housing block. This allows fastening elements to be introduced from the end face side, eliminating the need for board recesses and simplifying board manufacturing while maintaining fastening accessibility.
3Area of stationary object
If printed circuit board area is increased, then electronic component capacity is improved, but risk of mechanical damage during assembly increases
Solution Approach 1:
The patent extracts the fastening operation from the printed circuit board region and relocates it to the housing block end face. Threaded holes are provided in the end face to receive fastening elements, completely separating the fastening function from the board assembly area. This allows large rectangular boards to be installed without mechanical risks, as fastening occurs independently at the housing block.
4Area of stationary object
If flange dimensions are reduced to maximize board area, then printed circuit board area is improved, but machine assembly capability deteriorates
Solution Approach 1:
The patent relocates the fastening operation from the circumferential flange region to the end face region of the housing block. This dimensional change allows the printed circuit board to extend to the full circumferential surface, while machine assembly is enabled through threaded holes in the end face that accommodate automated fastening elements, preserving both board area and assembly capability.

AI summary
A pressure medium assembly, in particular for providing and regulating a pressure in a brake circuit of a slip-controllable brake system of a motor vehicle, includes a housing block and an electronic controller. The housing block includes a pump configured to be actuated by a drive motor and a valve, which are actuated by the controller. The controller is secured to an outer face of the housing block and has a device flange that is paired with a housing flange formed on the housing block. The flanges fix the housing block and the controller together. The housing flange protrudes radially outwards relative to a housing block peripheral side facing the housing flange such that the entire upper face of the housing block is available for a controller housing. This configuration additionally allows the use of a printed circuit board which is free of open recesses on the peripheral side.
