Hydraulic Valve Block Venting for Brake Motor Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In brake driving devices with compact installation spaces, the increase in internal motor pressure leads to motor damage, shortening the lifespan and requiring frequent replacements, which increases time and cost.
Innovation Solution
A hydraulic valve block with a vent channel and vent holes that communicate the motor unit's pressure rise to the outside, maintaining pressure equilibrium by discharging pressure and heat through first and second vent holes, with the first hole positioned above the block through-hole to prevent oil accumulation and the second hole communicating with the electronic control unit for filtered air intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the brake driving device uses a compact installation space design, then the device size is reduced, but the internal motor pressure increases causing motor damage
Solution Approach 1:
The patent extracts the harmful pressure accumulation from the motor unit by introducing a vent channel that communicates the internal motor space with the external environment. This allows pressure to be released externally, preventing motor damage while maintaining the compact device design.
Solution Approach 2:
The vent channel acts as an intermediary pathway between the motor unit interior and exterior, enabling pressure equilibrium without requiring changes to the motor itself or the overall compact structure of the device.
2Stability of the object's composition
If the motor operates in a compact space, then the device maintains compact dimensions, but pressure builds up inside the motor causing damage
Solution Approach 1:
The harmful internal pressure is extracted from the motor unit through the vent channel, which provides a direct communication path to the external environment, thereby maintaining pressure equilibrium and preventing motor damage.
3Reliability
If vent holes are positioned to discharge pressure, then pressure equilibrium is maintained, but oil may accumulate and cause contamination
Solution Approach 1:
The patent applies different functional qualities to different vent holes: the first vent hole (higher position) primarily discharges pressure and heat, while the second vent hole (lower position) handles oil discharge and contamination control. This local differentiation optimizes both pressure control and contamination prevention.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning vent holes at different heights within the motor unit. The higher first vent hole discharges pressure and heat, while the lower second vent hole manages oil discharge, creating a gravity-assisted separation that prevents oil accumulation and contamination.
