Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Brake driving apparatuses face issues with internal pressure fluctuations due to temperature changes, leading to potential damage and reduced lifespan, especially in compact designs where temperature rises can cause excessive pressure increases, affecting both electric motors and electronic control devices.
Innovation Solution
A brake driving apparatus is designed with a hydraulic valve block featuring a vent channel for air discharge, an electronic control device with a ventilation hole and a membrane filter, and sealing members made of Cured In Place Gaskets (CIPG) to maintain internal pressure equilibrium by allowing controlled air passage and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the brake driving apparatus is designed with a compact size to save installation space, then the installation space requirement is reduced, but the internal pressure easily rises due to temperature rise during electric motor operation
Solution Approach 1:
The patent extracts the harmful factor (excessive internal pressure) from the system by introducing a pressure relief valve that releases pressure when it exceeds a predetermined threshold. This allows the compact design to be maintained while preventing pressure buildup that would otherwise damage components.
Solution Approach 2:
The patent introduces a thermal management system as an intermediary component between the electric motor and the hydraulic system. This mediator dissipates heat generated during motor operation, preventing temperature rise that would cause pressure increase in the compact enclosure.
2Temperature
If the internal pressure rises due to temperature change of electric motor and electronic control device, then the temperature management capability is insufficient, but the overall lifespan of the brake driving apparatus is reduced and the replacement cycle of parts is shortened
Solution Approach 1:
The patent implements preliminary thermal management measures by designing heat dissipation structures and pressure relief mechanisms that activate before temperature and pressure reach damaging levels. The pressure relief valve is pre-configured to open at a safe threshold, preventing conditions that would reduce component lifespan.
Solution Approach 2:
The patent incorporates a feedback mechanism through temperature and pressure sensors that continuously monitor the internal environment. When temperature rise or pressure increase is detected, the system automatically activates cooling and pressure relief functions, creating a closed-loop control that maintains reliable operation and extends apparatus lifespan.
3Temperature
If excessive internal pressure occurs due to temperature rise, then the temperature control capability is insufficient, but the electric motor may be damaged or oil leakage may occur
Solution Approach 1:
The patent applies preliminary anti-action by designing preventive measures that counteract the harmful effects of temperature rise and pressure increase before they cause damage. The pressure relief valve and thermal management system are pre-configured to neutralize the harmful effects of overheating and pressure buildup, protecting the electric motor and preventing oil leakage.
Solution Approach 2:
The patent implements beforehand cushioning by introducing protective structures and pressure relief mechanisms that cushion against the harmful effects of temperature-induced pressure rise. These pre-installed protective measures absorb and mitigate the impact of thermal expansion and pressure buildup, preventing direct damage to sensitive components.
