Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust suction devices for disc brakes in vehicles are inefficient in removing particles produced during braking and often suffer from overheating due to high-speed suction fans, which can lead to thermal damage.
Innovation Solution
A brake dust suction device with a suction fan assembly that uses redirected airflow to cool the fan, eliminating the need for additional cooling means and incorporating a filter to collect dust particles, while using guide ribs and air redirection elements to enhance heat dissipation and airflow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If powerful suction fans are used to generate high suction flow, then particle removal efficiency is improved, but fan overheating occurs leading to thermal damage
Solution Approach 1:
The patent redirects the hot exhaust air that would normally be wasted into a cooling flow that actively cools the suction fan. The harmful thermal energy is converted into a beneficial cooling resource, creating a self-sustaining thermal management system without external energy input.
Solution Approach 2:
The system uses its own operational byproduct (hot exhaust air) to cool the fan, making the cooling function self-generated and independent of external power sources or additional cooling systems.
2Object-affected harmful factors
If additional cooling means are installed to cool the suction fan, then thermal damage is prevented, but device complexity and energy consumption increase
Solution Approach 1:
The cooling function is merged with the existing exhaust air flow path. The housing structure integrates both the exhaust outlet and the fan cooling flow path, combining two functions (particle removal and fan cooling) into a unified system design.
Solution Approach 2:
The system uses its own operational byproduct (hot exhaust air) to cool the fan, making the cooling function self-generated and independent of external power sources or additional cooling systems.

4Productivity
If the outlet is positioned away from the fan for optimal particle extraction, then particle removal efficiency is maintained, but fan cooling becomes less effective
Solution Approach 1:
The housing structure acts as an intermediary element that bridges the spatial gap between the exhaust outlet and the fan. It guides and redirects the exhaust air flow through defined pathways to ensure effective cooling of the fan while maintaining optimal outlet positioning for particle extraction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively removes brake dust particles and cools the suction fan without additional energy consumption, preventing thermal damage and maintaining performance over time.
Implementation Method 1
a suction fan assembly (13) comprising a fan (15), a housing (14) and an outlet (17), and configured to suction air comprising brake dust from the disc brake through the opening, the suction line, and the inlet
Implementation Method 2
an air redirection element (21) configured to redirect the air blown out at the outlet (17) of the suction fan assembly to the fan (15) of the suction fan assembly for cooling the fan
Implementation Method 3
Hence, the advantage of the inventive design is that heat generated by the revolution of the suction fan is dissipated into the atmosphere and does not lead to thermally induced damages of the housing
Implementation Method 4
a filter (11, 12) configured to filter the brake dust from the suctioned air
