Solution Overview

Problem

Existing filter systems for brake dust particles in vehicles operate indiscriminately, leading to reduced effectiveness in polluted environments and shortened lifespan due to continuous suction, which is not optimized for varying road and environmental conditions.

Innovation Solution

A filter system that includes a processor to determine operation states based on environmental and driving mode data, controlling the suction device to enable or disable the active brake dust particle filter in real-time, optimizing its use according to weather, pollution levels, and driving conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the suction device operates continuously to filter brake dust particles, then the filtering effectiveness is maintained, but the filter element loads faster and lifespan is reduced

Engineering Contradiction:
Improvefiltering effectivenessVSAvoidfilter element lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The suction device transitions from static continuous operation to dynamic conditional operation, adjusting its state based on real-time environmental data and driving mode detection. The processor enables or disables the suction device dynamically, optimizing both filtering effectiveness and filter element lifespan.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback control by continuously monitoring environmental conditions and driving modes, then adjusting the suction device operation accordingly. The processor receives data about pollution levels and braking events, and uses this feedback to determine when activation is necessary, preventing unnecessary filter loading.

Inventive Principle:
Principle #23Feedback

2Reliability

If the suction device is activated in highly polluted environments, then brake dust filtration is attempted, but the filter element loads faster than usual

Engineering Contradiction:
Improvebrake dust filtrationVSAvoidfilter element load
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The processor monitors environmental pollution levels and compares them against thresholds. When external pollution is high, the system detects this through sensors and feedback mechanisms, then disables the suction device to prevent the filter from loading with excessive environmental particulates, not just brake dust.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the operational parameter of the suction device from 'always on' to 'conditionally on' based on environmental parameters. The processor adjusts the activation state according to measured pollution levels, driving mode, and braking event frequency, optimizing the balance between filtration need and filter protection.

Inventive Principle:
