Wireless Filter Apparatus for Motor Vehicle Air Pre-Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle ventilation systems face a compromise between fine-dust filtration and pressure loss, and existing air filtration systems cannot effectively clean the air independently of the ventilation system, especially when the blower is deactivated.
Innovation Solution
A remote-controlled filter apparatus that operates independently of the ventilation system, using a wireless signal to activate a delivery device and filter element to clean the air in the passenger compartment, allowing for pre-conditioning of the air before the vehicle is started and providing an additional, efficient air cleaning solution without the need for the blower to be operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ventilation system with blower is used for air filtration, then air can be filtered through the filter element, but the system cannot operate when the blower is deactivated and creates higher noise and energy consumption
Solution Approach 1:
The patent segments the air filtration function from the ventilation system by introducing a separate delivery device that can operate independently. The delivery device is a distinct component with its own motor, allowing it to function separately from the blower-driven ventilation system, thereby enabling air filtration even when the ventilation system is deactivated.
Solution Approach 2:
The delivery device is designed to perform the air filtration function autonomously without requiring the ventilation system to be active. It serves itself by having an independent power source and control mechanism, allowing it to operate on its own to draw in and deliver air through the filter element whenever needed, regardless of the ventilation system state.
2Reliability
If fine-dust filtration is implemented in the ventilation system, then air quality improves, but pressure loss increases
Solution Approach 1:
The patent extracts the fine-dust filtration function from the ventilation system and places it in a dedicated filter apparatus with its own delivery device. This separation allows the filter element to be optimized for fine-dust filtration without being constrained by the ventilation system's pressure loss characteristics, as the delivery device can be specifically designed to match the filter element's requirements.
Solution Approach 2:
The delivery device enables parameter changes in the air flow to optimize filtration performance. By independently controlling the delivery device's motor speed and airflow parameters, the system can adjust operating conditions to achieve effective fine-dust filtration while minimizing pressure loss, separate from the ventilation system's fixed operating parameters.
3Reliability
If the ventilation system is used for air cleaning, then air can be filtered, but the system cannot pre-condition air before the vehicle is started
Solution Approach 1:
The delivery device enables preliminary action by allowing air filtration to occur before the vehicle is started or the ventilation system is activated. The independent delivery device can be activated in advance to pre-condition the air in the passenger compartment, removing noxious substances and improving air quality before occupants enter or before the main system begins operation.
4Ease of operation
If the delivery device operates independently of the ventilation system, then air can be filtered when the blower is deactivated, but the device complexity increases
Solution Approach 1:
The patent merges the air intake and delivery functions into a single integrated delivery device, while keeping the filter element as a shared component between the ventilation system and the delivery device. This combining approach reduces overall system complexity by eliminating redundant components and utilizing the existing filter element, thereby achieving independent operation without proportionally increasing device complexity.
