Modular Fresh Air Filtration for Road Machine Control Consoles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road making machines face challenges in maintaining air quality for operators due to fumes from asphalt laying and material bunkers, leading to high construction and manufacturing costs for integrated suction/blower systems, which are not universally applicable across different machine types.
Innovation Solution
A modular fresh air device with a blower unit, filter unit, and air discharge unit that can be removably attached to driver control panels or external control consoles, providing a standardized, off-grid air purification solution that can be adjusted and controlled independently of the machine's components, reducing manufacturing costs and increasing applicability across various machine types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If integrated suction/blower systems are used to improve air quality, then air purification effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The fresh air means is designed as a separable attachment device that can be independently mounted on the control platform, rather than being integrated into the machine structure. This segmentation allows the air purification function to be added without complicating the overall machine system architecture.
Solution Approach 2:
The fresh air means is designed as a universal attachment that can be used across different machine types and series. The standardized design with adaptable mounting options enables one device to serve multiple machine configurations, reducing the need for machine-specific customizations.
2Object-affected harmful factors
If integrated suction/blower systems are designed for different machine types, then air quality is improved, but manufacturing cost increases
Solution Approach 1:
The fresh air means employs a universal design that can be attached to various control platforms across different machine types. This standardization enables bulk production and reduces per-unit manufacturing costs compared to custom-integrated systems for each machine variant.
Solution Approach 2:
The attachment device is designed as a standalone, relatively simple unit that can be produced cost-effectively. The modular design with standard components allows for economical manufacturing and potential replacement without affecting the main machine system.
3Object-affected harmful factors
If suction means are positioned to cover auger space, then fumes are sucked off effectively, but coverage extends to material bunker region causing increased complexity
Solution Approach 1:
The fresh air means extracts and addresses the specific air quality problem at the control platform location independently, rather than attempting to solve all fume issues across the entire machine with a single integrated system. This focused approach simplifies the overall system configuration.
