Modular Blower Attachment for Road Paver Fume Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road making machines require high construction efforts and varied designs for suction systems to manage fumes, leading to increased manufacturing costs and limited applicability across different machine types.
Innovation Solution
A modular blower means with a centrifugal fan and air discharge unit, designed as an off-grid attachment module that can be easily mounted and adjusted on various road making machines, forming an air barrier to protect operators from fumes, and can be operated independently of the machine's blower and suction components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional suction systems are used for each machine type, then fume removal effectiveness is maintained, but manufacturing costs increase and construction effort rises
Solution Approach 1:
The patent applies universality by designing a standardized blower attachment that can be used across multiple road making machine types (pavers, chargers, recyclers). This single universal design replaces the need for custom suction systems for each machine type, reducing manufacturing costs while maintaining fume protection effectiveness through consistent air barrier performance
2Adaptability or versatility
If custom suction systems are designed for each machine type, then specific fume protection needs are met, but device complexity increases
Solution Approach 1:
The patent applies segmentation by separating the blower attachment as an independent, removable module that can be attached to or removed from different machine types. This modular approach allows the same standardized component to serve multiple machine types without requiring complex custom integration, reducing device complexity while maintaining adaptability
Solution Approach 2:
The standardized blower attachment serves as a universal solution that can be applied to pavers, chargers, and recyclers, eliminating the need for machine-type-specific designs and thereby reducing overall system complexity across the product line
3Ease of operation
If integrated blower and suction components are used, then fume management is achieved, but ease of operation and on-site adjustment are reduced
Solution Approach 1:
The patent applies dynamics by making the blower attachment removable and adjustable on-site. Operators can easily attach, detach, and reposition the air barrier unit as needed based on operational conditions, allowing flexible adaptation to different fume generation scenarios without being constrained by fixed integrated systems
4Reliability
If multiple special manufactures are developed, then specific machine requirements are met, but manufacturing costs increase
Solution Approach 1:
The patent eliminates the need for multiple special manufactures by creating a single universal blower attachment design that reliably protects operators across all road making machine types. This standardization maintains fume protection effectiveness while significantly reducing manufacturing costs through economies of scale and simplified production
