Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices are limited by the effective collection area and require increased suction power or surface contact to detach particles, which can prolong scanning times for large areas.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional suction devices increase suction power by improving pump power or contacting surface with brushes, then particle detachment is improved, but device complexity and energy consumption increase
Solution Approach 1:
The suction head is segmented into multiple independent airflow paths with separate outlets (radial outlets and forward outlets) that can be controlled independently. This allows the system to use different airflow patterns for different detachment needs without requiring a single high-power pump to handle all scenarios, thus improving particle collection efficiency while managing energy consumption.
Solution Approach 2:
The system dynamically switches between different airflow configurations (radial airflow mode, forward airflow mode, or combined mode) based on the specific detection needs and particle adhesion conditions. This dynamic adaptability allows the device to optimize energy usage by applying the appropriate airflow pattern rather than continuously operating at maximum power.
2Productivity
If conventional suction devices increase suction power to detach particles, then particle detachment is improved, but the effective collection area remains limited by head size
Solution Approach 1:
The invention transitions from a single-direction suction approach to a multi-dimensional airflow system with radial outlets providing airflow in multiple directions simultaneously. This dimensional expansion of airflow patterns allows the limited head size to effectively cover and detach particles from a larger surface area, overcoming the geometric limitation of the suction head footprint.
3Area of stationary object
If conventional suction devices wave over large areas to detect explosive material, then detection coverage is improved, but scanning time increases
Solution Approach 1:
The system maintains continuous particle detachment and collection action through its multi-outlet configuration that can operate simultaneously in different directions. This continuous multi-directional airflow eliminates the need to reposition or re-scan areas, allowing the device to cover large detection areas efficiently without time loss from repeated scanning of the same regions.
4Quantity of substance
If conventional suction devices contact surface with vacuum head to collect particles, then particle collection is improved, but the spot of particle collection is limited to head size
Solution Approach 1:
The suction head is segmented into multiple independent airflow paths with separate outlets (radial outlets and forward outlets) that can be controlled independently. This segmentation allows the system to project airflow in multiple directions simultaneously, effectively expanding the collection spot size beyond the physical head dimensions while maintaining controlled particle collection.
