Stationary suction unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stationary suction units for industrial dirt collection require heavy dirt collection containers to be manually moved and emptied, posing handling difficulties due to their weight and the need for significant operator effort.
Innovation Solution
A lightweight stationary suction unit is designed to move towards and away from the dirt collection container, allowing the container to be easily pushed on the ground without lifting, featuring a self-supporting housing, adjustable connection unit, and a deflection gear for effortless positioning changes, along with a coupling device for the filter assembly to facilitate easy maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dirt collection container is made heavy-duty to handle significant amounts of dirt, then the container's durability and capacity are improved, but the handling difficulty increases due to weight
Solution Approach 1:
The system is divided into two separate components: a stationary suction unit that remains fixed and a movable dirt collection container. This segmentation allows the container to be lightweight and easy to move while the suction unit provides the structural stability needed for heavy-duty operation. The container can be easily detached and repositioned without moving the entire suction system.
Solution Approach 2:
A connection unit with deflection gear acts as an intermediary mechanism between the stationary suction unit and the movable dirt collection container. This intermediary allows for easy coupling and decoupling of the container, enabling operators to quickly remove and reposition the container without manual lifting or complex fastening operations.
2Reliability
If the suction unit is made stationary and heavy to provide stable suction, then the suction stability is improved, but the ease of moving the unit for maintenance and container exchange deteriorates
Solution Approach 1:
The system separates the stationary suction unit from the movable dirt collection container. The suction unit remains fixed and heavy to maintain stable suction performance, while only the lighter container needs to be moved for maintenance or when full. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
The connection unit incorporates a deflection gear that allows dynamic adjustment between different positions. The connection unit can be easily moved between a first position (for container attachment) and a second position (for container removal), providing operational flexibility without requiring the entire suction unit to be moved.
3Ease of operation
If the connection unit is made adjustable to facilitate easy container exchange, then the ease of operation is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The connection unit employs a deflection gear mechanism that provides dynamic positioning capability. This mechanism allows the connection unit to be easily adjusted between a first position (for container attachment) and a second position (for container removal) through simple manual operation, achieving ease of container exchange without requiring complex automated systems.
Solution Approach 2:
The deflection gear is designed to be manually operable by the user without requiring external power sources or complex control systems. The mechanism self-adjusts through direct user input, allowing easy position changes for container exchange while minimizing the overall system complexity.

AI summary
The suction unit (10) has a connection unit (28) that is flow-connected between a sow aggregate and a dirt collection container (40). The connection unit is flow-connected with sow aggregate suction terminal, such that the suction terminal is adjusted and flow-connected to the dirt collection container in an operational position (B). The suction terminal is moved away and fluidly separated from the dirt collection container, during alternate position (W). A support portion is moved away, so that the dirt collection container is released during alternate position of connection unit.
