Dust Suction Device with Supporting Ring for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust suction devices face issues with structural instability during storage, leading to components being exposed and the quick-installation structure bearing excessive weight, which can cause collisions and incomplete accommodation.
Innovation Solution
A dust suction device design featuring a supporting ring and dust suction assembly that allows for complete storage within a dust collection barrel, utilizing connectors and connecting structures to stabilize the assembly and reduce volume during non-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the head housing is suspended on the opening of the dust collection barrel during storage, then the dust suction device can be compacted, but the quick-installation structure bears excessive weight causing structural instability
Solution Approach 1:
The invention divides the storage support function into two separate components: the quick-installation structure (for connection only) and the supporting ring (for weight bearing). This segmentation allows the quick-installation structure to avoid bearing excessive weight while the supporting ring provides dedicated support, resolving the contradiction between compact storage and structural stability.
Solution Approach 2:
The supporting ring acts as an intermediary component between the dust collection barrel and the head housing during storage. It transfers the weight of the head housing from the quick-installation structure to the dust collection barrel, enabling compact storage without overloading the quick-installation structure.
2Volume of moving object
If the head housing is suspended on the opening of the dust collection barrel during storage, then the device can be compacted, but components may collide with the filter element due to insufficient structural stability
Solution Approach 1:
By separating the support function from the connection function, the invention ensures that the head housing is stably supported during storage, preventing collisions with the filter element while maintaining compact storage volume.
Solution Approach 2:
The supporting ring provides beforehand support for the head housing during storage, preventing potential collisions with the filter element before they can occur. This prior cushioning ensures reliable storage without compromising compactness.
3Volume of moving object
If the head housing is suspended upside down during storage, then the device can be compacted, but the head housing cannot be completely accommodated in the dust collection barrel
Solution Approach 1:
Instead of suspending the head housing upside down, the invention inverts the approach by placing the head housing right-side up on the supporting ring. This allows the head housing to be completely accommodated within the dust collection barrel while maintaining compact storage volume.
4Volume of moving object
If the quick-installation structure bears the weight of the head housing during storage, then the device can be compacted, but the quick-installation structure may fail due to excessive weight
Solution Approach 1:
The invention divides the load-bearing function from the connection function, assigning weight support to the supporting ring and connection to the quick-installation structure. This protects the quick-installation structure from excessive weight while enabling compact storage.
Solution Approach 2:
The supporting ring serves as an intermediary that bears the weight of the head housing during storage, preventing this load from being transferred to the quick-installation structure and causing structural failure.
