Annular Filter Device with Rotary Locking Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and replacement of filter devices with annular filter elements are complex due to their integrated design, making them costly and difficult to maintain.
Innovation Solution
A filter device design featuring a detachable closure part that connects the filter element and cover independently, allowing for simplified assembly and maintenance by using a rotary locking mechanism that reduces locking forces and eliminates the need for high-friction sealing, enabling tool-free form-fitting connections and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter element and cover are integrated as a coherent structural unit, then the sealing and structural integrity are improved, but the assembly and disassembly complexity increases
Solution Approach 1:
The filter device is divided into separate components: the filter element, the cover, and a closure part that connects them. This segmentation allows each component to be manufactured and assembled independently, reducing overall assembly complexity while maintaining sealing integrity through the closure part's connecting function
Solution Approach 2:
The closure part acts as an intermediary component between the filter element and the cover. It provides the connecting function that previously required integration, enabling simple assembly and disassembly while ensuring reliable sealing through its intermediate positioning and fastening role
2Stability of the object's composition
If the filter element and cover form a mandatory coherent structural unit, then the structural stability is improved, but the maintenance cost and time increase
Solution Approach 1:
By segmenting the filter device into replaceable components (filter element, cover, closure part), the system allows selective replacement of the filter element without replacing the entire assembly. This maintains structural stability during operation while significantly improving maintenance efficiency
Solution Approach 2:
The filter element can be easily removed and replaced while the cover and closure part remain in place. This enables the expensive cover to be recovered and reused, reducing maintenance costs while maintaining the structural stability of the overall device
3Force
If a rotary locking mechanism is used to connect the closure part, then the locking forces are reduced, but the device complexity increases
Solution Approach 1:
The closure part incorporates a rotary locking mechanism that transitions from a static connection to a dynamic locking process. The rotary movement enables the closure part to lock into position with reduced forces, and the mechanism can be easily reversed for disassembly
Solution Approach 2:
The rotary locking mechanism is designed to be operated manually without external tools or complex actuation systems. The user simply rotates the closure part to lock or unlock, making the system self-servicing and reducing the need for additional complex locking components
