Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner filter bag closure devices are complex and error-prone due to the use of additional spring elements, requiring intricate adjustments and assembly processes, which complicates manufacturing and increases costs.
Innovation Solution
A device featuring a holding device and closure device where the closure device utilizes a crosslinked silicone elastomer as an elastic element to bias a closure flap, eliminating the need for additional springs and providing both restoring force and hinge function, allowing for a simpler and cost-effective production process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spring elements are used in closure devices, then the closure function is achieved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the spring element and closure flap into a single integrated component made of elastomeric material. The closure flap itself is formed from the elastomeric material with an integrated spring element, eliminating the need for separate spring components and reducing assembly steps while maintaining the closure function.
Solution Approach 2:
The patent uses elastomeric material with elastic properties to create both the closure flap and spring element. This composite material approach allows the closure device to function with a single material type that provides both structural integrity and elastic restoring force, simplifying manufacturing.
2Reliability
If multiple separate components are used in closure devices, then the closure function is achieved, but the assembly process becomes error-prone and complicated
Solution Approach 1:
The patent merges the spring element and closure flap into one integrated component. This single-component design eliminates the need for precise assembly of multiple parts, reducing assembly errors and simplifying the manufacturing process while maintaining reliable closure functionality.
3Reliability
If traditional closure devices with separate springs are used, then the passage opening can be closed, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent employs elastomeric material that inherently provides both the closure flap structure and the spring restoring force. This single-material solution reduces manufacturing complexity and cost compared to traditional multi-component designs requiring different materials for the flap and spring elements.
Solution Approach 2:
By integrating the spring element and closure flap into one component made from elastomeric material, the patent reduces the number of manufacturing steps and material types required, thereby lowering production costs while maintaining effective sealing functionality.
