Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex fastening means are provided on the mask body to fasten filter modules in a detachable manner, then the filter modules can be securely attached and detached, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the fastening function for filter modules with the existing coupling elements that are already present on the mask body for other purposes. The coupling elements are designed to serve dual functions: their original function and the additional function of detachably fastening filter modules. This merging eliminates the need for separate complex fastening mechanisms while maintaining secure attachment.
Solution Approach 2:
The coupling elements on the mask body are designed as multi-functional components that can both perform their original function and serve as fastening means for filter modules. By making the coupling elements universal, the patent avoids adding dedicated fastening means, thereby reducing device complexity while ensuring reliable detachable attachment of filter modules.
2Reliability
If complex fastening means are provided on the mask body to fasten filter modules in a detachable manner, then the filter modules can be securely attached and detached, but the manufacturing cost increases
Solution Approach 1:
The patent merges the fastening function into the existing coupling elements, eliminating the need to manufacture separate complex fastening components. This reduces the number of parts, simplifies the manufacturing process, and lowers production costs while maintaining secure detachable attachment of filter modules.
Solution Approach 2:
By designing coupling elements with multi-functionality, the patent avoids the need to produce dedicated fastening mechanisms. The same components serve multiple purposes, reducing manufacturing complexity and cost while ensuring reliable filter module attachment.
3Adaptability or versatility
If additional fastening elements are added to the mask body for filter module attachment, then detachable fastening is achieved, but the device complexity increases
Solution Approach 1:
The patent combines the detachable fastening capability with the existing coupling elements on the mask body. By integrating the fastening function into already-present components, the patent achieves adaptability for filter module attachment without increasing device complexity through additional elements.
Solution Approach 2:
The coupling elements are designed to be universal, serving both their original function and the additional function of providing detachable fastening for filter modules. This multi-functionality achieves versatility without adding complexity.
