Solution Overview
Problem
Existing respiratory protective devices face challenges in providing a secure and detachable strap component attachment system that ensures a comfortable and effective fit for users, with existing solutions often being cumbersome or difficult to adjust.
Innovation Solution
A respiratory protective device featuring a mask component with integrated fastener components, such as hook fasteners, that engage with a strap component made of 3D knitted material, allowing for selective and detachable attachment along multiple interfaces, including perimeter edges and lateral ends, facilitating a secure and adjustable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable strap component configuration is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The fastener components are integrally configured as part of the mask component, merging the fastening function into the existing structure. This eliminates the need for separate fastening mechanisms while enabling detachable strap configuration, thus improving ease of operation without proportionally increasing device complexity
Solution Approach 2:
The integrated fastener components serve multiple functions: they provide attachment points for straps, maintains structural integrity of the mask component, and enable selective detachment. This multi-functionality allows the system to achieve detachable configuration capability while using existing structural elements
2Adaptability or versatility
If multiple strap component interfaces are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The fastener components are distributed in multiple arrays along perimeter edge portions of the mask component, creating multiple strap component interfaces. This segmentation allows straps to be attached at different positions for various fit requirements, improving adaptability while maintaining a systematic and organized structure that limits complexity
3Ease of operation
If integrated fastener components are distributed along perimeter edges, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The fastener components are integrally configured with the mask component, merging the fastening elements into the mask structure during manufacturing. This integration ensures precise distribution of fastener components along perimeter edges without requiring separate attachment steps, thereby achieving both ease of operation and manufacturing precision
