Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable protection devices are not sufficiently safe, secure in positioning, and cost-effective, and lack flexibility for different body parts, with complex assembly processes.
Innovation Solution
A protection device comprising inflatable segments with side-by-side configurations, fixed to covers via peripheral engagement portions, allowing for quick assembly and robust structure, ensuring correct positioning and operation, and made from materials like polyurethane and PVC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bag is directly housed in a pocket of a garment with layers facing garment layers, then the structure is simple, but the positioning is not secure and reliability is reduced
Solution Approach 1:
The inflatable bag is divided into multiple segments (first segment, second segment, etc.) that can be independently positioned and secured within the garment pocket. Each segment has its own attachment portions that can be constrained at different seams, providing distributed securement points that enhance positioning reliability without requiring a completely complex overall structure.
Solution Approach 2:
The inflatable bag segments are nested within the garment pocket structure, with the bag layers positioned between inner and outer garment layers. The attachment portions extend through the pocket to engage with seams, creating a nested configuration that secures the bag in place while maintaining relative structural simplicity.
2Reliability
If multiple attachment portions are provided to enable correct positioning, then positioning security is improved, but manufacturing complexity and production costs increase
Solution Approach 1:
The attachment portions are merged with the bag structure itself during the manufacturing process. The seams that attach the bag segments to the garment also serve to constrain the attachment portions, combining multiple functions (bag attachment and positioning constraint) into a single manufacturing operation, thereby reducing overall production complexity and cost.
Solution Approach 2:
The attachment portions serve multiple functions: they attach the inflatable bag to the garment and simultaneously provide positioning constraints when engaged at the seams. This multi-functionality reduces the need for separate positioning mechanisms, simplifying manufacturing and reducing production costs while maintaining positioning security.
3Reliability
If the protection device is designed for specific body parts, then protection effectiveness is improved, but adaptability to different body parts is reduced
Solution Approach 1:
The protection device is divided into multiple inflatable segments that can be independently sized and shaped. Each segment can be configured for specific body parts (thorax, abdomen, hips, etc.) while the overall system maintains adaptability through the modular segmental structure, allowing different combinations of segments for different applications.
Solution Approach 2:
The dimensions, shapes, and configurations of the inflatable segments can be varied to adapt to different body parts. By changing parameters such as segment length, width, and attachment portion positions, the same basic device structure can provide effective protection for multiple body regions, maintaining both effectiveness and versatility.
