Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nasal spreaders are often single-use, irritate the skin, are bulky, and pose safety risks due to their design, failing to effectively improve respiration and comfort while being invasive and exerting excessive pressure on nasal inner walls.
Innovation Solution
A nasal spreader made from an elastically deformable metallic wire, shaped to form spreader elements and a connecting element on a common plane, allowing easy insertion and reduced risk of damage, with a thread-like structure to distribute force and minimize bulk, pressure, and irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional nasal spreaders are used, then the nostrils can be opened, but they exert excessive pressure on the inner walls of the nose and cause skin irritation
Solution Approach 1:
The nasal spreader uses a thin wire structure instead of bulky traditional materials. The wire is flexible yet maintains sufficient elastic force to spread the nostrils while its thin profile minimizes contact area and pressure on the nasal inner walls, preventing skin irritation and discomfort during extended wear.
Solution Approach 2:
The invention changes the material parameter from bulky plastic or thick elastic materials to a thin metallic wire with specific elastic properties. This parameter change allows the spreader to maintain adequate spreading force while significantly reducing the pressure density on the nasal walls, resolving the contradiction between effectiveness and comfort.
2Force
If bulky nasal spreaders are used, then the spreading effect is achieved, but the obstruction caused by the bulk prejudiced the spreading effect
Solution Approach 1:
The spreader employs a thin wire structure with minimal volume that can still generate sufficient elastic force to diverge the nasal side walls. The wire's flexibility allows it to conform to the nasal cavity shape without creating obstruction, while its elastic properties ensure effective spreading action.
Solution Approach 2:
The wire is shaped into multiple segments including a first U-shaped loop for the nasal septum, second U-shaped loops for the nasal passages, and connecting elements. This segmentation allows the force to be distributed through multiple contact points rather than concentrated in a single bulky structure, achieving effective spreading with minimal obstruction.
3Force
If metallic filament spreaders with multiple loops are used, then the spreading effect is improved, but the structure causes damage if the nose is hit
Solution Approach 1:
The thin wire structure provides flexibility that absorbs impact energy through deformation rather than transmitting rigid force to the nasal tissues. Unlike rigid metallic filaments, the wire can bend and flex during impact, reducing the risk of damage while maintaining spreading effectiveness during normal use.
Solution Approach 2:
The spreader design allows dynamic adjustment of its configuration. The wire can change its shape in response to external forces such as impact, transitioning from a rigid spreading configuration to a more compliant state that accommodates sudden forces without causing damage.
4Force
If traditional nasal spreaders are used, then the nostrils can be opened, but they are single-use and can be effectively reused only a small number of times
Solution Approach 1:
The wire is made of elastic metallic material with specific mechanical properties that allow it to withstand repeated deformation cycles. The elastic modulus and yield strength parameters are selected to ensure the wire returns to its original shape after each use, enabling multiple reuses while maintaining consistent spreading capability.
Solution Approach 2:
The spreader uses a composite approach combining the elasticity of metallic wire with a thin profile. This material selection provides both the necessary force for spreading and the durability for repeated use, overcoming the single-use limitation of traditional elastic material spreaders.
