Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neonatal transport devices fail to adequately reduce vibrations during transportation, which can be harmful to infants, and do not accommodate various sizes and weights while ensuring proper restraint and maximum workspace.
Innovation Solution
A device comprising an upper plank, a lower plank, and spring assemblies, such as wire rope isolators, that provide a uniform spring rate in multiple directions to dampen vibrations, and can be easily adapted to existing isolettes, allowing for secure infant restraint and maximum workspace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid support structures are used in neonatal transport devices, then structural stability is improved, but vibration transmission to the infant increases
Solution Approach 1:
The patent introduces spring assemblies as intermediary elements between the support structure and the infant mattress. These springs act as a mediator that decouples the rigid support structure from the infant, allowing the structure to remain stable while the springs absorb and dampen vibrations before they reach the infant.
Solution Approach 2:
The patent incorporates vibration-dampening spring assemblies in advance within the support structure, before vibrations can be transmitted to the infant. This preemptive cushioning approach ensures that vibrations are attenuated before reaching the harmful zone, rather than attempting to mitigate them after transmission.
2Object-affected harmful factors
If vibration reduction mechanisms are added to neonatal transport devices, then vibration transmission is reduced, but device complexity increases
Solution Approach 1:
The patent employs flexible spring assemblies that can be integrated into the existing support structure framework. These flexible elements provide vibration reduction without requiring complex rigid mechanisms, maintaining a relatively simple overall device architecture while achieving the desired vibration attenuation.
Solution Approach 2:
The patent introduces dynamic spring elements that can adaptively respond to vibration frequencies and amplitudes. This dynamic approach allows the vibration reduction mechanism to function effectively across varying transport conditions without requiring complex active control systems or multiple fixed configurations.
3Strength
If the support structure is made more rigid to support various infant sizes, then load-bearing capacity is improved, but adaptability to different infant sizes decreases
Solution Approach 1:
The spring assemblies provide a dynamic support system that can adapt to different infant weights and sizes. The springs compress and extend based on the load applied, automatically adjusting to accommodate various infant sizes while maintaining adequate support, eliminating the need for rigid adjustable mechanisms.
Solution Approach 2:
The patent utilizes the changing physical parameters of the spring assemblies (compression, extension, deflection) in response to different infant weights. This parameter-based adaptation allows the same rigid support structure to safely accommodate a range of infant sizes through the compliant spring elements that adjust their mechanical response based on the applied load.
