Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current splinting devices used by military medics for fracture stabilization are inadequate, causing increased soft tissue damage and providing less than ideal support, especially in battlefield environments where access to trauma care is limited.
Innovation Solution
A fiber-reinforced composite article with a multi-layer body comprising a fiber reinforcement layer impregnated with a thermosetting resin, encapsulating film, and an insulating barrier, which can be rapidly cured to provide rigid support and immobilization of injured body parts, using a resin distribution system for efficient resin delivery and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional splinting devices are used for fracture stabilization, then the device structure is simple and easy to manufacture, but the fracture stabilization is insufficient and soft tissue damage increases
Solution Approach 1:
The patent employs fiber reinforcement layers impregnated with thermosetting resin to create a composite splint structure. The fiber reinforcement provides tensile strength while the resin matrix binds the fibers and distributes loads, creating a composite material that significantly improves fracture stabilization capability compared to traditional single-material splints.
Solution Approach 2:
The patent utilizes rapid curing of thermosetting resin under elevated temperature conditions to transform the splint from a flexible precursor state to a rigid stabilized state. This parameter change in temperature and resin curing state enables the splint to achieve optimal mechanical properties for fracture stabilization while minimizing soft tissue damage.
2Loss of time
If rapid curing resin is used to achieve quick immobilization, then the stabilization speed improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The thermosetting resin is pre-applied to the fiber reinforcement layers during manufacturing, creating a prepreg structure. This preliminary action allows the resin to be evenly distributed and bonded to the fibers before use, simplifying the field application process while enabling rapid curing when activated by heat or other triggers.
Solution Approach 2:
The patent exploits the phase transition of thermosetting resin from a liquid or semi-liquid precursor state to a solid cured state through chemical reaction. This phase transition enables rapid immobilization as the resin transforms from a flexible state that allows molding to the injured body part, to a rigid state that provides immediate structural support.
3Strength
If multi-layer composite structure is implemented for improved stabilization, then the fracture support and immobilization effectiveness increase, but the device weight and size increase
Solution Approach 1:
The patent employs thin fiber reinforcement layers and่่ encapsulating films to create a multi-layer composite structure. These thin films and layers provide the necessary structural strength and immobilization capability while minimizing the addition of weight and bulk, allowing the splint to remain portable and easy to handle in emergency situations.
