Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If steel plates or simple splints combined with bandages are used for fixation, then the fixation can be achieved, but the flat plates do not conform to irregular limb surfaces, creating gaps that lead to soft-tissue compression and potential skin damage
Solution Approach 1:
The patent employs curved and contoured splint surfaces that match the natural curvature of limb anatomy. The splints are designed with non-flat, three-dimensional contours that conform to the irregular surfaces of arms and legs, eliminating gaps between the fixation device and the limb surface, thereby preventing soft-tissue compression while maintaining effective immobilization.
Solution Approach 2:
The splints feature varying local properties including different curvature radii, thickness distributions, and surface geometries at different locations to match the specific anatomical characteristics of various limb regions. This localized adaptation ensures optimal contact and distribution of pressure across the limb surface, preventing focal compression points.
2Productivity
If manual reduction followed by fixation using steel plates or simple splints is performed, then fracture fixation can be achieved, but the process is time-consuming and complex, unable to quickly stabilize the fracture
Solution Approach 1:
The fixation system is divided into modular components including pre-shaped splints, quick-connect fasteners, and adjustable strapping systems. This segmentation allows each component to be independently prepared and rapidly assembled, eliminating the need for complex intraoperative shaping and fixation procedures, thereby significantly reducing treatment time while maintaining stabilization effectiveness.
Solution Approach 2:
The splints are pre-formed with predetermined curved shapes and structural configurations suitable for common fracture patterns. This preliminary preparation eliminates the need for time-consuming customization and adaptation during emergency treatment, allowing immediate application and rapid stabilization of fractures in pre-hospital and emergency settings.
3Ease of operation
If inadequate immediate fixation and bandaging are applied after fracture, then the treatment process is simplified, but abnormal movement at the fracture site worsens injuries
Solution Approach 1:
The splint system incorporates self-aligning features and intuitive attachment mechanisms that automatically ensure proper positioning and secure fixation without requiring complex manipulation or specialized training. The design includes self-adjusting straps, automatic locking fasteners, and guide features that guide correct application, making the procedure simple for first responders while ensuring reliable fracture stabilization.
