Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current medical training devices are used, then training can be conducted, but the devices lack flexibility and realism in simulating various spinal conditions and procedures
Solution Approach 1:
The training device is divided into multiple independent components: simulated skin layer, simulated vertebrae, tube simulating spinal cord, simulation fluid, and fastening members. Each component can be independently selected, configured, and replaced to simulate different spinal conditions and procedures, providing flexibility without requiring complete device redesign.
Solution Approach 2:
The device is designed to perform multiple training functions using the same basic structure. The simulated skin layer can be punctured for various procedures, the tube can be filled with different fluids to simulate different conditions, and the fastening members can secure the device in various positions, allowing one device to train multiple spinal procedures.
2Reliability
If realistic simulation of spinal procedures is implemented, then training fidelity is improved, but safety risks from needle sticks and injuries increase
Solution Approach 1:
The device creates a safe copy of the actual spinal structure using simulated materials. The simulated skin layer replicates the appearance and tactile properties of real skin, the tube replicates the spinal cord structure, and the simulation fluid replicates spinal fluid properties, allowing realistic training without exposure to actual biological hazards.
Solution Approach 2:
The simulated materials act as an intermediary between the training needle and any potential harm. Needles can be inserted and manipulated as in real procedures, but the simulated skin layer and tube provide a barrier that prevents actual injury, blood exposure, or contamination while maintaining procedural realism.
3Duration of action of stationary object
If durable and reusable materials are used, then device longevity is improved, but the ability to simulate realistic tissue properties may be compromised
Solution Approach 1:
The simulated skin layer uses composite materials combining durability with tissue-like properties. The simulation fluid uses reusable fluid that can be drained and refilled multiple times. These composite solutions maintain realistic tissue simulation characteristics while withstanding repeated use and sterilization processes.
Solution Approach 2:
The simulation fluid can be drained from the tube after use and the same fluid can be refilled and reused. The simulated skin layer and other components are designed to withstand multiple sterilization cycles, allowing the same physical components to be recovered, cleaned, and reused many times while maintaining their simulation properties.
4Productivity
If the simulated skin layer can self-repair after needle insertion, then multiple procedures can be performed, but the complexity of the material increases
Solution Approach 1:
The simulated skin layer is designed with self-sealing properties that automatically close puncture sites after needle removal without requiring external intervention. This self-service capability allows the same skin layer to be used for multiple needle insertions and procedures, increasing productivity while the self-sealing mechanism is integrated into the material design rather than requiring additional components.

AI summary
Described and demonstrated herein are embodiments of a wearable training device that is capable of realistic simulation of a plurality of spinal column regions for training of multiple procedures. In a simulated training procedure, a user may pierce the outer skin of the training device with a syringe needle. The user may direct the syringe needle to a tube within the vertebrae that simulates a spinal cord. The user may pierce the tube and use the syringe to extract the fluid from the tube and/or inject fluid into the tube and remove the syringe from the training device.
