Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional needle without deformable parts is used, then the structure is simple and easy to manufacture, but the injection efficiency of medical fluid is poor
Solution Approach 1:
The needle end is designed with deformable parts that can change shape during insertion and fluid injection. The deformable parts include inclined surfaces and elastic structures that dynamically adapt to tissue resistance, improving fluid ejection efficiency while maintaining a relatively simple overall needle structure for manufacturing
Solution Approach 2:
The needle geometry is optimized by changing parameters such as the angle of deformable parts, thickness of needle wall, and configuration of fluid holes. These parameter changes enhance the injection efficiency without fundamentally altering the basic needle structure, thus balancing performance improvement with manufacturing simplicity
2Reliability
If a medical thread is inserted into muscle tissue, then autogenous material generation is induced and muscle strengthening occurs, but the insertion process is difficult and time-consuming
Solution Approach 1:
The medical thread is pre-attached to the needle before insertion. The needle acts as a delivery vehicle that carries the thread through the skin and into the muscle tissue in a single puncture action, eliminating the need for separate insertion steps and reducing procedural complexity
Solution Approach 2:
The needle serves as an intermediary tool that facilitates thread insertion into difficult-to-reach muscle areas. The needle's sharp point and controlled delivery mechanism enable precise placement of the thread deep within muscle tissue without requiring complex manual manipulation techniques
3Reliability
If the contact area between the medical thread and muscle tissue is increased, then autogenous material generation is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The medical thread is designed with a porous structure that increases its surface area and contact points with muscle tissue. This porous configuration promotes better interaction with tissue cells and enhances autogenous material generation while maintaining a relatively simple thread geometry that can be manufactured using conventional extrusion or knitting processes
Solution Approach 2:
The thread structure transitions from a simple linear form to a three-dimensional mesh or porous configuration. This dimensional change increases the effective contact area with tissue without significantly complicating the manufacturing process, as the porous structure can be created through standard textile or polymer processing techniques
