Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a metal pin and metal rod are used to connect and adjust the angle block, then the angle adjustment function is achieved, but the structure becomes complex and the assembly process becomes lengthy
Solution Approach 1:
The patent combines the angle block and mounting base into a single integrated component, eliminating the need for separate metal pins and rods. The angle block is directly formed as one piece with the mounting base, merging multiple parts into one structure that achieves angle adjustment without complex assembly mechanisms.
Solution Approach 2:
The integrated angle block-mounting base structure serves multiple functions simultaneously: it provides structural support, enables angle adjustment, and eliminates the need for separate connection components. This multi-functional design reduces overall device complexity while maintaining the angle adjustment capability.
2Ease of operation
If multiple parts and metal components are used for angle adjustment, then the angle block can be rotated and positioned, but the operation becomes complicated and time-consuming
Solution Approach 1:
By merging the angle block and mounting base into one integrated component, the patent eliminates multiple assembly steps and connection operations. The single-piece structure allows for rapid angle adjustment without the need to assemble or disassemble separate metal parts, significantly reducing operation time and complexity.
3Device complexity
If a simple plastic structure is used for the needle guiding bracket, then the assembly process is simplified, but the angle adjustment and positioning become less stable
Solution Approach 1:
The patent changes the physical state of the plastic material from rigid to elastic by incorporating elastic deformation capabilities. The elastic arms can flex and return to their original position, providing stable angle positioning while maintaining the simplicity of the plastic structure. This parameter change enables the plastic to perform functions previously requiring metal components.

Function Achieved in This Case
The solution enables convenient and stable angle adjustments with reduced risk of loosening, thanks to the elastic deformation of the arms and the compression spring providing consistent support, resulting in a more user-friendly and reliable device.
Implementation Method 1
the angle block is further provided with an elastic element which applies elastic force to the elastic arm to urge the raised positioning platform to be embedded within the angle gear grooves
