Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diameter of the cylindrical body is fixed, then the manufacturing cost is reduced, but the compatibility with different aperture sizes is poor
Solution Approach 1:
The cylindrical body incorporates an obconical structure that enables dynamic adjustment of the effective diameter. By rotating the obconical structure relative to the cylindrical body, the engagement diameter can be changed to match different aperture sizes, transforming a static structure into a dynamically adjustable one that adapts to various positioning hole diameters on PCBs
Solution Approach 2:
The invention changes the diameter parameter of the cylindrical body by introducing an obconical structure with adjustable rotation. This allows the effective engagement diameter to vary between a first diameter (when engaged with carrier tape) and a second diameter (when engaged with PCB positioning holes), enabling compatibility with different aperture sizes through parameter transformation
2Ease of operation
If the angle between the lower end surface of the coronal structure and the outer side of the cylindrical body is a right angle, then the manufacturing precision is improved, but the ease of detachment from carrier tape is poor
Solution Approach 1:
The invention applies different geometric characteristics to different parts of the coronal structure. The lower end surface has a sloped angle (not a right angle) to facilitate easy detachment from the carrier tape, while other portions of the coronal structure maintain precise angular relationships for proper engagement. This local differentiation resolves the contradiction between ease of detachment and manufacturing precision
3Adaptability or versatility
If multiple products of different diameters are manufactured to meet different aperture needs, then the adaptability is improved, but the production cost increases and capacity utilization decreases
Solution Approach 1:
The invention creates a universal terminal connector that can serve multiple functions by accommodating different aperture sizes. The obconical structure within the cylindrical body can be rotated to present different effective diameters, allowing a single product design to replace multiple specialized products, thereby improving production efficiency and capacity utilization while maintaining adaptability

AI summary
A terminal connector with better compatibility; comprising a cylindrical body, and the upper end of the cylindrical body is set with a coronal structure; an obconical structure is set on the cylindrical body, and the obconical structure is annularly protruded from the outer peripheral surface of the cylindrical body, the obconical structure is spaced apart from the coronal structure; the obconical structure comprises an annular upper end surface and an annular conical surface; through the design of the obconical structure, the diameter of the cylindrical body can be gradually increased from the bottom to the top of the obconical structure; wherein, a plurality of damping patterns is set on the annular conical surface of the obconical structure. The utility model can be compatible with the positioning holes of different apertures during the assembly with PCB and also has greater tolerance for the tolerance of the flatness of the PCB surface, and it has the advantages of saving production cost and high capacity utilization. In addition, the design of the neck improves the reliability of positioning on the carrier tape and the design of slope on the lower end surface of the coronal structure makes the product easily detach downwardly from the carrier tape, thereby improving the fluency of production.
