Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a simple guiding structure is provided on the electrical connector, then the connector can be inserted correctly and fixed on a correct position, but impact forces during insertion cause damage and reduce service life
Solution Approach 1:
The guiding post is divided into multiple segments including a guiding portion and an absorbing portion. The absorbing portion is further segmented into multiple elastic deformation regions that can independently deform to absorb impact forces, while the guiding portion maintains structural integrity for precise positioning.
Solution Approach 2:
The absorbing portion of the guiding post is designed with elastic deformation regions that act as pre-configured cushioning elements. These regions are positioned to absorb impact forces before they can damage critical components, providing beforehand protection against insertion shocks.
2Measurement precision
If a rigid guiding structure is used to ensure precise positioning, then insertion accuracy is improved, but the structure cannot absorb impact forces and suffers damage
Solution Approach 1:
Different portions of the guiding post have different mechanical properties. The guiding portion maintains rigidity for precise positioning, while the absorbing portion has elastic properties for impact absorption. This local differentiation of mechanical qualities resolves the contradiction between rigidity and impact resistance.
Solution Approach 2:
The guiding post transitions from a static rigid structure to a dynamic structure with elastic deformation regions. These regions can dynamically adjust their stiffness during insertion, remaining rigid during normal operation but deforming elastically under impact loads to absorb shock.
3Productivity
If multiple insertion operations are performed, then connectivity is maintained, but accumulated impact forces cause fatal damage to the connector
Solution Approach 1:
The elastic deformation regions in the absorbing portion serve as pre-configured shock absorbers that activate during each insertion operation. This beforehand cushioning protects the connector from cumulative damage that would otherwise occur with repeated insertion cycles.
Solution Approach 2:
The elastic deformation regions temporarily absorb impact energy during insertion by deforming, then recover their original shape after insertion is complete. This discarding of impact energy and subsequent recovery allows the connector to withstand multiple insertion operations without cumulative damage.

AI summary
An electrical connector with two guiding posts is disclosed. The electrical connector includes an insulation housing, multiple signal terminals and multiple power terminals. The insulation housing includes a flat base, a mating portion and two guiding posts. The mating portion forms multiple signal terminal insertion openings and multiple power terminal insertion openings. Each signal terminal has a head portion and a tail portion. The head portion is adjacent to the corresponding signal terminal insertion opening, and the tail portion extends out of the bottom surface of the insulation housing. Each power terminal has a head and a tail. The head is adjacent to the corresponding power terminal insertion opening, and the tail extends out of the bottom surface of the insulation housing. Each of the two guiding posts is symmetrically split into two separate sub guiding posts and forms a gap between the two sub guiding posts.
