Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the LED device is mounted using the conventional method with stopping portions and elongated slots, then the LED device can be retained in the receiving cavity, but the assembling process becomes complex and difficult for mass production
Solution Approach 1:
The receiving cavity is segmented into multiple functional zones: a retention area with stopping portions for lateral positioning, an elongated slot for leg insertion, and a pressing area for securing the LED device. This segmentation allows each zone to perform its specific function independently, simplifying the overall assembly process while ensuring reliable LED device retention.
Solution Approach 2:
The insulating housing is pre-formed with integrated stopping portions and elongated slots during molding, eliminating the need for separate assembly steps to create these features. The LED device legs are pre-inserted into the slots before the housing is pressed together, preparing the assembly for final securing in a single efficient operation suitable for mass production.
2Manufacturing precision
If the LED device is securely retained in the receiving cavity, then the illuminant portion is properly positioned, but the assembling process is not facility for mass production
Solution Approach 1:
Multiple retention functions are merged into a single integrated receiving cavity structure within the insulating housing. The stopping portions, elongated slots, and pressing surfaces are all combined in one molded component, eliminating the need for multiple separate retention mechanisms and simplifying the assembly process for mass production while maintaining precise LED device positioning.
Solution Approach 2:
The receiving cavity structure is designed to automatically guide and position the LED device during assembly. The elongated slots self-align with the LED legs, and the stopping portions automatically engage with the illuminant portion, reducing the need for complex alignment procedures and manual adjustment, thereby improving both positioning precision and production efficiency.

AI summary
An electrical connector includes a display device (3) having an illuminant portion (31) and legs (32) extending from the illuminant portion. An insulating housing (1) has a front wall (111), a rear wall (112), four side walls (113) and a receiving cavity (13) recessed from one side wall (113A) and running though the front wall (111) so as to form a retaining portion (141) and at least one first blocking portion (142) at a front section thereof. A plurality of terminals (2) are mounted in the insulating housing thereof. The retaining portion (141) is located at an outer side of the receiving cavity (13) and over the illuminant portion (31) to prevent the illuminant portion from outward moving, and the first blocking portion (142) is located in front of the illuminant portion (31) and abuts against the illuminant portion to prevent the illuminant portion from forward moving.
