Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional card edge connector design is used, then the structure is simple and manufacturing is easy, but the appearance is plain and light transfer capability is insufficient
Solution Approach 1:
The connector is divided into functional zones: transparent members for light transmission, metallic shell with through-holes for light emission, and insulative housing for structural support. Each segment serves a specific function, allowing light to pass through the transparent member and exit via the through-holes in the metallic shell, thereby improving light transfer capability while maintaining manageable structural complexity
Solution Approach 2:
The connector combines multiple materials with different optical properties: transparent members (for light transmission), metallic shell (for light emission and structural strength), and insulative housing (for electrical isolation and support). This composite structure enables both aesthetic appeal through light effects and functional performance
2Shape
If transparent members and through-holes are added to the card edge connector, then the light transfer capability and appearance are improved, but the manufacturing complexity increases
Solution Approach 1:
The design separates the light transmission function (transparent members) from the light emission function (through-holes in metallic shell), allowing each component to be manufactured independently using suitable processes and then assembled. This segmentation enables the use of appropriate manufacturing techniques for each material type while maintaining overall aesthetic quality
Solution Approach 2:
The metallic shell serves multiple functions: providing structural support, enabling light emission through its through-holes, and offering an aesthetically pleasing appearance. The transparent members simultaneously provide light transmission and visual appeal. This multi-functionality reduces the need for additional specialized components, thereby managing manufacturing complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a visually appealing card edge connector with efficient light transfer capabilities, addressing the market's demands for both appearance and functionality by utilizing transparent members and strategically designed through-holes in the metallic shell.
Implementation Method 1
Each of the covering portions comprises a plurality of through-holes arranged along the longitudinal direction and located above the transparent members to leak out the light transferred therefrom

AI summary
A card edge connector includes a longitudinal insulative housing, a number of terminals retained in the insulative housing, a pair of transparent members mounted to the insulative housing, and a metallic shell surrounding around the insulative housing. The insulative housing has two side walls extending along a longitudinal direction, two end walls connecting between the longitudinal ends of the two side walls and a center slot defined therebetween. The metallic shell includes two covering portions respectively located above the two side walls in a vertical direction perpendicular to the longitudinal direction. Each of the covering portions has a number of through-holes arranged above the transparent members to leak out the light transferred therefrom.
