Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic material is used for MT/MPO adapter to reduce costs, then manufacturing cost is reduced, but electromagnetic wave shielding capability deteriorates
Solution Approach 1:
The patent applies composite materials by combining plastic base material with conductive fillers (such as metal particles or conductive polymers) to create conductive plastic. This composite material simultaneously provides the cost benefits of plastic manufacturing while achieving the electromagnetic wave shielding capability of conductive materials, directly resolving the contradiction between manufacturing cost and shielding performance.
Solution Approach 2:
The patent changes the electrical conductivity parameter of the plastic material by adding conductive additives. By adjusting the concentration and distribution of conductive fillers within the plastic matrix, the material transitions from non-conductive to conductive, enabling electromagnetic wave shielding while maintaining the structural advantages and cost-effectiveness of plastic materials.
2Stability of the object's composition
If rigid material is used for flange plate to provide structural stability, then structural stability is improved, but abrasion resistance deteriorates
Solution Approach 1:
The conductive plastic used in the flange plate creates a composite structure that combines the structural stability of rigid materials with the abrasion resistance of elastic conductive materials. This composite approach allows the flange plate to maintain its shape and positioning function while reducing wear from repeated connector insertions and removals.
Solution Approach 2:
The elastic properties of the conductive plastic provide a flexible, compliant surface in the flange plate that can deform slightly to accommodate connector variations and reduce mechanical stress. This flexibility reduces abrasion while maintaining sufficient structural stability for proper connector alignment and retention.
3Object-affected harmful factors
If conductive plastic is used for MT port and MPO port to improve electromagnetic shielding, then electromagnetic wave shielding is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the electromagnetic shielding function with the structural housing material by making the MT port and MPO port housings themselves from conductive plastic. This eliminates the need for separate shielding components or coatings, simplifying the manufacturing process while achieving comprehensive electromagnetic wave shielding across all port surfaces.
Solution Approach 2:
The conductive plastic material serves multiple functions simultaneously: it provides the structural housing for the ports, achieves electromagnetic wave shielding, and reduces abrasion from connector mating operations. This multi-functionality reduces the number of separate components needed, thereby simplifying manufacturing despite the specialized material properties.
