Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a collimator lens is disposed in an outer frame without a support mechanism, then the device complexity is reduced, but the posture stability of the collimator lens deteriorates
Solution Approach 1:
The support mechanism is divided into distinct functional components: a positioning surface provided on the outer frame for abutting the collimator lens, and a biasing member (separate from the pressing member) that applies elastic force. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity.
Solution Approach 2:
The positioning surface is pre-configured on the outer frame at a predetermined position to abut the collimator lens. This preliminary arrangement ensures that when the optical connector is assembled, the collimator lens is automatically positioned and maintained in the correct posture without requiring additional adjustment mechanisms, thus preventing posture changes before they can affect optical communication reliability.
2Stability of the object's composition
If a support mechanism with biasing member and pressing member is added, then the posture stability of the collimator lens is improved, but the device complexity increases
Solution Approach 1:
The biasing member is configured to elastically press the collimator lens against the positioning surface, creating a self-adjusting support system. The elastic force automatically compensates for minor variations in assembly tolerances and maintains constant pressure to prevent posture changes, eliminating the need for complex adjustment mechanisms or multiple support structures.
Solution Approach 2:
The support mechanism integrates multiple functions into a compact arrangement: the positioning surface on the outer frame combines with the biasing member and pressing member to simultaneously provide positioning, support, and posture maintenance functions. This merging of functions achieves reliable collimator lens stabilization without adding excessive structural complexity to the overall device.
3Stability of the object's composition
If the collimator lens is pressed firmly against the positioning surface, then the posture maintenance is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The biasing member is designed to apply elastic force that can be controlled within a specific range, allowing the pressing force on the collimator lens to be optimized. By adjusting the elastic force parameter, the system achieves reliable posture maintenance while accommodating normal variations in manufacturing tolerances of the positioning surface and collimator lens, thereby reducing the stringency of manufacturing precision requirements.

AI summary
An optical connector includes an outer frame, having a cylindrical shape, into which a part of an optical transmission line for transmitting an optical signal is inserted, the outer frame covering an emission end for an optical signal of the optical transmission line; a collimator lens provided in the outer frame and facing the emission end; and a support mechanism that is disposed in the outer frame and that maintains a posture of the collimator lens in the outer frame. A positioning surface that abuts on the collimator lens to maintain the posture of the collimator lens in the outer frame is provided in the outer frame. The support mechanism includes a biasing member and a pressing member that presses the biasing member and biases the collimator lens toward the positioning surface with the biasing member.
