Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If thermal caulking is performed without positional adjustment, then the device complexity is reduced, but the manufacturing precision of lens alignment deteriorates
Solution Approach 1:
The patent implements a positional adjusting mechanism that allows dynamic adjustment of the horn section and receiving base relative positions during the thermal caulking process. This enables the system to adapt to variations in lens frame dimensions and achieve precise lens alignment without requiring complex fixed adjustment mechanisms, thus resolving the contradiction between precision and complexity.
Solution Approach 2:
The patent changes the positional parameters of the horn section and receiving base by introducing a positional adjusting mechanism with adjustment sections that can modify the distance between these components. This parameter adjustment capability allows the system to compensate for manufacturing tolerances and achieve consistent high-precision lens alignment while maintaining relatively simple device structure.
2Reliability
If the horn section and receiving base are fixed in position, then the device complexity is reduced, but the lens-fixing quality deteriorates due to inability to compensate for dimensional variations
Solution Approach 1:
The patent introduces a positional adjusting mechanism that enables dynamic adjustment of the horn section and receiving base positions during the thermal caulking process. This dynamic adjustment capability allows the system to compensate for variations in lens frame dimensions and achieve reliable lens-fixing quality without requiring overly complex adjustment mechanisms, as the adjustment can be made during the process rather than requiring pre-programmed complex systems.
Solution Approach 2:
The patent implements a preliminary adjustment step before thermal caulking where the positional adjusting mechanism is used to set the correct relative positions of the horn section and receiving base. This preliminary action ensures that the lens frame is properly positioned before the thermal caulking begins, improving lens-fixing quality by preventing positioning errors while using a relatively simple adjustment mechanism compared to complex real-time control systems.
3Manufacturing precision
If thermal caulking is performed without eccentricity suppression, then the process time is reduced, but the manufacturing precision of lens positioning deteriorates
Solution Approach 1:
The patent implements a preliminary adjustment step before thermal caulking where the positional adjusting mechanism is used to align the horn section and receiving base, and the adjustment section is set to suppress eccentricity. This preliminary action prevents eccentricity issues from arising during the thermal caulking process, improving lens positioning precision without requiring time-consuming adjustments during the actual caulking operation, thus resolving the contradiction between precision and time loss.
Solution Approach 2:
The patent introduces an eccentricity detection section that provides feedback on the positioning accuracy during or after the thermal caulking process. This feedback mechanism allows the system to detect and correct any eccentricity in lens positioning, improving manufacturing precision while the feedback loop operates efficiently during the process, minimizing additional time loss compared to post-process inspection and adjustment methods.

AI summary
A lens-fixing device, in which thermal caulking is performed on a lens frame to fix a lens to the lens frame, includes: a receiving base on which the lens frame equipped with the lens is disposed; a horn section disposed at a position opposite to the receiving base and pressing and deforming an end section of the lens frame while the lens frame disposed at the receiving base is heated; a moving section moving at least one of the receiving base and the horn section in a direction of an axis for performing the thermal caulking; and a positional adjusting section adjusting relative positions of the receiving base and the horn section in a direction perpendicular to the direction of the axis by moving the at least one of the receiving base and the horn section in the direction perpendicular to the direction of the axis.
