Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple optical systems are incorporated into a single lens barrel, then the imaging system can be compact, but the lens barrel structure becomes complicated and difficult to manufacture
Solution Approach 1:
The patent divides the complex multi-optical-system lens barrel into multiple simple cylindrical lens barrels, each housing one optical system. These standardized barrels can be manufactured independently and then assembled together, reducing manufacturing complexity while achieving compact integration.
Solution Approach 2:
The patent nests multiple cylindrical lens barrels within a single composite lens barrel structure. The simple cylindrical barrels are positioned adjacent to each other and integrated into one unified structure, allowing compact arrangement while maintaining simple individual components.
2Ease of operation
If multiple optical systems are incorporated into lens barrels with different structures, then proper orientations can be achieved, but the number of component kinds increases and manufacturing costs rise
Solution Approach 1:
The patent uses asymmetrical positioning of identical cylindrical lens barrels within the composite structure. By arranging the barrels in specific asymmetric positions and orientations within the composite lens barrel, the proper spatial orientations for imaging are achieved while keeping the barrel components themselves standardized and simple.
3Ease of manufacture
If multiple optical systems are incorporated into lens barrels with the same structure, then manufacturing costs are reduced, but additional components are needed between lens barrels affecting assembly accuracy
Solution Approach 1:
The patent merges multiple cylindrical lens barrels into a single composite lens barrel structure. By integrating the barrels directly into one unified composite structure without requiring additional intermediate components, assembly accuracy is improved while maintaining the simplicity and standardization of the individual barrel components.

AI summary
An optical system including two imaging optical systems and two holders including one holder to hold one imaging optical system and other holder to hold the other one imaging optical system. Each holder includes a lens positioner to determine a position of a lens constituting each imaging optical system, and two contacts disposed apart from the lens positioner. When the one holder is combined with the other holder, the two contacts of the one holder contact the two contacts of the other holder with the lens maintained at the position determined by the lens positioner of each holder.
