Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interchangeable-lens camera systems face challenges in mounting and functioning with existing lenses due to differences in mount specifications and communication standards, preventing the use of various optical systems.
Innovation Solution
An adapter system with a first mount section for the camera body and a second mount section for the interchangeable lens, along with an adapter control section that communicates lens information between the camera body and lens, using different methods based on the type of information, enabling compatibility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adapter is introduced to enable existing lenses to function on new camera bodies, then compatibility and versatility are improved, but device complexity increases due to additional communication protocols and electrical connection requirements
Solution Approach 1:
The adapter serves as an intermediary device between the camera body and interchangeable lens, containing a control section that mediates communication between the two. The adapter control section receives lens information from the lens through a first communication method and transmits it to the camera body through a second communication method, enabling compatibility without requiring direct communication between incompatible components.
Solution Approach 2:
The adapter control section is designed to handle multiple types of lens information (focal length, aperture value, lens ID, manufacturing date, etc.) using different communication methods appropriate for each data type. This multi-functional approach allows a single adapter design to support various lens types and information formats, enhancing universal compatibility.
2Measurement precision
If multiple communication methods are used to transmit different types of lens information, then information transmission accuracy is improved, but the ease of operation deteriorates due to automated communication processes
Solution Approach 1:
The adapter control section automatically selects and executes the appropriate communication method based on the type of lens information being transmitted. The system performs self-service by autonomously determining whether to use the first or second communication method for each piece of lens information, eliminating the need for user intervention in communication protocol selection while ensuring accurate information transmission.
Solution Approach 2:
The system implements feedback mechanisms where the adapter control section receives lens information from the lens, processes it according to the appropriate communication method, and transmits it to the camera body. The camera body receives the transmitted information and can verify its correctness, creating a feedback loop that ensures accurate information transmission without requiring manual verification by the user.

AI summary
An adapter includes: a first mount section that is detachably attached to a camera body; a second mount section that is provided separately from the first mount section and is detachably attached to an interchangeable lens; and an adapter control section that is capable of communicating between the camera body mounted on the first mount section and the interchangeable lens mounted on the second mount section. The adapter control section provides body transmission lens information for transmission to the camera body, on the basis of lens information requested from the camera body and lens information received from the interchangeable lens, through mutually different methods according to types of the lens information.
