Imaging Apparatus Mount Unit Segmented Electric Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face issues with electric contact short-circuiting due to varying communication voltages, which can lead to malfunction and reduced durability of accessories like lens apparatuses and intermediate devices.
Innovation Solution
The implementation of a mount unit with multiple electric contact groups, where one group communicates at a first voltage and another at a second voltage, with the second group's contacts disposed adjacent to the first, reducing the likelihood of short-circuiting and wear during mounting and detaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electric contacts are arrayed at the mount unit to enable communication at different voltages, then communication versatility is improved, but the likelihood of short-circuiting between adjacent contacts increases
Solution Approach 1:
The electric contacts are divided into multiple distinct groups (first electric contact group and second electric contact group) that are spatially separated. Each group is dedicated to specific communication voltage levels, preventing cross-voltage short-circuits while maintaining communication versatility through multiple groups.
Solution Approach 2:
Different regions of the mount unit are assigned different functional characteristics - the first electric contact group is configured for first voltage communication while the second electric contact group is configured for second voltage communication. This local differentiation ensures that each region operates at its designated voltage level without interfering with adjacent regions.
2Device complexity
If electric contacts are arrayed closely together to reduce mount unit size, then device compactness is improved, but wear and short-circuiting between contacts increases
Solution Approach 1:
By segmenting the contacts into separate groups with dedicated spatial locations, the design achieves compactness through efficient space utilization while preventing wear and short-circuiting through physical separation. The segmented structure allows contacts to be closely arranged within groups while maintaining distance between groups.
Solution Approach 2:
The mount unit structure itself acts as an intermediary that maintains appropriate spacing between different electric contact groups while allowing them to be arrayed in a compact overall configuration. This intermediary structure prevents direct contact between different voltage groups while enabling close packing.

AI summary
A camera body includes a DCL terminal, a DLC terminal, and a LCLK terminal, that perform communication with a lens apparatus by a first voltage, or a second voltage that differs from the first voltage. The camera body also includes a DLC2 terminal that is only used when communication using the DCL terminal, DLC terminal, and LCLK terminal is performed by the first voltage. The DLC2 terminal is disposed adjacent to the LCLK terminal.
