Dual Communicator Camera System Data Transfer

Solution Overview

Problem

Existing camera systems face challenges in reducing data transfer time between interchangeable lenses and camera bodies, which affects camera activation time and operational efficiency.

Innovation Solution

The implementation of a communication system using two communicators, where one communicator performs unidirectional communication for high-speed data transfer and another for bidirectional communication, allowing simultaneous data transmission and reception using both circuits synchronized with a single synchronization clock signal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a single communicator is used for data transfer between interchangeable lens and camera body, then device complexity is reduced, but data transfer time increases

Engineering Contradiction:

Improvedata transfer timeVSAvoidcommunicator configuration

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The communication system is segmented into two independent communicators: a first communicator for unidirectional data transfer and a second communicator for bidirectional data transfer. This segmentation allows simultaneous data transfer operations without mutual interference, reducing overall data transfer time while maintaining manageable complexity through functional specialization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension to communication by adding a second communicator that operates independently from the first communicator. This dimensional expansion enables parallel data transfer paths, transforming a sequential communication model into a parallel one, thereby significantly reducing data transfer time.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Speed

If unidirectional communication is used for high-speed data transfer, then data transfer speed is improved, but communication flexibility deteriorates

Engineering Contradiction:

Improvedata transfer speedVSAvoidcommunication direction flexibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The communication system is segmented into two independent communicators: a first communicator for unidirectional data transfer and a second communicator for bidirectional data transfer. This segmentation allows simultaneous data transfer operations without mutual interference, reducing overall data transfer time while maintaining manageable complexity through functional specialization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second communicator is designed to handle both transmission and reception of data, providing multi-functional capability. This allows the system to maintain communication flexibility and adaptability while the first communicator handles high-speed unidirectional transfers, achieving both speed and versatility through functional distribution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If bidirectional communication is implemented using two communicators, then data transfer time is reduced, but system complexity increases

Engineering Contradiction:

Improvecamera activation timeVSAvoidcommunication control mechanism

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The controller dynamically switches between different communication modes (unidirectional and bidirectional) based on the specific data transfer requirements. This dynamic adaptability allows the system to optimize camera activation time by selecting the appropriate communication mode while managing complexity through intelligent control rather than fixed complex architecture.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The communication system is segmented into two independent communicators: a first communicator for unidirectional data transfer and a second communicator for bidirectional data transfer. This segmentation allows simultaneous data transfer operations without mutual interference, reducing overall data transfer time while maintaining manageable complexity through functional specialization.

Inventive Principle:

Principle #1Segmentation
