Solution Overview

Problem

Existing interchangeable-lens digital cameras require a large number of terminals for synchronous and asynchronous communication, leading to physical restrictions and inefficiencies in processing time.

Innovation Solution

Implementing at least one shared communication terminal for both synchronous and asynchronous communication, allowing commands to be communicated via the same terminal, reducing the number of terminals needed and enhancing communication efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate communication terminals are used for synchronous and asynchronous communication, then communication reliability is improved, but the number of terminals increases and physical restrictions occur

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidnumber of terminals

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines synchronous and asynchronous communication functions into a single shared communication terminal. The terminal can operate in synchronous mode when a synchronization signal is detected and in asynchronous mode when no synchronization signal is present, eliminating the need for separate terminals for each communication type.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The communication terminal is designed with multi-functionality to handle both synchronous and asynchronous communication protocols. By detecting the presence or absence of a synchronization signal, the terminal automatically adapts its operation mode, making it a universal communication interface that replaces multiple specialized terminals.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If multiple separate communication terminals are used, then communication stability is improved, but processing time increases due to more complex terminal management

Engineering Contradiction:

Improvecommunication stabilityVSAvoidprocessing time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

By merging synchronous and asynchronous communication capabilities into one terminal, the system reduces the complexity of terminal management and signal coordination. This consolidation eliminates the overhead associated with managing multiple separate terminals, thereby reducing processing time while maintaining communication stability through adaptive mode switching.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If separate terminals are allocated for synchronous and asynchronous communication, then communication efficiency is improved, but the physical space and terminal count increase

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidnumber of terminals

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent implements a universal communication terminal that can perform both synchronous and asynchronous communication functions. The terminal detects synchronization signals to determine the appropriate communication mode, allowing one terminal to replace what would traditionally require two separate terminals, thus reducing the quantity of terminals while maintaining communication efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)
