Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens devices require complex communication line configurations for multiple connections to operation terminals, leading to increased load on the host side during lens action completion confirmation.
Innovation Solution
A lens device with a multi-purpose communication interface and a separate real-time trigger signal line allows independent control and immediate image capture post-action completion, enabling n-to-one or n-to-n connections via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-purpose communication interface is used for connecting multiple lens devices to operation terminals, then the connection versatility is improved, but the processing load on the operation terminal increases during lens action completion confirmation
Solution Approach 1:
The communication interface is segmented into two distinct parts: a multi-purpose communication interface for general control and data exchange, and a dedicated real-time trigger signal line for immediate action completion notifications. This segmentation allows the operation terminal to handle multiple lens devices through the multi-purpose interface while receiving instantaneous completion signals through the dedicated line, thereby reducing processing load and waiting time.
Solution Approach 2:
A separate real-time trigger signal line acts as an intermediary between the lens device and the operation terminal. This dedicated signal line directly transmits action completion information without requiring the operation terminal to continuously poll or process communications through the multi-purpose interface, thus reducing the processing burden on the operation terminal while maintaining versatile connectivity.
2Speed
If the operation terminal continuously monitors lens action completion through the multi-purpose communication interface, then the real-time response is improved, but the processing delays increase due to communication overhead
Solution Approach 1:
The system prepares two parallel communication paths in advance: the multi-purpose communication interface for general operations and the dedicated real-time trigger signal line for immediate notifications. By having the dedicated signal line ready beforehand, the system can instantly transmit action completion information without requiring real-time monitoring or polling through the multi-purpose interface, thereby eliminating communication overhead and processing delays.
3Productivity
If a separate real-time trigger signal line is added for immediate action completion notification, then the processing speed is improved, but the device complexity increases
Solution Approach 1:
The separate real-time trigger signal line is designed with a single dedicated function: transmitting action completion notifications. This specialization allows the signal line to operate independently and efficiently without requiring complex control logic or processing capabilities. The simplicity of its single-purpose design minimizes the increase in device complexity while maximizing processing speed for action completion notifications.
