Control Module for Human-Machine Dialogue Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing man-machine dialogue systems are complex and expensive due to the use of intelligent elements with microprocessors and memory, requiring a more simplified and cost-effective solution for controlling dialogue organs with minimal wiring.
Innovation Solution
A control module with a microcontroller that uses a common terminal and dedicated terminals to read and write states of electrical contacts and indicators through alternating voltage periods, minimizing the number of wires needed and eliminating the need for intelligence in dialogue units, connected via a network of twisted cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intelligent man-machine dialogue elements with microprocessors and memory are used, then the system can store and process data locally, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent extracts the intelligence (microprocessor and memory) from the individual dialogue elements and concentrates it in a single external control module. This allows the dialogue elements to become simple passive components while the control module handles all data processing and storage functions centrally.
Solution Approach 2:
The control module serves multiple functions: it controls all dialogue elements, stores their states, processes data, and manages communication. This single multi-functional unit replaces what would otherwise require intelligence in each individual element, reducing overall system complexity.
2Adaptability or versatility
If each man-machine dialogue organ is equipped with intelligence including microprocessor and memory, then each unit can independently process information, but the manufacturing cost increases
Solution Approach 1:
The intelligent processing capability is extracted from each individual dialogue organ and relocated to a shared control module. This eliminates the need for expensive microprocessors and memory in each unit while maintaining the system's overall processing capability through the central controller.
Solution Approach 2:
Instead of having each unit with its own intelligence, the patent uses a single control module that serves all units. The control module can be replicated or upgraded independently, and its control logic can be copied to manage multiple dialogue elements without duplicating hardware intelligence in each element.
3Ease of operation
If a control system addresses each man-machine dialogue organ individually, then precise control is achieved, but the wiring complexity increases
Solution Approach 1:
The patent merges all control and addressing functions into a single control module that communicates with dialogue elements through a standardized interface. This consolidation reduces wiring complexity compared to individual addressing of each element, as the control module can sequentially or selectively address elements through a unified communication path.
