Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electrical devices have complex and non-scalable control circuitry due to numerous interfaces and connection wires between master control panels and hardware modules, making maintenance costly and inefficient.
Innovation Solution
A control circuitry module group using a bus for communication and power supply between a master control module and slave modules, eliminating the need for individual interfaces and reducing wiring through a bus-based system that includes a bus control module and slave control modules with signal processing and power switching units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connection wires are used between master control panel and hardware modules, then reliable control is achieved, but device complexity increases and scalability deteriorates
Solution Approach 1:
Multiple separate control connections are merged into a single bus structure. The patent implements a shared communication bus that consolidates multiple individual control wires into one common medium, allowing the master control module to communicate with multiple slave control modules through this single bus, thereby reducing overall system complexity while maintaining control reliability.
Solution Approach 2:
The bus structure serves as a universal communication medium that can connect to multiple different slave modules. Instead of requiring dedicated control wires for each hardware module, the single bus can interface with various types of slave modules (heating, cooling, lighting, etc.), providing multi-functional connectivity and improving system scalability.
2Ease of operation
If individual interfaces are provided for each slave module, then direct control is achieved, but adaptability deteriorates and maintenance cost increases
Solution Approach 1:
The bus provides a universal interface that can accommodate multiple types of slave modules without requiring additional or modified physical connections. Each slave module connects to the same bus using a standardized interface, enabling the system to easily adapt to different module types and configurations, thereby improving scalability and versatility.
Solution Approach 2:
The system enables dynamic addition and removal of slave modules without requiring physical reconfiguration of control connections. Modules can be dynamically connected or disconnected from the bus, and the system automatically manages communication, allowing flexible adaptation to changing operational requirements.
3Loss of information
If multiple connection wires are used, then complete control signaling is achieved, but loss of substance increases due to excessive wiring
Solution Approach 1:
Multiple control signal paths are merged into a single shared bus medium. Instead of using separate wires for each control signal between master and slave modules, all control communications share the same physical bus, dramatically reducing the quantity of wiring material required while maintaining complete control signaling capability through time-multiplexed or address-based communication protocols.
