Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration and air conditioning systems face inefficiencies in data transmission and response management between multiple units, leading to bandwidth constraints and increased device load due to unnecessary responses.
Innovation Solution
A communication method where communication nodes generate messages with attributes indicating necessary or unnecessary responses based on the type of information, allowing devices to determine and manage responses accordingly, using OFDM modulation and multi-hop functions for extended signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all communication nodes transmit and respond to all received messages, then complete information exchange is achieved, but communication bandwidth is consumed and device load increases
Solution Approach 1:
The patent applies local quality by making each communication node selectively respond based on the specific type of message received. Different message types (control messages, status messages, error messages) trigger different response behaviors. This allows the system to maintain reliable information exchange for critical messages while avoiding unnecessary responses for non-critical messages, thereby reducing overall bandwidth consumption.
Solution Approach 2:
The patent implements dynamics by enabling communication nodes to dynamically adjust their response behavior based on message attributes. The response determination is not static but adapts according to the message type, priority level, and current system state. This dynamic approach optimizes bandwidth usage by responding only when necessary while maintaining reliability for important communications.
2Ease of operation
If all communication nodes respond to all messages, then comprehensive control is achieved, but device processing load increases
Solution Approach 1:
The patent reduces device processing load by applying local quality to the response determination process. Each node evaluates message-specific attributes and applies appropriate response rules rather than uniformly responding to all messages. This selective processing maintains comprehensive control for necessary operations while significantly reducing unnecessary processing overhead.
Solution Approach 2:
The patent extracts the essential response requirement from each message by analyzing message types and attributes. Only the necessary responses are generated and transmitted, while unnecessary responses are eliminated. This extraction approach maintains control comprehensiveness by preserving all critical control functions while removing redundant processing operations that increase device load.
3Productivity
If message attributes are added to indicate response requirements, then response optimization is achieved, but message structure complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining standardized message attributes and response type indicators in the message protocol. These attributes are prepared in advance and embedded in message structures before transmission. This approach enables receiving nodes to quickly determine appropriate responses without complex real-time analysis, thereby improving communication efficiency while keeping message structure manageable through standardization.
