HVAC Radio Path Switching Between Components During User Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Climate control systems, such as HVAC systems, face challenges with maintaining signal connectivity between portable devices and system hubs due to limitations in short-range radio connections, which can degrade with increasing distance and interference, leading to loss of connectivity when users move between components of the system.
Innovation Solution
The method involves establishing connections between portable devices and system hubs along multiple signal pathways, including short-range radio connections, and dynamically re-routing these connections based on monitored parameters to ensure seamless communication, even when users physically move between different components of the HVAC system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a short-range radio connection is used between portable device and HVAC component, then ease of operation is improved, but reliability deteriorates when user moves away from the component
Solution Approach 1:
The system divides the communication path into multiple segments by introducing intermediate components (first and second HVAC components) that can each independently establish radio connections with the portable device. This segmentation allows the signal to be relayed through different paths, maintaining connectivity even when one direct path becomes unavailable due to user movement.
Solution Approach 2:
The patent employs intermediary HVAC components that act as mediators in the communication chain. When the user moves away from the first component, the second component serves as an intermediary to maintain the connection, receiving and forwarding signals to ensure continuous communication between the portable device and the system.
2Reliability
If multiple signal pathways are established, then reliability is improved, but device complexity increases
Solution Approach 1:
The HVAC components are designed with multi-functionality, serving both their primary climate control functions and secondary communication relay functions. This universality allows the same hardware to perform multiple roles without adding separate dedicated relay devices, thereby maintaining reliability through multiple pathways while minimizing additional complexity.
Solution Approach 2:
The system implements self-service through automatic pathway selection and switching. The HVAC components autonomously monitor connection quality and seamlessly switch between different signal pathways without requiring user intervention or complex manual configuration, reducing operational complexity while maintaining multiple active pathways for reliability.
