Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HVAC systems, such as Fan Coil Units, are manually controlled and lack adaptive intelligence, requiring cumbersome and costly wired installations for thermostats to adjust environmental conditions based on occupancy, which is inefficient and costly.
Innovation Solution
A wireless control system that uses sensing components to determine density information of living beings in a space and communicates with an HVAC control and management unit to dynamically adjust air end devices like FCUs, eliminating the need for wired connections and manual control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired thermostats are installed to manually control air end devices, then environmental conditions can be adjusted, but installation becomes troublesome and costly due to wiring requirements
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The thermostat communicates with air end devices through wireless signals (such as radio frequency communication) instead of physical wiring, eliminating the need for complex electrical installation while maintaining control functionality. This substitution resolves the contradiction by preserving ease of operation through remote control while dramatically reducing device complexity regarding installation wiring.
Solution Approach 2:
The patent introduces a wireless communication module as an intermediary between the thermostat and air end devices. This intermediary enables signal transmission without direct wired connections, allowing control functions to be maintained while avoiding the installation complexity of traditional wired systems. The wireless intermediary resolves the technical contradiction by decoupling the control function from the physical wiring requirement.
2Ease of operation
If manual control through thermostats is used, then air end devices can be adjusted, but the system lacks adaptive intelligence
Solution Approach 1:
The patent incorporates sensors that detect environmental parameters (such as temperature, humidity, and occupancy) and feed this information back to the control system. The system automatically adjusts air end device operations based on real-time sensor data, enabling adaptive control without requiring manual intervention. This feedback mechanism resolves the contradiction by maintaining ease of operation through automatic control while significantly improving adaptability to changing environmental conditions.
Solution Approach 2:
The system enables air end devices to self-adjust based on sensor inputs and pre-programmed logic. The thermostat automatically modifies operational parameters without human intervention, allowing the system to serve itself in adapting to environmental changes. This self-service capability resolves the technical contradiction by eliminating the need for manual control while enhancing adaptive intelligence through automated decision-making algorithms.
3Reliability
If wired thermostats are installed in predetermined positions, then control signals can be transmitted to air end devices, but installation cost increases due to wiring requirements
Solution Approach 1:
The patent replaces the mechanical wiring infrastructure with wireless communication technology. Signal transmission is achieved through electromagnetic waves rather than physical conductors, eliminating the need for expensive wiring installation while maintaining reliable communication between thermostats and air end devices. This substitution resolves the contradiction by preserving signal transmission reliability through wireless protocols while dramatically reducing installation costs by eliminating wiring requirements.
