Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate control boxes are used for different HVAC equipment, then each device can be controlled independently, but the space occupation increases and the overall appearance is affected
Solution Approach 1:
The patent integrates multiple separate control boxes into a single integrated control device that can control all HVAC equipment (air conditioner main machine, chilled water pump, cooling water pump, thermal water pump, cooling tower, boiler, and motorized valves). This consolidation reduces space occupation while maintaining independent control capability through a unified control interface.
Solution Approach 2:
The integrated control device is designed to perform multiple functions by controlling various types of HVAC equipment through a single unit. It includes control circuits for different device types and can adapt to control different equipment configurations, providing universal control capability without requiring separate specialized control boxes for each device.
2Ease of operation
If field-bus manual wiring is used for control box arrangement, then basic device control is achieved, but the technical requirement on field workers increases and the arrangement period is prolonged
Solution Approach 1:
The patent replaces the mechanical field-bus wiring system with a wireless communication system. The integrated control device communicates with all HVAC equipment through wireless signals, eliminating the need for manual field wiring. This substitution maintains full control functionality while dramatically reducing installation time and technical requirements for field workers.
3Adaptability or versatility
If control boxes are designed according to different power configurations, then device-specific control is achieved, but the specifications vary and affect the whole appearance
Solution Approach 1:
The integrated control device is designed with a standardized form factor and unified appearance while incorporating the capability to control different types of HVAC equipment with varying power configurations. It includes adaptive control circuits that can handle different device specifications without requiring physically different control boxes, thus maintaining uniform appearance while preserving device-specific control capabilities.
4Ease of operation
If separated control boxes are used for each equipment, then basic control function is achieved, but monitoring and control linkage functions cannot be realized
Solution Approach 1:
The patent combines control functions, monitoring functions, and control linkage capabilities into a single integrated control device. It includes control circuits for basic device control, monitoring circuits for real-time status detection of all HVAC equipment, and control linkage circuits that coordinate operation between different devices (e.g., linking the operation of pumps with the air conditioner main machine). This integration achieves advanced functionality while maintaining ease of operation through a unified interface.
