Modular Multi-Zone Temperature Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temperature controllers for hot runner injection molding processes are limited by their inability to efficiently manage multiple zones, requiring multiple standalone controllers for complex operations and large spaces, which complicates monitoring and calibration due to multiple interfaces and lack of expandability, portability, and flexible positioning.
Innovation Solution
A modular 6-zone hot runner temperature controller system that can be combined within a 24-zone capacity cabinet, daisy-chained to expand up to 192 zones, operated by a single Human-Machine Interface (HMI), and supports advanced features like energy conservation, thermocouple protection, and adaptive PID logic, allowing flexible installation and system-wide control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple standalone controllers are used to control multiple zones, then the number of controllable zones increases, but the device complexity and difficulty of monitoring/calibration increase due to multiple interfaces
Solution Approach 1:
The patent combines multiple zone controllers into a single integrated controller that can manage up to 24 zones through one unified interface. This consolidation eliminates the need for multiple separate controllers and interfaces, reducing system complexity while maintaining the ability to control a large number of zones. The single interface provides centralized monitoring and calibration capabilities for all zones.
Solution Approach 2:
The controller is designed as a universal multi-functional device that can control any combination of zones within its 24-zone capacity. It provides a single interface that handles multiple functions including temperature control, monitoring, calibration, and system-wide management, replacing the need for multiple specialized controllers.
2Length of stationary object
If multiple standalone controllers are used for large space coverage, then cable length is reduced, but the ease of operation deteriorates due to interaction with multiple interfaces
Solution Approach 1:
The patent merges multiple controller interfaces into a single unified interface that provides system-wide control and monitoring. This consolidation allows operators to monitor and calibrate all zones through one interface, significantly improving ease of operation compared to interacting with multiple separate controller interfaces.
3Adaptability or versatility
If modular controllers with fixed zone combinations are used, then expandability is limited, but the device complexity is reduced
Solution Approach 1:
The controller is designed with a modular architecture where zones are divided into banks of 6 zones each, with a total capacity of 24 zones. This segmentation allows for flexible configuration and expansion while maintaining a manageable single-interface control structure. The segmented design enables adaptability without proportionally increasing interface complexity.
Solution Approach 2:
The controller provides universal control capabilities for any combination of zones within its 24-zone capacity through a single interface. This multi-functional design allows the same controller to adapt to different configuration needs without requiring additional interfaces or controllers, enhancing expandability while controlling complexity.

AI summary
A scalable temperature controller has a single human interface that is connected to a cabinet that contains a plurality of identical control modules. One of the control modules is the master of other control modules in the cabinet and can access all interconnected control modules and allow user control of parameters therein through the human interface. Each control module has a processor that receives temperature information and controls heating elements. The scalable controller can connect and control additional control modules by connecting additional modules or cabinets without the need for an additional human interface.
