Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning beams require high technical effort and space for heating, are not environmentally friendly, and consume energy unnecessarily due to uniform temperature requirements and complex heating systems, making them costly and difficult to expand modularly.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional heating media (oil or Dyphyl) are used in the heating circuit, then the spinning beam can maintain temperature, but the system becomes complex and requires vacuum stations, heating systems, high-temperature boilers, and pressure vessels
Solution Approach 1:
The patent extracts and eliminates the complex heating medium (oil or Dyphyl) from the system by using electric heating elements directly embedded in the nozzle throat and distribution block. This removes the need for vacuum stations, boilers, and pressure vessels while maintaining temperature control capability.
Solution Approach 2:
The patent replaces the mechanical/chemical heating system (boilers, pipes, heating media) with an electrical heating system. Electric heating elements are embedded directly in the components, substituting the complex thermal fluid system with a simpler electrical system that achieves the same temperature maintenance function.
2Temperature
If uniform temperature level is maintained across all components, then the liquid plastic is advantageous, but unnecessary energy is consumed for individual components that do not require variable temperature adjustment
Solution Approach 1:
The patent implements local quality by providing independent temperature control for different components (nozzle throat and distribution block) through separate electric heating elements. Each component can be heated to its specific required temperature rather than maintaining uniform temperature across all components, reducing energy waste in components that do not require high temperature.
Solution Approach 2:
The patent enables dynamic temperature adjustment for individual components based on actual process needs. The electric heating elements can be independently controlled to provide variable temperature levels to different parts of the spinning beam, allowing the system to adapt temperature requirements dynamically rather than maintaining static uniform temperature.
3Temperature
If traditional heating systems with boilers and pressure vessels are used, then heating can be provided, but the system is not environmentally friendly and handling is critical for safety reasons
Solution Approach 1:
The patent removes hazardous heating media (oil or Dyphyl) and their associated infrastructure (boilers, pressure vessels) from the system. By using electric heating elements with no moving parts or hazardous fluids, the system eliminates the environmental and safety hazards inherent in traditional heating systems.
Solution Approach 2:
The patent replaces the mechanical heating system with hazardous fluids and high-pressure components with a electrical heating system. Electric heating elements provide the same heating function without the environmental pollution, safety risks, and complex infrastructure of traditional boiler-based systems.
4Productivity
If the spinning beam is enlarged, then production capacity increases, but the heating system must be replaced or expanded modularly which increases complexity and cost
Solution Approach 1:
The patent segments the heating system into independent, modular electric heating elements that can be individually added or removed. Each heating element is embedded in specific components (nozzle throat, distribution block) and can be independently controlled, allowing easy modular expansion when production capacity needs to increase without redesigning the entire heating system.
