Solution Overview

Problem

Existing temperature control mechanisms for barrels in plastics and polymer processing are not easily removable or replaceable, and lack protection from damage and contamination, which can affect the flow characteristics of materials.

Innovation Solution

A modular heating and cooling band system that surrounds the barrel, composed of interconnected blocks with arcuate slots for removable temperature control mechanisms and a flexible cover for protection and temperature sensing, using insulating materials like vacuum cast ceramic fiber to maintain temperature control and prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional heating and cooling methods are used in extrusion processing, then temperature control is difficult and energy inefficient, but the patent introduces modular heating and cooling elements with sensors and controllers to achieve precise temperature control

Engineering Contradiction:
Improvetemperature control precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The heating and cooling system is divided into modular elements that can be independently controlled along the extrusion path. Each modular element includes its own heating capability, cooling capability, temperature sensor, and control logic, allowing localized temperature management without requiring complex centralized control systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each modular heating and cooling element is equipped with its own temperature sensor and control mechanism, enabling it to autonomously regulate its temperature based on feedback from the sensor. This self-regulating capability eliminates the need for complex external control systems while maintaining precise temperature control.

Inventive Principle:
Principle #25Self-service

2Loss of energy

If traditional heating and cooling systems are used, then energy efficiency is poor, but the patent implements localized modular elements that reduce energy consumption

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsystem structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

Instead of applying heating and cooling uniformly across the entire extrusion system, the patent implements modular heating and cooling elements at specific locations where temperature control is needed. This localized approach reduces energy consumption by avoiding unnecessary heating or cooling in regions where it is not required, while the modular structure manages the increased system complexity.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If uniform heating and cooling is applied throughout the extrusion system, then precise temperature control at different locations is difficult, but the patent uses modular elements to provide localized temperature management

Engineering Contradiction:
Improvetemperature uniformityVSAvoidlocalized temperature control
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system transitions from static, uniform heating and cooling to dynamic, localized temperature control. Each modular element can independently adjust its heating and cooling rates based on real-time temperature feedback from its sensor, allowing the system to adapt to varying thermal requirements at different locations along the extrusion path while maintaining overall temperature stability.

Inventive Principle:
Principle #15Dynamics

AI summary

An apparatus for controlling temperature of materials in a flowable state as they flow through a barrel. The apparatus includes a band surrounding the barrel having a plurality of connected blocks, each block having an inner surface in communication with the barrel. One or more of the connected blocks has a slot therein and has a removable, temperature controlling mechanism slidably received in the slot. A flexible cover surrounds an outer surface of the band with the flexible cover having a pouch for receiving a temperature sensing element.
