Solution Overview

Problem

Current methods for manufacturing beverage capsules from biodegradable materials are not suitable due to the low heat resistance of these materials, which causes them to melt or degrade during the shaping process, especially at the high speeds required in production.

Innovation Solution

A preheating apparatus that uses a housing with airflow passages to uniformly heat the material, providing a substantially uniform temperature distribution across the defined areas, allowing for quick and efficient heating of biodegradable materials without melting, using heated air streams and airflow disrupters to ensure consistent temperature across the material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If heated air is applied to shape biodegradable material quickly, then productivity is improved, but the material melts or degrades due to excessive heat

Engineering Contradiction:
Improveproduction speedVSAvoidmaterial degradation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies different temperature zones to different areas of the material. The airflow passages deliver heated air at controlled temperatures to specific defined areas, allowing localized heating that is sufficient for shaping without exceeding the material's thermal tolerance and causing degradation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The material is preheated to a controlled temperature before the shaping process begins. This preliminary heating prepares the biodegradable material for forming without subjecting it to excessive heat, enabling subsequent shaping while maintaining material integrity.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If uniform temperature distribution is achieved across the material, then manufacturing precision is improved, but device complexity increases due to airflow disrupters

Engineering Contradiction:
Improvetemperature uniformityVSAvoidapparatus structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Airflow disrupters are introduced as intermediary elements within the airflow passages. These disrupters modify the heated air flow to eliminate temperature gradients and ensure uniform heat distribution across the material surface, achieving precise temperature control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Temperature

If heated air is applied to biodegradable material, then the material can be shaped, but the material melts due to low heat resistance

Engineering Contradiction:
Improveheating temperatureVSAvoidmaterial integrity
Core Design Contradiction:
TemperatureVSStability of the object's composition

Solution Approach 1:

The patent carefully controls the temperature parameter of the heated air applied to the biodegradable material. By maintaining the temperature within a specific range (above glass transition but below melting point), the material becomes sufficiently pliable for shaping while retaining its structural integrity and preventing melting.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If high speed production is maintained, then productivity is improved, but the material degrades due to insufficient cooling time

Engineering Contradiction:
Improveproduction cycle timeVSAvoidmaterial quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The heating and shaping processes are conducted in continuous sequence without interruption. The material flows continuously through the heating zones and shaping zones, maintaining optimal temperature throughout the process and eliminating idle time that would cause cooling and potential quality issues, thereby enabling high-speed production while preserving material integrity.

Inventive Principle:
Principle #20Continuity of useful action
