Solution Overview

Problem

Existing translation means in lyophilization and sterilization machines are bulky, mechanically and electronically complex, require frequent maintenance, and pose dust and fume emission issues, particularly in pharmaceutical environments.

Innovation Solution

A device comprising limited feed means and pantograph mechanisms to efficiently move bottles from an arrival plane to a deposit plane within the treatment chamber, using pneumatic or mechanical pistons and motor-driven worm screws to facilitate compact, low-maintenance, and dust-free operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional translation means (pistons, motion feed cables, auxiliary translators) are used to move bottles from arrival plane to deposit plane, then the bottles can be translated into the treatment chamber, but the device becomes bulky, mechanically and electronically complex, requiring frequent maintenance and producing dust emissions

Engineering Contradiction:
Improvebottle translation capabilityVSAvoidmechanical and electronic complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces conventional mechanical translation means (pistons, cables, auxiliary translators) with a robotic arm system that uses motorized joints and control electronics to perform bottle translation. This substitution eliminates the need for complex mechanical linkages and motion feed cables, reducing mechanical complexity while maintaining translation capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The robotic arm is designed to perform multiple functions: it can translate bottles from the arrival plane to the deposit plane, extract bottles from the treatment chamber, and potentially handle different bottle configurations. This multi-functionality replaces what would traditionally require separate translation means, auxiliary thrust means, and extraction mechanisms, thereby reducing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If conventional translation means are used to translate rows of bottles onto the deposit plane, then the bottles can be loaded into the treatment chamber, but the device requires frequent maintenance and cleaning

Engineering Contradiction:
Improvebottle loading capabilityVSAvoidmaintenance frequency
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The robotic arm with motorized joints replaces mechanical components like pistons and motion feed cables that require frequent maintenance. The motorized system with enclosed joints and lack of external mechanical linkages reduces wear and tear, minimizing maintenance requirements while maintaining continuous bottle loading capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If conventional translation means are used to move bottles into the treatment chamber, then the bottles can be positioned on the deposit plane, but the device emits dust and fumes which is problematic in pharmaceutical environments

Engineering Contradiction:
Improvebottle translation capabilityVSAvoiddust and fume emissions
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The robotic arm system replaces mechanical translation means that generate dust through friction and wear. The motorized joints and controlled movement of the robotic arm eliminate the dust-generating mechanical interactions, while the lack of pneumatic systems eliminates fume emissions, making the system suitable for pharmaceutical environments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If auxiliary thrust means are added to enable complete translation of bottle rows onto the deposit plane, then all bottles can be loaded into the treatment chamber, but the device becomes even more bulky and complex

Engineering Contradiction:
Improvecomplete bottle row translationVSAvoiddevice bulk
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The robotic arm is designed with sufficient stroke length and positioning capability to perform the complete translation of bottle rows from the arrival plane to the deposit plane in a single operation. This eliminates the need for auxiliary thrust means that would add bulk, while the motorized system maintains control precision throughout the full range of motion.

Inventive Principle:
Principle #6Universality (Multi-functionality)
