Solution Overview

Problem

The manual transfer of solid raw materials from original containers to process mixers leads to uncontrollable dusting, health hazards, and the risk of flammable hybrid mixtures, along with logistical complexities and costs associated with storing and handling broached containers.

Innovation Solution

A robotic refilling and transferring unit that captures original containers, cuts them open dust-free, and transfers solid raw materials into standardized loading units, which can be connected to a process mixer using an active gas stream to prevent flammable vapors from entering the transfer zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual transfer of solid raw materials is used, then operational simplicity is maintained, but dusting and health hazards increase

Engineering Contradiction:
Improvemanual operation simplicityVSAvoiddusting and health hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical handling with an automated robotic system that uses a robotic arm to capture original containers, position them on a cutting means, and transfer materials through controlled openings. This substitution eliminates direct human exposure to dust while maintaining operational efficiency through automation.

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

Solution Approach 2:

The patent creates a controlled environment by equipping the robotic unit with covering means that can close openings during cutting and transfer operations. This containment approach prevents dust from escaping into the working area, effectively creating a protected zone that safeguards workers from health hazards.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Reliability

If original containers are broached and stored pending further use, then material availability is ensured, but storage costs and logistical complexity increase

Engineering Contradiction:
Improvematerial availabilityVSAvoidstorage and handling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by completely emptying original containers into the robotic unit before returning them to storage. The container is positioned, opened, emptied, and then the opening is closed before the container is returned to the pallet. This ensures that returned containers are ready for future use without requiring intermediate storage of partially used materials.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the handling process into distinct phases: capture of original container, positioning on cutting means, controlled emptying through openings, and return to storage. This segmentation allows each phase to be optimized independently, ensuring complete emptying while simplifying storage requirements for returned containers.

Inventive Principle:
Principle #1Segmentation

3Productivity

If piping systems connect transfer vessels to process mixers, then material transfer is enabled, but flammable vapor transfer risk increases

Engineering Contradiction:
Improvematerial transfer efficiencyVSAvoidflammable vapor transfer risk
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful element (flammable vapors) from the transfer process by using a robotic unit with covered openings. The covering means prevents vapors from escaping during material transfer, and the robotic arm operates in a controlled manner that minimizes vapor release into the working area, thereby eliminating the fire hazard associated with traditional open piping systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The robotic unit acts as an intermediary between the original containers and the process mixer. Instead of direct piping connections that allow vapor transfer, the robotic system provides a controlled interface with coverable openings, serving as a barrier that prevents flammable vapors from reaching the mixer while still enabling efficient material transfer.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Speed

If central stores open raw material units on-site, then access speed is improved, but safety provision requirements and logistical costs increase

Engineering Contradiction:
Improvematerial access speedVSAvoidsafety and logistical requirements
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The robotic unit performs the opening and emptying operations autonomously without requiring human intervention or special safety provisions at the central store location. The automated system captures containers from pallets, opens them using integrated cutting means, and transfers materials back to storage, enabling rapid access while eliminating the need for additional safety infrastructure or specialized handling procedures.

Inventive Principle:
Principle #25Self-service
