Solution Overview

Problem

Pharmaceutical order processing systems are labor-intensive and inefficient, particularly in high-volume settings, as they require substantial operator interaction to remove pharmaceuticals from small containers and transfer them to bulk storage, often involving multiple manufacturer containers for a single order.

Innovation Solution

A container disassembly workstation with a pharmaceutical receptacle assembly that includes a dust separation screen and receptacle, allowing for efficient separation and transfer of pharmaceuticals from small containers to larger bulk containers, reducing operator input and minimizing residual dust, with features like adjustable height and modular design for enhanced efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual container disassembly is used, then operator flexibility is maintained, but labor intensity and processing time increase significantly

Engineering Contradiction:
Improveprocessing throughputVSAvoidworkstation structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The workstation is divided into distinct functional modules: a container positioning module, a disassembly module with cutting mechanisms, a pharmaceutical transfer module with funnels, and a dust collection module. Each module handles a specific task independently, enabling automated high-throughput processing while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A dust separation screen is introduced as an intermediary component between the container disassembly zone and the pharmaceutical collection zone. This screen filters pharmaceutical dust from the stream of pharmaceuticals being transferred, preventing dust contamination while allowing efficient material flow, thus resolving the contradiction between automation speed and contamination control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If pharmaceuticals are transferred from small containers to bulk containers, then order fulfillment capability is improved, but pharmaceutical dust and residual contamination increase

Engineering Contradiction:
Improveorder fulfillment efficiencyVSAvoidpharmaceutical dust
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The dust separation screen serves as a critical intermediary that intercepts pharmaceutical dust particles while allowing bulk pharmaceuticals to pass through to the collection container. This resolves the contradiction by enabling high-volume transfer efficiency while simultaneously filtering out harmful dust contaminants.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The dust collection module extracts and removes pharmaceutical dust from the transfer stream separately from the main pharmaceutical flow. By taking out the harmful dust component, the system maintains high transfer efficiency while preventing dust contamination in the final bulk container.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple manufacturer containers must be emptied to fill a single order, then order flexibility is maintained, but processing time and labor requirements increase

Engineering Contradiction:
Improveorder customization capabilityVSAvoidprocessing cycle time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The workstation enables continuous operation through automated conveyor systems and coordinated module operation. Multiple manufacturer containers can be processed in sequence without interruption, with the dust separation screen and transfer mechanisms operating continuously to move pharmaceuticals from source containers to bulk containers, significantly reducing total processing time while maintaining order flexibility.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Manual mechanical operations of opening, emptying, and transferring containers are replaced with automated mechanisms including electronic cutters, funnel transfer systems, and conveyor belts. This substitution dramatically reduces processing cycle time for handling multiple manufacturer containers while preserving the ability to fulfill customized orders.

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

4Extent of automation

If automated container disassembly is implemented, then operator interaction is reduced, but initial system complexity and setup requirements increase

Engineering Contradiction:
Improveoperator interaction levelVSAvoidworkstation implementation
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The workstation is constructed as modular segments that can be independently manufactured, tested, and assembled. This segmentation makes the complex automated system easier to manufacture and implement, as each module can be produced using standard manufacturing processes and then integrated, reducing the overall implementation difficulty despite high automation levels.

Inventive Principle:
Principle #1Segmentation
