Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual processing of reusable containers is used, then operation simplicity is maintained, but labor cost increases and processing efficiency decreases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic container processing system is divided into distinct functional modules: loading module for receiving containers, washing module for cleaning, drying module for removing moisture, and stacking module for organized storage. Each module performs a specific task independently, allowing the system to achieve high automation and productivity while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If disposable containers are used, then convenience is improved, but material waste increases and environmental pollution worsens

Engineering Contradiction:
ImproveconvenienceVSAvoidmaterial waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The system enables reusable containers to serve themselves through automated processing. Containers are automatically loaded, washed, dried, and stacked without requiring manual intervention for each container. This self-service approach maintains the convenience of disposable containers while eliminating the environmental harm by enabling repeated use of durable containers.

Inventive Principle:
Principle #25Self-service

3Productivity

If automatic processing system is implemented, then labor cost decreases and processing efficiency improves, but device complexity increases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic processing system is designed with multi-functional modules that can handle various types of reusable containers. The loading module, washing module, drying module, and stacking module are configured to accommodate different container shapes, sizes, and materials, allowing the system to maintain high productivity across diverse container types while avoiding the need for multiple specialized systems.

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