Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If containers with non-circular cross-sections are produced using special blow molding machines, then the container shape is achieved, but alignment problems occur during labeling and filling operations

Engineering Contradiction:
Improvecontainer cross-section shapeVSAvoidalignment during labeling and filling
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The transport device performs preliminary alignment of containers with non-circular cross-sections before they reach labeling and filling machines. The device includes alignment elements that detect the orientation of the container and rotate it to the correct position, ensuring proper alignment for subsequent operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A dedicated transport device acts as an intermediary between the blow molding machine and the labeling/filling machines. This intermediate device corrects alignment issues that arise during container production, enabling smooth operation of downstream equipment without requiring modifications to the containers themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If steep guide curves are used for container transfer, then transfer speed is improved, but container twisting and jamming occur

Engineering Contradiction:
Improvecontainer transfer speedVSAvoidcontainer twisting and jamming
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The transport device uses dynamic, adjustable guide curves that can adapt to different container types and transfer conditions. The guide curves are designed to be gentler and more gradual, reducing mechanical stress on containers while maintaining efficient transfer speeds through optimized motion paths.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system modifies transfer parameters such as guide curve geometry, transfer angle, and speed profiles to eliminate container twisting and jamming. By changing these parameters, the system achieves high-speed transfer without the harmful effects associated with steep, rigid guide curves.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If high production speeds are achieved, then productivity increases, but alignment precision and handling reliability decrease

Engineering Contradiction:
Improveproduction speedVSAvoidalignment precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The transport device incorporates sensors and detection systems that monitor container position and orientation in real-time. This feedback enables continuous adjustment of alignment parameters, ensuring high precision even at elevated production speeds. The system can detect and correct misalignment automatically, maintaining quality standards throughout high-speed operation.

Inventive Principle:
Principle #23Feedback
