Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If specialized manufacturing machines are used to produce complex-shaped containers, then the container shape complexity is improved, but the manufacturing cost and machine downtime increase

Engineering Contradiction:
Improvecontainer shape complexityVSAvoidmanufacturing machine complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-forming ablation areas and ablated lines on the blank before the main forming process. These pre-prepared features enable the blank to automatically deform into complex three-dimensional shapes during normal high-speed manufacturing, eliminating the need for specialized deformation devices while achieving complex container shapes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention enables self-service by designing the blank with ablation areas and ablated lines that allow the material itself to deform into complex shapes under normal folding forces during assembly. The blank serves its own shaping function without requiring external specialized equipment, thus avoiding increased device complexity while achieving complex container geometries.

Inventive Principle:
Principle #25Self-service

2Shape

If specialized deformation devices are used to modify container walls after assembly, then the container shape is improved, but the process complexity and time consumption increase

Engineering Contradiction:
Improvecontainer wall shapeVSAvoidmanufacturing efficiency
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-forming ablation areas and ablated lines on the blank before assembly. This ensures that the complex wall shapes are achieved during the normal high-speed assembly process, eliminating the need for post-assembly deformation operations and maintaining high productivity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of deforming the container walls after assembly as in conventional methods, the invention inverts the sequence by pre-preparing the blank with ablation features that enable automatic deformation during assembly. This reversal of the process sequence eliminates post-assembly deformation steps and maintains manufacturing efficiency.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 1:

The patent applies preliminary action by pre-forming ablation areas and ablated lines on the blank using existing high-speed manufacturing equipment. This preliminary preparation enables the blank to automatically deform into complex three-dimensional shapes during normal assembly, allowing existing machines to produce complex container shapes without major modifications while maintaining cost-effectiveness.

Solution Approach 1:

The patent applies local quality by strategically positioning ablation areas and ablated lines in specific locations on the blank where they will create the desired three-dimensional wall shapes upon deformation. The ablated lines are configured to extend across the inner surface in patterns that achieve complex geometries while maintaining adequate structural integrity in critical load-bearing areas.
