Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional mechanical structures and conveyors are used for production flow changes, then the production line can maintain structural stability, but the reconfiguration becomes expensive and time-consuming

Engineering Contradiction:
Improveproduction flow change capabilityVSAvoidreconfiguration time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical conveyor structures with a magnetic field-based system. Carriers equipped with magnetic arrangements interact with magnetic fields generated by the transportation track to achieve movement, positioning, and engagement without mechanical contact. This substitution eliminates the need for manual mechanical reconfiguration while maintaining production line adaptability.

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

2Extent of automation

If dedicated cap applicator machines are used to attach capping devices, then the capping process can be automated, but the mechanical structure becomes complicated requiring careful alignment and adaptation

Engineering Contradiction:
Improvecapping device attachment automationVSAvoidmechanical structure complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical alignment and attachment mechanisms with magnetic field interactions. The magnetic arrangements on carriers and transportation tracks automatically guide and position capping devices onto containers without requiring complex mechanical alignment systems or dedicated cap applicator machines.

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

Solution Approach 2:

The magnetic transportation track system serves multiple functions: it transports carriers, positions capping devices, aligns components, and facilitates attachment - all within a single integrated system. This eliminates the need for separate dedicated machines for each function, reducing overall system complexity.

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

3Adaptability or versatility

If manual reconfiguration of mechanical structures is performed, then the production line can adapt to different products, but the production downtime increases

Engineering Contradiction:
Improveproduct change adaptabilityVSAvoidproduction output rate
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a dynamic magnetic field control system that can be reconfigured through software or control parameters rather than physical restructuring. The magnetic arrangements can be activated, deactivated, or repositioned electronically to adapt to different production requirements, enabling rapid product changes without stopping the production line.

Inventive Principle:
Principle #15Dynamics

AI summary

An apparatus is configured to implement, by a control device, a method for transporting containers (40) in a system for production of packaged food products. The apparatus arranges first items to be suspended from a conveyor (300), and arranges second items on support surfaces of carriers on a transportation track. The first items are capping devices (41) and the second items are containers (40), or vice versa. The apparatus further operates one of a first magnetic arrangement in the transportation track (200) and a second magnetic arrangement in the respective carrier (21) to move the respective carrier (21) on the transportation track (200) into a position beneath the conveyor (300) to align a second item on the respective carrier with a first item suspended by the conveyor), and controls the respective carrier (21) to move the support surface (25) towards the suspended conveyor (300) to engage the second item with the first item.
