Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual format change systems are used for lid displacement, then the system structure is simple, but the execution time is long and productivity is low

Engineering Contradiction:
Improveexecution speed of format changeVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the gearwheels adjustable in their separation distance. The system transitions from a static configuration to a dynamic one where the distance between gearwheels can be modified to accommodate different lid formats. This is achieved through adjustable mounting mechanisms that allow the gearwheels to be repositioned along the chains, enabling quick adaptation to various lid sizes and shapes without complete system reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing the separation distance between gearwheels to be varied. This parameter adjustment enables the system to handle different lid formats efficiently. The gearwheels can be positioned at different distances from each other based on the specific lid dimensions, thus optimizing the displacement process for each format while maintaining a relatively simple overall system structure.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If fixed separation distance between gearwheels is used, then the device structure is simple, but the adaptability to different lid formats is poor

Engineering Contradiction:
Improvecompatibility with different lid formatsVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs dynamic adjustability where the separation distance between gearwheels can be modified based on the lid format requirements. The gearwheels are mounted on adjustable supports that allow them to be repositioned along the chain path, enabling the same system to accommodate various lid sizes and shapes without requiring multiple dedicated systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent achieves universality by designing a single displacement system that can handle multiple lid formats through adjustable gearwheel positioning. The chains and gearwheels serve multiple functions by being reconfigurable, allowing the same mechanical components to adapt to different production requirements, thus eliminating the need for separate systems for each lid format.

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

3Loss of time

If manual adjustment of gearwheel positions is used, then the device structure is simple, but the downtime during format change is long

Engineering Contradiction:
Improvedowntime during format changeVSAvoidease of format change execution
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system enables dynamic reconfiguration of gearwheel positions during operation. The adjustable mounting mechanisms allow operators to quickly modify the separation distance between gearwheels to match different lid formats, significantly reducing the downtime associated with format changes while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by pre-positioning the gearwheels on adjustable supports that allow for quick reconfiguration. The adjustment mechanisms are designed to enable operators to rapidly change the gearwheel separation distance to the required position for the next lid format, minimizing idle time between production runs.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If chains with fixed gearwheel separation are used, then the manufacturing cost is low, but the installation costs and downtime for format changes are high

Engineering Contradiction:
Improveinstallation cost and downtimeVSAvoidchain and gearwheel system complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies dynamics by incorporating adjustable mounting mechanisms for the gearwheels on the chains. This allows the separation distance to be modified without replacing entire chain assemblies, thereby reducing installation costs and downtime for format changes while maintaining a relatively simple chain and gearwheel system structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses preliminary action by pre-configuring the chains with adjustable gearwheel mounts that can be quickly repositioned. This preliminary design feature enables rapid format changes without requiring costly reinstallation or complex reconfiguration procedures, thus lowering both installation costs and downtime.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to an adjustable system for displacing multi-format lids (4), comprising a drive mechanism which in turn comprises an upper rotation system with two upper gearwheels (5a, 5b), parallel and separated by a length, in a first transverse direction, a lower rotation system with two lower gearwheels (6a, 6b); also parallel and separated by a length, in the same first transverse direction; a first chain (1a) geared to a first upper gearwheel (5a) and to a first lower gearwheel (6a); a second chain (1b) geared to a second upper gearwheel (5b) and to a second lower gearwheel (6b) and a chassis (10) on which the rotation systems are mounted. The first chain (1a) and the second chain (1b) transmit the rotation between the gearwheels (5a, 5b, 6a, 6b). The first chain (1a) and the second chain (1b) comprise lid fastening means (4) for holding the lids (4) during the displacement thereof. The adjustable system also comprises a first transverse adjustment mechanism configured to modify the separation length between the first gearwheels (5a, 6a) and the second gearwheels (5b, 6b), as well as between the first chain (1a) and the second chain (1b), within a range comprising a first end having a greater length and a second end having a shorter length.
