Problem

Existing equipment lacks the ability to adequately align and insert oriented objects, such as frusto-conical or cylindrical items, into the filter of tobacco products at high speeds, posing a manufacturing challenge.

Innovation Solution

A device comprising a frame with rotating singulation drums and air conveyance systems that align and insert objects into the filter, utilizing channels and pockets to ensure precise orientation and alignment with the filter segments, allowing for the insertion of oriented objects like frusto-conical or cylindrical items into the filter of tobacco products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional equipment is used to insert objects into filter rods, then the manufacturing process can proceed, but the objects cannot be adequately aligned with the filter at high speeds

Engineering Contradiction:
Improvealignment precision of objects with filterVSAvoidmanufacturing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The singulation drum pre-aligns objects in pockets before insertion, preparing them in the correct orientation and position ahead of time. This preliminary alignment action enables high-speed insertion while maintaining precision, as objects are already positioned correctly when the filter rod arrives.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The singulation drum acts as an intermediary device between the object supply and the filter rod insertion point. It receives objects, aligns them in oriented pockets, and delivers them precisely to the filter rod, mediating the transfer while ensuring both speed and alignment precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If high-speed insertion is implemented, then productivity increases, but alignment precision of objects with the filter deteriorates

Engineering Contradiction:
Improveinsertion speedVSAvoidalignment precision of objects with filter
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Objects are pre-aligned in the singulation drum pockets at high speed before the actual insertion. The alignment action is completed in advance during the drum rotation, allowing the insertion mechanism to simply transfer already-aligned objects, maintaining precision even at high speeds.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex mechanical alignment mechanisms with a rotating drum system that uses centrifugal force and gravity to naturally orient objects in pockets. This substitution simplifies the alignment process and enables high-speed operation while maintaining precision.

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

3Adaptability or versatility

If oriented objects are inserted into the filter, then the sensory attributes of cigarette smoke are enhanced, but the device complexity increases

Engineering Contradiction:
Improveability to insert oriented objectsVSAvoidcomplexity of alignment and insertion system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The insertion system is segmented into distinct functional components: object supply, singulation drum with oriented pockets, air conveyance system, and filter rod positioning. This segmentation allows each component to be optimized independently, managing complexity while enabling oriented object insertion capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The singulation drum serves multiple functions: it stores objects in oriented pockets, aligns them during rotation, and delivers them to the filter rod. This multi-functionality reduces the need for separate alignment mechanisms, managing device complexity while providing the adaptability to insert oriented objects.

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