Solution Overview

Problem

Existing automatic packaging systems for compressible tubes, such as cosmetic tubes, are inefficient in terms of speed and space utilization when packaging tubes vertically in cardboard boxes.

Innovation Solution

An automatic packaging installation that includes a first polyarticulated system to grip and place tubes flat on an intermediate plate with wedges, and a second polyarticulated system to simultaneously grip and package the tubes flat in a package, reducing space requirements and optimizing execution speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If tubes are packaged vertically in cardboard boxes using conventional polyarticulated systems, then the packaging structure is simple, but the space requirement is large and the execution speed is slow

Engineering Contradiction:
Improvespace requirementVSAvoidpackaging system complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent transitions from vertical packaging (one dimension) to flat horizontal packaging (another dimension). Tubes are placed flat on intermediate plates and then packaged horizontally in cardboard boxes,充分利用 the horizontal space and reducing the vertical height requirement, thereby significantly reducing the overall space requirement by a factor of three

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces intermediate plates with wedges as a preliminary packaging stage. Tubes are first arranged flat on these intermediate plates with precise positioning, then the entire plate with all tubes is transferred at once to the final packaging. This preliminary organization enables efficient bulk handling and reduces the complexity of direct individual tube packaging

Inventive Principle:
Principle #10Preliminary action

2Productivity

If tubes are packaged vertically one by one, then the packaging structure is simple, but the speed of execution is slow

Engineering Contradiction:
Improvespeed of executionVSAvoidpackaging system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple tubes onto a single intermediate plate, organizing several tubes in a coordinated arrangement. The polyarticulated system then transfers the entire group of tubes simultaneously from the plate to the packaging, converting individual tube operations into batch operations and significantly increasing execution speed

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The intermediate plate acts as a mediator between the tube supply and the final packaging. It provides a stable platform for organizing tubes in advance, allowing the polyarticulated system to pick up and place multiple tubes as a single unit, thereby improving productivity without requiring complex direct manipulation of each tube

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If tubes are packaged flat with tiling arrangement, then the space requirement is reduced by a factor of three, but the positioning precision requirement increases

Engineering Contradiction:
Improvespace requirementVSAvoidpositioning precision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The patent applies localized geometric features (wedges with specific angles and shapes) at critical contact points on the intermediate plate. These wedges are precisely shaped to match the tube cross-sections, providing automatic self-positioning and ensuring high positioning precision only where needed, rather than requiring precision throughout the entire system

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs asymmetric wedge shapes with specific angle variations (e.g., 45°, 30°, 15°) that create unique positioning geometries for each tube location. This asymmetric design ensures that tubes can only be placed in the correct orientation and position, achieving high positioning precision through geometric constraint rather than complex control mechanisms

Inventive Principle:
Principle #4Asymmetry
