Solution Overview

Problem

Conventional sealing apparatuses require replacement of cartridges with different sizes to accommodate sealing sheets of varying bottle openings, leading to inconvenience and increased costs due to the need for multiple cartridges.

Innovation Solution

A diameter variable type cartridge with rotatable guide bars that adjust the spacing between guide bars to accommodate sealing sheets of different diameters, eliminating the need for cartridge replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cartridges of different sizes are prepared to accommodate sealing sheets of various diameters, then the sealing apparatus can handle different bottle sizes, but the device complexity and storage requirements increase

Engineering Contradiction:

Improveability to handle different sealing sheet sizesVSAvoidnumber of cartridges to be prepared and stored

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cartridge incorporates movable guide bars that can be adjusted radially to change the internal diameter of the cartridge. This dynamic adjustment mechanism allows a single cartridge to adapt to different sealing sheet sizes by moving the guide bars closer together or farther apart, eliminating the need for multiple fixed-size cartridges

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cartridge's internal diameter parameter is made variable through the adjustable guide bar mechanism. By changing the radial position of the guide bars, the effective diameter of the cartridge changes to match different sealing sheet diameters, providing versatility without requiring multiple cartridges with different fixed parameters

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If cartridges are replaced according to sealing sheet size, then the correct size is accommodated, but operational time and convenience are reduced

Engineering Contradiction:

Improvematching cartridge size to sealing sheet sizeVSAvoidtime required for cartridge replacement operations

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The adjustable guide bar mechanism enables dynamic reconfiguration of the cartridge diameter during operation. Instead of replacing cartridges, the operator can simply adjust the guide bars to the appropriate position, significantly reducing the time and effort required to change between different sealing sheet sizes

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple types of cartridges are maintained for different sealing sheet sizes, then all bottle sizes can be accommodated, but storage space and device costs increase

Engineering Contradiction:

Improvecoverage of all bottle sizesVSAvoidstorage space required for multiple cartridges

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The cartridge is designed as a universal, multi-functional unit that can accommodate multiple sealing sheet sizes through the adjustable guide bar mechanism. This single cartridge performs the function of what would otherwise require multiple specialized cartridges, eliminating the need for additional storage space and reducing overall device costs

Inventive Principle:

Principle #6Universality (Multi-functionality)
