Solution Overview

Problem

Existing container systems lack an efficient and reusable solution for packaging and storing consumer goods, as they often require complex resealing mechanisms and do not facilitate easy removal and replacement of liners.

Innovation Solution

A container system comprising a body with a recess and a cap, along with a disposable cartridge having an outer and inner liner. The cartridge is designed to be removably inserted into the container, with the inner liner being flexible and heat-resistant, allowing it to be turned inside out for easy removal and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a reusable container system is used, then the container can be reused for multiple purposes, but complex resealing mechanisms are required

Engineering Contradiction:

ImprovereusabilityVSAvoidresealing mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container system is divided into separate functional components: a reusable container body and a disposable cartridge assembly. The cartridge contains the inner liner, outer liner, and seal as separate segments that can be easily assembled and replaced, eliminating the need for complex resealing mechanisms while maintaining reusability of the container body.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cartridge assembly including inner liner, outer liner, and seal is designed as a disposable component that is replaced rather than reused. This eliminates the need for complex resealing mechanisms while maintaining the reusability of the container body, as the disposable cartridge is simply inserted and removed without requiring sealing operations.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If a disposable liner is used, then hygiene is ensured, but the liner cannot be reused

Engineering Contradiction:

ImprovehygieneVSAvoidreusability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments the liner into an inner liner and outer liner that work together as a disposable unit. The inner liner contacts the product and can be turned inside out for cleaning, while the outer liner provides structural support and sealing. This segmented design maintains hygiene through easy cleaning while enabling reuse of the container body with fresh cartridges.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner liner is designed to be turned inside out and cleaned rather than discarded, allowing recovery and reuse. The outer liner and seal are discarded with the inner liner after use, maintaining hygiene standards while enabling continued use of the container body with fresh disposable cartridges.

Inventive Principle:

Principle #34Discarding and recovering

3Strength

If a rigid liner is used, then structural integrity is maintained, but the liner cannot be turned inside out for easy removal

Engineering Contradiction:

Improvestructural integrityVSAvoidremoval and replacement

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The liner system applies different material properties to different parts: the inner liner uses flexible material that can be turned inside out for easy removal and cleaning, while the outer liner uses more rigid material that maintains structural integrity during use. This local differentiation of material qualities resolves the contradiction between rigidity and ease of removal.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The inner liner is designed with flexible properties that allow it to be turned inside out dynamically during the removal process. This dynamic flexibility enables easy access to the inner surface for cleaning while the outer liner maintains structural integrity during normal use, resolving the contradiction between rigidity and ease of operation.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If a simple liner structure is used, then manufacturing is easy, but the liner cannot provide effective sealing

Engineering Contradiction:

Improveliner structureVSAvoidsealing

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The sealing function is segmented into a dedicated seal component that attaches to the outer liner, separating the sealing function from the structural liner components. This segmented approach maintains ease of manufacture for each individual component while achieving effective sealing through the specialized seal that interfaces with the container body.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The seal acts as an intermediary component between the disposable cartridge and the reusable container body. This intermediate sealing element provides effective sealing while allowing for easy assembly and disassembly of the cartridge, maintaining both manufacturing simplicity and sealing reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)
