Solution Overview

Problem

Existing disposable containers for consumable products are either non-protective and environmentally unfriendly or protective but costly, failing to balance product safety and eco-friendliness, especially when consumers need to easily dispose of emptied containers.

Innovation Solution

A container design featuring a protective outer shell with a dispensing mechanism that allows for easy dispensing and ejection of cartridges, which can be reused while the emptied cartridges are discarded, using materials like plastic or metallic materials that protect against physical, water, heat, and dust damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a thin paper material container is used for disposable purposes, then ease of disposal and environmental friendliness are improved, but product protection capability deteriorates

Engineering Contradiction:
Improveease of disposalVSAvoidproduct protection capability
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The container is divided into two distinct parts: a durable reusable outer shell and a disposable inner cartridge. This segmentation allows the outer shell to provide continuous protection while the inner cartridge can be easily replaced and disposed of, resolving the contradiction between protection and ease of disposal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner cartridge is designed as a disposable component made of thinner, less expensive material that can be easily discarded after use. This allows the system to maintain high protection standards through the reusable outer shell while enabling easy and environmentally friendly disposal of the consumed product container.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Strength

If a more protective container is used, then product protection capability is improved, but manufacturing cost and environmental impact worsen

Engineering Contradiction:
Improveproduct protection capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

By segmenting the container into reusable and disposable parts, the system concentrates protection capabilities in the durable outer shell that can be manufactured once and reused multiple times, reducing overall manufacturing costs compared to making entirely protective disposable containers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer shell serves multiple functions across many uses: providing protection, housing the dispensing mechanism, and accommodating different inner cartridges. This multi-functionality justifies the higher initial manufacturing cost by spreading it across numerous reuse cycles.

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

3Strength

If a protective container is designed for reuse, then product protection is improved, but ease of disposal deteriorates

Engineering Contradiction:
Improveproduct protectionVSAvoidease of disposal
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The segmentation into reusable outer shell and disposable inner cartridge allows the protective function to be maintained through the durable outer shell while the inner cartridge provides easy disposal capability, eliminating the trade-off between protection and disposability.

Inventive Principle:
Principle #1Segmentation

4Reliability

If a recloseable dispensing mechanism is added to maintain freshness, then product freshness is improved, but device complexity worsens

Engineering Contradiction:
Improveproduct freshnessVSAvoidcontainer structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The dispensing mechanism is merged with the inner cartridge rather than being a separate complex system. The cartridge itself serves as both the product container and the dispensing mechanism, with the opening/closing function integrated into the cartridge design, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A container includes a cartridge containing a plurality of products therein. The cartridge defines a dispensing opening. The container also includes an outer shell configured to receive the cartridge therein. The outer shell includes a dispensing end and a receiving end. The receiving end is configured to receive the cartridge therethrough. The container further includes a dispensing mechanism coupled to the outer shell dispensing end. The dispensing mechanism is movable between a first position and a second position. The dispensing mechanism in the first position obstructs the dispensing opening such that the products are retained in the container, and the dispensing mechanism in the second position enables the products to be dispensed from the container.
