Solution Overview

Problem

Conventional tip packages are resource-intensive, generating significant plastic waste and are difficult to recycle due to their solid structure, which also poses challenges in sterilization and contamination prevention.

Innovation Solution

A box-shaped tip package design featuring a rigid frame with openings covered by thin film material, such as breathable paper-based materials like Tyvek, which reduces plastic usage, enhances sterilization access, and allows for easier recycling by being collapsible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional solid plastic tip packages are used, then structural strength and contamination prevention are improved, but plastic waste and recycling difficulty increase

Engineering Contradiction:
Improvestructural strengthVSAvoidplastic waste
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The tip package is segmented into two distinct parts: a rigid plastic frame providing structural strength and a separate thin film material covering the openings for contamination prevention. This segmentation allows the thin film to be removed and recycled separately from the frame, reducing overall plastic waste while maintaining the necessary structural integrity during use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tip package employs a composite structure combining rigid plastic (for strength) with thin film material (for contamination barrier). This composite approach allows each material to perform its optimal function - the plastic frame withstands picking forces while the thin film prevents contamination, and enables easier separation for recycling purposes.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If conventional solid plastic tip packages are used, then structural integrity is improved, but packaging volume for recycling increases

Engineering Contradiction:
Improvestructural integrityVSAvoidpackaging volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

By segmenting the package into a rigid frame and a removable thin film covering, the thin film can be detached and compressed into a much smaller volume for recycling, while the rigid frame maintains its structural integrity during the entire process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The thin film material covering the openings can be flexibly removed and compressed to a minimal volume, unlike solid plastic packages that maintain their box shape. This flexible film structure allows for dramatically reduced packaging volume during recycling while the rigid frame remains intact.

Inventive Principle:
Principle #30Flexible shells and thin films

3Quantity of substance

If thin film material is used to cover openings, then plastic usage is reduced, but resistance to picking forces may be compromised

Engineering Contradiction:
Improveplastic usageVSAvoidresistance to picking forces
Core Design Contradiction:
Quantity of substanceVSForce

Solution Approach 1:

The force-bearing function is segmented to be handled exclusively by the rigid plastic frame, while the thin film material handles only the contamination barrier function. This segmentation allows significant reduction in plastic usage for the film covering while the frame maintains full resistance to picking forces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The thin film material is used only for covering openings to prevent contamination, not for bearing forces. This application of thin film technology reduces plastic usage significantly while the rigid frame structure independently provides the necessary resistance to picking forces.

Inventive Principle:
Principle #30Flexible shells and thin films
