Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sterile packaging for implants lacks ease of handling and efficient stacking, leading to potential contamination risks and suboptimal space utilization.

Innovation Solution

A prism-shaped outer packaging with a container inside, featuring a first lid that opens by pulling and a second lid that tilts for easy removal, providing a double sterile barrier and allowing high packing density.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional sterile packaging is used, then the sterile object is protected, but the handling when opening is difficult and contamination risk increases

Engineering Contradiction:

Improvehandling when openingVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The packaging is divided into separate functional components: an outer packaging for protection and stacking, and an inner container with a lid that can be easily removed. This segmentation allows the outer packaging to remain intact while the inner container provides easy access, reducing contamination risk during opening.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner container with the sterile object is extracted as a separate removable unit from the outer packaging. The lid is designed to be pulled off easily, allowing quick access to the sterile object without compromising the integrity of the remaining packaging or increasing contamination risk.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If conventional packaging shapes are used, then manufacturing is simple, but stacking efficiency and space utilization are suboptimal

Engineering Contradiction:

Improvepacking density when stackingVSAvoidpackaging shape complexity

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The outer packaging employs an asymmetric prism shape with a triangular base, where the lateral faces have different dimensions. This asymmetric design optimizes stacking efficiency and space utilization while remaining manufacturable using standard forming processes for prismatic structures.

Inventive Principle:

Principle #4Asymmetry

3Reliability

If a simple single-layer container is used, then manufacturing is easy, but the sterile barrier protection is insufficient

Engineering Contradiction:

Improvesterile barrier protectionVSAvoidcontainer structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The packaging implements a nested structure where an inner container is placed within an outer packaging. Both layers provide sterile barrier protection, with the inner container holding the sterile object and the outer packaging providing additional protection and structural stability. This nested arrangement enhances reliability without excessive complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Sterile packaging for a sterile object (40) includes an outer packaging (1) and at least one container (10) arranged in the outer packaging (1) that forms a sterile barrier and in which a receiving compartment (13) is formed. The container (10) includes a first tray (15) closed by a peal-off first lid (14) and features a first recess in which the receiving compartment (13) is formed. The receiving compartment (13) is adapted to receive the sterile object (40) directly or indirectly. The outer packaging (1) features the form of a prism having two triangular or rectangular faces (1a, 1b), which are opposite each other along the longitudinal direction and which form a bottom face (1a) and a top face (1b) of the prism and also having three or four rectangular lateral faces (1c) forming a lateral surface area of the prism.
