Solution Overview

Problem

Conventional peritoneal dialysis kits generate excessive medical waste and have high sterilization costs due to inefficient packaging, which increases the overall cost of treatment for patients.

Innovation Solution

A kit design that incorporates an overwrap which reduces packaging material consumption and enhances heat penetration during sterilization by integrating the drainage bag as a portion of the overwrap, thereby minimizing waste and lowering manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional packaging materials are used for peritoneal dialysis kits, then the bags are adequately protected, but excessive packaging material is consumed generating medical waste

Engineering Contradiction:

Improvepackaging material consumptionVSAvoidprotection of bags

Core Design Contradiction:

Loss of substanceVSReliability

Solution Approach 1:

The drainage bag is integrated with the overwrap to form a unified structure. The overwrap acts as both packaging material and structural component of the drainage bag, eliminating the need for separate packaging materials and reducing medical waste while maintaining protective function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The overwrap serves multiple functions: it protects the bags during storage and transport, acts as a structural component of the drainage bag, and provides sterilization barrier. This multi-functionality reduces the need for additional separate components and materials

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Use of energy by stationary object

If conventional packaging is used for peritoneal dialysis kits, then the bags are adequately protected, but sterilization costs increase due to poor heat penetration

Engineering Contradiction:

Improvesterilization costVSAvoidprotection of bags

Core Design Contradiction:

Use of energy by stationary objectVSReliability

Solution Approach 1:

By integrating the drainage bag with the overwrap, the packaging structure becomes thinner and more uniform, allowing heat to penetrate more efficiently during sterilization. This reduces sterilization time and energy consumption while maintaining adequate protection through the integrated structure

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If conventional packaging materials are used, then adequate protection is provided, but the overall treatment cost increases

Engineering Contradiction:

Improvemanufacturing costVSAvoidprotection of bags

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The integration of drainage bag and overwrap into a single structure reduces material costs and manufacturing complexity. The unified structure requires fewer assembly steps and less material while providing equivalent or superior protection compared to conventional separate packaging

Inventive Principle:

Principle #5Merging (Combining)
