Solution Overview

Problem

Sterilization wraps often require bonding two sheets for enhanced sterility, increasing manufacturing costs and effort, and small punctures can be difficult to detect, potentially allowing contaminants to reach sterilized items.

Innovation Solution

Sterilization wraps with contrasting colors on opposing sides are used in pairs, either un-bonded or coupled, to ensure proper usage and detect small holes, reducing manufacturing costs and improving sterility assurance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two sterilization wraps are bonded together to ensure proper usage, then the reliability of sterilization is improved, but the manufacturing cost and complexity increase

Engineering Contradiction:
Improvesterilization assuranceVSAvoidmanufacturing process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sterilization wrap is designed with different colors on opposite sides (e.g., blue on one side, white on the other). This color differentiation provides visual feedback to users to ensure proper double-wrap usage without requiring bonding mechanisms, thereby maintaining reliability while simplifying manufacturing

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The wrap itself provides the guidance mechanism through its color-coded design. The colored sides act as built-in instructions that guide proper usage without external bonding or complex assembly requirements, making the system self-explanatory and easier to manufacture

Inventive Principle:
Principle #25Self-service

2Reliability

If two sterilization wraps are bonded together to prevent single-wrap usage, then the reliability is improved, but the manufacturing time and effort increase

Engineering Contradiction:
Improvesterilization assuranceVSAvoidmanufacturing cycle time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Different colors on opposite sides of the wrap provide immediate visual confirmation of proper usage. This eliminates the need for bonding processes, ultrasonic welding, or other time-consuming connection methods, thereby improving manufacturing productivity while maintaining sterilization reliability

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The mechanical bonding system (ultrasonic welding, adhesive bonding) is replaced with an optical information system (color coding). This substitution eliminates complex manufacturing steps while providing equivalent or superior guidance functionality

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If a single thick sterilization wrap is used instead of multiple sheets, then the manufacturing process is simplified, but the ability to detect small punctures is reduced

Engineering Contradiction:
Improvewrap productionVSAvoidpuncture detection
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The wrap uses contrasting colors on opposite sides, which enhance the visibility of small punctures and defects. When light passes through or reflects off the colored layers, even minor holes become more apparent, improving detection capability while maintaining the simplicity of a single-wrap design

Inventive Principle:
Principle #32Color changes

AI summary

Sterilization wraps have a first side colored at least a first color and an opposing second side colored at least a second color that is different than the first color. These sterilization wraps are then paired such that each of the pairs of sterilization wraps has the aforementioned first sides of the sterilization wraps that comprise the pair of sterilization wraps facing one another. By one approach these pairs of sterilization wraps are un-bonded and hence are not physically connected to one another. By another approach the sterilization wraps that comprise a given pair can be coupled to one another (for example, by an intermingling of the materials that comprise the two sterilization wraps). A plurality of such pairs of sterilization wraps can then be placed in a suitable container to facilitate handling, storage, and shipment.
