Solution Overview

Problem

Existing medical device packaging fails to provide secure, unambiguous identification and communication of tool-specific data, leading to potential incorrect use and increased risk of patient safety issues due to insufficient documentation and handling limitations.

Innovation Solution

A package comprising a blister pack with a holding device and a readable data carrier, such as an RFID or NFC tag, that allows for automatic identification and communication of tool-specific data without compromising sterility, enabling easy recognition and safe handling of medical devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard packaging with labels is used for medical devices, then the packaging structure is simple and easy to manufacture, but the tool identification is unreliable and requires manual inspection

Engineering Contradiction:
Improvetool identification reliabilityVSAvoidpackaging structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the holding device and data carrier into an integrated unit that is sealed within the packaging. The data carrier is directly associated with the held tool, merging identification functionality with the physical containment structure, thereby improving reliability without proportionally increasing complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a data carrier as an intermediary element that bridges the tool and the packaging system. This intermediary stores tool-specific data and enables automatic identification, resolving the contradiction between simple packaging and reliable identification

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the tool is securely held in the packaging, then the tool protection is improved, but the tool becomes difficult or impossible to identify through the packaging

Engineering Contradiction:
Improvetool identification reliabilityVSAvoidtool identification ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual visual inspection of labels with automatic reading of data carriers. This substitution eliminates the need for users to physically examine packaging or interpret labels, allowing tool identification without compromising sterility or requiring manual intervention

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

Solution Approach 2:

The data carrier enables the tool to self-identify through automatic reading systems. The tool's identification data is actively available for reading without requiring user effort to locate or interpret labels, making the identification process effortless

Inventive Principle:
Principle #25Self-service

3Reliability

If labels with tool-specific data are attached to packaging, then information communication is possible, but the data may be contaminated or worn and is difficult to record accurately

Engineering Contradiction:
Improvedata accuracyVSAvoiddata contamination and wear
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The data carrier serves as a protected intermediary that stores tool-specific data in a controlled environment within the sealed packaging. This intermediary shields the data from external contaminants and wear that affect external labels, ensuring data accuracy throughout the tool's lifecycle

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent protects data from future contamination and wear by sealing the data carrier within the sterile packaging before use. This prior protection prevents data degradation that would otherwise occur with external labels exposed to environmental factors

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Productivity

If manual inspection and documentation of tool data is required, then no additional technology is needed, but the process is time-consuming and error-prone under surgical conditions

Engineering Contradiction:
Improvetool identification speedVSAvoididentification system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual inspection and documentation processes with automatic data reading of data carriers. This substitution eliminates time-consuming manual operations while integrating seamlessly into existing surgical workflows, improving productivity without requiring complex additional systems

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

Solution Approach 2:

The data carrier enables automatic self-identification of tools, eliminating the need for manual data recording by surgical staff. The system serves itself by providing readily readable data that can be automatically captured, freeing staff to focus on patient care

Inventive Principle:
Principle #25Self-service
