Solution Overview

Problem

Current intraosseous access systems require multiple components that need assembly before use, which can be time-consuming and prone to loss or separation during transport, and occupy valuable space in limited environments.

Innovation Solution

A foldable and retractable intraosseous access system with a driver and integrated access assembly that can transition between folded and active states, allowing for a compact design and reducing assembly steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple separately packaged components are used, then the system can be more flexible and easier to manufacture, but the assembly time increases and components may be lost or separated during transport

Engineering Contradiction:
Improvecomponent manufacturing flexibilityVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent combines the driver and access assembly into a single integrated intraosseous access system. The access assembly is permanently attached to the driver, eliminating the need for separate packaging and manual assembly of multiple components. This integration directly reduces assembly time while maintaining manufacturing flexibility through modular design of the integrated unit.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If multiple separately packaged components are used, then each component can be optimized independently, but the risk of component loss or separation during transport increases

Engineering Contradiction:
Improvecomponent optimizationVSAvoidcomponent retention during transport
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

By integrating the access assembly with the driver into a single unit, the patent eliminates the risk of components being lost or separated during transport. The integrated design ensures all necessary components remain together throughout storage and transport, while still allowing independent optimization of each subsystem within the integrated architecture.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a non-foldable design is used, then the structure can be simpler and more robust, but the storage space requirements increase

Engineering Contradiction:
Improvestructural simplicityVSAvoidstorage space
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The patent implements a foldable access assembly that can transition between extended and retracted positions. When not in use, the access assembly folds against the driver, significantly reducing the overall volume of the system for storage and transport. The dynamic folding mechanism maintains structural integrity while enabling compact storage, resolving the contradiction between structural robustness and space efficiency.

Inventive Principle:
Principle #15Dynamics

4Productivity

If the access assembly is permanently extended, then immediate use is possible, but the storage and transport space requirements increase

Engineering Contradiction:
Improveimmediate usabilityVSAvoidstorage space
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The foldable access assembly allows the system to adapt its configuration based on usage state. During storage and transport, the assembly retracts to minimize volume. When needed, the assembly can be quickly extended to an operational position, providing immediate usability when required while maintaining compact form factor during non-use periods.

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments disclosed herein are directed to a retractable intraosseous access system configured to transition between an active state and one of a folded state or a retracted state. In the folded state, the access assembly can be pivoted relative to the driver to collapse the access assembly against a handle. In the retracted state, the access assembly is slidably received within a housing of the driver. Advantageously, the retractably intraosseous access system can provide an “all-in-one” design that does not require assembling separate components. Further the retractably intraosseous access system can provide a compact outer profile requiring reduced storage space.
