Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual needle insertion is used, then flexibility is maintained, but insertion precision and consistency deteriorate

Engineering Contradiction:

Improveneedle insertion precisionVSAvoidguiding system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a guiding track as an intermediary component between the needle block assembly and the patient's arm. This track provides a predetermined path that guides the needle to the exact insertion point, eliminating the need for manual positioning while maintaining system simplicity through its straightforward rail-like structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The guiding track is pre-configured with a specific geometric path that determines the needle insertion trajectory before the procedure begins. This preliminary setup ensures that when the needle block assembly moves along the track, the insertion precision is automatically achieved without requiring real-time adjustment or complex control mechanisms.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If traditional IV insertion methods are used, then procedural time is reduced, but reliability and consistency of insertion deteriorate

Engineering Contradiction:

Improveinsertion reliabilityVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the insertion process into distinct functional components: a compression sleeve for vein stabilization, a guiding track for path definition, and a needle block assembly for needle delivery. This segmentation allows each component to be optimized for its specific function while working together to achieve high reliability without excessive overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guiding track inherently provides its own guidance function through its fixed geometric structure, eliminating the need for external guidance systems or complex control mechanisms. The needle block assembly simply follows the predetermined path, making the system self-guiding and highly reliable.

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If precise needle guidance is implemented, then insertion accuracy improves, but ease of operation deteriorates

Engineering Contradiction:

Improveneedle insertion accuracyVSAvoidoperation simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The needle block assembly is designed to move dynamically along the guiding track, allowing the operator to easily slide it into position and lock it in place. This dynamic design maintains ease of operation while the fixed guiding track ensures high insertion accuracy, combining simplicity of use with precision.

Inventive Principle:

Principle #15Dynamics
