Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional rod connection methods are used, then spinal fixation stability is achieved, but operative time and procedural complexity increase significantly

Engineering Contradiction:

Improvespinal fixation stabilityVSAvoidoperative time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The connector assembly is divided into multiple independent components: a first component with a rod interface, a second component with a rod interface, and a coupling mechanism between them. This segmentation allows each component to be independently manufactured and assembled, reducing the time required for intraoperative contouring and fitting while maintaining the stability of the overall fixation system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector assembly incorporates adjustable and adaptable features that allow dynamic configuration during surgery. The components can be positioned and oriented to match the specific anatomical requirements of each patient, enabling quick adaptation without time-consuming custom contouring while ensuring reliable spinal fixation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If variable axis movements are allowed in pedicle screw recesses, then adaptability to different patient configurations is improved, but device complexity and operative time increase

Engineering Contradiction:

Improveadaptability to patient configurationVSAvoidcross-connector complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector assembly is divided into multiple independent components: a first component with a rod interface, a second component with a rod interface, and a coupling mechanism between them. This segmentation allows each component to be independently manufactured and assembled, reducing the time required for intraoperative contouring and fitting while maintaining the stability of the overall fixation system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector assembly is designed with universal features that can accommodate various rod configurations and patient anatomies through a single standardized design. The components can be oriented and positioned to provide the necessary adaptability without requiring multiple specialized tools or complex adjustment mechanisms, thereby reducing both device complexity and operative time.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If complex cross-connectors are used to connect bilateral rods, then spinal stabilization is achieved, but operational complexity and stress on surgical team increase

Engineering Contradiction:

Improvespinal stabilizationVSAvoidease of connector assembly

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connector assembly is divided into multiple independent components: a first component with a rod interface, a second component with a rod interface, and a coupling mechanism between them. This segmentation allows each component to be independently manufactured and assembled, reducing the time required for intraoperative contouring and fitting while maintaining the stability of the overall fixation system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector assembly acts as an intermediary element that simplifies the connection between bilateral spinal rods. By providing a pre-fabricated, modular interface with standardized connection mechanisms, it mediates the joining process in a way that reduces the skill level and time required compared to direct rod-to-rod connection methods.

Inventive Principle:

Principle #24Intermediary (Mediator)
