Innovation Solution

A calibration mounting part-equipped surgical device featuring a sleeve with a hollow body and interchangeable design, including a chuck device part, holder part, and detachable calibration mounting part, which supports various medical tools and allows easy installation of calibration tools through a fastening method and rotation blocking mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individually manufactured sleeves are used for different cutter specifications, then compatibility with various cutters is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:
Improvecompatibility with various cuttersVSAvoidnumber of sleeves to be prepared
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal sleeve structure that can accommodate multiple cutter types (different lengths and diameters) through a standardized interface design. The sleeve includes a standardized mounting portion that interfaces with various cutters, allowing one sleeve design to serve multiple functions across different surgical procedures and cutter specifications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sleeve is divided into functional segments: a standardized mounting portion for cutter attachment and a support portion for structural stability. This segmentation allows the mounting interface to remain consistent while accommodating variations in cutter dimensions, reducing the need for completely different sleeve designs for each cutter type.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If individually manufactured sleeves are used for different cutter specifications, then compatibility with various cutters is improved, but manufacturing costs increase

Engineering Contradiction:
Improvecompatibility with various cuttersVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By designing a universal sleeve that can accommodate multiple cutter types through standardized interfaces, the system reduces the total number of unique components that need to be manufactured. This standardization enables economies of scale in production and reduces inventory complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If conventional sleeve design is used, then simple structure is maintained, but calibration tool installation and positioning accuracy deteriorate

Engineering Contradiction:
Improvesleeve structure simplicityVSAvoidcalibration accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The sleeve includes pre-formed calibration tool mounting features and positioning structures that are integrated into the basic sleeve design. These features are prepared in advance during manufacturing, enabling accurate calibration tool installation without requiring complex assembly steps or additional adjustment procedures.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If conventional sleeve design is used, then manufacturing simplicity is maintained, but calibration tool movement control deteriorates

Engineering Contradiction:
Improvesleeve manufacturing simplicityVSAvoidcalibration tool stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The sleeve incorporates pre-designed constraint structures such as positioning grooves, locking features, or friction-fit interfaces that are built into the manufacturing process. These features automatically constrain calibration tool movement when installed, providing stable positioning without requiring complex additional mechanisms.

Inventive Principle:
Principle #10Preliminary action
