Solution Overview

Problem

Surgical instruments often experience particulate contamination during manufacturing and transportation, leading to concerns about functionality and potential discarding of otherwise functional devices.

Innovation Solution

The implementation of actively adherent internal surfaces within the surgical instrument's housing, combined with a selectively removable cover over the opening, captures and retains particulates, preventing them from exiting the housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If openings are provided in the housing for functionality, then the instrument can operate properly, but particulates may exit the housing through these openings

Engineering Contradiction:
ImprovefunctionalityVSAvoidparticulate contamination
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

An actively adherent coating is applied as an intermediary layer on the internal surfaces of the housing, particularly around the openings. This coating acts as a mediator that captures particulates through adhesion, preventing them from exiting through the functional openings while maintaining the openings' operational integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the surface properties of the housing interior by applying an actively adherent coating. This parameter change transforms the surface from a non-adherent state to an actively adherent state, enabling it to capture and retain particulates through chemical or physical adhesion mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If particulates are captured and retained, then the instrument functionality is protected, but the device complexity increases

Engineering Contradiction:
Improvefunctionality protectionVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The actively adherent coating provides self-service by automatically capturing and retaining particulates through its inherent adhesion properties. The coating continuously monitors and captures particulates without requiring external mechanical systems, sensors, or active control mechanisms, thereby maintaining reliability while minimizing added complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

By changing the surface parameter of the housing interior through coating application, the system achieves particulate capture functionality without adding complex mechanical structures. The parameter change enables a passive, low-complexity solution that protects reliability through material property modification rather than system complexity increase.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If the housing is sealed to prevent particulate exit, then particulate contamination is reduced, but the openings necessary for functionality are blocked

Engineering Contradiction:
Improveparticulate containmentVSAvoidfunctional opening access
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The actively adherent coating is applied locally to specific areas of the housing interior, particularly around and near the functional openings. This local quality approach ensures that the coating captures particulates in the critical zones where they would otherwise exit through the openings, while the openings themselves remain unobstructed and fully functional.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The coating serves as an intermediary layer that exists between the particulates and the openings. It intercepts and captures particulates through adhesion, preventing them from reaching the openings while allowing the openings to maintain their structural integrity and functional accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)
