Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external identification methods (barcodes, RFID) are used for component identification, then identification capability is provided, but the system becomes complex and prone to errors and wear

Engineering Contradiction:
Improveidentification reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the identification function from external systems (barcodes, RFID readers) and integrates it directly into the endoscope components themselves. The optical marking system is embedded within the endoscope structure, eliminating the need for separate external identification devices and reducing system complexity while maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The endoscope components perform their own identification using integrated optical markings and detection mechanisms. The system identifies itself without requiring external readers or additional equipment, making the identification process self-contained and reducing overall system complexity.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If components are made interchangeable for different applications, then adaptability is improved, but the risk of incorrect component combination increases

Engineering Contradiction:
Improvecomponent interchangeabilityVSAvoidcomponent compatibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses optical markings with distinct visual characteristics (analogous to color codes) to indicate different component types and compatibility requirements. These markings allow operators to quickly identify and select the correct components for specific applications while preventing incorrect combinations through visual differentiation.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The optical markings are applied to components during manufacturing, providing pre-established identification information that guides correct assembly. This preliminary marking allows for quick verification before use, ensuring compatibility without requiring complex verification procedures during the actual application.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If optical markings are placed on external surfaces, then identification is possible, but the markings are subject to manipulation and wear

Engineering Contradiction:
Improveidentification accessibilityVSAvoidmarking durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The optical markings are integrated within the endoscope structure itself rather than being applied as external coatings. The markings are embedded in the optical elements and housing, protecting them from manipulation and wear while remaining accessible for identification through the integrated optical detection system.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles
