Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple detection elements and movable assemblies are added to distinguish different surgical instruments, then measurement precision and reliability improve, but device complexity increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidsocket structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detection system is segmented into multiple independent indicator assemblies (first indicator assembly with first movable element, second indicator assembly with second movable element), each capable of independently detecting specific plug types. This segmentation allows precise differentiation of surgical instruments while keeping each individual detection element relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The indicator assemblies use movable elements that can dynamically change position (between first position and second position) based on plug insertion. This dynamic response provides clear visual feedback for detection without requiring complex fixed sensing mechanisms, resolving the contradiction between detection precision and structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If indicator assemblies with movable elements are implemented to detect plug insertion, then reliability of connection detection improves, but device complexity increases

Engineering Contradiction:
Improveconnection detectionVSAvoidsocket mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The movable elements in the indicator assemblies are designed to automatically respond to plug insertion through mechanical interaction. The plugs themselves activate the detection mechanism by their presence and positioning, eliminating the need for external power sources or complex electronic sensing systems. This self-service approach enhances reliability while maintaining mechanical simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The indicator assemblies provide visual feedback through positional changes that can be associated with different states (inserted/not inserted, correct/incorrect plug type). This visual indication system enhances reliability of connection detection without requiring complex electronic displays or sensors, resolving the contradiction between reliability and complexity.

Inventive Principle:
Principle #32Color changes

3Loss of information

If multiple indicator assemblies are used to differentiate between different surgical instrument plugs, then loss of information is reduced, but device complexity increases

Engineering Contradiction:
Improveinstrument type identificationVSAvoiddetection system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Different surgical instrument plug types are detected by separate, segmented indicator assemblies (first indicator assembly for first plug type, second indicator assembly for second plug type). Each assembly provides independent information about its specific detection target, ensuring complete instrument identification without requiring a single complex detection system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket is designed with universal capability to accept and detect multiple different plug types through its multiple indicator assemblies. Each indicator assembly can detect its specific plug type, and the combination provides comprehensive instrument identification. This multi-functional design reduces information loss about instrument type while avoiding the need for entirely separate detection systems for each instrument type.

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