Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex irrigation and suction control apparatuses are used, then functional reliability is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvefunctional reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines irrigation and suction control functions into a single integrated apparatus. The control unit integrates both irrigation control (first tube, first pump) and suction control (second tube, second pump) functions, eliminating the need for separate control devices while maintaining functional reliability through unified management of both fluid delivery systems

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The control unit serves multiple functions: it controls irrigation fluid delivery through the first tube, manages suction through the second tube, monitors fluid levels via sensors, and coordinates pump operations. This multi-functional design reduces the number of separate devices needed while maintaining comprehensive control over surgical fluid management

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If complex irrigation and suction control apparatuses are used, then functional reliability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvefunctional reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs optical sensors that detect fluid levels and presence through light absorption and reflection changes. The sensor system uses optical properties (light transmission/blockage) to monitor irrigation fluid and suction conditions, enabling reliable detection without complex mechanical or electronic sensing mechanisms, thereby reducing manufacturing costs

Inventive Principle:

Principle #32Color changes

3Reliability

If complex irrigation and suction control apparatuses are used, then functional reliability is improved, but ease of operation decreases

Engineering Contradiction:

Improvefunctional reliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The control unit automatically monitors and adjusts irrigation and suction operations based on sensor feedback. The system self-regulates fluid delivery and removal rates, detects blockages or fluid level issues, and coordinates pump operations without requiring constant manual intervention, thereby maintaining functional reliability while simplifying operator workload

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent incorporates sensors that continuously monitor irrigation fluid levels, suction conditions, and system status. This feedback is processed by the control unit, which automatically adjusts pump operations and fluid delivery rates to maintain optimal functioning, reducing the need for manual monitoring and adjustment by the operator

Inventive Principle:

Principle #23Feedback
