Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of surgical light parameters is used, then surgeons can control lighting settings, but it requires continuous manual intervention that is cumbersome and inefficient

Engineering Contradiction:
Improvemanual control capabilityVSAvoidtime for parameter adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The surgical lighting system automatically adjusts its own parameters (illuminance, light spot size, angle) based on real-time detection of surgical field images or three-dimensional signals, eliminating the need for manual intervention and allowing the system to serve itself

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system detects surgical field characteristics through image signals or three-dimensional signals and uses this feedback information to automatically adjust lighting parameters, creating a closed-loop control system that responds to actual surgical conditions

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If fixed surgical light parameters are used, then device complexity is reduced, but it cannot adapt to different surgery types and stages

Engineering Contradiction:
Improveadaptation to different surgery typesVSAvoidparameter adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The surgical lighting system transitions from fixed parameters to dynamic, real-time adjustment of lighting parameters based on detected surgical conditions, allowing the system to adapt its characteristics continuously during different surgery types and stages

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system automatically modifies key lighting parameters (illuminance, light spot size, angle) based on analyzed surgical field information, enabling adaptation to different surgical requirements without manual intervention

Inventive Principle:
Principle #35Parameter changes

3Extent of automation

If automatic parameter adjustment is implemented, then hands-free operation is achieved, but system complexity increases

Engineering Contradiction:
Improveautomatic parameter adjustmentVSAvoidcontrol system structure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system replaces manual mechanical adjustment with automated control based on image processing and three-dimensional signal analysis, using computational algorithms to determine optimal lighting parameters instead of physical manual intervention

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
