Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual operation is used for laser treatment, then the operator can control the laser application, but the treatment accuracy and reliability are reduced

Engineering Contradiction:
Improvetreatment reliabilityVSAvoidmanual operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical operation with an automated robot arm system that precisely controls laser irradiation. The robot arm follows a pre-set guide path to deliver laser treatment, eliminating human hand-eye coordination errors and improving treatment reliability while maintaining operational control through automated programming.

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

Solution Approach 2:

The patent dynamically adjusts laser parameters (fluence and frequency) during the irradiation process based on real-time conditions. The control system modifies these parameters automatically to optimize treatment outcomes, replacing static manual settings with adaptive parameter control that enhances reliability.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If manual laser treatment is performed, then the operator can adjust treatment parameters, but the treatment time becomes excessively long

Engineering Contradiction:
Improvetreatment efficiencyVSAvoidtreatment time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent pre-calculates and pre-sets the optimal guide path and laser parameters before treatment begins. The robot arm and control system are prepared in advance with all necessary treatment data, eliminating time-consuming adjustments during the actual treatment process and significantly reducing overall treatment time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous laser irradiation along the pre-determined guide path without interruption or repeated positioning adjustments. The robot arm moves continuously while delivering laser energy, maximizing treatment efficiency and minimizing idle time compared to manual stop-and-start operations.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If laser fluence or frequency is increased at the beginning of irradiation, then treatment effectiveness improves, but stability decreases

Engineering Contradiction:
Improvelaser irradiation stabilityVSAvoidtreatment effectiveness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent employs dynamic parameter adjustment where laser fluence and frequency are automatically modified during the irradiation process. The system starts with lower parameters and gradually increases them, or maintains optimal levels based on real-time feedback, achieving both stability and effectiveness through adaptive control rather than static high-power irradiation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent systematically varies laser parameters (fluence and frequency) throughout the treatment process based on the guide path progression and tissue response. This controlled parameter evolution allows the system to achieve effective treatment outcomes while maintaining irradiation stability through programmed parameter transitions.

Inventive Principle:
Principle #35Parameter changes
