Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual fine adjustments are performed by skilled personnel, then adjustment precision and quality are maintained, but labor costs increase and productivity decreases

Engineering Contradiction:
Improveadjustment precisionVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical adjustment operations with an automated regulating machine that uses motorized positioning modules, vision systems, and laser measurement systems to perform fine adjustments on watch oscillators, thereby maintaining precision while eliminating manual labor constraints

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

Solution Approach 2:

The regulating machine incorporates self-positioning capabilities through vision systems and laser measurement that automatically detect and locate target components on watch assemblies, enabling the system to perform adjustments autonomously without continuous human intervention

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If multiple successive elementary adjustments are performed to achieve high chronometric quality, then adjustment accuracy is improved, but adjustment time increases

Engineering Contradiction:
Improvechronometric qualityVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent implements continuous automated adjustment operations where the regulating machine performs multiple adjustment iterations without interruption, using motorized positioning and automated feedback control to achieve high chronometric quality in a single continuous process rather than through multiple discrete manual steps

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The regulating machine incorporates vision systems and laser measurement systems that provide real-time feedback on component positions and adjustment results, enabling automated closed-loop control that achieves high precision adjustments in fewer iterations by continuously monitoring and correcting positioning errors

Inventive Principle:
Principle #23Feedback

3Productivity

If automated positioning systems are implemented, then productivity and precision are improved, but device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The regulating machine employs multi-functional modules that perform multiple operations: positioning modules handle both coarse and fine positioning, vision systems perform both detection and measurement, and laser systems provide both ranging and alignment functions, thereby reducing the total number of separate components needed despite the sophisticated automation capabilities

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

Solution Approach 2:

The patent implements a hierarchical modular architecture where positioning modules, vision systems, and laser measurement systems are nested within an integrated control framework, with each module independently functional but coordinated through a central control system, allowing complex functionality to be achieved through organized composition of manageable subsystems

Inventive Principle:
Principle #7Nested doll (Nesting)
