Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple laser heads are positioned to operate in separate non-overlapping areas, then collision avoidance is achieved, but operating efficiency and productivity are reduced

Engineering Contradiction:
Improvecollision avoidanceVSAvoidoperating efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The control system continuously monitors the real-time positions of multiple laser heads and dynamically adjusts their trajectories to prevent collisions while allowing overlapping operating areas. Position sensors and control algorithms provide feedback loops that enable safe concurrent operation in previously restricted configurations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transitions from static, pre-defined non-overlapping zones to dynamic, adaptive operating areas. Laser heads can enter overlapping regions temporarily under controlled conditions, with the system continuously recalculating safe operating parameters based on real-time positions and velocities of all heads.

Inventive Principle:
Principle #15Dynamics

2Productivity

If laser heads are arranged to maximize operating area coverage, then productivity increases, but programming complexity and control difficulty increase

Engineering Contradiction:
Improveoperating area coverageVSAvoidprogramming complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system automatically generates optimized toolpaths and collision avoidance strategies without requiring complex manual programming. The system self-adjusts by calculating optimal trajectories that maximize area coverage while inherently preventing collisions, reducing the burden on operators to manually program complex multi-head coordination.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system transforms the control problem by changing parameters from fixed, pre-programmed trajectories to dynamically adjusted paths based on real-time conditions. This allows simple programming of desired operating areas while the system automatically handles the complexity of coordination and collision prevention.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If base elements are designed as solid continuous structures, then structural stability is maintained, but fixture introduction and removal becomes difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoidfixture accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The base elements are segmented into modular sections with removable components or access points. This segmentation allows fixtures to be introduced and removed through designated openings while maintaining the overall structural integrity and stability of the base during operation.

Inventive Principle:
Principle #1Segmentation
