Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fiber optic cable is used for beam delivery, then the device structure is simple, but the ability to achieve desired laser beam configurations and power transmission is limited

Engineering Contradiction:
Improvebeam configuration capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention divides the beam delivery system into multiple independent fiber elements (10) instead of using a single fiber optic cable. Each fiber element can independently guide a laser beam, enabling flexible beam configurations such as arrays, patterns, or focused spots. This segmentation allows the system to achieve complex beam arrangements while maintaining the simplicity of individual fiber components.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple fiber elements are used to guide signal light radiation, then beam configuration flexibility is improved, but the device complexity increases

Engineering Contradiction:
Improvebeam configuration flexibilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention combines multiple fiber elements (10) into a single integrated beam guiding device (1) with common entry (11) and exit (12) elements. The fiber elements are fixedly connected at both ends, merging their functions into a unified structure that provides complex beam configuration capabilities while maintaining structural simplicity and ease of handling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The beam guiding device (1) serves multiple functions simultaneously: it guides multiple laser beams independently, enables various beam configurations (arrays, patterns, focused spots), transmits power efficiently, and can be integrated into existing laser systems. The fiber elements (10) themselves are universal components that can guide different wavelengths and power levels.

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

3Stability of the object's composition

If fiber elements are fixedly connected at both ends, then structural stability is improved, but manufacturing complexity increases

Engineering Contradiction:

Solution Approach 1:

The fiber elements (10) are pre-connected to the entry element (11) and exit element (12) in a controlled manufacturing process, establishing fixed connections before final assembly. This preliminary action ensures structural stability while allowing for standardized manufacturing procedures and quality control.

Inventive Principle:
