Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the field of view of a conventional laser system is changed to process different web material patterns, then the laser can accommodate different processing requirements, but the web path must be modified which is time-consuming and requires part kits for each setting

Engineering Contradiction:
Improvefield of view adjustment capabilityVSAvoidtime to modify web path
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies the Dynamics principle by making the laser system's field of view adjustable through a servo-driven mirror assembly that can dynamically change the laser beam's angle of incidence on the web material. This allows the system to adapt to different processing requirements without physical modifications to the web path, resolving the contradiction between adaptability and time loss.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements Parameter changes by varying the field of view angle of the laser system through servo control of mirror assemblies. By changing the angular parameter of the laser beam delivery system, the same physical web path can accommodate different processing patterns and fields of view, eliminating the need for time-consuming web path modifications and part kits.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the field of view is changed in a conventional laser system, then different processing patterns can be achieved, but the laser needs to be refocused to provide a focused beam at the new web path position

Engineering Contradiction:
Improvefield of view setting flexibilityVSAvoidrefocusing time
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies Dynamics by implementing a servo-driven focusing mechanism that can dynamically adjust the laser beam's focal position. When the field of view angle changes, the focusing mechanism automatically repositions the focal point to maintain it at the correct distance from the web material surface, eliminating manual refocusing time and maintaining productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements Feedback through a control system that coordinates the servo-driven mirror assembly and servo-driven focusing mechanism. The system receives information about the desired field of view setting and automatically adjusts both the beam angle and focal position to maintain optimal processing conditions, eliminating manual intervention and refocusing delays.

Inventive Principle:
Principle #23Feedback

3Device complexity

If a conventional laser system uses a fixed field of view, then the system structure is simple, but it requires web path modification and part kits for each different field of view setting

Engineering Contradiction:
Improvelaser system structureVSAvoidfield of view configuration options
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies Universality by designing a laser system with servo-driven mirror assemblies and focusing mechanisms that can perform multiple field of view configurations using the same physical hardware. Instead of requiring separate part kits for each field of view setting, the universal servo control system can dynamically configure the laser beam delivery to accommodate various processing patterns, reducing device complexity while maintaining versatility.

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