Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the laser beam power is increased to reduce destruction time, then the destruction time is reduced, but the cost-effectiveness deteriorates beyond a certain power level

Engineering Contradiction:
Improvedestruction timeVSAvoidcost-effectiveness
Core Design Contradiction:
Duration of action of moving objectVSEase of manufacture

Solution Approach 1:

The patent replaces mechanical pod orientation with optical beam deflection using deformable mirrors. The deformable mirror can rapidly change beam direction without mechanical movement, achieving faster target switching while maintaining cost-effectiveness compared to increasing laser power.

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

Solution Approach 2:

The patent changes the parameter of beam direction control from mechanical (pod orientation) to optical (deformable mirror shape). This allows rapid adjustment of beam pointing angles without the inertia and speed limitations of mechanical systems, reducing destruction time without increasing laser power.

Inventive Principle:
Principle #35Parameter changes

2Speed

If the pod orientation speed is increased to switch between multiple targets, then the responsiveness is improved, but the mechanical complexity and speed limitations worsen

Engineering Contradiction:
Improvetarget switching speedVSAvoidmechanical complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent substitutes mechanical pod orientation with an optical beam deflection system using a deformable mirror. The mirror can be rapidly deformed electronically to change beam direction without mechanical movement of the entire pod, achieving high-speed target switching with reduced mechanical complexity.

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

Solution Approach 2:

The patent separates the functions of pod orientation and beam pointing. The pod provides coarse positioning while the deformable mirror provides fine, rapid beam direction control. This segmentation allows the heavy pod to remain stationary while the lightweight mirror handles rapid target switching.

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple laser weapons are deployed to destroy multiple flying objects simultaneously, then the destructive capacity is increased, but the cost increases

Engineering Contradiction:

Solution Approach 1:

The patent makes a single laser weapon system capable of simultaneously engaging multiple targets through rapid beam deflection. The deformable mirror enables the single laser to quickly redirect its beam between multiple targets, providing multi-functionality without requiring multiple weapon systems.

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

Solution Approach 2:

The patent enables a single laser weapon to serve itself for multiple targets through rapid beam steering. The deformable mirror allows the laser to automatically switch between targets without external intervention or additional weapons, reducing the quantity of weapons needed while maintaining destructive capacity.

Inventive Principle:
Principle #25Self-service
