Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary laser beam is used to repel birds, then the device structure is simple, but the repellent effect is limited as birds become accustomed to the constant presence
Solution Approach 1:
The patent applies the dynamics principle by transforming the stationary laser beam into a moving laser beam. The frame housing the laser light source is made movable by drive means, causing the laser beam to sweep across the target area dynamically. This movement prevents birds from becoming accustomed to the repellent effect, thereby maintaining its reliability while the overall device structure remains relatively simple.
Solution Approach 2:
The patent implements periodic action through the oscillating or scanning movement of the laser beam. The drive means cause the laser beam to move back and forth or in circular patterns periodically, creating a dynamic repellent effect that renouvelles continuously. This periodic movement ensures birds cannot adapt to a fixed pattern, maintaining the repellent effectiveness without requiring complex device architecture.
2Reliability
If the laser beam is made to move to increase deterrent effect, then the repellent effectiveness improves, but the device complexity increases due to additional drive means
Solution Approach 1:
The patent makes the laser beam dynamic by coupling it to a movable frame with drive means. This dynamic configuration allows the laser beam to cover larger areas and prevent habituation, significantly improving the deterrent effect. The drive means, while adding some complexity, are integrated into the existing frame structure, minimizing the increase in overall device complexity.
3Area of stationary object
If a fixed frame is used, then the device is stable and easy to mount, but the laser beam covers limited area
Solution Approach 1:
The patent transitions from a fixed frame to a movable frame configuration. The drive means enable the frame to move, allowing the laser beam to sweep across a much larger coverage area. This dynamic frame arrangement maintains mounting simplicity while dramatically expanding the effective coverage area through motion.
Solution Approach 2:
The patent adds the dimension of time and motion to the previously static two-dimensional beam pattern. By making the frame movable, the laser beam covers not only a larger spatial area but also creates a temporal dimension of movement, effectively expanding the coverage from a fixed line to a sweeping area over time.
