Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rotating or oscillating mirrors are used to redirect light signals, then light signals can be redirected and scanning can be performed, but the device complexity increases and reliability decreases
Solution Approach 1:
The patent employs a curved displacement path for the redirection body instead of traditional rotating or oscillating mirror mechanisms. This curved path allows the redirection region to change the angle of incidence of light signals while following a predetermined trajectory, achieving scanning functionality without complex mechanical rotations or oscillations. The curvature of the displacement path inherently provides the angular variation needed for light redirection.
Solution Approach 2:
The invention replaces the traditional mechanical rotating or oscillating mirror system with a drive device that moves the redirection body along a curved displacement path. This substitution reduces mechanical complexity by eliminating the need for complex rotational joints, bearings, and oscillation mechanisms, while achieving the same light signal redirection effect through controlled linear or curved motion.
