Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If moving optical components (mirrors, sensors) are used for scanning, then the field of view can be captured gradually, but mechanical complexity and maintenance needs increase
Solution Approach 1:
The patent replaces mechanical scanning systems (moving mirrors, rotating sensors) with a static sensor that uses electronically controlled lens tilting. The adaptive lens tilts in two directions to redirect light paths, achieving scanning functionality without any moving mechanical components in the optical path. This substitution eliminates mechanical complexity while maintaining the ability to capture a large field of view.
Solution Approach 2:
The patent uses dynamically adjustable lens tilting angles controlled by electronic signals to achieve scanning functionality. The adaptive lens can be tilted independently in two directions, allowing flexible scanning patterns without mechanical moving parts. This dynamic control provides the same field of view coverage as mechanical scanning but with simpler, maintenance-free operation.
2Reliability
If heavy moving masses are used for scanning, then reliable scanning movement can be achieved, but scanning patterns are limited due to inertia
Solution Approach 1:
The patent eliminates mechanical scanning components entirely, replacing them with electronically controlled adaptive lenses that tilt to redirect light. This substitution removes inertia limitations, allowing the system to implement any scanning pattern instantaneously by simply changing the lens tilting angles through electronic control, thereby achieving both reliability and scanning pattern versatility.
Solution Approach 2:
The patent changes the optical parameters (light path direction) by adjusting the lens tilting angles electronically. This allows instantaneous reconfiguration of scanning patterns without the mechanical inertia constraints that would limit speed and pattern changes in traditional systems. The scanning behavior is controlled by electrical parameters rather than mechanical motion.
3Manufacturing precision
If electromechanical focus adjustment is used, then precise focus positioning is achieved, but installation space and mechanical structure requirements increase
Solution Approach 1:
The patent replaces electromechanical focus adjustment mechanisms with an adaptive lens system that achieves focus control through optical parameter changes. The adaptive lens can be tilted and its focal properties adjusted electronically without requiring large mechanical structures or significant installation space, while maintaining precise focus positioning capability.
Solution Approach 2:
The patent uses parameter changes in the adaptive lens (tilting angle and focal length adjustment) to achieve precise focus positioning. This electronic parameter control eliminates the need for large mechanical focus adjustment mechanisms, reducing installation space requirements while maintaining or improving focus precision through direct optical control.
