Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lens with a single focus length is used, then the lens structure is simple, but the sensor coverage range is limited and cannot fulfill applications requiring different focus lengths
Solution Approach 1:
The lens is divided into multiple layers, with each layer containing refraction portions with different refraction angles. This segmentation allows the lens to handle multiple focus lengths simultaneously, expanding sensor coverage range while maintaining a manageable structured through systematic division of optical functions across layers.
Solution Approach 2:
The invention transitions from a conventional single-layer lens to a multi-layer structure, adding the dimension of layer stacking. Each layer contributes different refraction angles, effectively using vertical stacking to achieve what would otherwise require multiple separate lenses, thus expanding coverage without proportionally increasing horizontal complexity.
2Reliability
If a lens with multiple layers and concentric refraction elements is used, then sensed signal strength is enhanced and coverage range is enlarged, but the device complexity increases
Solution Approach 1:
Multiple refraction portions with different refraction angles are merged into a single multi-layer lens structure. This consolidation allows the lens to enhance sensed signal strength by capturing signals from multiple angles simultaneously, while avoiding the need for multiple separate lenses, thus improving reliability without proportionally increasing overall device complexity.
Solution Approach 2:
The lens employs a nested structure where multiple layers are stacked concentrically, with each layer containing refraction portions arranged in a nested manner. This nesting allows efficient use of space, enabling enhanced signal detection through multiple refraction angles while maintaining a compact form factor that limits the increase in device complexity.

AI summary
The lens contains a cup-shaped body with a lens bottom and a lens member extended upward from the lens bottom and forming a 49-degree included angle with the lens bottom. The lens member contains, from bottom to top, a number of layers, each having a number of refraction portions. Each refraction portion contains a number of refraction elements arranged in a concentric manner. According to the inclination angle of the lens member, dimensions of the refraction portions, and the distribution of refraction elements, the lens could be applied to various applications with enhanced coverage range and sensory effect.
